Abstract/ Executive Summary:

A field experiment was conducted at the Central Farm of Bangladesh Agricultural University, Mymensingh, during the period from July to December, 2007 to observe the effect of S and B fertilization on the yield attributes and yield of aromatic rice cv. Kalizira. The experiment comprised of four levels of S and three levels of B viz. 0, 10, 20, and 50 kg S ha^-1 (S₀, S₁₀, S₂₀ and S₅₀) and 0, 2 and 4 kg B ha^-1 (B₀, B₂ and B₄), respectively. The experiment was laid out in a completely randomized block design (RCBD) with three replications. Yield and yield attributes were significantly influenced by the individual application of S and B except plant height and panicle length. The highest values of most the parameters were recorded from the plot fertilized with S₂₀ and B₂. Interaction effect of S and B fertilizer showed significant variation on filled grains, total grains, 1000-grain weight, grain and straw yield. The highest values of most of the parameters were obtained from the treatment combination of S₂₀ B₂except plant height, panicle length, total tillers, straw nitrogen content and straw yield which were highest in the treatment combinations of S₁₀ B₀, S₁₀ B₂, S₁₀ B₄, S₂₀B₄ and S₁₀B₄, respectively. The overall results thus suggest that aromatic rice can be grown in non calcareous soil fertilized with 20 kg S in combination with 2 kg B ha^-1to get higher yield for its large scale production in Bangladesh.

Program Area: Crop-Soil-Water Management

Commodity: Rice

Objectives:

1. To observe the effect of S and B fertilization on the yield attributes and yield of aromatic rice cv. Kalizira.

Methodology:

A field experiment was conducted during Kharif season to examine the effect of S and B on yield attributes and yield of aromatic rice in the central farm of Bangladesh Agricultural University, Mymensingh, during the period from July to December, 2007. The soil was silt loam in texture having pH 6.7 with 1.17% organic matter, 0.09% total N, 11.50 mg kg^-1 available P, 0.06 cmol kg^-1 exchangeable K. The experiment consisted of S and B 0, 10, 20, 50 and 0, 2, 4 kg ha^-1 respectively. Soil samples were randomly collected at 0-15 cm depth during the time of land preparation from twenty five spots of the experimental land and composited. The crop under study was indigenous aromatic rice (cv. Kalizira). This rice genotype was characterized by its scented properties like aroma, size and taste. Sulphur and B fertilizers were applied as per design and treatments from gypsum and borax and all other fertilizers like urea, triple super phosphate, and muriate of potash were applied according to the fertilizer recommendation guide. All chemical fertilizers and one-third of urea were applied during final land preparation and rest of the urea were applied in two instalments. The experiment was laid out in RCBD with three replications. The treatments were randomly distributed to the plots. Individual plot size (4 m x 2.5 m) 10 m²^, space between unit plots is 0.5 m and space between replication is 1m. Intercultural operations like weeding, thinning, gap filling, irrigation, pest control were done as and when necessary to ensure normal growth of crop. After collecting plant samples, the crop was harvested and sun dried for 3-4 days and grains were separated from the plants by beating the bundles with bamboo sticks. The seeds were dried in the sun for 2-3 days to 9% moisture level and cleaned. Soil and plant chemical properties were analyzed following the standard methods. Analysis of variance was done with the help of computer package MSTATC and the mean differences of the treatments were adjudged by LSD test. Total nitrogen was determined by Kjeldahl method. Protein was calculated from percent total nitrogen multiplied by 5.85.
