EFFECT OF FOLIAR SPRAYS OF HUMIC ACID THROUGH VERMICOMPOST WASH WITH NAA ON BIOCHEMICAL PARAMETERS AND YIELD OF WHEATSuvarna S. Gare, R.D. Deotale, P.P. Sawant and P.N. Bobade
An experiment to study the efficacy of foliar sprays of humic acid through vermicompost wash and NAA was done with eighteen different treatments and three replications in randomized block design. Two foliar sprays of humic acid through vermicompost wash and NAA were given at 45 and 60 DAS. Five concentrations of HA (300, 350, 400, 450 and 500 ppm) through VCW and two concentrations of NAA (25 and 50 ppm) individually and in combination were tested. Data were recorded for biochemical parameters such as leaf NPK content, seed protein content and yield parameters such as seed yield ha-1 and harvest index. The treatment T15 (350 ppm HA + 50 ppm NAA) followed by T14 (300 ppm HA + 50 ppm NAA) exhibited their significance over control and rest of the treatments under study in respect of above mentioned parameters.
