ABSTRACT
The study was conducted on the influence of precision nutrient management on growth and yield of groundnut at central dry zone of Karnataka at Devarkotta, ZAHRS, Babbur farm, Hiriyur, Chitradurga, Karnataka during 2013-14. The study was conducted in farmers fields with 50 x 50 m grids have been delineated using Geospatial technology and also DGPS locations have been used for each grid to map the field variability. The soil samples from 0-15 cm were collected and analysed for different major and micro nutrients in all the selected 139 grids. Among different practices, precision nutrient management recorded significantly higher pod yield (12.75 q/ha), plant height (28.8 cm), number of branches (10.3), leaf area (989.6 cm2/plant), number of pods per plant (20.2) and pod weight (13.29 g) in groundnut over recommended practice and farmer' practice respectively.
Key words :
Growth & yield attributes, Groundnut, Number of pods, PFP, Precision nutrient management, Pod yield.
