Effect of Irrigation Level and Nitrogen Levels on Economics, Quality and Water Productivity of Garden Cress (Lepidium sativum L.)

Abstract

A field experiment was conducted at krishi vigyan kendra, Sawaimadhopur, Rajasthan in two consecutive years of 2018-19 and 2019-20 on “Effect of irrigation level and nitrogen levels on economics, quality and water productivity of chandrasur (L. sativum)”. The highest economics net return was found with three irrigations [25, 50 & 75 days after sowing (DAS)] I3  (57517 Rs ha-1) which was at par with I2 with two irrigations (25 & 50 DAS) in the pooled data of both years. Highest benefit-cost (B/C) ratio was also found under three irrigations (25, 50 & 75 DAS) I3 (2.60) which was at par with (I2) two irrigations (25 & 50 DAS) in the pooled data of both years. Highest net return and B/C ratio was found with application of 80 Kg N ha-1 (57628 Rs ha-1) and (2.65) which was at par with 60 Kg N ha-1. In terms of oil yield Kg ha-1 highest oil yield was found with (I2) two irrigations (25 & 50 DAS) and 60 Kg N ha-1. Water productivity (kg m-3) was found lowest in the treatment (25, 50 & 75DAS) (I3) and 80 Kg N ha-1 which was at par with (I2) two irrigations (25 & 50 DAS) and 60 Kg N ha-1 .
