Study of the effect of using bumblebees and organic carbon in improving fruit set and yield of tomato under green house


Abstract in English

The experiment was carried out at Jableh region during 2012-2013 in two green houses to study the effects of using the bumble bees and organic carbon to improve flower set and yield of tomato hybrid Dalloula . The experiment included three treatments : natural pollination (control) ,flowers pollination by organic carbon, and flowers pollination by bumble bees . The first and second treatments were applied in the first green house , and the third treatment was applied in the second green house . Results showed that the bumble bees treatment produced significantly the highest percentage of flower set and yield than the other treatments . Flower set of tomato over 10 clusters was 89.8% , 83.7% , 39.2% for bumble bees treatment, organic carbon treatment, and control , respectively. The highest yield (22 kg/m2)was obtained from bumble bees treatment . Flowers pollinated by bumble bees gave fruits that looked better in shape , size and color ,and with higher weights . In the bumble bee pollinated flowers , the quality of fruits was superior for vitamin C , sugar and acidity .
