A study of the effect of biofertilizers containing amino acid on the yield and growth traits of cucumber (Cucumis sativus ) var.Royal

Today, by reason of the irregular use of chemical fertilizers and its detrimental effects on the human and soil health, humans make use of biofertilizers and organisms to provide nutrition requirement of the plants. The purpose of this study, improvement nutritional conditions of cucumber and production with maximum yield by using biofertilizers so if possible recommend this biofertilizers as replacement of current chemical fertilizers. an experiment was conducted in 2011 in Jiroft as a factorial experiment with completely randomized block design in three replications on the cucumber (Cucumis sativus) var. Royal. Treatments were included three concentrations 0(control), 2000 and 4000 ppm of biofertilizers including humifrote, fosnutren and kadostim via foliar application in 3 stages. The results indicated that the effect of bio fertilizers on fruit length, yield per bush, number of flower and plant length at 1% probability and on yield per m2 was significant at 5% probability. Effect of biofertilizers on the traits like number of fruit, fruit diameter, weight of single fruit, length of internode and diameter of stem was not significant. The best treatment in present study was humifrote at concentration 4000 ppm that lead to most yield per bush and yield per m2.
