Abstract/ Executive Summary:

A field experiment was conducted at the Horticultural Farm of Bangladesh Agricultural University (BAU), Mymensingh during the period from December 2004 to April 2005 to evaluate the effect of manures and fertilizers on the yield of brinjal. There were five treatments consisting of organic, inorganic and combined sources of nutrients, of which the combined treatment (60 % organic +40% inorganic) showed the best performances. The maximum branching (20.1) with the highest number fruits/plant (15.2), fruit length (14.1 cm) and fruit diameter (4.3 cm) were found combined application of manures and fertilizers. The highest yield (45.5 t ha^-1) was also obtained from the combined application of organic and inorganic sources of nutrients. Application of mustard oil cake or poultry manure alone gave better performance compared to only chemical fertilizers. The organic matter content and availability of N, P, K and S in soil were increased by organic matter application. On the other hand soil pH was increased with chemical application than organic.

Start Date: 00-12-2004

End Date: 00-05-2005

Program Area: Crop-Soil-Water Management

Commodity: Brinjal

Objectives:

1. To investigate the effects of organic manure and inorganic fertilizer alone or in combination on yield and yield contributing characters of brinjal and on soil properties.

Methodology:

The experiment was carried out in a Randomized Complete Block Design (RCBD) from December 2004 to April 2005 at the Horticulture Farm of Bangladesh Agricultural University (BAU), Mymensingh. The test crop was brinjal (cv. Shingnath). The treatments, were T₁ (Cowdung @ 22857 kg ha^-1) , T₂ (mustard oil cake @1600 kg ha^-1 ), T₃ ( poultry manure @ 5000 kg ha^-1), T₄ ( chemical fertilizers @ 174 kg urea ha^-1 , 125 kg TSP ha^-1 and 50 kg MoP ha^-1) and T5 (20% cowdung + 20% mustard oilcake + 20% poultry manure + 40% N+ P +K fertilizers). The N, P and K contents of the manures were tested in the laboratory and according to the results, the doses of manures were set in such a way that all the treatments contain same amount of N, P and K. Five plants were selected randomly from each unit plot to record yield contributing characters. To study the effect of treatments on the physical and chemical properties of soil, the samples were tested in the soil testing laboratory of the Department of Soil Science, BAU. Soil pH was measured by glass electrode pH meter; organic carbon by wet oxidation method; Total N by micro kjeldahl method; exchangeable K and available S and P by standard method. The collected data were analyzed statistically by F-test to examine the treatment effects and the mean differences were adjudged by Duncan’s Multiple Range Test (DMRT)

Achievement/Findings:

It may be concluded that in brinjal production combined application of organic and inorganic sources of nutrients can be more productive and this will also sustain the fertility and productivity of soil.
