SUMMARY

Conventional tillage practices lead to change in soil structure by modifying soil bulk density and soil moisture content. Continuous disturbance of soil by conventional tillage makes finer and loose-setting soil structure while conservation and no-tillage methods leave the soil intact which results in a change of characteristics of the pores network. Losses of soil organic C (SOC) and deterioration in other properties exaggerated where conventional tillage was employed whereas conservation tillage improved soil quality. When conventional tillage is replaced by conservation tillage CO2 emissions from soil is reduced. Conservation tillage is thought to take care of the soil health, plant growth and the environment. Forage crop production could be increased by adopting appropriate tillage operation. Conservation tillage has potential to break the surface compact zone in soil with reduced soil disturbance which leads to a better soil environment and crop yield with minimal impact on the environment and sustainable crop production. Macro- and micronutrients, fiber and protein contents are changed in silage by means of different tillage practices. Generally, conservation tillage has profound effects on forage yield. Zero tillage with mulch, zero tillage without mulch, ploughing, and ploughing plus harrowing had more yield than ploughing plus harrowing twice by 33.7, 30.5, 18.9 and 17.9%, respectively. Conservation tillage lead to lower methane emission in comparison to conventional tillage; on average, 0.32 kg CH4-C ha-1 year-1 was oxidized with conservation tillage. Capacity building on innovative conservation tillage practices is crucial for researchers, extension workers, development practitioners and the smallholder farmers.

SUMMARY

Maize (Zea Mays) plant is affected by number of foliar diseases among of them, Southern Corn Leaf Blight (SCLB) or Maydis Leaf Blight (MLB) incited by the Helminthosporium maydis anamorph: Bipolaris maydis, telomorph: Cochliobolus heterostrophus is one of the most devastating disease of maize in India as well as in the world. Three different races namely race O, T and C of helminthosporium are found responsible for causing this disease. Bipolaris has the potential to reduce the yield significantly up to 70% depending upon the susceptibility, race of pathogen and environmental conditions.Genetic architecture of maize possess the diverse source of resistance against Helminthosporium which are qualitative, quantitative and multiple disease resistance types in nature but often represents quantitative nature of resistance. A single gene, rhm, imparts a qualitative-like resistance against race O which inherits recessively with additive gene action predominantly. It is implied at the seedling stage but quantitative resistance is needed after silking stage. An additional two resistance genes have been identified in the inbred NC250 that are not allelic to rhm and this resistance is maintained in mature plants. Plenty of attempts have been made to identify the resistance source and to dissect the quantitative trait loci (QTL) responsible for resistance or multiple disease resistance to SLB across different maize populations. QTLs responsible for multiple disease resistance were identified of elucidated with the help of meta analysis of available studies.

SUMMARY

Pearl millet is a major cereal crop in northwestern India. It is the most drought-tolerant cereal grown in the arid and semi-arid regions. Its grains are valued as human food while its fodder makes important livestock ration in crop–livestock farming system. The production potential of rainfed pearl millet is continued to be low as a result of frequent drought due to high variability in rainfall (amount and distribution) during the growing season, low soil fertility, low plant nutrient use, and poor socio-economic conditions of farmers, could not use high technology input. This review mainly highlighted various improved practices for increasing productivity and profitability of fodder and grain type pearl millet. It includes soil moisture conservation practices by practicing the improved planting methods, supplemental irrigation, use of improved varieties, and intercropping. Integrated use of fertilizer and use of low energy input for enhancing the crop productivity.

SUMMARY

The aim of this work was to make an inventory of the aromatic plants pastured by goats in the Aurès Mountains of Algeria and to characterize their volatile and phenolic compounds. In this context, a survey was conducted among goat farmers in this region (department of Batna). Plant volatile compounds were analyzed using HS-SPME/GC-MS and phenolic compounds using HPLC-DAD. According to the results of the survey, twenty-nine (29) aromatic plants were identified as goats’ feed. The most cited ones were Thymus algeriensis (96 %), Artemisia herba alba Asso (91 %), Rosmarinus officinalis L. (83 %), Juniperus phoenica L. (80 %), Artemisia campestris L. (80 %), and Marrubium vulgare L. (70 %). The major volatile compounds were -pinene (40 %), -thujone (38 %), trans-caryophyllene (31 %), -myrcene (29 %), camphor (27 %), and -thujone (18 %). The most abundant phenolic compounds were flavonoids (rutin, kaempferol-3-O-rutinoside, apigenin, hesperidin, isoquercitrin, and quercitrin), cinnamic acid derivatives (chlorogenic acid, rosmarinic acid, caffeic acid, and ferulic acid), coumarines, and benzoic acid derivatives. The present results indicate that aromatic plants from Aurès mountains of Algeria are rich in phenolic compounds and could be offered as feed for goats.

Six genotypes of Hybrid Napier Grass (TNCN 1280, BNH 14, BNH 22, PBN 351, BNH 12 and BNH 11) alongwith three national checks viz. CO 3, CO (BN) 5 and NB 21 were evaluated for assessing their fodder yield potential and quality parameters at CCS Haryana Agricultural University, Hisar, Haryana, India. The hybrid Napier grass genotype BNH 11 gave highest GFY (1050.6 q/ha) followed by TNCN 1280 (1027.7 q/ha) in comparison to mean value of best check CO (BN) 5 at 953.9 q/ha. Similarly, genotype BNH-11 gave highest DMY (243.8 q/ha) followed by PBN 351 (240.6 q/ha) in comparison to mean value of best check CO (BN) 5 at 221.0 q/ha. The highest green fodder yield (2267.3 q/ha) pooled over three years was recorded at Urulikanchan in central zone followed by Coimbatore (1908.7 q/ha) and Vellayani (1886.4 q/ha) in the south zone of India in comparison to mean All India GFY (999.4 q/ha), whereas, the highest pooled dry matter yield (520.8 q/ha) was recorded at Urulikanchan in central zone followed by Vellayani (469.1 q/ha) and Coimbatore (383.3 q/ha) in the south zone in comparison to mean All India DMY (229.8 q/ha). Highest per day production of green fodder pooled over three years was recorded in South zone (7.98 q/ha/day) followed by North West zone (5.94 q/ha/day). Almost same trend was observed for per day production of dry matter (q/ha/day). The highest crude protein yield pooled over three years was obtained at Urulikanchan (34.3 q/ha) followed by Ludhiana (20.5 q/ha) in the Central and North west zone, respectively with a mean value at 13.3 q/ha. Highest crude protein percent pooled over three years was obtained at Ludhiana (8.5%) followed by Rahuri (8.4%) in comparison to all India mean of 7.3%. The genotype BNH 12 gave highest IVDMD% pooled over three years (54.7%) followed by BNH 11 (53.4%) in comparison to mean value of best check CO (BN) 5 at 53.3%. The genotype BNH 12 gave lowest NDF% (62.5%) followed by BNH 11 (63.4%) in comparison to mean value of best check CO (BN) 5 at 64.9%. The hybrid Napier grass genotype BNH 12 had the lowest ADF% (45.4%) in comparison to mean value of best check CO 3 at 46.3%. Data reveals that South zone gave highest green fodder and dry matter yields followed by Central zone of India thereby indicating that climatic and edaphic conditions are very suitable for hybrid Napier grass as compared to North West and North East Zone of India.

SUMMARY

The present investigation was undertaken at Upland Research cum Instructional Farm, Lamker, SGCARS, IGKV, Raipur in Kharif 2018-19 with 100 germplasm accessions to evaluate the forage potential of finger millet (Eleusine coracana L.) in augmented randomized block design. Mean squares for analysis of variance indicated significant differences among blocks, check and test entries for crop duration, canopy length and fodder weight. The maximum canopy length was recorded in genotype GEC-5 (126cm) followed by GEC-186 (125 cm), GEC-92 (124 cm), GEC-310 (122 cm), GEC-314 (120 cm) and others. Referring to crop duration, genotype IC0476378, IC0477043, GEC-322, GEC-11, IC0477620, GEC-296, GEC-53 and GEC-352 can be considered as good for medium fertile soil and average monsoon regions in lieu of mid-durational maturity. For fodder yield, IC0476495 (1646 g/plot) was recorded as most dominating genotype referring to the breeding objective and subsequently GEC11 (1222 g), GEC92 (1112 g), IC0477620 (1042 g), GEC132 (1027 g) and IC0477556-X (990 g) also showed fair potential. To get establish general crop growth parameters in association with fodder as objective, we conclude that 95-105cm of canopy length and 105-115 DAS of crop may be opted to achieve the maximum forage potential in finger millet. We further suggest that IC0476495, GEC11, GEC92, IC0477620, GEC132, IC0477556-X, IC0476838, IC0477317, GEC274, IC0477560, IC0477591 and GEC135 shown good potential and should be revalidated in next crop season followed by incorporation in replicated trials.

SUMMARY

The study involving twenty-eight genotypes of Anjan grass with two checks were evaluated in a Randomized Block Design with two replications at Grass Breeding Scheme, Mahatma Phule Krishi Vidyapeeth, Rahuri, Dist. Ahmednagar, Maharashtra. Treatment differences were found to be significant for all the characters studied. High estimates of GCV and PCV were observed for traits viz., number of tillers/plant, leaf breadth, spike length and number of spikes per plant. High estimates of heritability (b.s.%) accompanied by high estimates of genetic advance as percentage of mean were observed for the characters namely number of tillers/plant, number of leaves/tiller, leaf length, leaf breadth, spike length, number of spikes/plant, spikelets per spike and green fodder yield. The characters like plant height, number of tillers per plant, leaf length, leaf breadth, spike length, spike breadth, spikelets per spike and dry matter percent showed significant positive genotypic and phenotypic correlations with green fodder yield. Leaf length exhibited high positive direct effect and significant positive genotypic correlation with green forage yield followed by leaf breadth, plant height, number of tillers per plant and spike breadth. The characters spike length, spikelets per spike and dry matter also exhibited high negative direct effects on green fodder yield, however its association with green fodder yield observed to be strong and positive. Thus indicating that emphasis should be given on these characters for green forage improvement in Anjan grass.

SUMMARY

Salt stress has been considered a major limiting factor to crop productivity in arid and semi-arid regions. The present study was conducted to evaluate the sorghum genotypes superior in quality and yield under saline conditions. The two factor experiment was carried out in a completely randomized block design with three replications during the kharif season 2018 and 2019. Crude protein content and IVDMD decreased significantly under different salinity levels. The higher reduction being reported in PC-5 than SSG 59-3. Crude protein yield (CPY) and digestible dry matter (DDM) was maximum in SSG 59-3 and minimum in PC-5 at 10 dSm-1. Salt stress showed an adverse effect on yield attributes and yield, so seed yield per plant, green fodder yield (GFY), and dry matter yield (DMY), decreased under salt stress. GFY and DMY were maximum in SSG 59-3 while minimum in PC-5. Better performance was maintained by SSG 59-3 than PC-5. This, SSG 59-3 (salt-tolerant) genotype acclimated better than PC-5 (salt-sensitive) genotype by maintaining the fodder quality and yield and may be exploited in plant breeding programs aimed at developing salt-tolerant sorghum genotypes for salinity prone areas.

SUMMARY

Present investigation was carried out during Rabi season of 2018-19 at Wheat Section Research Area of CCS Haryana Agricultural University, Hisar. The experiment was laid out in split plot design with four replications. In main plot, three cutting schedules i.e. 45 DAS, 55 DAS and 65 DAS were taken and six nitrogen schedules i.e. N1– 1/3 basal +1/3 at first irrigation and 1/3 after cut, N2– ½ basal + ½ at first irrigation, N3-½ basal and ½ after cut, N4– ¼ basal +½ at first irrigation and ¼ after cut, N5 – ½ basal +¼ at first irrigation and ¼ after cut, N6 – ¼ basal +¼ at first irrigation and ½ after cut as sub plot treatments. Based on the research findings, it was observed that different cutting and nitrogen schedules significantly influenced the growth, yield attributes and yield of dual-purpose wheat. Crop cut at 45 DAS for green fodder resulted in significantly higher plant height, dry matter accumulation (415.0 g), number of tillers (112.2 /mrl), number of effective tillers/mrl (102.87), grains per spike (47.61) and 1000 grain weight (42.57g) as compared to crop cut at 55 DAS and 65 DAS. Crop cut at 45 DAS for green fodder also produced maximum grain yield (61.36 q/ha) and straw yield (98.12 q/ha), which were significantly higher than cut at 55 and 65 DAS. Whereas, minimum grain yield (47.42 kg/ha) was recorded when crop cut was taken at 65 DAS for green fodder. Among different nitrogen schedule, N3 resulted in maximum plant height (106.9 cm), dry matter accumulation, number of tillers (109.0), number of effective tillers (100.50), grain per ear head and 1000-grain weight. Similarly, maximum grain yield (56.88 q/ha) was recorded when half nitrogen dose was applied as basal and half dose of nitrogen was applied just after cut (N3) which was significantly higher than N2 and N5 but it was at par with N1, N4 and N6. Whereas, minimum grain yield (54.09 q/ha) was recorded with N2 treatment. However, maximum straw yield (98.12 qha-1) was recorded with N1 being at par with N3 and N6 but significantly higher as compared with rest of the nitrogen schedule.

SUMMARY

Efficient sources of nutrients supplying the nutrients with greater efficacy and high yielding pearl millet hybrid with nutrient responsiveness plays an important role in yield enhancement and quality improvement on pearl millet in the arid region under sandy loam soil. To find out the influence of customized fertilizers and hybrids on growth and yield of pearl millet, field experiments were carried out during kharif seasons of 2019 and 2020 at ICAR-All India Coordinated Research Project on Pearl Millet, Research Farm, Agricultural Research Station, Mandor, Jodhpur (Agriculture University, Jodhpur). Customized fertilizer substantially enhanced growth attributes viz., plant height (200.8 and 183.5 cm), days to panicle initiation (23.0 and 22.7 days), days to 50% flowering (46.8 and 44.7 days), days to maturity (86.7 and 83.8 days) during 2019 and 2020, respectively over control. Application of customized fertilizer recorded markedly higher grain yield (2124 and 1896 kg/ha) and straw yield (3611 and 3223 kg/ha) during 2019 and 2020 over control and straight fertilizer. Among hybrids, substantially taller plants were observed by the pearl millet hybrid ‘MPMH 17’ (192.6 cm) during 2019 and ‘RHB 173’ (171.6 cm) during 2020. The hybrid ‘RHB 173’ took a greater number of days to panicle initiation (23.8 and 23.7 days), days to 50% flowering (49.1 and 48.0 days) and days to maturity (84.3 and 82.2 days) during 2019 and 2020. Economic analysis envisages, application of customized fertilizer fetched significantly higher gross return ( 60,528 and 56,872/ha), net return ( 34,072 and 36,307/ha) and B: C ratio (2.75 and 2.49) during 2019 and 2020 over control. Likewise, markedly higher gross return ( 60,109 and 55,638/ha), net return ( 40,361 and 35,061/ha) and B: C ratio (3.02 and 2.68) was obtained by hybrid, ‘MPMH 17’ during 2019 and 2020.

Treatments comprised of four phosphorus levels in main plot i.e. Control, 7.5 kg P2O5/ha, 15 kg P2O5/ha and 22.5 kg P2O5/ha and four zinc levels in sub plot viz. Control, 0.50 % foliar spray of ZnSO4 at 20-25 DAS, 0.75 % foliar spray of ZnSO4 at 20-25 DAS and 25 kg ZnSO4/ha as basal dose. It was observed that significantly higher plant height and number of tillers/meter row length were recorded with application of 22.5 kg P2O5 ha-1 and 25 kg @ ZnSO4/ha at 20, 40 and 60 DAS over comtrol. Further, the green and dry fodder yield of sorghum was significantly influenced by different levels of phosphorus. Application of 22.5 kg P2O5 ha-1 recorded significantly higher the green and dry fodder yield over 7.5 kg P2O5/ha, 15 kg P2O5/ha and control treatments. The basal application of ZnSO4 @ 25 kg/ha recorded significantly higher green and dry fodder yield of forage sorghum over foliar applications of ZnSO4 @ 0.50 %, 0.75 % and control. Crude protein content of forage sorghum was improved progressively with increasing levels of phosphorus and zinc.

SUMMARY

A study was conducted during kharif season of 2020 on sandy loam soils of forage research farm of PAU, Ludhiana to study the interactive effects of different fertility levels {control, 50:10:12.5, 100:20:25 (recommended dose of fertilizers) and 150:30:37.5 kg N: P2O5: K2O per ha} and five genotypes (SPV 2584, SPV 2587, SPV 2593, CSV 21F and CSV 30F) on growth, yield, quality and disease incidence of single cut forage sorghum. The experiment was laid out in Randomized Complete Block Design (RCBD), using three replications. It was revealed from the results that SPV 2584 owing to its profused tillering gave highest green fodder yield to the tune of 76.4% over the check genotype CSV 30F. The genotypes SPV 2593 and CSV 21F remained statistically at par with SPV 2584 with regards to green fodder productivity. The genotype SPV 2584 also remained superior in terms of quality of green fodder recording highest value of crude protein content (6.36%) and lowest value of hydrocyanic acid (44.7%) over other genotypes. The effect of fertility levels was found to be significant upto 100:20:25 kg NPK/ha giving 21.6 and 26.6% increase in green fodder and dry matter yield, respectively with 50 percent increase in fertility level. The quality of forage sorghum increased with increase in fertility level with corresponding increase in HCN also. The effect of fertility and genotypes on disease severity was found to be significant and highest disease reduction of anthracnose (35.1%) was recorded with application of 100:20:25 kg NPK/ha.

SUMMARY

A field experiment was conducted during two consecutive kharif seasons (2019 and 2020) at Agricultural Research Station, Navgaon (Alwar), S.K.N. Agriculture University, Jobner, Jaipur (Rajasthan), India, to study the effect of different intercrops in pearl millet (bajra). The experiment was laid out in a randomized block design with ten treatments and replicated thrice. The crop was sown as per the package of practices recommended for zone III-B of Rajasthan. Treatments included Bajra + mung bean (2:1), Bajra + mung bean (4:2), Bajra + black gram (2:1), Bajra + black gram (4:2), Bajra + Cluster bean (2:1), Bajra + Cluster bean (4:2) including sole bajra, mung bean, black gram and cluster bean. Among the different intercropping treatments, Bajra + mung bean (4:2) recorded significantly higher pearlmillet equivalent yield (15.69 q/ha in 2019 and 15.79 qt/ha in 2020) with higher economic efficiency. The intercropping of pearl millet + mung bean (4:2) recorded significantly higher net monetary return (Rs.15184 ha-1) than all other intercropping systems. The mean maximum benefit-cost ratio (1.87) was also recorded by pearl millet + mung bean (4:2).
