Effect of training method on the growth and yield of some hybrid cucumber (Cucumis sativus L.) grow in the plastic house .
The experiment was conducted during the winter season 2016-2017 in Siddakheel district, Dhi Qar province, in order to study the effect of two training methods of four hybirds of cucumber planted in the plastic house on vegetative indicators, chemical components of leavs, flowering growth, yield. The experiment included eight factorial treatments which were the combination of interaction with four cucumber hybrids (Sayf F1, Silyon Rz F1, Baraa 138F1 and Rami F1) and two methods of training of cucumber plants (one stem, two stems) . The experiment was carried out according to the split plot design in R.C.B.D with three replicates,.The results analyses with least significant differences test (L.S.D) test at the probability level of 0.05Results showed that Baraa 138 F1and Silyon RZ F1 were superior to the rest hybrids Sayff in number of leaves and the hybrids Baraa 138, Sayff and Rami in the dry weight of the plant and number of flowers while the Silyon RZ Significantly higher in the content of leaves hybrid Baraa 138 F1, Rami F1 significantly surpassed in in the percentage of fruit set, weight of the furit , plant yield and length of the fruit . Rami gave a significant increase in early yield per square meter while the Rami and Baraa 138 F1 significant Surpassed in the percentage of soluble solids . Baraa 138 F1 and sayff gave a Significant in crease in vitamin C content.The breeding of hybrids in two stems was Significant increased all vegetative indicators growth and chemical components of leaves except the content of leaves of totoal chlorophyll .Also weight of the fruit , early yield per square meter and the content of the fruits of total soluble sollds .while the plants grown on the one stem gave a significant in crease in number of fruits ,length of the fruite , percentage of fruite set, the fruit content of vitamin C and the ratio of the dry matter The interaction has shown a Significant effect in most of the studied Characteristics .the hybrid plants Rami grown with two stems gave the yield per plant and early yield per square meter (1.811، 7.25) kg respectively .
