Study on Okra (Abelmoschus esculentus L.) Response to Salt Stress Environment under Kabul Climatic Conditions, Afghanistan

Abstract − The research was conducted to examine the effects of saline-irrigation water on growth and fresh pod weight okra (Abelmoschus esculentus L.) under climatic conditions Kabul province, Af-ghanistan. This study consisted four treatments having different salinity levels irrigation water, (T1:0.0mM, T2:5mM, T3:10mM, T4:20mM), which were applied throughout growing season in plastic pots with a randomized complete block design. Results showed that saline caused significant reduction germination seeds (in T1:98% germination, T4: 53% germination), leaf length T1:9.17 cm, T4:6.8cm length), shoot height T1:15.43cm, 13.87cm Shoot height) root T1:15.37cm, T4:8.7cm length). Okra plants grown salt stress significantly decline yield as compared control treatment. While 6904kg/ha obtained treatment (T1), 6696kg/ha, 4772kg/ha, 3100kg/ha T2, T3 T4 applications, respectively. Water use efficiency maximum minimum level 20mM. A value 13.08kg/ha/mm computed for 5.87kg/ha/mm 20mM, 5mM 10mM 12.68kg/ha/mm 9.04kg/ha/mm As result, parameters decreased increasing concentration ECiw (electrical conductivity water). Salinity adversely affected morphological physiological characteristics okra.
