Effect of fertility levels and stress mitigating chemicals on nutrient uptake, yield and quality of mungbean [Vigna radiata (L.) Wilczek] under loamy sand soil of Rajasthan

A field experiment was conducted during kharif season of 2017 on loamy sand soil to study the Effect of Fertility Levels and Stress Mitigating Chemicals on productivity of Mungbean [Vigna radiata (L.) Wilczek]. The experiment consisted of four fertility levels [control (F0), 50% RDF (F1), 75% RDF (F2), 100% RDF (F3) ] and four stress mitigating chemicals [control (S0), SA @ 75 ppm at flower initiation and 7 days after first spray (S1), SA@75 ppm + 2% Urea at flower initiation (S2) and Thiourea @ 500 ppm (S3)]. Results indicated that the application of 75% RDF being at par with 100% RDF, significantly increased the phosphorus concentration and total P- uptake, total K- uptake. However, in respect of N concentration in seed and straw and its uptake and protein content in seed, seed (1077 kg ha-1 ), straw (2279 kg ha-1 ) and biological yield (3356 kg ha-1 ), 100% RDF excelled over all other treatments. Results further revealed that among stress mitigating chemicals 500 ppm thiourea remaining at par with SA + 2% Urea significantly higher seed (1048 kg ha-1 ), straw (2276 kg ha-1 ) and biological yield (3324 kg ha-1 ), protein content, nitrogen and phosphorus concentration and their uptake K- uptake of mungbean over SA and control. | Effect of fertility levels and stress mitigating chemicals on nutrient uptake, yield and quality of mungbean [Vigna radiata (L.)
