SUMMARY

Food security for a huge country like India, with high density of population in general and below poverty line is of vital importance. India has to produce around 300 mt of food grains by 2025 A.D. to nourish over 1.4 billion population from 0.15 ha land per capita or less. To feed this burgeoning population, many intensively cropped cereal based cropping systems are under cultivation in the country. Pearl millet [Pennisetum glaucum (L.) R. Br. Emend. Stuntz.] – wheat (Triticum aestivum L.) is one of the important cropping systems of the country and spreads over arid eco-region; semi-arid eco-region with alluvium derived soils. Higher food production needs higher amount of plant nutrients. To avoid wastage of resources and to reduce the environmental damage, there is a need to develop and demonstrate balanced use of organic/inorganic fertilizers. This will not only ensure the crop production in a sustainable way but also sustain the crop production system. As no single source of nutrient is capable of supplying the balanced amount of nutrients, integrated use of all sources is a solution to supply balanced nutrients. Long term studies being carried out at several locations on different cropping systems indicated that application of all the needed plant nutrients through chemical fertilizers has deleterious effect on soil health. Since, the nutrient turnover in soil-plant system is considerably high under intensive cropping system. So, neither the chemical fertilizers nor the organic/biological sources alone can achieve production sustainability. Even with the so called balance use of NPK fertilizers in long term studies, higher yield levels could not be maintained for years because of emergence of secondary and micro-nutrient deficiency and deterioration in the soil physical properties. Organic manure alone or in combination with inorganic fertilizers are known to have favourable effect on soil and can correct marginal deficiency of secondary & micro-nutrients and interns will ensure efficient supply of applied nutrients. Therefore, there is need to strengthen nutrient supply system especially through INM for sustainable production of this cropping system. Use of chemical fertilizers in conjunction with FYM, vermicompost, green manure, wheat straw etc. have proven good for sustainability of pearl millet- wheat cropping system which have been thoroughly discussed in this review.

SUMMARY

At present time, scope to increase area under forage crops cultivated is limited; the reason is increasing day by day pressure and preference of people for food and commercial crops. But India is a home to about 512 million livestock population also. Hence, the per unit production of fodder crops should be increased to feed this huge livestock population. Growth, development and biological yield of the crops affected by the balanced use of fertilizers shows positive effects over use of nutrients in single and in combination. Importance of micronutrients for upholding soil health and boosting crops productivity is well known. A very small amount of these micronutrients is required. For desired growth and development of plants the soil must supply micronutrients. Adoption of HYVs (high yielding varieties) results increased removal of micronutrients and intensive cropping results in high application of NPK fertilizers which is the reason behind below normal level of micronutrients in soil at which sustainable crop productivity cannot be achieved. Zinc and iron play an important role in crop nutrition and thought to be necessary for plant development and production, as their role in plant auxins bio-synthesis, oxidation-reduction reactions, plant nitrogen metabolism, formation of chlorophyll, respiration, chief enzyme system and photosynthesis in plants. Economical and efficient way of getting micronutrients into the crop production system is application of fertilizers having micronutrients through soil which requires higher quantity of micronutrients as compare to foliar application. The method of foliar application is broadly used in many crops. Soluble salts are mainly used for foliar sprays. Deficiency symptoms can be corrected within few days by foliar application of micronutrients and at time of new crop sowing the appropriate micronutrients source is applied to the soil

SUMMARY

Conservation and sustainable use of forage species is important for increasing livestock productivity and ensuring food security in mixed crop-livestock production systems of smallholder farmers. This study was conducted to evaluate nutritive values of selected grass and forbs in Tikur Inchini District West Shoa Zone, Oromia, Ethiopia. Ten selected herbaceous species were identified by knowledgeable local farmers. Sample of the selected species were collected at 50% flowering, full flowering and post flowering stages and their nutritive values were analyzed at Holeta Research Center, Animal Nutrition Laboratory following established procedures. Semi-structured questionnaire was prepared and perceptions of farmers were documented. The data were analyzed using excel spreadsheet, and SPSS version 20. Mean CP of forbs (7.68%) was higher than that of grasses (6.58%). On the other hand, mean NDF and ADF content were higher in grasses (65.04 and 49.03%, respectively) compared with the contents in forbs (62.13 and 45.41%, respectively). The result showed that there was significant difference (p<0.05) between the grass and forb species. The low CP content in the study area could be due to continued rangeland degradation as a result of overgrazing. It was noted that there was positive correlation between the indigenous knowledge of farmers and laboratory results on nutritive value of some forage species. Farmers perceived that highly desirable forage species such as Sporobolus affinis, Satureja punctata, and Cynodon spp were threatened due to expansion of crop land and overstocking. Conservation and sustainable use of forage species, rangeland rehabilitation, improving livestock management to minimize overgrazing and increasing options for feed availability from diverse sources were recommended as a result of this study.

SUMMARY

Pearl Millet [Pennisetum glaucum (L.) R.Br.] is one of the staple food and fodder crop of the arid and semi-arid regions of Africa and Asia. Pearl millet displays enormous phenotypic and genotypic diversity. Assessment of available genetic diversity in pearl millet through the use of molecular markers will supplement the conventional breeding programme. Keeping this in view, the present study was undertaken to evaluate genetic diversity among forty eight maintainer lines of pearl millet with twenty two SSR primers which produced a total of 85 alleles. Three out of twenty two polymorphic primers showed PIC value of more than 0.70 i.e. Xpsmp2066, Xpsmp2089 and Xpsmp2063. The maximum number of ten amplified products was observed in the profiles of the primer Xpsmp2001. The highest PIC value is observed for Xpsmp2089 with value (0.78). The molecular data grouped the forty eight genotypes of pearl millet into eight main clusters which revealed considerable genetic diversity among the maintainer lines. Among the eight clusters, cluster II was the largest comprising eighteen genotypes. So, SSRs are effective markers for the assessment of genetic diversity in maintainer lines of pearl millet. The diversity assessed can be manipulated to broaden the genetic base of maintainer line for the development of commercial hybrid varieties.

SUMMARY

A field experiment entitled “Response of hybrid maize to spacing and fertility management” was conducted at Maize Research Station, S. D. Agriculture University, Bhiloda (Gujarat) for three kharif seasons (2014-2017) in loamy sand soil. The experiment laid out in split plot design comprised of two main and one sub-factor treatments arrangement with three replications. Between two varieties, V1 (CO 6) produced significantly higher grain and fodder yield as compared to variety V2 (HQPM1) in all the years and also in pooled analysis. In pooled data, variety V1 (CO 6) produced 5842 and 9865 kg/ha grain and fodder yield, respectively. Application of every higher levels of fertilizer resulted in significantly higher grain and fodder yield during first and second year and pooled data as well. However, during third year, treatment F3 (180: 90: 00, N: P: K kg/ha) produced significantly higher grain and fodder yield over its lower levels of fertilizer i.e. F1 (120: 60: 00, N: P: K kg/ha) and F2 (150: 75: 00, N: P: K kg/ha) which were at par in their effect. The hybrid maize (CO-6) gave higher grain and fodder yield and net return, under spacing of 60 cm × 20 cm (83,333 plants per ha) and with fertilizer dose of 180:90:00 NPK/ha, when nitrogen applied in four splits i.e., at basal (20%), four leaf stage (30%), eight leaf stage (40%) and tasseling stage (10%) where as P2 O5 was applied as basal) during kharif season.

SUMMARY

Sorghum, green forage is well adapted to semiarid zones to feed livestock under saline regimes. In present study, structural fibrous fractions were evaluated in two sorghum genotypes viz. G-46 and S-713 under different salinity treatments (6, 8 dS/m) to quantify their values. Structural carbohydrate concentrations varied among genotypes and salinity levels. As the salinity level increased, there is reduction of all cell wall components. The cell wall constituents (NDF, ADF, HC, cellulose, lignin) exhibited upward trend with the plant maturity. The NDF content varied from 67.05 to 48.87 % with a relative mean value of 57.96% and at 95 DAS 59.65-76.02 %. Maximum ADF content was observed at maturity stage with a mean value of 40.82%. A significant difference was observed between different growth stages. For total lignin content, the reduction varies from 8.09-6.17 % with a mean value of 5.59 % at 35 DAS. With advancement of maturity, amount of lignin content increased with a mean value of 7.31%. Cellulose and hemicellulose content ranged from 38.09-27.07%, 29.04-24.97 % with mean values of 28.58 and 23.92 %, respectively. Overall, G-46 genotype performed better at all salinity levels and possessed maximum structural fiber fraction and might be a used in future breeding programmes to improve the fiber fractions.

SUMMARY

An experiment consisting of four plant density (45, 60, 75 and 90 kg/ha seed rate) and five fertilizer levels (0, 50, 75, 100 and 125 % RDF) was laid out in split plot design to find out the growth and yield of fodder maize (Zea mays L.) under varying plant density and nutrient management. Green fodder yield and dry matter yield was significantly higher in case of 60 kg/ha seed rate (543.32 and 121.03 q/ha, respectively) and 125% RDF application (637 and 140.98 q/ha, respectively). Significantly higher growth parameters viz., plant height (249.62 and 280.92 cm), leaf length (101.60 and 118.10 cm), leaf width (7.46 and 9.11 cm), number of leaves (14.44 and 17.13) etc. with seed rate (60kg/ha) and 125% RDF, respectively at harvest. At higher density beyond seed rate 60 kg/ha improvement in growth and yield was not significant. Nutrient uptake such as nitrogen (89.99 kg/ha) and phosphorus (39.85 kg/ha) significantly higher with 125% RDF application. Soil nitrogen and phosphorus status shown significant effect with respect varied seed rates and with respect to fertility levels, significantly higher soil N and P status were observed in 125% RDF application and 100 % RDF application was on par with it. Economics viz., gross returns (Rs. 86555.4 and 98738.1) and net returns (Rs. 47038.3 and 59453.1) of fodder maize crop with 90 kg/ha seed rate and 125% RDF, respectively were significantly higher when compared to rest of the seed rates and recommended fertilizer levels whereas higher B: C ratio was obtained in case of 60 kg/ha and 125 % RDF.

SUMMARY

A field experiment was conducted at Agronomy Research Area, CCS HAU Hisar to study the effect of integrated nutrient supply on productivity of pearl millet – wheat cropping system during 2015-16 and 2016-17 in randomized block design with treatments viz. RDF (Recommended dose of fertilizers) through inorganic source, RDF through inorganic source + Azotobactor + PSB, Recommended N through vermicompost, 75% recommended dose of nutrients through inorganic source + 25% N from vermicompost + Azotobactor + PSB, 50% recommended dose of nutrients through inorganic source + 50% N from vermicompost + Azotobactor + PSB, 25% recommended dose of nutrients through inorganic source + 75% N from vermicompost + Azotobactor + PSB both in pearlmillet and wheat crop. In pearlmillet as well as in wheat crop RDF + Azotobactor + PSB through inorganic source produced highest yield attributes and yield but it did not differ significantly from the treatment where RDF through inorganic source was applied. Application of 75% RDF through inorganic source + 25% N from vermicompost + Azotobactor + PSB produced significantly higher yield over 50% recommended dose of nutrients through inorganic source + 50% N from vermicompost + Azotobactor + PSB and 25% recommended dose of nutrients through inorganic source + 75% N from vermicompost + Azotobactor + PSB in respective crops.

SUMMARY

A field experiment was conducted on multi-cut fodder sorghum [Sorghum bicolor (L.) Moench] to determine the effect of nitrogen on yield, growth and proximate analysis at Punjab Agricultural University, Ludhiana, Punjab during the Kharif season 2018. The experiment was laid out in Randomized Complete Block Design (RCBD), using three replications. The results showed that increasing nitrogen dose increased all yield and growth attributes. All the parameters studied showed significant differences in first, second and third cuts. The genotype SPH 1840 due to higher GFY revealed significantly higher gross returns (Rs 93745), net returns (Rs 52913) and B:C ratio (2.29). Therefore, it could be inferred that 125% RDF for each cut found optimum and economical which recorded higher green forage, DMY, higher quality parameters, net returns and B : C ratio.

SUMMARY

Fifty diverse genotypes of barley were evaluated for different seed vigour parameters. Genetic diversity was assessed based on the observations for the different characters viz., seedling length (cm), seed density (g/cc), standard germination (%), seedling dry weight (mg), vigour index I & II, electrical conductivity (?S/cm/seed) and accelerated ageing test. All the genotypes were assembled into seven well defined clusters depending upon the similarity in the expression of their genetic divergence. Maximum number of genotypes were allocated in cluster III (13) followed by cluster II (12) and VII (6), while the cluster I was the smallest one with four genotypes only. Among the genotypes maximum distance within the same cluster was reported by cluster V (3.63) followed by cluster VII (3.37), cluster II (3.06) while the minimum intra-cluster distance was showed by the cluster IV (2.47). When diversity within clusters was studied it showed a range of 3.60 to 6.42. Cluster IV and V showed maximum inter-cluster distance of 6.42, followed by between cluster I and V (6.25). The lowest inter-cluster distance was observed between cluster II and III (3.60). Contribution of accelerated ageing (72 h) towards divergence was found maximum (37.80%) followed by seedling length (17.88%), electrical conductivity (17.63%), seedling dry weight (10.61%) whereas rest other traits contribute very little to divergence. Clusters III and V might be considered desirable for selecting genotypes which may be used as promising parents for hybridization. The genotypes which fall in these clusters were IBYT-HI-15, 2nd GSBYT-23 (2015), IBYT-HI-18, IBON-HI-67 (2015-16), AZAD, IBON-HI-13 (2015-16), DWRB 143, BH 13-26, 2nd GSBSN-60 (2015), INBON-15-16, MGL-62, 2nd GSBSN-15-35, IBYT-HI-20 and BH 959, RD 2909, MBGSN 145, 2nd GSBSN-28 (2015), BH 15-17 could be used in the hybridization programme for generation of wider variability.

SUMMARY

Sixteen genotypes of sorghum viz., UP Chari-4 G-48 HC-260 UP Chari-2 SSV-84 SSV- 84 Pusa Chari-6, Pant Chari-4, HC-136, Pant Chari-7, Pant Chari-3, UP Chari-1, Jawahar Chari-6, MP Chari, HC-171, UP Chari-3 and HJ-513 were studied for genetic variability, heritability and genetic advance for green fodder yield, days to 50% flowering, plant height, number of leaves per plant, stem girth, leaf length, leaf breadth, total soluble solids, leaf area, leaf stem ratio, protein content and green fodder yield. Analysis of variance showed highly significant differences among the parents and F1s for all the eleven traits. The parent’s vs hybrids revealed highly significant differences for all the observations. The F test indicated that the variance due to treatments were highly significant for all the attributes which indicated that the presence of substantial genetic variability in the present set of material. The highest values of genotypic and phenotypic coefficient of variation (more than 25%) were observed for plant height, stem girth, leaf stem ratio and green fodder yield per plant, suggested that there was a possibility of improvement of fodder yield through direct selection. High heritability coupled with high genetic advance as percent of mean was recorded for leaf length, days to 50% flowering, leaf breadth, leaf area, leaf stem ratio, protein content and green fodder yield per plant, indicating that these characters are governed by additive gene action. Direct selection of these attributes will be effective and profitably for yield improvement.

SUMMARY

Correlation and path analysis studies were conducted to determine the association among various seed yield and its component traits, and the direct and indirect contribution towards seed yield in 80 elite diverse fababean genotypes collected from different geographical areas among them 31 are exotic types and 49 are indigenous types. Seed yield per plant had a positive and highly significant genotypic and phenotypic correlations with days to 50% flowering(41.67 and 96.33), days to maturity(142 and 195.33), plant height, number of branches per plant, number of pods per plant, number of seeds per pod and 100 seed weight. Path coefficient analysis indicated that 100 seed weight had the highest direct and positive effect on seed yield per plant followed by number of pods per plant, number of seeds per pod, days to 50% flowering, number of branches per plant, plant height. So, from the combined results of correlation coefficient and path analysis, it may be concluded that 100 seed weight, branches per plant and number of pods per plant are the major yield contributing traits to be given selection pressure for improving yield.
