Abstract/ Executive Summary:

An experiment was carried out at the Research Field of Crop Physiology and Ecology Department, Hajee Mohammad Danesh Science and Technology University, Dinajpur from July to November 2018. The study evaluated the effects of poultry litter based composts on morpho-physiological, yield and yield contributing characters of transplanted aman rice (var.Binadhan-7, BRRI dhan56, BRRI dhan66) and soil fertility. The experiment was laid out in a two factorial complete randomized design (CRD) with three replications. Factor A included three varieties (Binadhan-7: V₁, BRRI dhan56: V₂, and BRRI dhan66: V₃) and factor B comprised of three fertilization levels viz. control (inorganic)-F₁, poultry litter based compost 20 ton ha^-1: F₂, and 30 ton ha^-1: F₃. The performances of plant growth parameters such as plant height, tiller number, leaf number, leaf area, SPAD value, as well as yield and yield contributing parameters, and soil chemical properties were measured. Varieties and fertilizer levels significantly influenced most of the morpho- physiological traits and yield and yield contributing characters. The tallest plant was recorded from V₂ variety (BRRI dhan56). The highest leaf number hill^-1 (80.89 at 30 DAT) was recorded from V₃ (BRRI dhan66). The highest number of tiller was produced by the interaction of compost F₂ (20 t ha^-1) with V₁ (Binadhan-7). The highest effective tiller number (13.67) hill^-1was recorded from F₂ (compost 20 t ha^-1) with F₁ (Binadhan-7) at maturity. The longest panicle (24.16 cm) was found in F₁V₁ (inorganic with Binadhan-7) treatment. The highest 1000-grain weight (23.57 g) was recorded from F₃V₃ treatment (compost-30 t ha^-1 with BRRI dhan66). The maximum harvest index was recorded from F₁ (inorganic) with BRRI dhan66. Soil fertility status increased with higher dose poultry litter based compost (30 t ha^-1).

End Date: 00-11-2018

Program Area: Crop-Soil-Water Management

Commodity: Manures, Soil fertility, Rice

Objectives:

To develop a suitable integrated dose of poultry litter based compost for rice (var.Binadhan-7, BRRI dhan56, BRRI dhan66) and to observe the effects of different levels of inorganic fertilizers and poultry litter based compost on the yield and yield components of rice (var. Binadhan-7, BRRI dhan56, BRRI dhan66) as well as soil fertility.

Methodology:

The experiment was conducted to find out the effect of fertilizer and manure on the yield of T. aman rice. It was conducted during the period from July to November 2018 in the wet season. The location of the site is Crop Physiology and Ecology Research Field, Hajee Mohammad Danesh Science and Technology University (HSTU), Dinajpur. The experiment was laid out in a two factorial complete randomized design (CRD) with three replications. Factor-A: Three varieties were V₁ = Binadhan-7, V₂ = BRRI dhan56, V₃= BRRI dhan66 and Factor-B: Three fertilization treatment were: F₁ = Control (inorganic), F₂ = compost 20 t ha^-1, F₃ = compost 30 t ha^-1. The soil was collected from the arable land of Crop physiology and Ecology Research Field, Hajee Mohammad Danesh Science and Technology University (HSTU), Dinajpur from a depth of l5 cm. The collected soil was sun dried for a week, and the weeds were removed. Fifteen- kilogram soil was taken into each pot. Thus the pots were ready for planting. The pots were placed in the selected space of the research field of Crop Physiology and Ecology, HSTU, Dinajpur in 18 rows and 3 columns. The row to row and column to column distance was maintained properly. The amounts of N, P, K, S and Zn fertilizers required per pot (control) were calculated as per the weight of soil. The full amount of TSP, MoP, gypsum and zinc sulphate was applied as basal dose before transplanting of rice seedlings for F₁ fertilization (control). Poultry litter based composts were applied150 g pot^-1 for F₂ fertilization and 225 g pot^-1 for F₃ fertilization. The compost used in this research was made by Kobra (2016). Composting material was poultry manure, sawdust, rice husk and ash. Chemical compositions of poultry litter based compost were N-1.6%, P-1.21%, and K-0.35% (Kobra, 2016). The seedlings of rice (var. Binadhan-7, BRRI dhan56and BRRI dhan66) were collected from BADC, Dinajpur. During seedling growing, no fertilizers were used. Proper water and pest management practices were followed whenever required. Forty days old seedlings of rice were carefully transplanted on July 23, 2018 in well puddle pots. Three seedlings were sown in each pot. Intercultural operations were done to ensure the normal growth of the crop. Plant protection measures were followed as and when necessary. Soil N, P, K, S, pH, organic matter and organic carbon were measured. Soil analysis was done following standard methods at SRDI, Nashipur, Dinajpur. The data obtained for different parameters were statistically analyzed to find out the significant difference between chemical fertilizers and poultry litter based composts on the yield of transplant aman rice. The mean values of all the characters were calculated and analysis of variance was performed by MSTAT-C statistical software. The significance of the differences among the treatment means was estimated by Duncan’s Multiple Range Test (DMRT) at 5% level of probability (Gomez and Gomez, 1984).

Achievement/Findings:

According to the present study, it could be suggested that the rice is grown with Compost-30 t ha^-1 along with var.Binadhan-7) revealed to get the optimum yield. However, these findings need to be further investigated and evaluated in the different agro-ecological zone before the final recommendation for the farmers.
