RESUMEN
A field experiment was conducted at Krishi Vigyan kendra, Sawaimadhopur, Rajasthan, India in two consecutive years during 2018-19 and 2019-20 on Zone III –B of Rajasthan, India. In this experiment was performed in randomized block design which includes four treatments of weed control i.e. weedy check (T1), Hand weeding at 25 DAS (T2), Hand weeding at 25 & 45 DAS (T3), Pre emergence application of Pendimethaline @ 1.0 kg a.i. ha-1 (T4) and replicated five times. Results revealed that Weed Density (no m-2) 60 days after sowing, Dry weight (kg ha-1) 60 days after sowing, weed control efficiency (%) and weed index found lowest in two hand weeding at 25 and 45 days after sowing fb Pre emergence application of Pendimethaline @ 1.0 kg a.i. ha-1 (T4) during both the years during 2018-19 and 2019-20, respectively. Highest seed yield (2341 kg ha-1) and (2431 kg ha-1) was found under two hand weeding (25 & 45 days after sowing) during 2018-19 and 2019-20 respectively.
RESUMEN
The present study was carried out to investigate the effect of irrigation and nitrogen levels on growth and yield of Chandrasur (Lepidium sativum Linn.) in two consecutive years Rabi 2018-19 and Rabi 2019-20 at Krishi Vigyan Kendra, Sawaimadhopur, Rajasthan. Results revealed that higher yield attributes No of branches plant-1, Fresh weight at harvest (g plant-1), 1000 seed weight (g), plant height (cm) were found significantly higher under three irrigation (25, 50 and 75 Days After Sowing) which was at par with two irrigations (25 & 50 Days After Sowing (DAS) and with 80 kg of N ha-1 which was at par with 60 kg N ha-1. Under different level of irrigations application of three irrigation (25, 50 & 75 Days After Sowing (DAS) found higher seed yield (1593.34 kg ha-1) which remained at par with two irrigation (25 & 50 DAS) compared to (one irrigation at 25 Days After Sowing), respectively. In sub plot treatments of different nitrogen levels Application of 80 kg of N ha-1 resulted in highest yield (1586 kg ha-1) which was statistically at par with 60 kg of N ha-1 as compared to 40 & 20 kg N ha-1 respectively.
