Abstract:
A field experiment was conducted during rabi season of 2017-18 and 2018-19 at Saline Water Scheme, Ag College Farm Campus, Bapatla on sandy loam soil to evaluate the performance of marigold, chrysanthemum and tulasi crops with saline water through drip irrigation system. The experiment was laid out in split plot design with three replications. The crops viz, marigold, chrysanthemum and tulasi were considered as main treatments and five salinity levels of irrigation water viz, BAW (0.6 dSm^-1), 2, 4, 6 and 8 dSm^-1 were considered as sub treatments. The results revealed that significantly maximum number of flowers 148 and 158.6 in marigold crop, 95 and 96.8 number of flowers in chrysanthemum crop was recorded with BAW (EC 0.6 dSm^-1) treatment among the different levels of saline water through drip irrigation, respectively. Increased salinity levels caused yield reduction by % 69.6, 71.8 and 64.2 and 68.1% in marigold and chrysanthemum crops when irrigated with salinity level of 8 dSm^-1. In Tulasi crop 9220 and 8645 kg ha^-1 biomass yield was recorded irrigated with salinity level of 0.6 dSm^-1.
