Abstract/ Executive Summary:

Experiments were conducted to assess the effects of USG on the number of branch and fruit production, fruit length, weight and yield of brinjal (Solanum melongena: cv Shingnath), compared to prilled urea as N source. The study was conducted at farming systems research and development site, Palima, Tangail district under AEZ 8 of Bangladesh during 2000, 2001 and 2002 using randomized complete block design (RCBD) with five treatments replicated 6 times. The treatments were T₁= N₇₈P₃₆K₆₆S_I7CD_3t (Recommended dose for high yield goal (HYG), N as prilled urea), T₂= N₇₈P₃₆K₆₆S_I7CD_3t (Recommended dose for HYG, N as USG), T₃= N₆₅P₃₆K₆₆S₁₇CD_3t (N 10%< Recommended dose as USG), T₄= N₅₂P₃₆K₆₆S₁₇CD_3t (N 20% Recommended dose as USG) and T₅ = N₆₀P₃₅K₆₀S_oCD_5t (Farmers' dose, N as Prilled urea). USG had significant (P ≤0.05) effect on the brinjal fruit yield giving higher profits. Thus USG as N₇₈P₃₆K₆₆S_I7CD_3t was beneficial for brinjal cultivation in terms of yield and economics.

Location: Farming Systems Research and Development site, Palima, Tangail

Start Date: 00-00-2000

End Date: 00-00-2003

Program Area: Crop-Soil-Water Management

Commodity: Brinjal

Objectives:

To determine the optimum and economic dose of USG on the yield and yield attributes of brinjal.

Methodology:

The experiment was carried out in the medium highland of Agro-ecological Zone (AEZ)-8 at the Farming Systems Research and Development site, Palima, Tangail during the rabi season of the years 2000-2001, 2001-2002 and 2002-2003. Before initiation of the experiment, soil samples were collected from a depth of 0-20 cm for each replication and analysed by ASI methods. The chemical properties of this soil are presented. Soil is slightly acidic in reaction with medium contents of organic matter, very low content of total nitrogen and phosphorus, low in potassium, sulphur and boron and high in zinc. The rainfall during November, December, January and February were 0, 11, 3 and 177 mm in 2000-2001, 0, 0,13 and 146 mm in 2001-2002 and similar in 2002-2003. The mean maximum temperature during November, December, January and February were 29.5, 25.5, 25.4 and 28.4 ºC in 2000-2001, 30.1, 25.8, 21.0 and 28.3ºC in 2001-2002 and so on in 2002-2003. The experiment was laid out in a Randomized Compete Block Design (RCBD) having 6 dispersed replications. Five treatments imposed were T₁= N₇₈P₃₆K₆₆S_I7CD_3t (Recommended dose for high yield goal (HYG), N as Prilled urea), T₂= N₇₈P₃₆K₆₆S_I7CD_3t (Recommended dose for HYG, as USG), T₃= N₆₅P₃₆K₆₆S₁₇CD₃₁ (N 10%4= N₅₂P₃₆K₆₆S₁₇CD_3t (N 20% < Recommended dose as USG) and T₅= N₆₀P₃₅K₆₀S_oCD_5t(Farmers' dose, N as Prilled urea). Fertilizer dose for each treatment were calculated on the basis of soil test values according to fertilizer recommendation guide . Farmers' dose was identified by the average dose of 30 farmers, practiced in that area. The unit plot size was 8m x 5m and the variety was Singnath. The 35 days old brinjal seedlings were transplanted on 6 November 2000 to 8 November 2000 in a spacing of 60 cm x 60 cm. Except prilled urea and USG, all other fertilizers and 50% MP were applied during the final land preparation. For each year, USG was applied at 21 days after transplanting (DAT) in ring method as 9-10 cm apart from the seedling base and 7-8 cm depth in soil. Prilled urea was applied as 3 equal splits at 21, 35 and 55 DAT and covered with soil properly. The rest 50% MP was applied with USG and prilled urea at 21 days after transplanting. Three irrigations were applied at 22, 36 and 56 DA T. Three weedings and mulching were done at 18, 33 and 53 DA T. Bacterial wilt was observed and controlled by using Diathen M-45 and Nogos 50 EC was used to control fruit and shoot borer. The crop harvesting continued during the month of February to March. Data on yield and yield contributing characters were recorded from ten plants selected randomly for each plot and total yield was calculated through average plant yield by multiplying plant population. Cost and return analyses were done based on the data recorded at farm-gate prices. Data were collected and analyzed statistically using MSTATC package and means were separated by DMRT at 5% level of significance.

Achievement/Findings:

Brinjal fruit yield and relevant cost-benefit ratio as revealed in the investigation suggest that USG as an N source is more potential than pri lied urea. Based on yield and economic analysis, it can be concluded that USG is more profitable for brinjal cultivation compared with prilled urea.
