Livestock Productivity

Background: The improvement in livestock productivity may be possible by availing better quality fodder in adequate quantity to the dairy farmers. Zinc deficiency might be a major factor for lower quality fodder of cowpea. Methods: The experiment was laid out in factorial randomized block design; comprised of three cowpea cultivars viz., C-152, MFC-08-14 and MFC-09-1 and five zinc management practices viz., control; 10 kg ZnSO4 as basal; 20 kg ZnSO4 as basal; 0.5% ZnSO4 as foliar spray at 20 DAS; 0.5% ZnSO4 as foliar spray at 20 and 40 DAS. Result: Results revealed that C-152 showed significantly better quality in terms of higher dry matter, crude protein and total ash; and lower acid insoluble ash, neutral detergent fibre, acid detergent fibre and acid detergent lignin amongst all the three varieties. Though, remarkably higher ether extract was obtained with MFC-08-14. Among the zinc management practices, 20 kg ZnSO4 as basal (Zn3) and foliar application of 0.5% ZnSO4 at 20 and 40 DAS (Zn5) recorded significant improvement in fodder yield and quality traits of cowpea.

Fodder Yield

Background: Soils of North-Western Indo-Gangetic plains (IGP) are deficient in zinc content which may lead to lower forage yield of cowpea. Henceforth, the adequate supply of zinc either through soil or foliar spray and selection of suitable cultivar of cowpea could enhance the fodder productivity.Methods: A field experiment was laid out in factorial randomized block design during Kharif season, 2019 to assess the effect of different zinc management practices (control; 10 kg ZnSO4; 20 kg ZnSO4; 0.5% ZnSO4 foliar spray at 20 DAS; 0.5% ZnSO4 foliar spray at 20 and 40 DAS) on productivity and profitability of cowpea cultivars (C-152; MFC-08-14; MFC-09-1) and post-harvest fertility status of soil.Result: Cowpea cv. C-152 showed the highest growth attributes, green fodder yield, nutrient content as well as uptake and net returns. Among different zinc management practices, the application of 20 kg ZnSO4 as basal application or 0.5% ZnSO4 foliar spray at 20 and 40 DAS recorded significantly highest growth, green fodder yield, nutrient content as well as uptake and net returns. Significantly highest soil OC, available N, K and Zn were also noted under these treatments. It is inferred that cowpea cv. C-152 and application of either 20 kg ZnSO4 as basal or 0.5% ZnSO4 as foliar spray at 20 and 40 DAS were found the most productive and profitable approach and sustained the soil fertility status.

Background: Rapid expansion in population increased the global food demand. To meet this surge in demand for food and to ensure food and nutritional security addition of pulses in the cropping system is a visible alternative. Pulses intensifies cropping intensity, enhances health and fertility status of the soil and acts as a good source of dietary protein etc. However, due to a wide gap between the potential and actual yield of pulses in rainfed areas. Hence, identification and adoption of best management practices has become a pre-requisite. The present study was undertaken as the information available on foliar nutrition and different crop geometries on performance of different blackgram genotypes in rainfed condition is meagre. Methods: In this investigation conducted during kharif season of 2018 at Advanced Centre for Rainfed Agriculture, SKUAST-Jammu, Rakh Dhiansar. The experiment was laid out in factorial randomized block design with 3 factors and 3 replications. The factor-1 consisted of three blackgram cultivars (Uttara, PU-31 and Mash-114), factor 2 consisted of two crop geometries (30×10 cm and 45×10 cm) and factor-3 consisted of three foliar nutrition (Foliar spray of molybdenum as sodium molybdate @ 0.1% at 20 DAS, Foliar spray of 1.5% KCl at flowering and Foliar spray of molybdenum as sodium molybdate @ 0.1% at 20 DAS fb 1.5% KCl at flowering). Result: The results from the present investigation indicated that adoption of Mash-114 at 30×10 cm crop geometry, supplemented with foliar application of molybdenum as sodium molybdate @ 0.1% at 20 DAS fb 1.5% KCl at flowering could be a viable technological proposition under rainfed conditions of Jammu.

Aim: To investigate the effect of KCl and KClO3 as sources of potassium in aerobic rice with four types of split doses and two levels of foliar applications of potassium. Study Design: The experiment was laid out in Randomized Block Design with three replications. Place and Duration of Study: Pandit Jawaharlal Nehru College of Agriculture and Research Institute, Karaikal, Puducherry. Methodology : The rice variety PMK 4 was tested with two sources of potassium viz., Potassium chloride (KCl) and Potassium chlorate (KClO3), four types of split application viz., K control (S1), basal with no split (S2), two splits (S3) and three splits (S4) along with foliar application treatments viz., no foliar (F1) and foliar spray (F2). Results: The results of a field experiment revealed that the two splits of potassium increased the available P at the active tillering stage and harvest stage. Whereas, three splits increased the available P at panicle imitation and flowering stage. The KCl recorded higher available P at panicle initiation and harvest stages. The high phosphorus uptake was recorded in panicle initiation and flowering stages by three splits application of potassium. In grain also, especially the three splits through KClO3 recorded higher P uptake. Conclusion: The split applications tested in this investigation influenced the available phosphorus status in soil and phosphorus uptake. Increase in splits of potassium increased the P uptake. This result is in agreement with the results of Mitra et al. [1] who observed a significant increase in the uptake of N, P, K and S by increased level of K in Kharif rice.

A field investigation was carried out to study the influence of zinc and iron micronutrients on the performance of rainfed castor, in Professor Jayashankar Telangana State Agricultural University, Telangana state, India for three consecutive years during kharif 2011-12, 2012-13 and 2013-14. There were nine treatments viz., Control (no micronutrient application); soil application of FeSO4 @ 15 kg ha-1; soil application of FeSO4 @ 25 kg ha-1; soil application of ZnSO4 @ 15 kg ha-1; soil application of ZnSO4 @ 25 kg ha-1; foliar application of 0.5% FeSO4 at 50 DAS; foliar application of 0.5% FeSO4 at 50 and 90 DAS; foliar application of 0.5% ZnSO4 at 50 DAS; foliar application of 0.5% ZnSO4 at 50 and 90 DAS and tested in randomized block design with three replications. The foliar application of ZnSO4 (0.5%) twice at 50 and 90 DAS resulted in significantly higher seed yield (1698 kg ha-1), higher gross returns (Rs. 54344 ha-1), net returns (Rs. 33501 ha-1) and B:C ratio (2.60) over rest of the treatments. The seed yield improvement was to the tune of 54% over no micronutrient application. The uptake of major and micronutrients was greater when the crop received two sprays of ZnSO4 as compared to one spray of ZnSO4, two sprays of FeSO4 and soil application of either of the micronutrients. The castor bean crop responded to Zn better than Fe by producing 10.2% to 12.2% higher seed yield. Foliar spray was found superior to soil application in case of both the micronutrients.

A field experiment was conducted during Kharif 2018 at College Farm, College of Agriculture, PJTSAU to evaluate the effect of various sources of zinc and iron on dry matter yield, nutrient content and nutrient uptake of finger millet. This experiment was conducted with randomized block design with 14 treatments and replicated thrice.The results revealed that application of different Zinc and iron sources at different rates significantly influenced the dry matter yield, nutrient content and nutrient uptake of finger millet. The highest dry matter production was reported with T10 - application of  RDF (60:40:30 kg N,P2O5 and K2O kg ha-1)+ foliar application of FeSO4 @ 0.5% twice at 30 and 60 DAS at all the stages followed by T14- (RDF+ foliar application of Fe-humate @ 0.25% twice at 30 and 60 DAS). Nutrient content decreased and Nutrient uptake (Nitrogen, phosphorous, potassium, iron and zinc) by the crop steadily increased with advancement in age of the crop upto harvest. The treatment receiving (T10) RDF+ foliar spray of FeSO4 @ 0.5% twice at 30 and 60 DAS recorded the highest nutrient content and (N, P, K & Fe) uptake by crop at 30DAS, 60 DAS and at harvest followed by (T14) RDF+ foliar application of Fe-humate @ 0.25% twice at 30 and 60 DAS. While, the Zinc content and uptake by crop at 30 DAS, 60 DAS and at harvest was highest with the treatment receiving (T8) -RDF + Zn-Humate foliar spray @ 0.25% twice at 30 and 60 days after sowing and was followed by treatment T7-RDF + Zn-Humate soil application @ 42 Kg ha-1.
