Onion (Allium cepa) is one of the most important bulb crops in India, which plays a major role in supplementing the Income of small and marginal farmers of different district in Madhya Pradesh. One of the major constraints of Kharif onion farming is poor nursery and low productivity due to non adoption of recommended package of practices and improved verities. To replace this anomaly, National Horticultural Research and Development Foundation, Indore (M.P.) had conducted TDTD (Technology dissemination through demonstration) under National Horticulture Mission, Govt. of India, at adopted farmers’ fields. Cultivation practices comprised under TDTD viz., use of improved variety/season specific, nursery raising, soil/seed treatment, transplanting, fertilizer application and control of purple blotch disease, showed that percentage increase in the yield of onion ranged from 31.07% to 36.40% over local check during the course of study from 2012-13 to 2016-17. The technology gap of 6.2 q/ha during 2016-17 from 27.6 q/ha at the initial stage of study (2012-13) shows the gap in demonstration yield over potential yield, but the above gap reduced subsequently in the following years.Keywords

Analysis of variability carried out for ten characters in sixteen diverse genotypes of nigella (Nigella sativa L.) revealed high genotypic and phenotypic co-efficient of variations for secondary branches per plant, number of grains per fruit, number of fruits per plant, length of fruit (cm) and width of fruit (cm). Heritability estimates were high for number of grains per fruit (0.86), number of fruit per plant (0.78), length of fruit (0.64), days to maturity (0.59), number of secondary branches per plant (0.56) and yield per plant (0.47). Higher genetic advance as percentage of mean was recorded for number of grains per fruit (46.11%), number of secondary branches per plant (43.99%), number of fruits per plant (39.65%), yield per plant (24.49%), length of fruit (24.12%) and indicating additive gene effect. Quantitative traits like days to maturity, number of secondary branches per plant, number of grains per fruit and number of grains per fruit exhibited wide range of variability (134.33-143.00) maximum genotypic co-efficient of variability (29.53), maximum phenotypic co-efficient of variability (22.18), broad sense heritability (0.86) and gene gain (46.11).Keywords
