Abstract
A field experiment was conducted at Achalvadi village, located at Harur block of Dharmapuri district to study the effect of foliar nutrients on the growth, yield and economics of blackgram. The experiment consisted of ten treatments. The experimental plots were laid out in randomized block design with three replications. The treatments consisted of, T1 – Control, T2 – RDF (44:22:0 kg of NPK ha-1) + EFYM @ 750 kg ha-1 , T3 – RDF + EFYM @ 750 kg ha-1 + Foliar application of 2% urea twice at 30 and 45 DAS, T4 - RDF + EFYM @ 750 kg ha-1 + Foliar application of 2% DAP twice at 30 and 45 DAS, T5 - RDF + EFYM @ 750 kg ha-1 + Foliar application of 1% KCl twice at 30 and 45 DAS, T6 - RDF + EFYM @ 750 kg ha-1 + Foliar application of 3% Panchagavya twice at 30 and 45 DAS, T7 - RDF + EFYM @ 750 kg ha-1 + Foliar application of 2% urea at 30 DAS+ Foliar application of Silixol plus @ 1 ml/litre @ 45 DAS , T8 - RDF + EFYM @ 750 kg ha-1 + Foliar application of 2% DAP at 30 DAS + Foliar application of Silixol plus @ 1 ml/litre @ 45 DAS, T9 - RDF + EFYM @ 750 kg ha-1 + Foliar application of 1% KCl at 30 DAS + Foliar application of Silixol plus @ 1 ml/litre @ 45 DAS, T10 - RDF + EFYM @ 750 kg ha-1 + Foliar application of 3% Panchagavya at 30 DAS + Foliar application of Silixol plus @ 1 ml/litre @ 45 DAS. Among the various treatments tried, application of RDF + EFYM @ 750 kg ha-1 + Foliar application of 2% DAP at 30 DAS + Foliar application of Silixol plus @ 1 ml/litre @ 45 DAS (T8) recorded the maximum growth parameters viz. plant height (35.64 and 40.78 cm at 45 DAS and harvest stages respectively), number of branches plant-1 (7.86), leaf area index (5.72) and dry matter production (14.69 g plant-1), yield attributes viz. number of pods plant-1 (14.38), number of seeds pod-1 (7.27), yield (1247 and 1975 kg ha-1 of seed and haulm yield respectively) and economics (Rs. 86043, Rs. 57195 and 2.98 of gross income, net income and B:C ratio respectively) of the crop. This treatment was followed by RDF + EFYM @ 750 kg ha-1 + Foliar application of 2% DAP twice at 30 and 45 DAS (T4). The lower values of growth parameters, yield attributes, yield and economics were recorded under the control treatment (T1).
