Abstract
An experiment was conducted during kharif season during the year 2015-16 to evaluate the studies on influence of multinutrient briquettes on movement of nitrogen, phosphorus, potassium and zinc in soil of Bt-cotton. The soil sampling was done at 15 cm away from cotton plant at 15 cm and 30 cm depth and at 30 cm away from cotton plant and at 15 cm and 30 cm depth. The results out came clearly showed that available nutrient status significantly decreased with increasing soil depths (15-15 cm, 15-30 cm, 30-15 cm and 30-30 cm). The maximum nitrogen was retained by treatment fertigation at all depths followed by application of briquette in root rhizoshere. The movement of nutrient P was observed at lower magnitude. It was non-significantly, however the P movement was maximum in briquettes and soluble fertilizers. The mobility rate of K is high if may leached faster than P and Zn but in present research mobility of K was reduced due to synergetic effect of slow release of N and Zn. The zinc content was more at 15 and 30 cm depth as compared to 30 cm away from the plant. The movement of zinc was found to be maximum in treatment receiving NPKZn briquette through drip irrigation. The DTPA zinc decreased with depth of sampling.
