Performance of Different Varieties of Cauliflower (Brassica Oleracea Var. Botrytis) Under Different Level of Nitrogen Application in Ultisols of Lamjung Nepal
Journal Title: World Journal of Agriculture and Soil Science - Year 2018, Vol 1, Issue 2
Abstract
Nitrogen (N) is one of the major determining nutrients for growth and development of cauliflower (Brassica oleracea L. var. botrytis). N deficiency in cauliflower field is becoming a major problem in Nepal. Soil application of appropriate amount of N can be an effective way to increase the qualitative and quantitative growth parameter of cauliflower. A field experiment was carried out in ultisols at Sundarbazar ward no.7 Taarkutar village of Lamjung district Nepal, during September 2017 to February 2018 to assess the response of five level of soil application of nitrogen (0 kgha-1, 80 kgha-1, 100 kgha-1, 120 kgha-1 and 140 kgha-1) on three genotypes of cauliflower (Kathmandu local, Snow mystique and Snow grace). The experiment was laid out in Randomized Complete Block Design consisting of 15 treatments with 3 replications. Half dose of N with full dose of P, K and B were applied as basal dose and remaining dose of N were applied in two split doses at 30 DAT and 60 DAT and Molybdenum (75ppm) was applied in 3 split doses i.e. 20 DAT, 40DAT and 60 DAT. The effects were observed over leaf chlorophyll content (30DAT and 60 DAT), curd weight, root weight and total biological yield. The findings of this study showed that the soil application of N showed significant result at leaf chlorophyll content and curd weight of cauliflower. Highest amount of leaf chlorophyll content and highest curd weight (0.84kg) was recorded at 120kgha-1 nitrogen level as compared to other level of nitrogen and Snow mystique had significantly highest chlorophyll content and curd weight (0.73 kg) over other varieties of cauliflower.
