Abstract: 

The research was conducted at Al-Jammasah Research Station in Tartous in 2019 to study the effect of pruning and spraying with some organic extracts on the productivity and quality of fruits and marketable seeds of L2 tomato line. Factorial experiments using randomized complete block design with three replications were implemented. Results indicated that the combinatorial treatments two stems pruning with Amalgerol spraying, followed by two stems pruning with Volomene spraying significantly outperformed all the other treatments in the productivity trait. Results also showed the superiority of the one stem pruning with Amalgerol spraying treatment over all of the other treatments in the average fruit weight, number of marketable seeds and weight of a thousand seeds. The two stems pruning without spraying treatment was significantly superior to the number of fruits per plant. The treatment of spraying with Amalgerol was significantly superior to the Volomene spraying and Control treatments in all the studied traits, except for the number of fruits per plant, where the control treatment outperformed the two extracts spraying treatments. The pruned plants on one stem showed significant superiority over the two stems in average fruit weight, number of marketable seeds and 1000 seeds weight. The pruned plants on two stems were significantly superior in the plant productivity and number of fruits per plant.

Keywords: Tomato, organic extracts, stem pruning, productivity, seed quality.
