Effect of laser radiation on Growth and Yield parameters of Cucumber Plant (Cucumis sativus L.) var. Dalia

Abstract

This study was conducted to evaluate the efficiency of laser radiation He-Ne ,and study there effect in stimulation the growth and production of cucumber crop during the season 2014-2015. The experiment carried out under a nursery condition at the Horticulture and Forestry unit of Agricultural Directorate, Najaf, according to the Complete Randomized Design (C.R.D.) with three replicates for each treatment. The cucumber seed were exposed to laser radiation for (1, 2 and 3) minutes. The mean was compared by Least Significant Differences (LSD) at the level of probability of 0.05. The results showed that exposing the seeds for laser option caused a significant increased in all growth indicators studied, compared with the control treatment, seeds exposed to laser radiation for 3 minutes outperformed on the rest of the treatment in the mean of plant height, leaf area, shoot weight , root weight and total yield 140.22 cm, 1.722 m,.88.37 g ,0.63 g and 1143.6kg respectively, while control treatment gave 109.78 cm , 1.511 m , 49.77 g , 0.21 g and 808.8 kg respectively
