Assessment of Agronomic and Economic Benefits of Fertilizer Use in Maize Production Systems under Variable Farm Size, Climate and Soil Fertility Conditions in Odisha

IPNI-2013-IND-527

Maize, though gaining popularity among the farmers of Odisha, the full benefits of growing maize were not achieved due to improper input management, particularly nutrients. Small farm size, variable farmer management practices, lack of fertilizer recommendations tailoring to farm size considering farmer resources were some of the constraints. Read more

Interpretive Summary

The current study involved delineation of farm typology based on the information collected through survey on different socio-economic, bio-physical and resource availability aspects of farmers. The study considered two established (Bolangir and Keonjhar) and two emerging (Cuttack and Baleswar) maize-growing districts of Odisha. In each district, three farm types were identified based on the resource endowment of farmers and each farm type was assigned with an yield target.

The current investigations studied the influence of farmer resources and management practices on maize productivity in Odisha. Farmer typologies were categorized based on the information gathered on socio-economic and bio-physical parameters collected through the rapid rural survey. The identified typologies were further used to provide farmer resource based precise nutrient recommendations.

Maize is gaining popularity among the farmers of Odisha, but productivity is very low in the state mainly due to improper input management, particularly nutrients. Small farm size, variable farmer management practices, lack of appropriate fertilizer recommendations tailored to farm size with consideration of small-farmer resources are some of the other constraints holding back the attainment of potential maize yields in the state.
