Nigella (Nigella sativa L.) is a spice crop that belongs to Ranunculaceae family. The seeds or grains resembling onion seed, are used both as spice and medicine. In Malda district of WB, this crop do not cultivated earlier time but recent 2 to 3 Years it is introduced as a new seed spices which opens new avenues for the farmers by not only the choice of crops but also improve their revenue from the land. The present investigation was carried out during rabi 2017 and 2018 in the Malda district on, optimum N and P application levels to get high yield and quality in nigella four levels of nitrogen (0, 20, 40 and 60 kg nitrogen (N) ha-1 ) and phosphorus (0, 15, 30 and 45 kg phosphorus (P)/ha. The study on application of different levels of nitrogen and phosphorus revealed that all the traits were influenced by N and P application. There was interaction effect in the traits like plant height (60, 90 DAS and at harvest), capsule yield, husk yield. N and P application levels improved the plant height, number of leaves per plant and number of branches per plant at different stages of growth. Similar response was observed in fresh and dry matter accumulation. Minimum total chlorophyll content, The yield contributing characters like capsule weight at harvest, capsule length and diameter, number of capsules, number of seeds per capsule, test weight, capsule yield per plant and grain yield per plant increased with level of application of N and generally maximum values were observed in highest N application. Similar response was observed with P application. Seed yield and stalk yield were maximum at highest N application. Seed yield was maximum with the application of phosphorus 45 and 30 kg /ha. | Effect of nitrogen and phosphorous fertilizer application on growth and yield of black cumin cultivation in Malda district (WB)
