Performance of Moni Mukta Organic Fertilizer on the Growth and Yield of Wetland Rice

Abstract/ Executive Summary:

The study was conducted at BRRI farm Gazipur (AEZ 28; Land type- Medium High land) in Boro 2005-06 to evaluate the performance of Moni Mukta organic fertilizer with reduce chemical fertilizer. Eight treatments were tested viz. T₁ = absolute control, T₂ = STB doses chemical fertilizer (NPKS@140-28-56-23 kg/ha), T₃ = Moni Mukta(MM)@ 250 kg/ha + 50%STB, T₄ = MM@370 kg/ha + 50% STB, T₅ = MM@500kg/ha + 50% STB, T₆ = MM@250 kg/ha + 75% STB, T₇ = MM@370kg/ha + 75% STB and T₈ = MM@500kg/ha + 75 % STB in Randomized complete block design with 3 replications. The study result showed STB fertilizer dose produced maximum grain and straw yield compared to other treatments. Economic analysis on partial budget proved the highest net benefit Tk. 54840/ha was found in STB followed by MM @ 250kg/ha + 75% STB (Tk. 54208/ ha). Through dominance and marginal analysis, Moni Mukta @ 250 kg/ha + 75% STB is the most economically viable treatment of the experiment. Reduced use of chemical fertilizer positively influences the environment through reducing contamination of air, soil and water. Considering these points it may be suggested that 25% reduction of STB fertilizer along with 250 kg Moni Mukta/ha may be a good combination of organic and inorganic fertilizer to obtain high yield as well as sustaining soil fertility.

Commodity: Organic fertilizer

Objectives:

To evaluate the performance of Moni Mukta organic fertilizer with reduce chemical fertilizer

Methodology:

The study was conducted at BRRI farm Gazipur (AEZ 28; Land type- Medium High land) in Boro 2005-06 with eight treatments viz. T1 = absolute control, T2 = STB doses chemical fertilizer (NPKS@140-28-56-23 kg/ha), T3 = Moni Mukta(MM)@ 250 kg/ha + 50% STB, T4 = MM@370 kg/ha + 50 % STB, T5 = MM@500kg/ha + 50% STB, T6 = MM@250 kg/ha + 75% STB, T7 = MM@370kg/ha + 75% STB and T8 = MM@500kg/ha + 75 % STB. The experiment was laid out in RCB design with 3 replications having unit plot size of 4m x 3m. BRRI dhan29 was used as test crop. Moni Mukta was a nutrient enriched organic fertilizer containing 2.15% total N, 1.5% P, 2.00%K and 2.00% S. Moni Mukta, TSP, MP, Zinc sulphate and Gypsum were applied at final land preparation. Urea was applied in three splits as 34% at basal, 33% at 25 DAT and rest 33% at 5-7 days before PI stage. At maturity the crop was harvested manually from 5 m² area at 15 cm above ground. However, 16 hills from each plot were harvested at ground level for straw yield data. Grain yield was recorded at 14% moisture content and straw yield as oven dry basis.
