Agronomic, economic, social and environmental benefits of improved nutrient management practices in maize production systems under variable farm size, climate, soil fertility conditions and farmer resource endowment in Telangana, India.
A study was undertaken with the scientists of PJTSAU considering the following objectives. 1. To determine farmer typologies through implementation of rapid rural surveys in maize growing ecologies of Telangana. 2. To determine the impact of farmer resource availability on native soil fertility in variable maize growing environment 3. To determine the agronomic and economic impact of nutrient management in smallholder maize systems under contrasting tillage situations using ex-ante and on-farm assessment using Nutrient Expert 4. To provide options for maize intensification in different farmer typologies through Nutrient Expert based Site Specific Nutrient Management strategies 5. To train NARS, NAES, and industry partners in the application of NE to develop site-specific precision nutrient management recommendations suitable for all farm typologies in the study domain.

This study was aimed at understanding the maize-growing ecology in the state of Telangana, and to determine the benefits of improved nutrient management practices for maize production. The study covered two traditional (Karimnagar and Medak) and two emerging (Nizamabad and Mahabubnagar) maize-growing districts in the State. Read more
Interpretive Summary

The study covered two traditional (Karimnagar and Medak) and two emerging (Nizamabad and Mahabubnagar) maize-growing districts in the State.
The farm typology-based fertilizer recommendations allows a group of farmers belonging to a particular farm type to be eligible for the same recommendations for similar farm operations.
