Abstract/ Executive Summary:

An experiment was carried out with four tomato genotypes viz., CLN-2413, CLN-2418. J-5 and Binatomato-5 in Bangladesh Institute of Nuclear Agriculture, Mymensingh during August to November 2006 to study yield performance of some tomato genotypes in early winter season. Genotypic variations for plant height, number of branches, leaf, fruit, flower plant^-1, leaf area, leaf weight, stem weight, total dry matter plant^-1, NRA, vitamin C (green and ripe fruit), average fruit weight and harvest index (HI) were significant. Genotypic difference on root weight, chlorophyll content (SPAD reading), total sugar, reducing sugar, amino acid in leaves, root shoot ratio and total fresh weight of fruits was not significant. The result revealed that the genotypes CLN-2418 and Binatomato-5 showed the best performance compared to other genotypes. Among the genotypes, the tallest and shortest plants were recorded in Binatomato-5 and CLN-2413 respective. CLN-2413 produced the lowest number of fruits. Binatomato-5 and J-5 produced the maximum number of branches whereas minimum was in CLN-2418. Binatomato-5 produced the highest number of fruits and fruit cluster with the lowest fruit weight but CLN-2418 yielded the highest total fruit weight with medium number of fruits. J-5 resulted the lowest number of fruits, flower and harvest index.

Keywords: Tomato, Morpho-physiological attributes, Yield

Location: Bangladesh Institute of Nuclear Agriculture (BINA), Mymensingh

Start Date: 00-08-2006

End Date: 00-11-2006

Program Area: Variety and Species

Commodity: Tomato

Objectives:

The objectives were to study yield performance of tomato genotypes in early winter and to identify early tomato genotype for high yield potential and quality.

Methodology:

An experiment was carried out with four tomato genotypes namely, CLN-2413, CLN-2418. J-5 and Binatomato-5 in Bangladesh Institute of Nuclear Agriculture (BINA), Mymensingh during the period from August to November 2006. The experimental treatments consisted of four tomato genotypes namely, CLN-2413, CLN-2418. J-5 and Binatomato-5. The experiment was laid out in a Randomized Complete Block Design with three replications. The soil for the experimental pot was collected from BINA farm. Each pot was filled with 10 kg of soil. Nitrogen, phosphorus, potassium and cow dung @ 5.5 g, 4.5 g, 2.5 g and 700 g pot^-1, respectively were used corresponding to 550 kg urea, 450 kg TSP, 250 kg MP and 12 ton cow dung ha^-1. Seedlings of 30 days old were transplanted in the experimental pots in the last week of September 2006. Immediately after transplanting the seedlings were properly watered. Data on morpho-physiological, yield attributes and yield were recorded. The recorded data were compiled and tabulated in proper form and analysis of variance was done following CRD with the help of computer package program MSTAT-C by Russell (1986). Duncan’s Multiple Range Test (DMRT) was used to compare the differences among the variety means (Gomez and Gomez, 1984).

Achievement/Findings:

Genotypic variations for plant height, number of branches, leaf, fruit, flower plant^-1, leaf area, leaf weight, stem weight, total dry matter plant^-1, NRA, vitamin C (green and ripe fruit), average fruit weight and harvest index (HI) of tomato genotypes were significant. Genotypic difference on root weight, chlorophyll content (SPAD reading), total sugar, reducing sugar, amino acid in leaves, root shoot ratio and total fresh weight of fruits was not significant. The result revealed that the genotypes CLN-2418 and Binatomato-5 showed the best performance compared to other genotypes. Among the genotypes, the tallest and shortest plants were recorded in Binatomato-5 and CLN-2413 respective. CLN-2413 produced the lowest number of fruits. Binatomato-5 and J-5 produced the maximum number of branches whereas minimum was in CLN-2418. Binatomato-5 produced the highest number of fruits and fruit cluster with the lowest fruit weight but CLN-2418 yielded the highest total fiuit weight with medium number of fruits. J-5 resulted the lowest number of fruits, flower and harvest index.
