Abstract/ Executive Summary:

A Field experiment was conducted in combination with chemical fertilizers and manure. The treatments were T0 (control), T1 (N100P15K45S20 (Recommended dose), T2 (50% NPKS+5 t ha^-¹ CD), T3 (70% NPKS+3 t ha^-1 CD), T4 (50% NPKS+4t ha^-1 PM ), T5 (70% NPKS+2.4 t ha^-1 PM ), T6 (50% NPKS+10 t ha^-1DH) and T7 (70% NPKS+6 t ha^-1DH). The result demonstrated that the grain and straw yields were significantly influenced by the added fertilizers and manure. Application of 50% of NPKS fertilizers plus 10 t ha^-1 dhaincha produced maximum grain yield (5085 kg ha^-1) which was identical to that obtained with 70% of NPKS with 6 t ha^-1 dhaincha. In case of straw yield, the treatment T7 (70% NPKS+6 t ha^-1DH) produced the highest yield (5470 kg ha^-1) and then (5250 kg ha^-1) yield obtained from T6 (50% NPKS+10 t ha^-1DH) treatment. The grain yield increases over control ranges between 115 to 176%. Grain yield of T. Aman rice was positively correlated with plant height, number of effective tiller, panicle length, filled grains panicle-1and straw yield. The overall findings of this study indicate that the integrated use of fertilizer and manure should be encouraged to address the deteriorating soil fertility and increased crop yield of T. Aman rice.

Commodity: Fertilizer, Organic fertilizer

Objectives:

The objectives of the study is to develop a suitable combination of chemical fertilizers and organic manures for T. Aman rice production.

Methodology:

The experiment was conducted in typical rice growing silt loam soil at the Sher-e-Bangla Agricultural University (SAU) farm, Sher-e-Bangla Nagar, Dhaka during the T. Aman season of 2014. BRRI dhan33, T. Aman rice variety was used in this experiment. Bangladesh Rice Research Institute (BRRI) developed this variety in 1997. Genetic serial no. is BG 850-2, and life cycle ranges from 105-115 days. Heights of mature plants are 100 cm and do not lodge. The experiment was laid out in a randomized complete block design (RCBD). Each block was divided into eight unit plots as treatments with raised bunds around. The plot size was 2 m x 2 m. The fertilizer treatments used in the experiment was based on BARC Fertilizer Recommendation Guide, 2005. Three different types of organic manure (dhaincha, cowdung and poultry manure) were used in this study. The experiment had 8 treatments, viz. control. 100% recommended dose of NPKS and 50% or 30% reduction of NPKS dose plus dhaincha (DH), cowdung (CD) and poultry manure (PM). The treatments were T0: Control, T1: N100P15K45S20 (Recommended dose), T2: 50% NPKS + 5 t ha^-¹ CD, T3: 70% NPKS + 3 t ha^-1 CD, T4: 50% NPKS + 4 t ha^-1 PM, T5: 70% NPKS + 2.4 t ha-1PM, T6: 50% NPKS + 10 t ha^-¹ DH, T7: 70% NPKS + 6 t ha^-¹ DH. The plant height was measured from the ground level to the top of the panicle. From each plot, plants of 10 hills were measured and averaged. The measurement of panicle length was taken from basal node of the rachis to the apex of panicle. Each observation was an average of 10 hills. Ten hills were taken randomly from each plot and total numbers of effective tillers hill^-1 were recorded. Filled and unfilled grains per panicle were counted and averaged from the panicles of ten hills. 1000 grains were taken from the samples and after sun drying the weight was recorded by using electrical balance. The harvested crops was threshed, cleaned, dried and weighed. Straw and grain yields were adjusted to 14% moisture content. Data for every crop parameters and also for the nutrient concentration and nutrient uptake by the plant (grain and straw) were analyzed by using F-test to examine whether the treatments were significant or non-significant (Gomez and Gomez, 1984). The mean comparisons of the treatment were evaluated by DMRT (Duncan’s Multiple Range Test).

Achievement/Findings:

From the present study it may be concluded that BRRI dhan33 responded better to the nutrient supplied from the organic manure in producing grain and straw yields. The study clearly demonstrates that the benefit of using dhaincha as green manure can reduce the N, P, K and S fertilizers for T. Aman rice, giving good growth and yield. BRRI dhan33 can be cultivated profitably in the Tejgaon silt loam soil by using combined application of 50% NPKS fertilizers with 10 t ha^-1 dhaincha. The overall findings of this study indicate that the combined use of fertilizer and manure in T. Aman rice should be encouraged for maintaining rice growth, yield and soil fertility.
