tailieunhanh - Economics and nutrient uptake by blackgram as influenced by secondary nutrients and zinc nutrition
To study the effect of foliar sprays of secondary nutrients and zinc nutrition on nutrient uptake and economics of blackgram, a field experiment was conducted during rabi, 2016- 17 on sandy loam soils of College Farm, Agricultural College, Mahanandi. The experiment comprised of eight treatments viz., control (T1), RDF (20-50-0 kg N-P2O5-K2O ha-1 ) (T2), RDF + foliar application of one per cent CaNO3 (T3), RDF + foliar application of one per cent MgNO3 (T4), RDF + foliar application of one per cent Sulphur (T5), RDF + foliar application of one per cent each of CaNO3, MgNO3 and Sulphur (T6), RDF + foliar application of ZnSO4 @ per cent (T7), T6 + foliar application of ZnSO4 @ per cent (T8). As per the results, foliar spray of secondary nutrients (Ca, Mg and Sulphur) and zinc at 25 and 45 DAS along with RDF (T8) recorded the higher values of dry matter, seed yield, haulm yield and nutrient uptake (secondary and zinc) while control treatment recorded the lower values among the treatments tested. | Economics and nutrient uptake by blackgram as influenced by secondary nutrients and zinc nutrition
