Abstract/ Executive Summary:

Five aromatic rice varieties namely Kalizira, BR-5, BRRI dhan34, Chinigura and Tulsimala were grown in the central farm of Bangladesh Agricultural University, Mymensingh during aman season (July to December, 2010) using two sources of fertilization viz. poultry manure @ 6 t ha^-1 and 100% inorganic fertilizer constituting urea, TSP, MoP, gypsum and zinc sulphate @ 150, 100, 70, 60 and 10 kg ha^-1, respectively to characterize these varieties through their nutritional constituents. The experiment was laid out in a RCBD design with three replications. Variety and fertilization singly or in combination showed significant effect on nutrient contents and nutrient uptake by aromatic rice. The highest grain N, Ca and Mg contents and the highest N, P, K, S, Ca and Mg uptake were determined in Chinigura while the highest P and K contents were in BRRI dhan34. Nutrient contents and their uptake by rice straw were also significantly influenced by variety and fertilization and followed similar pattern like grain. Poultry manure treated rice contained higher amounts of all the nutrients than the rice treated with inorganic fertilizer. In case of interaction, the highest N, S, Ca and Mg contents and the highest N, P, K, S, Ca and Mg uptake were found in Chinigura fertilized with poultry manure while highest P and K contents were found in BRRI dhan34 treated with inorganic fertilizer.

Commodity: Rice

Objectives:

To examine the effect of poultry manure and inorganic fertilizer on the nutrient contents and their uptake by aromatic rice.

Methodology:

A field experiment was conducted at the central farm of BAU with five aromatic rice varieties viz. Kalizira, BR-5, BRRI dhan34, Chinigura and Tulsimala using two sources of fertilization viz. poultry manure @ 6 t ha-1 and 100% in organic fertilizer. The experiment was laid out in RCBD with three replications and total number of unit plot was 30. The full doses of TSP, MoP, gypsum and zinc sulphate at rates of 100, 70, 60, 10 kg ha^-1, respectively were applied one day before transplanting in 15 plots. The urea was applied in three splits at 15, 30 and 50 days after transplanting (DAT), respectively. Poultry manure @ 6 t ha^-1 was applied in another 15 plots. All intercultural operations were done as and when necessary. Kalizira, BRRI dhan34 and Chinigura were harvested plot-wise at maturity on 4^th December, 2010. Tulsimala and BR-5 were harvested on 15^th December, 2010. Grain and straw samples were separated, dried, cleaned, weighed, ground and stored in appropriate containers. Grain and straw samples were digested in di-acid mixture for the preparation of extract for analysis.

Achievement/Findings:

On the basis of findings it may be concluded that Chinigura fertilized with poultry manure exhibited best performance for nutrient content and their uptake which was identical with BRRI dhan34 with same fertilization.
