RESPONSE OF TOMATO (Lycoperciew, esculeittuin L.) TO SALINITY IN HYDROPONIC STUDY

Abstract

The research work presented in this thesis was conducled to evaluate the performance of loniato under the different levels of salinity (NaCl) in the hydrophonic culture house of Baneladesh Agricultural Research Institute (I3ARI). llorticulwre Research Centre. (iazipur. during the period of November 2011 to Febniarv 2012. The experiment was laid out in Completely Randomized Design (CRD) with tour replications. There were five treatment combinations Salinity levels (T1 -o dSm' . f74 dSm . 1' S dSm" . l.= 12 dSni' and Tç-lb dSm5, Results revealed that l (control) showed the best performance in terms of growth, yield and yield contributing attribtttes, plant physiological parameter, plant nutrient concentration. The maximum ntuiiber of Fruits (19 plant ) and the highest fruit weight plant (1.60 kg) were Ihund train the control treatment. This experiment showed differtnt impact of each nutrient and its interactions on tomato plant. The experiment showed that at 16 dSm' salinity level highest Na and Cl uptake itdueed the uptake of K and at 0 dSm" salinity when Na and ('I ions were low in water. K uptake increased. Salinity had a greater impact on stomata resistance and chlorophyll content of plants. The experiment also showed that at control treatment leaf area plani'. total chlorophvl I content and plant dry matter was highest but stomata resistance was minimum and on the oilier hand. at 16 dSm 1 salinity level these Factors showed fully reverse. I lowever, the overall impact of salinity had negative impact on growth and yield oftornato plant.
