Azad University of Agriculture & Technology, Kanpur, Uttar Pradesh, India Effect of seed priming and foliar spray of boron, molybdenum on pigeonpea pea ( Cajanus cajan L.) Dr. CB Verma, Dr. Videsh Kumar Verma, Dr. Ram Pyare and Dr. Dhananjai Singh 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. Keywords: Pigeonpea, boron, molybdenum, seed priming, foliar spray Introduction Pulses are one of the important segments of Indian Agriculture after cereals and oil seeds. The split grains of the pulses called dal are excellent source of higher quality protein, essential amino acids, fatty acids, fibers, minerals and vitamins. Pulses also render improvement in soil health by enriching its N status, long term fertility and sustainability of the cropping systems. Pigeonpea need some macro and micronutrient for its normal growth. Some of these elements play an important role in the process of Rhizobium symbiosis; molybdenum is a constituent of the nitrogenase enzyme and every bacterium which fixes nitrogen needs molybdemn during the fixation process. Molybdenum has a positive effect on yield quality and nodule forming in legume crops. Boron is a non metal micronutrient that is required for normal growth and development of the plant. It is an immobile micronutrient functions on cell wall strength and development, fruit and seed development, transport of sugar, development of hormone, membrane function, ribonuclic acid (RNA) metabolism, cell devison, respiration and Indol Acitic Acid (IAA) metabolism. (Goldbach HE et al., 2001) [4] . Ali and Mishra (2001) [3] found a significant response when foliar application of boron were carried out. The highest yield was obtained when the boron application was carried out. Seed priming is also an important physiological seed enhancement. It provides a low-cost practical solution to seed germination under stress conditions. Abiotic stress like variation in temprature and inadequate moisture during sowing time results in poor germination and poor plant stand leading to fall in crop yields. To harvest the full genetic potential, seed must germinate and seedling emerge quickly and uniformly, the process of seed priming performed. Thus keeping all above poitns in view the present investigation was formulated and conducted. Material and Methods The field experiments were conducted during two Kharif seasons of 2015 and 2016 at department of crop physiology, Chandra Shekhar Azad University of Agriculture & Technology, Kanpur, Uttar Pradesh, India under rainfed condition.
