Abstract/ Executive Summary:

An experiment was conducted to evaluate the effects of different sources of organic nitrogen viz, urea, household wastes, poultry manure and cowdung on growth, yield and nutrient uptake by maize. The experiment was laid out in a RCBD taking eight treatments with three replications. Growth parameters, yield attributes and yield of maize were the hest with substitution of 25% of the recommended dose of fertilizers applied through poultry manure. The highest grain yield of maize (7.70 t/ha) was recorded in treatment receiving 75% N from urea and 25% N from poultry manure. The same treatment produced 121.15% higher grain yield over control. Combined application of organic manures along with chemical fertilizers showed positive effects on N, P, K and S contents and their uptake by grain and stover of maize. The highest uptake of N (173.30 kg/ha), P (33.08 kg/ha), K (164.18 kg/ha) and S (20.36 kg/ha) by maize were observed in treatment receiving 75% N applied through urea in combination with 25% N applied through poultry manure. The effect of poultry manure was most pronounced than that of the cowdung and household wastes.

End Date: 00-00-2009

Program Area: Crop-Soil-Water Management

Commodity: Maize, Organic fertilizer

Objectives:

To assess the effect of combined application of inorganic fertilizers and organic manures on the growth, yield and nutrient uptake by maize.

Methodology:

The experiment was carried out at Bangabandhu Sheikh Mujibur Rahman Agricultural University Reasearch Farm, Gazipur, Bangladesh during Rabi season of 2008-2009. The experimental soil belongs to the Salna Series of AEZ 28 and (Madhupur Tract) classified as InceptisolS. The experimental soil was silty clay loam having soil pH 6.12, organic carbon 0.854%, total nitrogen 0.077%, available P 9.42 ppm, exchangeable K 0.18% and avgilable S 10.31 ppm. The experiment was laid out in RCBD taking eight treatments. The total number of plots was 8 x 3=24; each plot size was 4 m x 3m accommodating 35 plants with a row to row and plant to plant spacing of 75 cm X 45 cm, respectively. The test crop was maize (Zea mays) variety (BARI Hybrid maize - 5). Well decomposed household wastes (HW), poultry manure (PM) and cow-dung (CD) were applied as per treatments one week before final land preparation and thoroughly mixed with the soil. Phosphorus from triple super phosphate (TSP), potassium from murate of potash (MoP), sulphur from gypsum and zinc from zinc oxide and 1/3 nitrogen from urea were applied two days before final land preparation. Rest of the nitrogen from urea was top dressed in two equal splits at 35 and 65 days after seed sowing: Seeds were sown maintaining line to lint distances of 75 cm and seed to seed distances of 45 cm. Two seeds were sown per hill at a depth of 2.5 cm. The intercultural operations were done as and when necessary. Harvesting was done plot wise after full ripening of the crop. Harvesting was completed .within April 2009. From each plot 10 plants were randomly selected to keep records on yield and yield contributing characters. The selected plants were collected before the crop was harvested, and the necessary information was recorded accordingly. The grain and stover samples were also kept for chemical analyses. The initial and post harvest soil samples of 0 - 15 cm depth were collected from each plot. Soil pH was determined by a glass electrode pH meter; organic carbon by wet oxidation method; total nitrogen by Microjeldahl method; available P. exchangeable K and available S by standard methods. The analysis of variance for the crop character and also the nutrient content of the plant samples were done following the ANOVA and the mean values were adjusted by DMRT.
