Evaluation of Soil Temperature under Mulches and Garlic Extract on Yield of Cucumber (Cucumis sativus L.) in Greenhouse Conditions

Abstract

The experiment was conducted during the growth season of autumn to spring at the desert Najaf on plant cucumber Toshika, 2012-2013 and the results showed that the highest heat accumulation in soil produced from black polyethylene, followed by transparent polyethylene, rice residues and control treatments (1705, 1583, 1428, and 1194) respectively. Black polyethylene gave a significant effect as compare with other mulch treatments on the yield and its component characteristics (fruits of number and yield). The garlic extract spray gave a significant effect on the yield and its components. The concentration 5 ml.L-1 gave the highest means of the most yield and its components, fruit number, and green house productivity as compared with a season. The interaction results between mulches and garlic extract spray showed that there were a significant difference on yield and its components for both season. The interaction of black polyethylene with 5 ml.L-1 garlic extract gave the highest mean of yield and its components in compared to control.
