Abstract


A field experiment was conducted on PKVU-15 blackgram during the Kharif season of 2013 at Pulse Research Unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola to study the effect of potassium on yield, quality, available nutrient status and its uptake of blackgram. Yield quality, nutrient status and its uptake of blackgram were significantly increased due to increased level of potassium fertilizer. RDF + 40 kg K2O ha-1 significantly improved the quality of seed, available nutrient status and nutrient uptake of blackgram over the application of RDF only. Treatment RDF + 40 kg K2O ha-1 was at par with RDF + 30 kg K2O ha-1 and RDF + 20 kg K2O ha-1, treatment RDF + Foliar spray of KCl 1.5 per cent (at flowering and 10-15 days after flowering) significantly improved the quality of blackgram and nutrient uptake over the application of RDF (20:40 N:P kg ha-1) only. This treatment was at par with soil applied RDF+ 20 kg K2O ha-1.
