dc.description.abstractThe present investigation entitled “Effect of growing methods and direction of sowing on seed yield and quality in bottle gourd cv. Pusa Naveen” was conducted at the Seed Production Unit farm, during kharif 2014 and laboratory observations were carried out at Division of Seeds Science and Technology, Indian Agricultural Research Institute, New Delhi. The objectives of this investigation were to study the effect of growing method and direction of sowing on growth, flowering, seed yield and quality attributes. The observations on growth, flowering, seed yield and quality characters were recorded and subjected to t-test analysis. Significant difference among the methods of growing for leaf area was observed in trailing method at 45 & 55 DAS (9576.3 cm2 &42807 cm2 ) respectively. Significantly higher vine length (4.56 m), number of leaf per vine (40.48) and leaf nodes (40.48) were recorded in trailing in comparison to traditional method at 55 DAS, while these characters were non-significant at 45 DAS. Significantly less number of days was taken for anthesis of first male flower (49.82) and female flower (54.67) in trailing. Nonsignificant differences for male flower, female flower/plant and sex ratio were observed among the trailing and traditional method of growing. The fruit development attributes i.e. fruit set, fruit developed to maturity, fruit weight, fruit length, fruit width and thickness of fruit wall was significantly higher in trailing than traditional. Similarly, results were recorded for seed yield attributes i.e. total seed/fruit (723.01), filled seed per fruit (651.88), seed yield per fruit (98.33 g), seed yield per vine (346.16 g) and seed yield per acre (410.13 kg) were significantly higher in trailing in comparison to traditional method. The seed quality attributes viz, germination percentage, root & shoot length, seedling length, seedling dry weight, vigour index I and II and embryo weight were also significantly superior in trailing method as compared to traditional method. Electrical conductivity of seed leachate and seed coat weight showed non-significant difference among the growing methods. Seed physical parameter like breadth, eccentricity and axial width showed significant difference among the growing methods. Significantly higher vine length (2.49 m), leaves per vine (25.23), leaf area (10425.17 cm2 ), primary laterals (8.13) and leaf on primary laterals (29.8) were recorded in E-W direction than N-S direction at 45 DAS. Number of leaf per vine (42.13), leaf 100 area (50792.33 cm2 ), leaf on primary laterals (81.96) and secondary laterals (5.16) were recorded significantly higher in E-W direction at 55 DAS. In E-W direction, significantly less number of days was taken for anthesis of first male flower (49.53) and female flower (53.46).Significantly more number of male flower (121.26) and less female flowers (15.53) per plant were observed in E-W direction as compare to N-S direction (102.6 and 18.63, respectively). The fruit development attributes i.e. fruit set (4.4), fruit developed to maturity (4.0), fruit weight (2.55kg), fruit length (49.89cm), fruit width (9.81cm), cavity volume (2087.6 cm3) and thickness of fruit wall (2.53cm) was significantly higher in EW direction. Similar, seed yield attributes i.e. seed yield per fruit (107.06 g), seed yield per vine (410.05 g) and seed yield per acre (423.7 kg) were significantly higher in E-W direction than N-S direction. The seed quality attributes viz, shoot length (20.89cm), seedling length (43.49cm), seedling dry weight (0.687 g), vigour index I (4247.37) and II (67.13), seed coat weight (0.8426g) and embryo weight (0.779g) were also significantly superior in E-W direction as compared to N-S direction. Electrical conductivity of seed leachate showed non-significant difference among the growing methods. Seed physical parameter like roundness, axial length, median length and median width showed significant difference among the growing methods. Keeping in view of the results recorded, it is concluded to obtained higher yield and quality the seed production of bottle gourd cv. Pusa Naveen should be organized over trailing and sowing should be done in E-W direction during Kharif season under Delhi condition.en_US
