Abstract
In current years, water quality of river Yamuna has degraded drastically due to rapid socio-economic development and various anthropogenic activities. As per Central Pollution Control Board (CPCB) the water quality of river Yamuna is of category E which makes it fit only for irrigation, industrial cooling and controlled waste disposal. Current study revealed the effect of Yamuna water on cultivars of two economically important crop legumes, that is Vigna radiata (PUSA1431 and PUSA9531) and Vigna mungo (KU6 and MASH114) collected from PUSA (Pulse laboratory). Water samples were collected from two locations one is entry point of Yamuna in Delhi, that is stretch of Wazirabad and one is exit point from Delhi, that is Okhla route. Different water quality parameters, such as pH, colour and odour have been recorded while collection, total dissolved solids (TDS), total suspended solids (TSS) and heavy metals have also, been determined. Dissolved oxygen (DO) and biochemical oxygen demand (BOD) of water samples have been determined by Winkler’s method and dilution method, respectively. Effect of different water samples on cultivars of Vigna radiata and Vigna mungo were determined by observing different growth parameters including percentage germination, length of roots and shoots, weight of fresh and dried seedlings at different time intervals.
