SUMMARY

The imbalanced uses of inorganic fertilizers deteriorates soil health, declines the soil nutrient status, increased environmental pollution and also boost the cost of production of fodder crops. Application of organic sources alone to fulfill the demand of plant essential nutrient is also complex because an enormous amount of manure is required. Therefore, to sustain soil health and production, balanced use of fertilizer based on soil test crop correlations (STCR) approach with integration of organic manures is very essential. The integrated nutrient management (INM) system includes prudent application of organic, inorganic and biofertilizer in fodder crop to achieve optimal yields without causing harm to ecosystem. Application of integrated nutrient management practices improves availability of soil macro and micronutrient content in soil. The soil organic carbon, microbial biomass carbon,microbial population, urease, dehydrogenase and phosphatase activity were found highest under integrated treatments as compared to devoid of manures in fodder production. Hence it may be concluded that soil physical, chemical and biological properties are efficiently improved by adopting the integrated nutrient management practices.

SUMMARY

Drought stress is one of the most significant factors affecting agricultural lands and reducing crop production. Among the fodder crops, oats are largely grown for fodder and grain as they are a good source of fibres, proteins and minerals. Being high in energy, it provides high-quality feed for livestock. However, oats are susceptible to drought due to high rate of transpiration that may influences its morphological and physiological characteristics.In the present investigation, the plant growth-promoting bacteria i.e. Burkholderia seminalis, Azotobacter sp., Bacillus thaonhiensis, Stenotrophomonas maltophilia alone and in different combinations have been explored in augmenting the drought tolerance (5, 10, 15 and 20 % PEG) in oat seedlings via seed bio-priming with the liquid bacterial inoculant of aforesaid PGPB under in-vitro conditions.It was observed that the treatment T₁₁: B. seminalis+ S. maltophilia holds a great potential to mitigate drought stress by showing maximum improvement in the germination percentage, germination speed, mean germination time, shoot and root length as compared to the unprimed seeds. Moreover, they are organic, safe and cost-effective and maintains the productivity of the soil. Hence, the study encourages that bio- priming of oats seeds with PGPB can overrule the pernicious effect of water deficit to enhance the growth of oats.

SUMMARY

The present investigation was conducted to assess the different early and late season advance lines of pearl millet for yield and its attributing traits. The grain yield varied between 0.57 kg (MPMH-17) to 2.03 Kg (MH2474), while dry fodder yield ranged between 1.18 kg (GHB 905) to 4.92 Kg (MH2474). The days to 50 % flowering was observed lowest in HHB-67-I (44 days) and highest in MH-2566 (55 days), whereas lowest number of days to maturity taken by MH-2557 & MH-2555(69 days) and highest by MH-2570 (79 days). The 1000-seed weight was found minimum in MH-2553 (5.67 g) and maximum in PB-1705 (12.60 g). The genotypes MH 2474, MH 2559, MH 2562, MH 2560 and PB 1705 were found superior for grain yield and dry fodder yield. The correlation analysis revealed that GYNP was highly significant and positively correlated DFY and PHNP, whereas DM, PH & 1000-SW showed positive and significant correlation. DFY showed highly significant and positive correlation with DF, DM PH and PHNP while PD and 1000-SW had significantly positive correlation with DFY. Moreover, cluster analysis categorized twenty seven lines into three clusters indicating that these lines share common ancestry with similar objective. Cluster III consisted of twelve lines, cluster II had eight and remaining seven lines were grouped into cluster I. The highest inter-cluster distance was found between cluster I and cluster III (85.45) while highest intra-cluster distance was observed in cluster I (55.97). Henceforth, the advanced lines yielded higher must be validated under different agro-climatic regions and further quality improvement should be strengthened.

SUMMARY

The present study was carried out to assess genetic diversity for grain nutritional and agro- morphological traits among fifty genotypes (designated B and R-lines) of pearl millet. Significant genetic variation was identified for all the studied traits. Principal component analysis (PCA) was used to reduce large correlated data into three major principal components that report for maximum 65.04% of the variation. Among these PC1 contributes to the greatest variation (30%) followed by PC2 (19.95%.) and PC3 (15.08%). Maximum positive component loading towards PC1 was contributed by grain yield per plant (0.89), dry fodder yield per plant (0.85), number of productive tillers per plant (0.52) and towards PC2 was contributed by grain Ca content (0.84) and Mg (0.81) content. The biplot analysis revealed four groups with group IV having HR-108, HRI-1499, HR-1038, HR-1032 and GP-58 genotypes positively associated with grain Ca and Mg content and group I possessing GP-69, GP- 80, GP-70, HMC-283 and HMC-94-2 genotypes positively associated to grain yield

SUMMARY

Bacterial inoculants play a crucial role in enhancing agricultural productivity by facilitating nutrient uptake. However, the viability retention of these inoculants in liquid formulations remains a critical concern. The present study was carried out to investigate the viability retention of liquid bacterial inoculants (LBI) of Azotobacter sp., Sphingobacterium sp., Stenotrophomonas maltophilia and Burkholderia seminalis under different storage conditions. It was recorded that all the bacterial inoculants amended with 5mM trehalose remained viable upto a storage period of six months. A field experiment of forage pearl millet was conducted during kharif 2020 at Punjab Agricultural University, Ludhiana and Punjab Agricultural University, Regional Research Station, Bathinda involving combinations of LBI alongwith 100% recommended dose of fertilizer (RDF). It was observed that the treatment consisting of B. seminalis and S. maltophilia alongwith RDF yielded the highest green fodder and dry matter yield with percentage increase of 13.05 and 9.8 respectively, compared to the control. This research underscores the importance of optimizing storage conditions to maintain inoculant viability and highlights the pivotal role of viable bacterial populations in maximizing agricultural productivity and sustainability.

SUMMARY

A significant obstacle to cowpea [Vigna unguiculata (L.) Walp.] cultivation is weeds. There was an experiment was arranged in filed under all India coordinated research project – vegetable crops (AICRP-VC) on cowpea variety Kashi Kanchan to minimize the weed infestation during Kharif season. The seven different weed management strategies were tested in Randomized Block Design. The combined findings of three years showed that weed free check had the superior weed control efficiency, plant growth, development and pod production while the strategy having a very high investment cost in comparison to other weed management approaches. The black polythene mulch treatment outperformed other weed control methods in terms of weed flora reduction, weed control efficiency, crop growth, development and yield, albeit the treatment is also quite expensive. The PE application of oxyfluorfen @ 150 g ai/ha + one hand weeding at 35 – 45 DAS had the best weed control efficiency, pod yield and benefit cost ratio (1:2.07) followed by PE application of pendimethalin @ 1.0 kg ai/ha (1:2.06). Based on three years period results revealed that using plastic mulch is the most effective technique to control weeds than applying herbicides which had an economically cheap.

SUMMARY

The response of different fodder oat (Avena sativa L.) genotypes to varying nitrogen levels was studied in a field experiment at Pusa, Bihar. Ten genotypes (HFO-1009, HFO-1013, HFO-1003, JO-08-37, SKO-244, OL-1977, OL-1980, Kent, OS-6 and OS-403) were accommodated in the main plots of the split plot design and three nitrogen levels (80, 100, and 120 kg/ha) were used in sub-plots. Results revealed that OS-403 produced the maximum plant height (163.3 cm), green forage yield (516.5 q/ha) and production efficiency in term of green forage yield (5.07 q/ha/day) among the genotypes. However, the genotype OL-1980 produced the maximum dry matter yield and production efficiency in terms of dry matter yield and crude protein yield among the genotypes. The maximum gross (Rs. 103309/ha) and net returns (Rs. 72153/ha) and B:C ratio (3.32) was noted with OS-403 which was at par with OL-1980. The highest nitrogen level (120 kg N/ha) resulted in the highest green fodder (441.3 q/ha), dry matter (128.5 q/ha) and crude protein yield (11.8 q/ha) which significantly higher than rest of the N levels. N application enhanced the gross (Rs. 88267/ha) and net returns (Rs. 56850/ha) and B:C ratio (2.81) up to 120 kg/ha which was notably higher over other levels. The N fertilizer rate for maximum green forage yield and economical optimum N fertilizer rate for fodder oat was found to be 140.2 and 138.5 kg/ha, respectively.

SUMMARY

Bajra Napier Hybrid is a very popular perennial fodder grass among the dairy farmers of Kerala, as it is very well suited for the tropical condition. Kerala is a state with low per capita land availability. In this scenario, the study was conducted to assess the influence of different shade levels on the yield of promising varieties of Bajra Napier hybrid. Knowledge about the shade tolerance of different varieties of BN hybrid will help the farmers to cultivate this crop in coconut garden as well as the homesteads with different trees species, which offers a good opportunity to increase area under fodder production in the state. The experiment was laid out in split plot design with 12 treatment combinations in 3 replication, main plot treatmentswere different shade levels (open, 25% shade, 50% shade) and subplot treatments were different Bajra Napier hybrid varieties (Suguna, Susthira, CO-3, CO-5). It has been found that variety CO-5 under open (173.63 t/ha) and 50 per cent shade level obtained maximum green fodder yield (116.93 t/ha) and dry fodder yield. Variety Suguna under 25 per cent recorded maximum green fodder (101.85 t/ha) and dry fodder yield.

SUMMARY

The study was conducted on fresh and one year old seed lot of two varieties of oat viz., OS 6 and HFO 611 in the laboratory of Seed Science and Technology, CCS Haryana Agricultural University during 2022-23. The seeds of both the lots of these varieties were haloprimed with solutions of different concentrations (0.5, 1.0 and 1.5%) of various salts viz., NaCl, CaCl₂ and KNO₃ for 14 h and 24 h at 20oC temperature and dried back to original moisture content. The results revealed that all of the halo-priming treatments demonstrated an improvement in seed germination and vigour indices for both varieties. The extent of improvement was more in the old seed lot as compared to the fresh seed lot. Among the treatments, maximum enhancement in fresh seed lot was observed in seeds primed with CaCl₂ @ 1.5%, which was at par with NaCl @ 1.0%. However, for the old seed lot, CaCl₂ @1.0% gave better results. Halo priming for a duration of 24 hours resulted in more enhancements in seed quality as compared to 14 hour halo priming duration. No significant difference was observed with a 14-hour priming duration in the fresh seed lots of both varieties. Halo-priming the seeds with CaCl₂ @ 1.5% for 24 hours resulted in a 4.87% enhancement in seed germination as compared to the control for the fresh seed lot of variety HFO 611, whereas enhancement was 7.45% for OS 6 variety. Negative effect was observed on seed quality parameters when seeds were halo-primed for 14 h at higher concentrations (1.0 and 1.5%) of NaCl in old seed lots of both the varieties. In old seed lot of HFO 611 variety, germination reduced from 83.67% to 80.00% while in case of OS 6 variety it reduced from 77.33% to 74.00% when seeds were halo-primed with NaCl @ 1.5% for 14 h. It is concluded from the study that halo-priming is a beneficial technique for seed quality enhancement. Halo-priming of oat seeds with CaCl₂ @ 1.5% at 20oC for 24 hours should be used to enhance the seed quality.

SUMMARY

Field experiments on fodder sorghum were conducted during kharif season of 2022 and 2023 at Research farm of CCS HAU Regional Research Station, Rohtak situated at Samargopalpur to evaluate the bio-fortification of fodder sorghum for enhancing zinc and iron content. The field experiment was conducted in factorial RBD design with four zinc levels viz. No ZnSO₄, 0.5% ZnSO₄ foliar spray at 30 DAS, 0.5% ZnSO₄ foliar spray at 45 DAS and 0.5% ZnSO₄ foliar spray at 30 and 45 DAS and four iron levels viz. No FeSO₄, 0.5% FeSO₄ foliar spray at 30 DAS,0.5% FeSO₄ foliar spray at 45 DAS and 0.5% FeSO₄ foliar spray at 30 and 45 DAS in three replications. The fodder sorghum variety HJ 513 was sown on 25 June 2022 and 23 June 2023 respectively. The soil of the experimental field was low in organic matter content and available nitrogen and medium in available phosphorus and potassium. The recommended dose of fertilizer was applied as per package of practices of CCS HAU, Hisar. The half dose of nitrogen and full dose of phosphorus was applied at the time of sowing as basal dose and remaining half dose of nitrogen was top dressed at crop knee high stage. Both zinc and iron were applied as foliar sprayed as per the treatments. The crop was harvested at 50 % flowering stage because it’s a stage where the plant has accumulated a significant amount of biomass and nutrients, making it optimal for fodder production. Results revealed that foliar sprays of zinc and iron have several positive effects on growth and yield of fodder sorghum crops. The mean increases with application of two foliar sprays of 0.5 % ZnSO₄ with 2.5 % urea at 30 and 45 DAS were to the tune of 20.4 % in green fodder yield over control. Whereas, 14.4 % and 11.7 % higher green fodder yield of sorghum was recorded with foliar spray of 0.5% ZnSO₄ at 30 DAS and 0.5% ZnSO₄ at 45 DAS, respectively. Similarly, foliar spray of 0.5 % FeSO₄ at 30 and 45 DAS resulted in 19.8 %, 14.4 % and 13.4 % higher green fodder yield of sorghum over control, foliar spray of 0.5% FeSO₄ at 30 DAS and foliar spray of 0.5% FeSO₄ at 45 DAS, respectively. Two foliar sprays of 0.5% FeSO₄ (30 and 45 DAS) resulted in highest B: C (1.92) followed by one foliar spray of 0.5% FeSO₄ at 45 DAS (1.72) and one foliar spray of 0.5% FeSO₄ at 30 DAS (1.74). Maximum crude protein (11.97 and 11.70 %) was recorded when two foliar spray of 0.5% ZnSO₄ and FeSO₄ were done (30 and 45 DAS) that was statistically similar with one spray of 0.5% ZnSO₄ and FeSO₄ at 30 and 45 DAS both and minimum crude protein (9.93 and 10.11 %) was obtained in control treatment.

SUMMARY

The experiment was carried out at the Department of Agronomy, N. M. College of Agriculture, Navsari Agricultural University, Navsari (Gujarat) during the summer seasons of 2020 to 2022. The treatment consists of three levels of organics (Control, FYM 5.0 t/ha and Bio compost 5.0 t/ha) and three levels of nitrogen viz., 75 kg N/ha, 100 kg N/ha and 125 kg N/ha in Randomized Block Design with factorial concept. The common application of Biofertilizers, Azotobacter + PSB used as seed treatment @10 ml/kg seed each. The result of three year experimentation revealed that application of Bio compost 5.0 t/ha produced higher plant height, leaf: stem ratio, crude protein content, green fodder yield, dry fodder yield and maximum profit as compared to FYM. The content of N was found significant with application of Bio compost where as P₂O₅ and K₂O found non significant. Nutrient uptake also significantly influenced and higher with use of the Bio compost 5.0 t/ha. The major nutrients (N, P₂O₅ and K₂O) in soil stated the positive effect by application of Bio compost 5.0 t/ha. In case of nitrogen levels, application of 125 kg/ha produced higher plant height, number of leaves per plant, leaf: stem ratio, crude protein, green fodder and dry fodder yield and ultimately maximum net return. The uptake of N, P₂O₅ and K₂O were also higher under this treatment. The interaction was also found significant with respect to quality parameters crude fiber and leaf stem ratio. The lower CF observed under N₃O₁ and N₃O₂. In case of L:S ratio the higher L:S ratio observed under N₃O₂ and N₂O₂.
