Abstract :
Irrigation plays a major role in the growth and production of indigo plant. Drought tolerant and resistant plants are mostly selected for culture in irrigated and semi-irrigated fields for better production. Indigo plant is a resistant plant to drought for warm climate. This study was carried out to assess the drought stress and nitrogen on yield and some physiological features of the Indigo plant in Bihar in 2018. The study consists of randomized complete block design with three replications and irrigation was done after depletion of 90% and 50% of field capacity. Results revealed that no stress + 130 kg nitrogen ha-1 increased plant height, No. of Shoot/plant and No. Pod/plants of indigo as 72.80 cm, 8.90 cm and 383 cm, respectively. Water deficit stress had different effects on plants. Results showed that drought stress + 50 kg nitrogen ha-1 and no stress + 130 kg nitrogen ha-1 increased the No. of seed/pod of the plant at 5.30 kg/h. The most grain yield of about 226 kg ha-1 was obtained from the highest density in the optimum irrigation treatment.
