Abstract/ Executive Summary:

The experiment was conducted at the BINA sub-station, Rahmatpur, Barishal, during the period from April 2020 to August 2020 to investigate the effect of nitrogen on the yield of transplant Aus rice cv. Binadhan-19. The experiment comprised four levels of nitrogen viz (a) N₀ (zero nitrogen), (b) N₁ (90 kg N/ha), (c) N₂ (110 kg N/ha) and (d) N₃ (130 kg N/ha). Nitrogen fertilizer was applied at two splits. The experiment was laid out in a randomized complete block design with three replications. Results revealed that plant height, effective tiller, non-effective tiller, flag leaf length, filled gran, unfilled grain, and 1000 grain weight were increased with increasing nitrogen doses to 110 kg N ha^-1. Furthermore, the highest grain weight was recorded in 110 kg N ha^-1 due to superior performance of yield contributing characters of BInadhan-19. A positive correlation was found between grain yield and total dry matter production. The experimental results concluded that 110 kg N ha^-1 would be the best dose for higher gain yield in Binadhan-19 in aus season.

Program Area: Crop-Soil-Water Management

Commodity: Nitrogen, Rice

Objectives:

To determine nitrogen fertilizer's effect on yield and yield contributing characters of Binadhan-19.

Methodology:

The experiment was carried out at the BINA sub-station, Rahmatpur, Barishal, during the period from April 2020 to August 2020 to investigate the effect of nitrogen on the yield of transplant Ausrice cv. Binadhan-19. The experimental site belongs to the Ganges Tidal Floodplain (AEZ 13), having dark grey soil and located at 240 75´ N latitude and 90050´ E longitude having an altitude of 18m above the mean sea level. Active Ganges Floodplain (3,334 sq km) this region occupies unstable alluvial land and adjoins the Ganges River. Complex mixtures of calcareous sandy, silty and clayey alluvium are found in this area. Soils are low in organic matter and slightly alkaline in reaction. The level of overall fertility is medium but deficient in N (AEZ 13). The soil type of experimental site located Babuganj Upazila, Barisal clay loam 13 Sand 30 %, Silt 38 %, and Clay 32 %. The experimental field was medium-high land with moderate drained conditions. The land was sandy loam in texture, having a soil pH value of 6.5, low in organic matter content. Binadhan-19 was developed from NERIKA-10 through radiation and released in 2017. The Levels of nitrogen were as follows: Levels of nitrogen (kg ha^-1): i. N₀ = Control ii. N₁ = 90 kg N/ha at 2 splits iii. N₂ = 110 kg N/ha at 2 splits iv. N₃ = 130 kg N/ha at 2 splits Experimental design and data collection The seeds of Binadhan-19 were immersed in water for 24 hours. The seeds were then taken out of the water and kept thickly in gunny bags and sprouted seeds were sown in the seedbed. The experiment was laid out in a randomized complete block design (RCBD) with three replications. Each of the replication represented as a block in the experiment. Each block was divided into three-unit plots. All the treatments were randomly allocated in the experimental plots. Altogether there were twelve-unit plots in this experiment. The size of the plot for a unit was (4.0 m x 3.0 m). 1m and 0.5 m, respectively, were the distances between replications and between plots. Intercultural operation and irrigation were done when needed. The rice plant was harvested when about 90% of the grains turned to yellowish color. Five randomly selected plants per plot except border rows were calculated for data collection data on yield contributing characters at harvest. Grain yield was taken from one square meter and converted to tons per hectare (ha). Statistical Analysis The collected data were analyzed with the ANOVA technique and the mean differences were adjudged by Duncan’s Multiple Range Test Gomez and Gomez (1984) using statistical computer packages MSTAT.

Achievement/Findings:

Different levels of nitrogen application had a significant influence on morphological, yield, and yield attributes. Results revealed that plant height, effective tiller, non-effective tiller, flag leaf length, filled gran, unfilled grain, and 1000 grain weight were increased with increasing nitrogen doses to 110 kg N ha^-1. The highest grain weight was recorded in 110 kg N ha^-1 due to superior performance of yield contributing characters of BInadhan-19. A positive correlation was found between grain yield and total dry matter production. To sum up, 110 kg N ha^-1 would be the best dose for higher yield production of Binadhan-19 in aus season.
