Abstract
The present investigation entitled “Effect of foliar application of boron, zinc and iron on growth and yield of gynoecious cucumber var. Kian” was conducted during Kharif, 2014 under naturally ventilated polyhouse at the College of Horticulture and Forestry, Jhalawar. The experiment comprised of twenty seven treatment combinations consisting of three levels of boron (0, 20 and 40 ppm), three levels of zinc (0, 20 and 40 ppm) and three levels of iron (0, 40 and 80 ppm) in Factorial Randomized Block Design with three replications. The treatments were sprayed twice at 25 and 45 DAS.
The observations were recorded on 14 growth and yield attributes namely i.e. days to anthesis of first female flower, node number at which first female flower appeared, number of branches per plant at 45 and 90 DAS, vine length at 60 DAS and final harvest, chlorophyll (a) content of leaves at 30, 60 and 90 DAS (mg/100gm), chlorophyll (b) content of leaves at 30, 60 and 90 DAS (mg/100gm), number of aborted flower (%), fruit length (cm), fruit diameter (cm), average fruit weight (gm), volume of fruit (cc), number of fruits per plant, days to maturity of fruit and yield per plant (kg), Higher level micronutrients influenced significantly the most of the characters when they were applied alone or in combinations.
Application of micronutrients (Boron, Zinc and Iron) at their high concentration influenced significantly the most of the growth and yield attributes when they were used alone or in combination. The treatment combination B2Zn2Fe2 (Boron at 40 ppm + Zinc at 40 ppm + Iron at 80 ppm) was found economical as it gave maximum yield (5.62 kg./plant), maximum net return ( 498.67/m2) and B : C ratio (4.71). Further, this treatment increased the fruit length (14.10 cm), fruit diameter (3.40 cm), average fruit weight (130.33g), volume of fruit (135.43cc), number of fruits per plant (43.13), reduced the number of days required to fruit maturity (38.83) and number of aborted flower (68.24 %) over control.
