Abstract: Field experiments on drip fertigation in blackgram were conducted at Department of Pulses, Tamil Nadu Agricultural University to assess the influence of fertigation of Water-Soluble Fertilizer (WSF) on the yield and economics of blackgram cultivation. Blackgram, being a short-duration pulse crop, is widely cultivated under rainfed conditions in submarginal land. It results in low productivity. Result revealed that 75 per cent yield increment was observed in blackgram with drip fertigation of 100 percent Recommended Dose of Fertilizer (RDF) through WSF compared to surface irrigation basal application of fertilizer. The same treatment also gave higher water use efficiency of 4.70 kg/ha mm, net monetary returns of ยน . 43132 /ha with benefit cost ratio (BCR) of 1.98 while higher nutrient use efficiency of 15.2 kg /kg of fertilizer had been recorded with drip fertigation of 75 % RDF through water soluble fertilizer. Hence, it might have concluded that drip fertigation of 100% RDF through WSF enhances the yield and profitability in blackgram.
