Quantifying Response of Irrigation and Anti-Transpirants on Quality, Water Use Efficiency and Economics of Indian Mustard (Brassica juncea L.) Czern & Coss

The present investigation was carried out during 2017–18 and 2018–19 at Regional Research Station, Bawal to study the effect of irrigation regimes and anti-transpirants on quality, WUE and economics of Indian mustard. The experiment was laid out in spilt plot design with three irrigation regimes (control, one irrigation at 40 DAS and two irrigations at 40 and 75 DAS) and two varieties (RH-725 and RH-749) in main plots, whereas, anti-transpirants (Control, PMA @ 250 ppm, 6 % kaolin and PMA @ 250 ppm + 6% kaolin at 45 and 90 DAS) in sub plots. The significantly higher oil content and oil yield, maximum consumptive use of water (CU), water use efficiency (WUE), gross returns (GR), net returns (NR), B-C ratio as well as net income per day (NIPD) were in crop irrigated at 40 and 75 DAS. In anti-transpirants, highest oil yield, CU, WUE, gross return and net returns, B-C ratio and net income per day (NIPD) were with application of PMA @ 250 ppm + 6% kaolin at 45 and 90 DAS as compared to control but it was statistically at par with application of kaolin 6 % at 45 and 90 DAS t. Variety RH-749 performed better over to RH-725 with respect to the yield, CU, WUE and economic returns. However, varieties did not exhibit a significant influence on the seed oil and glucosinolate content.
