Assessment of agronomic and economic benefits of fertilizer use in maize production systems under variable farm size, climate and soil fertility conditions in Karnataka of Peninsular India

IPNI-2014-IND-530

A study was initiated in Karnataka, to delineate farm typology based on biophysical and socio-economic aspects of farms and farmers, and use farm typology-based fertilizer recommendations to improve crop productivity and farmer profitability. Two emerging (Ballary and Koppal Taluks) and two established (Hadagali and Harpanahalli Taluks) maize-growing regions were identified and three villages were selected from each Taluk. Read more
