dc.description.abstractA field experiment entitled “Response of greengram (Vigna radiata L.) to foliar nutrients and biostimulants” was carriedout during kharif, 2018 on sandy loam soil of dryland farm of S. V. Agricultural college, Tirupati, Acharya N.G. Ranga Agricultural University. The experiment was laidout in randomized block design and replicated thrice. There were nine treatments viz., No spray (Control) (T1), Urea @ 2 % spray (T2), 19:19:19 @ 0. 5% spray (T3), Humic acid @ 0.1 % spray (T4), Seaweed extract @ 2 % spray (T5), Urea @ 2 % + humic acid @ 0.1 % spray (T6), 19:19:19 @ 0.5 % + humic acid @ 0.1 % spray (T7), Urea @ 2 % + seaweed extract @ 2 % spray (T8) and 19:19:19 @ 0.5 % + seaweed extract @ 2 % spray (T9). The test variety of greengram was Yadadri (WGG-42). Various foliar nutrients and biostimulants exerted significant influence on the growth parameters, yield attributes, yield, economic returns, quality and post-harvest soil fertility status. Among the foliar nutrients and biostimulants tried, application of 19:19:19 @ 0.5 % + seaweed extract @ 2 % spray at 30 and 45 DAS recorded the tallest plants, maximum leaf area index and higher drymatter production of greengram, at all the crop growth stages except at 20 DAS. Application of 19:19:19 @ 0.5 % + humic acid @ 0.1 % spray proved as the next best xv treatment. Growth characters were found to be at their lowest in plots which have not received any foliar sprays. Yield attributes viz., number of branches plant-1, number of pods branch-1, number of pods plant-1, number of seeds pod-1, length of pod and hundred seed weight were found to be higher with 19:19:19 @ 0.5 % + seaweed extract @ 2 % spray while these parameters were found to be at their lowest in the plots which have not received any of the foliar sprays. Among the various foliar sprays tried, application of 19:19:19 @ 0.5 % + seaweed extract @ 2% spray resulted in the higher seed yield, haulm yield and it was closely followed by 19:19:19 @ 0.5 % + humic acid @ 0.1 % spray. The lowest seed yield and haulm yield were produced in plots which have not received any of the foliar sprays. Harvest index was not influenced significantly by various foliar nutrients and biostimulants. Protein content of greengram was significantly highest with foliar sprays of 19:19:19 @ 0.5 % + seaweed extract @ 2 % while, it was lowest with control i.e. without any foliar spray. The highest post-harvest soil available nitrogen was registered with 19:19:19 @ 0.5 % + seaweed extract @ 2 % spray while it was lowest in no spray plot. Other foliar sprays failed to exert any significant influence on soil available phosphorus and potassium status. Economic analysis revealed that the highest gross returns, net returns and benefit-cost ratio were recorded with 19:19:19 @ 0.5 % + seaweed extract @ 2 % spray (T9) which was superior to the rest of the treatments, while all of them were lowest with no spray (T1). In conclusion, the investigation revealed that foliar application of 19:19:19 @ 0.5 % + seaweed extract @ 2 % spray at 30 and 45 DAS proved to be promising nutrient management practice for obtaining higher yield, quality and economic returns of greengram.en_US
