Effect of seed priming and foliar spray of boron, molybdenum on pigeonpea pea (Cajanus cajan L.)

Abstract

A field experiment entitled Effect of seed priming and foliar spray of boron, molybdenum on pigeonpea pea (Cajanus cajan L.) was conducted during Kharif seasons of 2015 & 2016 at Department of Crop Physiology, C.S. Azad University of Agriculture & Technology, Kanpur to see the effect of seed priming and foliar spray of boron, molybdenum on growth characters, yield attributes and yield of pigeonpea pea (Cajanus cajan L.). The treatments comprised 8 treatments viz. control (dry seed), water soaked seed, seed soaking with boron (0.2%), seed soaking with molybdenum (0.02%), foliar spray of water, foliar spray of boron (0.2%), foliar spray of molybdemn (0.02%), seed soaking + fohiar spray of boron and seed soaking + foliar spray of molybdem (0.02% and 0.05%). The pigeonpea variety UPAS 120 sown in Randomized Block Design with three replications. Observations were recorded on growth yield attributing characters and yield of crop. Results revealed that by seed soaking + foliar spray of molybdenum @ 0.02% at 25 DAS + 0.85% at 45 DAS recorded significantly higher seed yield i.e. 1892.00 & 2005.00 ka ha-1 as well as numerically highest relative water content in leaf (90.08% & 86.7%), leaf chlorophyll intensity (64.30% & 64.10%) during 2015 and 2016, respectively. The maximum net income Rs. 54802 and Rs. 57772 per hectare and B:C ratio 2.24 and 2.31 recorded with the same treatment during 2015 and 2016, respectively, compared to control treatment.
