Abstract/ Executive Summary:

A pot experiment was carried out with four Boro rice varieties to observe grain growth and yield performance under different soil moisture regimes. Moisture levels viz., 5 cm standing water, 100% field capacity (FC) and 80% FC were maintained during booting, flowering and tillering to maturity stages separately for yield performance. Moisture levels viz., 100, 80 and 30% FC were also maintained from panicle emergence to maturity for grain growth pattern. Plant height, tiller number, panicle number, panicle length, number of filled grains per panicle, 1000-grain weight, total dry matter, yield and harvest index were decreased with the less soil moisture. Binadhan-5 produced highest yield, more tillers and panicles per plant, highest 1000-grain weight and TDM and medium HI under different soil moisture regimes. Binadhan-6 showed better yield but the highest TDM and medium HI. Iratom-24 showed medium yield, TDM and the shortest panicle. BRRI dhan29 showed the highest HI but it produced lower grain yield under different soil moisture regimes. Binadhan-5 and Binadhan-6 may be used for developing suitable varieties in breeding program for different soil moisture regimes in Bangladesh.

Start Date: 20-12-2000

End Date: 15-04-2001

Program Area: Crop-Soil-Water Management

Commodity: Rice

Objectives:

The objective of the study was to find out optimum soil moisture at reproductive stages for better yield in boro rice.

Methodology:

A pot experiment was conducted with four rice varieties viz., Binadhan-5, Binadhan-6, lratom-24 and BRRI dhan29 at Crop Physiology Division, Bangladesh Institute of Nuclear Agriculture, Mymensingh during Boro season of 2000-2001. Rice was grown in plastic pots. Each pot contained 8 kg soils collected from BINA farm. The soil was sandy loam in texture having pH 6.7. Three seedlings of 30-day old were transplanted in each pot on December 20, 2000. Urea 576 mg. TSP 560 mg, MP 320 mg and Gypsum 66 mg per pot were applied following 90-84-60-5 kg of N-P₂O₅- K₂O-S fertilizer ha^-1respectively. The pot experiment was arranged in 2 factors completely randomized design with 3 replicated pots. The total pot grown plants were divided into 2 groups. Three water regime treatments viz., 5cm standing water, 100% field capacity (FC) and 80% FC were imposed at booting and flowering stage for all varieties and continued till maturity in one group for morphological studies. Those treatments were also imposed in another group from tillering to maturity for yield and yield attributes. Three water regimes viz., 100% field capacity (FC) 80% FC and 30% FC were imposed at flowering stage for all varieties and continued till maturity for grain growth studies. After fertilization 20 grains from 3 selected panicles were harvested at 3 days’ intervals. Amount of water in pot soil at 100% FC was determined and 100% and 80% of measured level was maintained for 100% and 80% FC, respectively. Amount of water to be added to maintain the desired water level was measured by weighing the pots at alternate days. The rice plants were harvested at maturity for measurement of yield and yield components. The data were analyzed statistically following two and three factor experimental design of CRD by MSTAT computer packages (Freed 1992).

Achievement/Findings:

Yield and yield attributes of Boro rice varieties were affected by soil moisture 80% FC at booting and flowering stages. So, 100% FC should be maintained at these two stages to obtain good yield in Boro rice.
