Assessing the Contribution of Nutrients to Yield of Hybrid Rice and Maize through Omission Plot Techniques in Bihar

IPNI-2013-IND-523

Overview Related

India is the second largest producer of rice in the world with production of 100 million tons in 2010-11. Rice occupies 44 Mha i. e. 22% of the total cropped area. However, at the current rate of population growth, in India the requirement of rice is estimated to be around 150 million tons within next fifty years. To make India self sufficient in rice, it is needed to improve the productivity to a greater extent, compared to the existing condition. Read more

Interpretive Summary

2016

The study was conducted at farmers' fields across two different districts (Samastipur and Muzaffarpur) of Bihar to refine fertilizer recommendations for rice and maize. The nine treatments included T1 (ample nitrogen (N), phosphorus (P), potassium (K), sulfur (S), and zinc (Zn)), T2 (-N), T3 (-P), T4 (-K), T5 (-S), T6 (-Zn), T7 (inbred variety under unfertilized check), T8 (inbred variety with ample NPKSZn), and T9 (hybrid variety under unfertilized check) within a randomized block.

This experiment was conducted at five on-farm locations in each of Samastipur and Muzaffarpur districts of Bihar as well as at one plot at the Research Farm, Rajendra Agricultural University, Pusa, Samastipur, Bihar, under a hybrid rice-maize cropping system during 2013-15. Hybrid rice was grown as a kharif (rainfed) crop while hybrid maize was grown during the rabi (winter) season.

This experiment was conducted at five on-farm locations each at Samastipur and Muzaffarpur Districts of Bihar and one plot at the University Research Farm, Rajendra Agricultural University in Pusa, Samastipur, Bihar, under hybrid rice-maize cropping system during 2013-14. Nine treatment combinations included: T1 (NPKSZn), T2 (-N), T3 (-P), T4 (-K), T5 (-S), T6 (-Zn), T7 (unfertilized local variety), T8 (local variety with ample NPKSZn), T9 (unfertilized hybrid variety). In hybrid rice (Var.

This study was designed to evaluate yeild response to nutrient additions in a hybrid rice-maize cropping system. Specific objectives of this study were to evaluate the soil supplying capacity of different nutrients (N, P, K, and Zn) under hybrid rice-maize cropping system and to determine the nutrient requirement of high yielding hybrid rice–hybrid maize cropping system.

Project Description

cover
Enhancing Indian Farmer Income with Balanced Nutrition of a Rice-Maize Rotation It has become increasingly common for farmers to grow rice, followed by maize each year in their fields. This rice-maize cropping system provides an option for farmers to diversify and improve their income compared to growing only rice. High-yielding maize removes more nutrients from the soil than rice or wheat. Current fertilization practices have led to an imbalanced and insufficient reservoir of many nutrients in the soil. Improper fertilization practices are leading to an overall decline in farm productivity. IPNI always recommends that farmers apply fertilizer nutrients according to the demand of the crop and apply nutrients in ways that minimize their loss and maximize their efficiency.
