Abstract/ Executive Summary:

Waterlogging is a serious abiotic stress which affects plant growth and development due to reduced amount of oxygen supplied to submerged tissues. A pot experiment was conducted to look into the adverse effect of flooding stress on tomato cultivar, Pusharubi at Jute Agriculture Experimental Station, Jagir, Manikganj during September to December, 2018. Thirty days old healthy tomato plants were subjected to continuous flooding stress of different durations, 0, 3, 6, 9 and 12 days. Earthen pots with healthy tomato plants were placed inside a larger concrete chamber and irrigated with tap water so that the waterlogging depth was maintained within 4-5 cm throughout the experimental period. Morphological parameters recorded include, plant height, number of leaves, stem base diameter, leaf area, dead plant %, days to flowering and number of fruits per plant. Pusharubi cultivar was heavily affected to the deleterious effect of waterlogging on all the parameters studied. Therefore Pusharubi genotype can be treated as waterlogging sensitive genotype. For all these reasons Pusharubi may not be recommended for cultivation in low land areas or where water stagnation is prominent. This experiment identified some agronomic traits associated with flood-tolerance for vegetable crop.

End Date: 00-12-2018

Program Area: Crop-Soil-Water Management

Commodity: Waterlogging, Tomato

Objectives:

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

Methodology:

An experiment was conducted at Jute Agriculture Experimental Station, BJRI, Manikganj during the period from September to December, 2018 in pot culture to find out the waterlogging effect on growth and yield of tomato. The crop was sown on 18^th September, 2018. Seeds of tomato cultivars were surface sterilized by keeping the seeds in 1% HgCl₂ solution for 2 min, followed by rinsing thoroughly with distilled water. Twenty-five seeds were sown per pot (15 inches in height and 16 inches in diameter) containing 40 kg soil. The atmospheric temperature fluctuated within a range of 29-31°C at day and 18-27°C at night. The relative humidity fluctuated between 71 and 83% at day and night, respectively. Waterlogging induced at 30 DAG (Days after germination). A tomato variety `Pusharubi’ with five different i.e. 0, 3, 6, 9 and 12 days of waterlogging were used as treatments. Waterlogging depth was 4-5cm from the base of the plant. Crop was harvested at the period of horticultural maturity. Completely Randomized Design (CRD) with a single factor and three replications were used in this experiment. There were five plants per pot and 3 pots were considered as a replication. Each replication contains 15 plants. The collected data on different growth and yield related characters were subjected to statistical analysis following ANOVA technique. Differences among treatment means were adjusted by Duncan’s Multiple Range Test with the help of a computer based statistical package program MSTAT-C (Gomez and Gomez, 1984).

Achievement/Findings:

The findings of this work divulged that, flooding put forth an immense jolt on the growth, development and yield of the treated tomato genotype Pusharubi. Hence it should not be put forward to cultivate in the flood prone areas. The current knowledge of the morpho-physiological basis of flood tolerance, coupled with breeding approaches followed by genetic engineering of tomatoes may lead to a more complete understanding to experiencing a notable success in enhancing waterlogging stress tolerance.
