mpact of distillery wastewater on some of the growth parameters of Pisum sativum L. var. FPP11

In developing countries like India wastewater fertigation for crop cultivation is a regular practice. Effluents from various industries are considered as the main industrial pollutants containing organic and inorganic compounds. The increasing agricultural reuse of treated effluent serves goals such as promoting sustainable agriculture, preserving scare water resources and maintaining environmental quality. The wastewaters being used include both untreated and treated, although the former predominates the later. The present experiment was aimed to investigate the effect of tap water (clean water), primary treated and secondary treated distillery wastewater on various growth parameters i.e. (root length, shoot length, seedling length, fresh root weight, fresh shoot weight, fresh seedling weight, root shoot ratio) and various stress indices i.e. Shoot Length Stress Tolerance Index (SLSTI), Root Length Stress Tolerance Index (RLSTI), Root Fresh Weight Stress Tolerance Index (RFSTI), Shoot Fresh Weight Stress Tolerance Index (SFSTI) of Pisum sativum L. var. FPP11. The results depicted that the maximum values for all growth parameters mentioned above were observed in seedlings treated with tap water (control Set-1) which was followed by Set-3 treated with secondary treated wastewater and minimum was shown by seedlings treated with primary treated distillery wastewater i.e. (Set 2). Maximum stress tolerance was shown by Set 1(Control set) i.e. (100%) which was followed by Set 3 i.e. (Secondary treated wastewater) and minimum stress tolerance for all the indices was shown by Set 2 i.e. (Primary treated wastewater).
