Effect of Variety and Planting Date on Growth & Yield of Cucumber(Cucumis sativus L.) Under Unheated Plastic House Condition

Abstract

The experiment has been done in plastic house complex - college of Agriculture - Tikrit University (2013 - 2014). It includes (16) treatment consists of overlap among four varieties of cucumber (Datis, Silyon, Reem, Sayaff) and four dates of planting (30/12/2013, 15/1/2014, 1/2/2014, 15/2/2014). The experiment has been designed according to (split plot design) by rando sectors (R.C.B.D) and three replicate in order to study the impact of variety and date of planting on growth and yield of cucumber under unheated plastic house condition. More important results can be summarized as follows: Silyon variety is significantly by weight, length of fruit and production of one plant. Datis variety is significantly by number of fruits per plant and rigidity ration of fruit. Sayaff variety is significantly by T.S.S. no difference between Datis, Silyon and Sayaff for diameter of fruit while Reem variety gave a low value. The first date of planting significantly by weight, length, rigidity, and T.S.S of fruit compare the other date of planting. The second date of planting significantly by number of fruits per plant and production of one plant while no difference between planting dates by diameter of fruit. The overlap between Silyon variety and second date of planting significantly of number of fruits per plant and production of one plant, the overlap between Silyon variety and fourth date of planting significantly of length of fruit. Sayaff variety is with first date of planting significantly for fruit weight and rigidity of fruit. Sayaff variety is with second date of planting significantly for T.S.S comparing it with another result. Reem Variety is with fourth date of planting significantly for diameter of fruit.
