Abstract/ Executive Summary:

This experiment was conducted at the Agronomy Farm, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during October 2008 to March 2009 to study the growth and yield response of tomato. Experiments consisted of four nitrogen levels viz. Control: No nitrogen, N₁: 100 kg/ha, N₂: 150 kg/ha and N₃: 200 kg/ha using Randomized Complete Block Design with three replications. Tallest plant (91.4 cm) was found from N₂. Maximum number of leaves (97.8/plant), number of branches (10.7/plant), number of flowers (6.4/cluster), number of fruits (5.1/cluster), number of clusters (15.3/plant), fruit diameter (15.6 cm), individual fruit weight (73.1 g), yield (22.2 kg/plot and 61.4 t/ha) and Total Soluble Solid (TSS) (5.5%) were found from N₂ while minimum from N₀. It was observed that yield, growth parameters and yield contributing attributes are positively correlated with nitrogen levels except control; 150 kg/ha nitrogen was found the best compared to other nitrogen level used in this experiment for growth and yield of BARI tomato - 9.

Keywords: Solanum lycopersicum, Growth and yield

Location: Agronomy Farm, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh

Start Date: 00-10-2008

End Date: 00-03-2009

Program Area: Crop-Soil-Water Management

Commodity: Tomato

Objectives:

To study the effect of nitrogen on the growth and yield of tomato.

Methodology:

Location and period of the study: This experiment was conducted at the Agronomy Farm, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during October 2008 to March 2009. Genetic materials: BARI Tomato-9 was used in the experiments and seeds were collected from the Horticulture Research Centre, Bangladesh Agricultural Research Institute (BARI) at Joydebpur, Gazipur. Treatments and design: The experiment consisted of four levels of nitrogen doses viz. Control: No nitrogen, N₁: 100 kg/ha, N₂: 150 kg/ha and N₃: 200 kg/ha using Randomized Complete Block Design with three replications. Plot size: The size of unit plot was 2 m ? 1.8 m. The distance between the blocks was 1 m and that between plots was 50 cm. Fertilizers and Manure: 10 tones cow dung, 150 kg TSP and 250 kg MP per hectare were applied in the experimental plot. Entire cow dung, TSP and ½ of MP was applied during final land preparation. Urea was applied according to the treatments. The entire urea and rest of MP were applied in three equal installments at 15, 30 and 50 days after transplanting in the field. Transplantation and spacing: Healthy and uniformed sized 30 days old seedlings were taken separately from the seedbed and were transplanted in the experimental field on 28 November 2008 maintaining spacing of 60 cm and 50 cm between the rows and plants respectively. Data collection: Data were collected on plant height, number of leaves, number of branches, number of cluster, number of flowers, number of fruits, fruit length, fruit diameter, individual fruit weight, yield/plot, yield/ha, and TSS content. A fruit was sliced into two halves horizontally with a sharp knife and a small quantity of juice from them was used to determine TSS in percentage with TSS meter. Statistical analysis: Collected data were statistically analyzed using MSTAT-C statistical package program and mean for all the treatments was calculated. Difference between treatments means were determined by Least Significance Difference (LSD) test at 5% level of significance.

Achievement/Findings:

Nitrogen applied at the rate of 150 kg/ha gave high yield. Growth parameters and yield contributing attributes of tomato also performed better with 150 kg/ha; whereas control treatments showed minimum results for yield and growth performance. 150 kg/ha would be beneficial for the farmers to obtain optimum growth and higher yield of BARI tomato-9.
