Abstract/ Executive Summary:

To study the effect of cowdung and neem leaf (Azadirachta indica) on the growth and development of stem amaranth (Amaranthus oleraceus), an experiment was conducted in experimental plots under a research project, Department of Agroforestry, Bangladesh Agricultural University, Mymensingh following Randomized Block Design with two factor named cowdung and doses of chopped neem leaf with nine treatments and three replications (M₀N_0, M₀N_1, M₀N_2, M₁N_0, M₁N_1, M₁N_2, M₂N_0, M₂N_1, M₂N₂) from 20 February 2008 to 30 April 2008. Plant height (cm), leaf number, stem diameter (mm), plant weight at harvest (g), and yield (t ha^-1) were recorded at 14, 21, 28, 35, 42, 49, 56, and 63 days after sowing with the help of a meter scale and weight machine. It was evident that the maximum value of collected data was found from 10 t ha^-1 of cowdung with 2 t ha^-1 of neem leaf (M₂ x N₂) interaction. Whereas the minimum value was obtained from the interaction of control (M₀ x N₀) treatment at 14, 21, 28, 35, and 56 DAS and the treatment combinations of 5 t ha^-1 cowdung with 1 t ha^-1 neem leaf (M₁ x N₁) and 10 t ha^-1 of cowdung with no neem leaf (M₂ x N₀) was statistically similar. So, it is evident that 10 t ha^-1 of cowdung with 2 t ha^-1 of neem leaf is beneficial for the production of stem amaranth as this combination influenced the plant height, leaves per plant, stem diameter, and yield of stem amaranth.

Keywords: Cowdung, Neem leaf, Stem Amaranth

Start Date: 00-02-2008

End Date: 00-04-2008

Program Area: Crop-Soil-Water Management

Commodity: Cowdung, Amaranth

Objectives:

To study the combined effect of cowdung and neem leaf on growth, development, and yield of stem amaranth.

Methodology:

The experiment was conducted in the research field of the Department of Agroforestry, Bangladesh Agricultural University, Mymensingh from 20 February to 30 April 2008. The trail was set up on February 20, 2008, following Randomized Block Design (RCBD) with three replications of nine treatments (M₀N_0, M₀N_1, M₀N_2, M₁N_0, M₁N_1, M₁N_2,M₂N_0, M₂N_1, M₂N₂) where there were two factors. The stem amaranth (Amaranthus oleraceus) variety used in the experiment was the Kharif season variety named “Red Tower” with different doses of cowdung and chopped neem ((Azadirachta indica)) leaves. Different doses of manure (M₀ = 0g/ control, 750g/5 t ha^-1, M₂ = 1500g /10 t ha^-1) and Chopped Neem leaf (N₀ = 0g /control, N₁ = 150g /1 t ha^-1/ M₂ = 300g /2 t ha^-1) were set up at this experiment. Well decomposed cowdung and fine chopped and semi-dried neem (Amaranthus oleraceus ) were used obtained at the experiment through two hours of sun drying and 22 hours air drying the collected leaves. The seed was sown in a continuous line sowing method on 5^th March 2008 maintaining an inter-row distance of 40 cm and 2 cm depth where seed rate was 1 kg ha^-1 where each plot was 1.5 m x 1 m = 1.5 m². The different intercultural operations such as weeding, thinning out, irrigation and mulching were done as and when necessary. Data on different parameters named plant height (cm), leaf number, stem diameter (mm), plant weight at harvest (g), yield (t/ha) from 10 plants per plot were recorded. The height of plants was measured in centimeters from the ground level to the tip of the shoot at the unit plot at 14, 21, 28, 35, 42, 49, 56, and 63 days after sowing with the help of a meter scale and the stem diameter was collected from the same sample plants at 21, 28, 35, 42, 49 56 and 63 days after sowing in millimeter. The collected data were analyzed using the computer MSTAT-C program by using the “Analysis of variance” (ANOVA) technique. Mean separation was done by Duncan’s Multiple Range Test (DMRT).

Achievement/Findings:

It can be concluded interaction effect of 10 t ha^-1 of cowdung with 2 t ha^-1 of neem leaf is beneficial for the production of stem amaranth as this combination influenced the different parameters named plant height, leaves per plant, stem diameter, plant weight at harvest, and yield of stem amaranth. It is also notified that no use of mentioned organic sources resulting less production of stem amaranth.
