The field experiment was conducted at college farm, CAET, NAU, Dediapada, during rabi season 2017-18. The experiment was laid out in randomized block design with four replications, keeping five treatments of T1- Drip irrigation with 0.6 PEF, T2 - Drip irrigation with 0.6 PEF, Drip + Black Plastic Mulch 50 µ with (56 % coverage), T3 - Drip irrigation with 0.6 PEF, Drip + sugarcane trash mulch @ 5 t/ha with (56 % coverage), T4 - surface irrigation IW/CPE: 1, 60 mm depth + sugarcane trash mulch @ 5 t/ha (56 % coverage) and T5 - surface irrigation IW/CPE: 1 (control) with 60 mm depth. Growing of rabi pigeonpea resulted significantly higher yield attribute and biological yields in the treatment 0.6 PEF through drip irrigation with sugarcane trash mulch @ 5 t/ha. Among mulch treatments, 0.6 PEF through drip with sugarcane trash mulch @ 5 t/ha was found to be significantly superior over other treatments with higher plant height at harvest (182.66 cm), leaf area index (0.88), stem girth (16.46 mm), root length and spread (40.05 and 27.38 cm), number of pod per plant (273.26), number of seed per plant (981.89), number of seed per pod (3.59), pod yield per plant (147.71 g), grain yield per plant (100.63) and 100 seed weight (11.20 g). The grain yield registered under treatment T3 and T4 were 80.66 % and 50.87 % higher than surface (control). Black plastic mulch was found more effective in reducing soil moisture loss followed by organic mulch compared to no mulch which was associated with high moisture depletion and higher soil temperature. | EXCELLENT PUBLISHERS International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 8 Number 07 2019 Journal homepage http www.ijcmas.com Original Research Article https doi.org 10.20546 ijcmas.2019.807.006 Effect of Pigeonpea to Irrigation and Mulch Regime M.A. Solanki1 A.L.
