Abstract/ Executive Summary:

Maize is the highest yielder grain crop it has multiple uses such as human food, animal feed and fodder. It is consumed as a staple food in the central and South American and some African countries. Its cultivation in Bangladesh has been expanded rapidly during recent years mainly because of growing demand in poultry feed industries. Though maize has high yield potential, high nutrient uptake and imbalanced fertilizer use limits its expansion and decrease yield. In recent past, plaeuting or in some cases decrease in maize yield have been reported in Bangladesh. In this study, maize crop residue incorporation did not affect the yield of DS Aman.

Keywords: Maize, Crop residue incorporation, Productivity, Direct seeded Aman rice, Cropping pattern

Location: BRRI farm, Gazipur

Start Date: 01-07-2007

End Date: 30-06-2008

Program Area: Crop-Soil-Water Management

Commodity: Manures

Objectives:

To develop management options for sustaining productivity of direct seeded (DS) Aman based maize cropping system under irrigated ecosystem.

Methodology:

The experiment was initiated at East byed, BRRI Experimental Farm, Gazipur during 2006-07 in Boro season. The experiment was laid out in the Randomized Complete Block Design (RCBD) with 3 replications. BRRI dhan33 ( fertizer dose:150-97-71-52-7.5 kg/ha urea-TSP-MP-Gypsum-Zinc sulphate, respectively) was grown by direct seeding during Aman season with five treatments which were i) without maize crop residue incorporation, ii) 100% maize crop residue incorporation, iii) 75% maize crop residue incorporation, iv) 50% maize crop residue incorporation and v) 25% maize crop residue incorporation. BRRI recommended fertilizer was also used along maize crop residue. In Rabi season, BARI Hybrid Maize5 was used and BARI recommended fertilizer ( 550-260-220-260-15-7 kg/ha urea-TSP-MP-Gypsum-Zinc sulphate-Boric acid, respectively) were followed. After maize crop harvest, crop residues were incorporated.

Achievement/Findings:

There was no significant difference in maize yield and yield contributing characters among the treatments. Maximum yield was found in T₁(6.30 t/ha). Similar trends for Aman rice was observed and the highest yield of 4.15 t/ha was obtained in T₄.
