Global Maize Project in India: Ranchi, Jharkhand - Site Specific Nutrient Management in Maize-Wheat cropping system in Ranchi, Jharkhand

IPNI-2009-IND-GM22

The IPNI Global Maize Initiative is a coordinated research and technology transfer effort to narrow the gap between current and potential maize yields through improved crop and nutrient management while minimizing negative environmental impacts. Read more

Interpretive Summary

Ranchi is one of the two centers of the Global Maize Project in South Asia. The overall objective of the project is to improve the productivity of the maize-wheat cropping system over the farmers' existing fertilizer application practice (FFP). The experiment in Ranchi compared the effect of practicing ecological intensification (EI) over the FFP. Hybrid maize was grown during kharif 2014 and the crop was grown as rainfed crop.

To mitigate the gap in food production, a series of field experiments were carried out at Birsa Agricultural University. Investigations started in 2009-10 with a conventional variety of maize (var. Suwan composite 1) grown during kharif (June to October) and wheat (Var. K 9107) during rabi (November to March). Afterwards, the experiments were conducted with hybrid maize (variety-Pioneer 30V92) and wheat (variety-DBW-17) with higher potential yields.

The long-term evaluation of ecological intensification (EI) and farmers’ fertilization practices (FFP) continued in 2012-13 on a farm of Birsa Agricultural University, Ranchi, Jharkhand. The highest grain yields of maize (5. 2 t/ha) and wheat (3. 2 t/ha) were obtained with the NPK treatment (180:90:100 kg/ha for maize and 130:70:60 kg/ha for wheat). The NPK treatment recorded 74 % higher grain yield over FFP.

Three sets of field experiments were conducted at Birsa Agricultural University farm at Ranchi, Jharkhand on system evaluation of ecological intensification (EI), optimization of rate and time of N application, and omission plot studies with maize and wheat. The trials were carried out with hybrid maize grown during kharif (monsoon) and wheat during rabi (winter) seasons. Relevant soil properties were also measured.

Optimal nutrient management strategies for maize-wheat system were initiated in the Western Plateau Region of Jharkhand. Three experiments were conducted during 2011 with wheat (variety DBW 17) in rabi (December 2010 to April 2011) and maize (Pioneer 30V92) during kharif (June to October, 2011). Highest grain yield of maize (7. 0 t/ha) and wheat (4.

Productivity of maize and wheat grown in red and lateritic soils continues to be low due to poor nutrient use. Yield levels of maize can be increased 2 to 3 fold with optimal site-specific and balanced use of plant nutrients, which depends on the yield potential of the crop/varieties used and the inherent fertility of soil.

This project was initiated to optimize nutrient management for improved productivity within the maize-wheat cropping system. The working objective includes a quantitative estimation of the attainable yield potential of maize and wheat from a system perspective, estimation of the indigenous nutrient supplying capacity of soils, and using such information to develop a strategy of nutrient management to maximize system productivity.
