Abstract/ Executive Summary:

The experiment was conducted with Sonatola, Silmondi soil during 2002 in order to examine the effect of fertilizers alone and in combination with mustard oil cake on the yield and yield attributes of boro rice. The highest grain yield (6.48 t ha^-1) was produced by the combined effect of N₁₁₄ P₈ K₅₀ S₁₀ Zn1.4 B_1.4 kg ha^-1 with 0.5 t ha^-1 mustard oil cake (T₂) but the yield did not differ significantly with that obtained from the treatments N₁₄₀ P₁₇ K₅₆ S₁₀ Zn_1.4B_1.4 (T₁), N₁₀₀P₁₂K₄₀ S₇Zn₁ B₁ (T₃) and N₅₈ P₂₅ K₃₃S₀ Zn₀ B₀ (T₄). The lowest grain yield (1.45 t ha^-1) was recorded from the control treatment T₆(N₀P₀K₀S₀Zn₀B₀). The economic analysis indicated that the highest yield was found in the treatment T₂ but the marginal rate of return was obtained maximum (961%) in T₃ treatment.

Keywords: Fertilizer, lPNS, Boro rice, Yield

Location: Melandah Unazila, Jamalpur district, Bangladesh

Start Date: 00-00-2002

End Date: 00-00-2002

Program Area: Crop-Soil-Water Management

Commodity: Organic fertilizer, Fertilizer

Objectives:

To evaluate the effect of chemical, fertilizers alone and in combination with mustard oil cake on the growth and yield of boro rice in the farmer's filed, and
To determine the profitability of different combinations of fertilizers.

Methodology:

The experiment was conducted at the Multi-location Test Site, Melandah, Jamalpur, Bangladesh during 2002. The experiment was laid out in a randomized complete block design with six dispersed replications. Five levels of fertilizer combinations viz., T₁ = Estimated mineral fertilizer dose based on the soil test value for high yield goal (HYG); T₂ = Integrated Plant Nutrient System (IPNS) basis fertilizer management with mustard oil cake for high yield goal (HYG); T₃ = Recommended fertilizer dose based on Fertilizer Recommendation Guide '97 (Anon., 1997); T₄ = Farmers practice and T₅ = Absolute control. The unit plot size was 8m x 5m. Rice variety BRRl dhan29 was transplanted in line sowing on February 4, 2002. Two-hand weeding was done at 20 and 40 days after transplanting. The source of NPKSZn and B were urea, TSP, MP, gypsum, boric acid and zinc sulphate. Total TSP, MP, gypsum, boric acid and zinc sulphate were applied at final land preparation. Urea were applied three equal splits. The land was prepared properly as for the crop requirement. Dimecron was applied when rice stem borer was attacked. The crop was harvested on May 30, 2002 at full maturity. Ten plants were collected prior to harvest from each plot to record data on yield attributes. Data on grain and straw yield were recorded from 6m² area. Data were analyzed statistically and the means were separated by DMRT.

Achievement/Findings:

From the soil analysis value, it was shown that the soil of the experimental plot deficit of organic matter as well as NPK, hence the yield of Boro rice increase in T₂. Treatments T₄ and T₅ produced significantly lower grain yield than T₂. The highest straw yield (6.80 tha^-1) produced in the treatment T₂ and it was statistically similar with T₁ and T₃ treatments. The lowest straw yield (1.65 tha^-1) was recorded from control treatment (T₅). However, in all the cases, the control treatment produced the lowest yield and yield contributing characters. The lowest grain yield (1.45 t ha^-1) was recorded from the control treatment T₆ (N₀P₀K₀S₀Zn₀B₀). The economic analysis indicated that the highest yield was found in the treatment T₂ but the marginal rate of return was obtained maximum (961%) in T₃treatment.
