Abstract/ Executive Summary:

This study was conducted at the Agroforestry Farm, Department of Agroforestry, Bangladesh Agricultural University, Mymensingh during July to November 2006. In this study, five different tree leaf biomasses (minjiri, ipil-ipil, akashmoni, eucalyptus and mahogoni) were incorporate to the soil to evaluate their effect on the performance of rice cv. BR11 and subsequent soil health and compared with recommended fertilizer as control. The tree leaf biomass significantly influenced the growth, yield and yield contributing characters of rice. The highest grain yield (4.95 t ha^-1) was obtained in the recommended fertilizer dose followed by ipil-ipil, minjiri, akashmoni, eucalyptus and mahogoni (4.33, 4.07, 3.91, 3.88 and 3.83 tha-1) respectively. Among the tree leaf biomass, ipil-ipil performed better yield which was the nearest of the recommended fertilizer dose and the treatment of mahogoni gave the lowest yield. Tree leaf biomasses also significantly influenced the health of soil. Highest amount of nutrients (N, P & K) were added to the soil from ipil-ipil leaf biomass and lowest from mahogoni. Thus it appears that tree leaf biomass could use as alternative to chemical fertilizers which is causing soil and environment pollution.

End Date: 31-12-2006

Program Area: Crop-Soil-Water Management

Commodity: Rice

Objectives:

1. The present work was undertaken to determine the effect of different tree leaf biomass on growth and yield of rice cv. BR11 and subsequent health of soil.

Methodology:

The research work was conducted at the Agroforestry Farm, Department of Agroforestry, Bangladesh Agricultural University, Mymensingh during the period from July-November, 2006. The experiment site is moderately well drained with a silt loam texture having pH 6.5 to 6.8, total N 0.061%, available P 7.80 mg kg^-1 and exchangeable K 0.155 cmol kg^-1 soil. The experiment was set up in Randomized Complete Block Design with three replications. There were six different treatments as follows: T₀: Recommended fertilizer dose (RFD)/ Control, T₁: Minjiri (Cassia siamea) leaf biomass, T₂: Ipil-ipil (Leucaena leucocephala) leaf biomass, T₃: Akashmoni (Acacia auriculiformis) leaf biomass, T₄: Eucalyptus (Eucalyptus camaldulensis) leaf biomass, T₅: Mahogoni (Swietenia macrophylla) leaf biomass. The total number of plot was 6 × 3 = 18; each plot size was 1m × 1m. Rice cv. BR11 was used as the test crop. The selected tree leaf biomasses were collected from the representative trees of Bangladesh Agricultural University Campus and incorporated to the assigned plot before 15 days of transplanting, randomly in each block. 40 days old seedlings of cv. BR11 were transplanted on 29 July 2006 with spacing 20 cm × 15 cm. Two or three healthy seedlings per hill were transplanted in all the plots. After transplanting, necessary cultural operations were done as required. The rice plants were harvested on 18 November 2006 at its full maturity. Necessary crop data were collected at harvest. The soil samples were analyzed to determine N, P, K release from the selected tree leaf biomass and the improvement of soil status. The data were statistically analyzed to test the level of significance and the means were ranked by Duncan’s Multiple Range Test (DMRT).

Achievement/Findings:

Among the tree leaf biomass, ipil-ipil performed better yield which was the nearest of the recommended fertilizer dose and the treatment of mahogoni gave the lowest yield. Tree leaf biomasses also significantly influenced the health of soil. Highest amount of nutrients (N, P & K) were added to the soil from ipil-ipil leaf biomass and lowest from mahogoni. Thus it appears that tree leaf biomass could use as alternative to chemical fertilizers which is causing soil and environment pollution.
