Cabbage growth and yield as influenced by irrigation methods in old valley [electronic resource].

Includes references.

In order to develop techniques that environment temperature in Gemmiza Agricultural Research Station during summer season 2010. An experiment carried out the yield of cabbage was maintained at high level by use of irrigation. Yield in winter is bigger than in summer, so we applied sprinkler irrigation plus for both furrow and drip irrigation to make the same conditions in the summer season to be like condition rain fall to overcome temperature raising in the summer. Improve some plant characteristics due to using sprinkler plus furrow irrigation increasing by 13 .9 , 8.6, 6.7, 25,33.3 and 11.11 % respectively. Compared with furrow irrigation for mean head diameter, mean head height, plant height, root length(cm) , mean head weight and fresh root weight (kg). The increasing in drip plus sprinkler 19.15 ,24.4,33.7,42.8, 76.8 and 71.4 % compared by drip irrigation. The yield increase by 53.8 %in furrow plus sprinkler compared furrow irrigation The increasing in drip plus sprinkler about 77 % compared with drip irrigation . Effect of fertilizer on some x characteristics on mean head diameter; mean head height; plant height; root length (cm) mean head weight; and fresh root weight (kg) due to use I ton /fed compost were increased by 4.9, 8.33, 17.3, 27.5, 58.6 and 21.0% respectively compared with using 0.5 ton compost /fed. Effect of fertilizer on yield by using 1 ton compost / fed increased the yield by 58.3 % comparing with using 0.5 ton /fed. Effect of irrigation interval on mean head diameter; mean head height; plant height and root length(cm) , mean head weight and fresh root weight (kg) showed that increasing of 2.5 , 5.5 15.8, 2.4, 10.0 ,and 25 % respectively compared by drip with interval of three days . for the treatment of drip plus sprinkler irrigation with daily irrigation the increasing were 63.6, 12.6, 0.0, 1.8,3.3 and 10.0 % respectively Effect of irrigation interval on yield increase by 2.4 % For drip interval of three days, Also when applied drip plus sprinkler daily, the yield increased by 63.6 % compared with drip plus sprinkler every three days.
