Effect of foliar application of chelated calcium and boron on growth and yield of strawberry (Fragaria ananassa Duch.) CV. Festival

Abstract

This study was carried out in plastic house of research and Agriculture experiments station of Agriculture college at Kirkuk university through 2016/2017 growing season to study the effects of foliar application of chelated calcium with three concentrations (0, 50, 100 ) mg L-1 and boron (0, 10, 20 ) mg L-1 on vegetative growth characters and yield of Strawberry cv. Festival. The experiment was arranged in factorial experiment in randomized complete block design with three replicaters and five plants for each experimental unit. The obtained results statistically analyzed using package of (SAS V 9.0) program and using Duncan test at 0.5% probability to comparing the means. Folia application of mg/L100 chelated calcium led to significantly increased in vegetative growth parameters (leaf area, number of leaves, leaf chlorophyll contents and vegetative growth dry weight), weight which reaching ( 33.49 ,47.06 , 39.97 , 19.94 ) , respectively as compared as compared with control treatment , while foliar calcium at 100 mg/L gave the significant increasing for fruit size and weight which were 18.79 cm3 and 12.11 gm, respectively, at the same time all other yield characters did not affected. The foliar 20mg/L Boron led to significantly increased in vegetative growth parameters above ,As well led to significant increasing in fruit number and size, mean yield per plant and yield for unit area as compared with control treatment, while the mean fruit weight character did not affected with Boron treatment. The interaction effects of two factors clearly significantly affected on all parameters, it was found that 100mg/L calcium and 20mg/L boron treatment was significant as compared with control on vegetative growth characters and yield.
