Abstract/ Executive Summary:

The experiment was conducted at the Hajee Mohammad Danesh Science and Technology University Farm, Dinajpur, Bangladesh during aman (season July to December) of 2008 to observe the influence of mixed fertilizer with urea on the yield and yield contributing characteristics of rice. The experiment was laid out in a randomized complete block design with three replications. ‘Maharaja’ used as a commercial mixed fertilizer that content N-8%, P-20%, K-14% and S-5%. The fertilizer treatments were arranged considering the requirement of rice according to the soil status and nutrient content of the mixed fertilizer. The experiment consisted of fourteen treatments. All the treatments produced significantly higher grain yield than control. Growth attributes of rice such as fertile tillers hill^-1 and grains panicle^-1 showed higher value with mixed fertilizer @ 225 kg ha^-1 + urea @ 100 kg ha^-1. The highest grain yield was obtained from mixed fertilizer @ 225 kg ha^-1 with urea @ 100 kg ha^-1 that was statistically similar to mixed fertilizer @ 225 kg ha^-1 + urea @ 140 kg ha^-1, mixed fertilizer @ 225 kg ha^-1 + urea @ 180 kg ha^-1 and mixed fertilizer @ 250 kg ha-1 + urea @ 100 kg ha^-1.

Commodity: Rice

Objectives:

1. To study the effect of mixed fertilizer on the yield and yield attributes of rice.

Methodology:

The experiment was conducted at the Hajee Mohammad Danesh Science and Technology University Farm, Dinajpur, Bangladesh during aman season (July to December) of 2008. The experimental site was a medium high land with sandy loam soil having a pH value of 6.0. The experiment was laid out in a randomized complete block design with three replications. ‘Maharaja’ used as a commercial mixed fertilizer that content N-8%, P-20%, K-14% and S-5% as per declaration of the producing company. The fertilizer treatments were arranged considering the requirement of rice according to the soil status and nutrient content of the mixed fertilizer. BR11 was used as a test crop in the experiment. The experiment consisted of fourteen treatments viz.,i) control (no fertilizers)-T₁, ii) Recommended fertilizer of NPKSZn-T₂, iii) Mixed fertilizer @ 200 kg ha^-1 + Urea@ 0 kg ha^-1 -T₃, iv) Mixed fertilizer@ 200 kg ha^-1+ Urea@ 100 kg ha^-1-T₄, v) Mixed fertilizer @ 200 kg ha^-1 + Urea@ 140 kg ha^-1 -T₅, vi) Mixed fertilizer @ 200 kg ha^-1 + Urea @ 180 kg ha^-1 -T₆, vii) Mixed fertilizer @ 225 kg ha^-1 + Urea @ 0 kg ha^-1 -T₇, viii) Mixed fertilizer@ 225 kg ha^-1 + Urea @ 100 kg ha^-1 -T₈, ix) Mixed fertilizer @ 225 kg ha^-1 + Urea @ 140 kg ha^-1-T₉, x) Mixed fertilizer @ 225 kg ha^-1 + Urea @ 180 kg ha^-1 -T₁₀, xi) Mixed fertilizer @ 250 kg ha^-1+ Urea @ 0 kg ha^-1-T₁₁, xii) Mixed fertilizer @ 250 kg ha^-1+ Urea @ 100 kg ha^-1 -T₁₂, xiii) Mixed fertilizer @ 250 kg ha^-1 + Urea @140 kg ha^-1-T₁₃ and xiv) Mixed fertilizer @ 250 kg ha^-1 + Urea @ 180 kg ha^-1-T₁₄. The unit plot size was 4.0m × 2.5m. According to the experimental specification, no fertilizer was used under control treatment. Mixed fertilizer as per treatment and P, K, S and Zn were applied as basal through TSP 65 kg, MP 110 kg, gypsum 87 kg and ZnSO₄ 2.25 kg ha^-1 were applied at final land preparation. Nitrogen was applied in the form of urea @ 138 kg ha^-1 in two equal splits at 20 and 45 days after transplanting. Thirty-day-old seedlings were transplanted in the plots at a spacing of 20 cm × 15 cm using 3 seedlings hill^-1 on 15 July 2008. All other cultural practices were done uniformly as per recommendation. Whole plots were harvested to obtain grain yield. Data were analyzed following the ANOVA technique and mean differences were adjudged with Duncan’s Multiple Range Test (DMRT).

Achievement/Findings:

Growth attributes of rice such as fertile tillers hill^-1 and grains panicle^-1 showed higher value with mixed fertilizer @ 225 kg ha^-1 + urea @ 100 kg ha^-1. The highest grain yield was obtained from mixed fertilizer @ 225 kg ha^-1 with urea @ 100 kg ha^-1 that was statistically similar to mixed fertilizer @ 225 kg ha^-1 + urea @ 140 kg ha^-1, mixed fertilizer @ 225 kg ha^-1 + urea @ 180 kg ha^-1 and mixed fertilizer @ 250 kg ha-1 + urea @ 100 kg ha^-1.
