Abstract/ Executive Summary:

A field experiment was conducted at the sub-station farm of Bangladesh Institute of Nuclear Agriculture (BINA), Satkhira, to observe the effect of Farm yard manure (FYM), Gypsum and Nitrogen levels on growth and yield of rice (cv. Binadhan-8). The experiment was laid out in a RCBD split-plot design with three replications. Treatments consisted of five FYM and Gypsum combinations in main plot, which were S₀: Control, S₁: FYM 5 tha^-1 + Gypsum 140 kgha^-1, S₂: FYM 5 tha^-1 + Gypsum 210 kgha^-1, S₃: Gypsum 210 kgha^-1 and S₄: FYM 5 tha^-1. Four nitrogen levels were assigned in sub-plots viz. N₁: 50 kg Nha^-1, N₂: 75 kg Nha^-1, N₃: 100 kg Nha^-1 and N₄: 125 kg Nha^-1. The study revealed that different FYM and Gypsum combinations along with different N levels have significant effect on growth and yield of rice. Mean effect of FYM and Gypsum combinations found the highest for grain (3.69 tha^-1) and straw (6.60 tha^-1) yield where plot received FYM @ 5 tha^-1 +Gypsum 210 kgha^-1. Considering the mean effect of different N levels, when the plant received 125 kg Nha^-1 then the maximum grain and straw yield of rice were observed as 3.81 and 6.91tha^-1, respectively. Due to the interaction effect of both FYM and Gypsum combinations and N levels, the maximum grain yield of rice was found as 4.39 tha^-1under the treatment combination of S₂N₄, i.e., FYM @ 5 tha^-1and Gypsum 210 kgha^-1 along with 125 kg Nha^-1.

Keywords: FYM, Nitrogen, Gypsum, Rice and Saline soil

Location: BINA substation farm, Benorpota, Satkhira

Start Date: 00-01-2013

End Date: 00-04-2013

Program Area: Crop-Soil-Water Management

Commodity: Rice, Manures, Fertilizer

Objectives:

To observe the effect of different FYM and Gypsum combinations with nitrogen levels and their interaction on the growth and yield of BINA released rice variety (cv. Binadhan-8) under saline soil.

Methodology:

The experiment was conducted at BINA substation farm, Benorpota, Satkhira (22^o45’N latitude and 89^o4’6E longitude) during the Boro season of 2013 (January to April, 2013). The land belongs to AEZ 13, Ganges Tidal Floodplain and the soil was silty clay in texture, having pH 8.0, total N 0.10%, available P 7.0 mg kg^-1, available K 0.082 meq/100g and available S 13.5 mg kg^-1. The salinity value of initial soil is 6.2 dsm^-1_; this is considered as very slight saline to slight saline soil. The experiment was laid out in a split-plot design with three replications, where five FYM and Gypsum combination treatments were assigned in main plots viz. S₀: Control, S₁: FYM 5 tha^-1 + Gypsum-140 kgha^-1, S₂: FYM 5 tha^-1 + Gypsum 210 kgha^-1, S₃: Gypsum 210 kgha^-1 and S₄: FYM 5 tha^-1 and nitrogen levels were assigned in sub-plots viz. N₁: 50 kg Nha^-1, N₂: 75 kg Nha^-1, N₃: 100 kg Nha^-1 and N₄: 125 kg Nha^-1. The test rice variety was Binadhan-8, which was released from BINA as a salt tolerant Boro rice which can tolerate 10 dsm^-1 of EC value. Total amount of TSP, MoP and Gypsum were added as broadcast during final land preparation. N fertilizer was applied as urea in three equal splits as i) at three days of transplanting, ii) 28 days of transplanting (tillering stage) and iii) 50 days of transplanting (panicle initiation stage). Intercultural operations were done as when required. The yield parameters - plant height, panicle length, number of plant hill^-1, number of grains panicle^-1 and grain and straw yield data were recorded at maturity during rice harvest. The analysis of variance for various crop characters was done following the F-statistics. Mean comparisons of the treatments were made by Duncan Multiple Range Test (DMRT) test.

Achievement/Findings:

FYM and Gypsum combinations along with different N levels have significant effect on growth and yield of rice in saline area of Satkhira district, Bangladesh. The mean effect of different FYM and Gypsum combinations the highest grain (3.69 tha^-1) and straw (6.60 tha^-1) yield were obtained where the plot received FYM @5 tha^-1 with Gypsum 210 kgha^-1. Mean effect of different N levels, when the plant received 125 kg Nha^-1 then the maximum grain and straw yield of rice were observed as 3.81 and 6.91 tha^-1, respectively. Due to the interaction effect of both FYM and Gypsum combinations and N levels, the maximum grain yield of rice was found as 4.39 tha^-1 under the treatment combination of S₂N₄ where plot received FYM @5 tha^-1 with Gypsum 210 kgha^-1 combined with 125 kg Nha^-1.
