IMPACT OF FOLIAR SPRAY OF NPK AND GIBBERELLIC ACID ON QUALITY AND NUTRIENT UPTAKE OF CHICKPEA BASED INTERCROPPING SYSTEMKULDEEP KUMAR, S. KARMAKAR, ARVIND KUMAR SINGH, RAKESH KUMAR AND PIYUSH KUMAR BHARGAWAbstract An agronomic investigation was conducted during rabi season of 2019-20 and 2020-21 at Birsa Agricultural University, Ranchi. The experiment was laid out in split plot design with 3 replications. The treatments were comprised of 9 main plots viz., sole chickpea, sole wheat, sole linseed, sole safflower, sole mustard, chickpea + wheat (6:3), chickpea + linseed (6:2), chickpea + safflower (6:2), chickpea + mustard (6:2) and 3 sub-plots viz., foliar spray of water (control), 1% NPK (19:19:19) and GA3 (100 ppm). Results revealed that maximum grain yield (1273 kg/ha), protein and oil content (%) and total nitrogen uptake (93.56 kg/ha) were recorded with chickpea + mustard (6:2) and closly followed by chickpea + linseed. While total phosphorus uptake (23.25 kg/ha) was maximum in sole wheat and total potassium uptake was maximum in sole mustard (67.36 kg/ha). With regards to different foliar spray treatment, the maximum value for protein content and total phosphorus uptake by component crops was obtained under foliar spray of 1% NPK (19:19:19) at 45 days after sowing, whereas, grain yield, oil content and total nitrogen as well as potassium uptake were found maximum under foliar spray of GA3 (100 ppm) at 45 days after sowing during both the years of experimentation. |
