EFFECT OF GYPSUM AND MICRONUTRIENTS ON GROWTH AND YIELD ATTRIBUTES OF GROUNDNUTKowagana Kalpana, Umesha C. and Yeshamalla ShashmaAbstract The field experiment titled âEffect of gypsum and micronutrients on growth and yield attributes of Groundnutâ was conducted during Zaid, 2023 at Crop Research Farm, Department of Agronomy, Naini Agriculture Institute, SHUATS, Prayagraj, Uttar Pradesh. The experiment was laid out in Randomized Block Design with ten treatments which are replicated thrice. The treatments include 200 kg/ha gypsum + 5 kg/ha zinc, 200 kg/ha gypsum + 2.5 kg/ha boron, 200 kg/ha gypsum + 1 kg/ha molybdenum, 250 kg/ ha gypsum + 5 kg/ha zinc, 250 kg/ha gypsum + 2.5 kg/ha boron, 250 kg/ha gypsum + 1 kg/ha molybdenum, 300 kg/ha gypsum + 5 kg/ha zinc, 300 kg/ha gypsum + 2.5 kg/ha boron, 300 kg/ha gypsum + 1 kg/ha molybdenum and Control R.D.F 20:60:40 kg/ha NPK Results obtained that higher plant height (59.40 cm), plant dry weight (45.47 g/plant), root nodules/plant (91.67) and number of pods/plant (17.00), number of kernels/pod (1.87), seed yield (2.75 t/ha), haulm yield (3.72 t/ha), gross return (1,61,360.55 INR/ha), net returns (1,06,770.55 INR/ha) and B:C ratio was (1.95) were obtained by the application of 300 kg/ha gypsum in combination with 5 kg/ha Zinc in Treatment 7. |
