EFFECT OF SALINITY ON GROWTH AND MINERAL COMPOSITION OF CUCUMBER, SNAKE
MELON AND PEANUT S. M. ALAM, S, AHMED AND S.S. M. NAQVI Abstract: Sand and gravel culture techniques were used to study the effect of irrigation with saline nutrient solution on dry matter yield and nutrient content of leaves and stems of cucumber, snake melon and peanut. Dry matter yield of cucumber and snake melon decreased at high salinity level. There was no effect of salinity upto 4000 ppm on the dry weight of peanut. Maximum fruit yield of snake melon was recorded at 2000 ppm salinity level while reproductive growth of cucumber and peanut was severely affected. Salinity caused accumulation of Na in leaf and stem of test plants where K, Ca, Mg,Fe and Mn significantly decreased with increasing salinity levels in all plant parts.
