Abstract/ Executive Summary:

A field experiment was carried out at the Soil Science Field Laboratory, Bangladesh Agricultural University (BAU), Mymensingh during boro season of 2011 to study the effects of poultry manure and water hyacinth as organic sources of phosphorus on the growth and yield of rice, cv. BRRI dhan29 cv.BRRI dhan29.The experiment was laid out in a randomized complete block design with seven treatments and three replications. The treatments were T₁: Control (no fertilizer, no manure), T₂: 100% recommended fertilizer dose, T₃: 60% recommended fertilizer dose+ 40% poultry manure, T₄: 80% recommended fertilizer dose + 20% poultry manure, T₅: 60% recommended fertilizer dose + 40% water hyacinth, T₆: 80% recommended fertilizer dose + 20% water hyacinth, T₇: 50% poultry manure + 50% water hyacinth. Poultry manure and water hyacinth were applied before ten days of transplantation. Recommended doses of N @ 125 kg ha-1 from urea was applied in three equal splits. Recommended doses of P, K, S and Zn from TSP, MoP, gypsum and zinc oxide, respectively were added during final land preparation. The grain and straw yields as well as the yield contributing characters like plant height, effective tillers hill^-1, panicle length, grains panicle^-1 and 1000-grain weight were significantly influenced due to different treatments. The highest grain yield of 5.92 t ha^-1 was recorded in T₃ (60% recommended fertilizer dose + 40% poultry manure). The highest straw yield of 7.35 t ha^-1 was also noted in the treatment T₇ (50% poultry manure + 50% water hyacinth). While the lowest yield in both grain and straw was recorded in control treatment (T₁) .The overall results indicated that application of 60% recommended fertilizer dose and 40% poultry manure was the best for grain and straw production. Application of poultry manures and water hyacinth is more beneficial to rice cultivation (BRRI dhan29) than that of chemical fertilizers. Among the organic manures, poultry manure had better performance on the grain and straw yields than that of water hyacinth.

Program Area: Crop-Soil-Water Management

Commodity: Rice

Objectives:

1. To study the effect of poultry manure and water hyacinth as organic sources of phosphorus on yield contributing characters of BRRI dhan29.

Methodology:

A field experiment was conducted at the Soil Science Field Laboratory of Bangladesh Agricultural University (BAU), Mymensingh during boro season of 2011 in order to evaluate the effects of poultry manure and water hyacinth as organic sources of phosphorous on the growth and yield of rice. The soil belongs to Sonatala Series under the AEZ, Old Brahmaputra Floodplain. The soil was silt loam in texture having pH 6.71, CEC 14.31 me/100 g soil, organic matter content 1.69%, total N 0.097%, available P 10.5 ppm, exchangeable K 0.14 me/100 g soil and available S 13.7 ppm. The experiment was designed with seven treatments and laid out in a randomized complete block design (RCBD) with three replications. The unit plot size was 4 m×2.5 m and the total numbers of plots were 21. The treatments were T₁: Control (No fertilizer, no manure), T₂: 100% recommended fertilizer dose, T₃: 60% recommended fertilizer dose+ 40% poultry manure, T₄: 80% recommended fertilizer dose + 20% poultry manure, T₅: 60% recommended fertilizer dose + 40% water hyacinth, T₆: 80% recommended fertilizer dose + 20% water hyacinth, T₇: 50% poultry manure + 50% water hyacinth. The full dose of poultry manure and water hyacinth was applied to the plots 10 days before transplanting of rice seedlings and the manures were mixed thoroughly with the soil. The recommended dose of N was 125 kg ha^-1. Urea fertilizer was applied in three equal splits at 12, 29 and 28 days after transplanting. Recommended doses of P, K, S and Zn @ 25, 65, 15 and 1 kg ha^-1 from TSP, MoP, gypsum and zinc oxide, respectively, were applied as basal in all the plots except control plots. The seedlings of 35 day-old were transplanted in the experimental plots on 03 February 2011. The intercultural operations were done as and when necessary. The crop was harvested at maturity on 01 June 2011. Ten hills were randomly selected from each plots to record the growth and yield contributing characters like plant height, effective tillers hill^-1, panicle length, number of grains panicle^-1 and 1000-grain weight. The grain and straw yields were recorded plot-wise and expressed on 14% moisture basis. Grain and straw samples were collected, dried, ground, sieved and kept for chemical analysis of phosphorus. The initial soil sample was also analyzed to study the pH, CEC, organic matter content, total N, available P, exchangeable K and available S contents. The data were statistically analyzed to test the level of significance and the means were ranked by DMRT at P≤5%.

Achievement/Findings:

The overall results indicated that application of 60% recommended fertilizer dose and 40% poultry manure was the best for grain and straw production. Application of poultry manures and water hyacinth is more beneficial to rice cultivation (BRRI dhan29) than that of chemical fertilizers. Among the organic manures, poultry manure had better performance on the grain and straw yields than that of water hyacinth.
