Fertility Mapping and Balanced Fertilization for Sustaining Higher Productivity of the Pearl Millet-Wheat Cropping System in Agra District

The project aims at Improving pearl millet-wheat cropping system yield through balanced fertilization based on assessment of nutrient availability through a plant-based approach.

IPNI-2010-IND-506

Objectives . 1. Estimation of nutrient supplying capacity of Western UP soils through nutrient omission studies. 2. Estimation of nutrient requirement of wheat for unit yield from yield vs. uptake relations. 3. Village level fertility mapping using GIS and developing recommendations from maps for the subsequent crops. Work Plan . (A) Nutrient omission plot trials . Read more

Interpretive Summary

This project was initiated to assess the spatial variability in soil fertility in an intensively cultivated village of Uttar Pradesh. More than 100 soil samples were collected from Panwari village of Agra district to assess the spatial distribution of N, P, K, S, and Zn. Soil analysis revealed that available N content of the study area varied from 100 to 308 kg/ha, available P from 8 to 62 kg/ha, available K from 70 to 235 kg/ha, available S from 10 to 45 kg/ha and available Zn from 0.

Fertility Mapping and Balanced Fertilization for Sustaining Higher Productivity of Pearl Millet-Wheat Cropping System in Agra District, 2012 On-farm nutrient omission trials were conducted for the wheat crop in Agra district during the winter season. Treatments included ample application of NPKS (180 kg N, 90 kg P2O5, 100 kg K2O, and 40 kg S/ha), and subsequent omissions of N, P and K from the ample treatment.

Fertility Mapping and Balanced Fertilization for Sustaining Higher Productivity of Pearl Millet-Wheat Cropping System in Agra District, 2011 The project assessed a plant-based approach to develop SSNM strategies for pearl millet-wheat system. Omission plot trials in farmers’ fields helped assess the wheat nutrient response in the study area.

Fertility Mapping and Balanced Fertilization for Sustaining Higher Productivity of Pearl Millet-Wheat Cropping System in Agra District, 2010 The project evaluated a plant-based approach to develop site-specific nutrient management (SSNM) strategies for a wheat-pearl millet cropping system. Twenty on-farm trials on wheat were conducted at four selected sites in Agra, Uttar Pradesh during 2009-10.

Fertility Mapping and Balanced Fertilization for Sustaining Higher Productivity of Wheat in Agra District, 2009 The project evaluates a plant-based approach to site-specific nutrient management (SSNM) to manage farm nutrient variability. This approach uses a crop-based estimate of indigenous nutrient supply to determine the yield supported by the soil in absence of a limiting nutrient when all other nutrients are adequate.
