Abstract/ Executive Summary:

Soil with low moisture produced higher crop biomass, although nutrient content (NPK) in different plant parts was generally low under such condition. Nutrient absorption of mungbean was not affected by planting methods in low moisture regime. When the crop was dibbled it absorbed more N and P than other planting methods in high moisture regime. Crop in tilled soil had more K content than in untilled soil. Total nutrient uptake was higher from low moisture regime than in high moisture regime. The utilization efficiency of N, P and K followed the similar pattern of nutrient uptake, and was higher in broadcast method of sowing under low moisture condition.

Keywords: Mungbean, Moisture regime, Planting, Nutrient uptake

Location: BARI, Joydebpur , Gazipur

Start Date: 01-01-1992

End Date: 30-06-1992

Program Area: Crop-Soil-Water Management

Commodity: Mungbean

Objectives:

To study the different planting methods of mungbean under varying moisture regimes

Methodology:

Six Planting methods viz. (1) relay (seeds sown five days before rice harvest), (2) broadcast (seeds sown on the day following rice harvest), (3) dibble 1 (seeding done on the day following rice harvest with a dibble stick) , (4) dibble 2 (dibbling done along with conventional tillage ( 5) furrow (seeds placed in 10 cm deep furrows made by hand tool) and (6) conventional tillage (one rotovation followed by two harrowings} were evaluated on low and high soil moisture regimes.

Achievement/Findings:

Crop in tilled soil had more K content than in untilled soil. Total nutrient uptake was higher from low moisture regime than in high moisture regime. The utilization efficiency of N, P and K followed the similar pattern of nutrient uptake, and was higher in broadcast method of sowing under low moisture condition.
