Response of nitrogen and row spacing on quality and economics of Onion cv. N-53 under Arid environment

Abstract

An experiment was conducted to investigate the response of nitrogen and row spacing on quality parameters and  economics of onion cv. N-53 under arid environment at Research Farm, College of Agriculture (Swami Keshwanand  Rajasthan Agricultural University), Bikaner. The experiment was laid out in a Randomized Block Design with five levels  -1 of Nitrogen viz. 0, 50, 100, 150 and 200 kg ha and three levels of spacing 10, 15 and 20 cm. The result indicated that the  statistically maximum number of leaves (8.36 and 803), volume of bulb (54.89 cc and 51.70 cc), diameter of bulb(4.75 cm  and 4.68 cm), weight of bulb (49.57 g and 45.77 g), allyl-propyl disulphide (6.29 mg/100g and 6.21 mg/100g) and nitrogen  -1 content in leaves (0.953% and 0.959%) and bulb (1.40% and 1.35%) were recorded with application of 150 kg nitrogen ha and 15 cm row spacing, respectively. Whereas, chlorophyll content in leaves (1.58 mg/g and 1.47 mg/g) was recorded  -1 maximum with 200 kg nitrogen ha and 15 cm row spacing, respectively. B:C ratio (2.08 and 2.17) was observed highest  -1 in 150 kg nitrogen ha and 15 cm row spacing, respectively.
