SOME AGRONOMICAL PRACTICES FOR IMPROVING TOMATO (Lycopersicon esculentum, Mill) PRODUCTIVITY UNDER HIGH TEMPERATURE CONDITIONS.
Two field experiments were conducted at EL-Baramon Research Station, Dakahlia Governorate, Egypt. during summer seasons of 2007 and 2008 to study the effect of some foliar applications, i.e., calcium at 2000 mg/L, magnesium at 2000 mg/L, zinc at 100 mg/L, boron at 50 mg/L, selenium at 5o mg/L + vitamin E at 150 mg/L, yeast extract at 100 ml/L and salicylic acid at 100 mg/L on vegetative growth, flowering and fruit yield of Castle Rock and Super Strain-B tomato cvs under high temperature conditions. Seedlings were transplanted on 9 th and 15 th of May in the first and the second seasons, respectively.
The results showed that Castle Rock plants had more leaves and branches, heaviest fresh and dry weight and gave the best flowering parameters, i.e., number of clusters/plant, number of flowers/plant, fruit set percentage (%) and total fruit yield(ton/fed.) compared with Super Strain-B cultivar which had the longest plants in the two seasons. Moreover, all foliar applications (Ca, Mg, Zn, B, Se + VE, Yeast and SA) increased plant height, number of leaves and branches/plant and fresh and dry weight of leaves and increased all studied flowering parameters and total fruit yield(ton/fed.) compared to the control treatment. However, Super Strain-B plants sprayed with SA had the longest plants, while Castle Rock plants treated with SA and B gave more leaves and branches, respectively. Moreover, plants of Castle Rock sprayed with B had the most records in fresh and dry weight, fruit setting (%), number of fruits/plant and total fruit yield(ton/fed.). whereas Castle Rock plants treated with Ca had more clusters and flowers/plant.
From the obtained results it could be concluded that spraying Castle Rock cv plants with boron at 50 mg/L, calcium at 2000 mg/L, salicylic acid at 100 mg/L and selenium at concentration of 50 mg/L mixed with vitamin E at concentration of 150 mg/L as foliar application three times, i.e., 15 days after transplanting then repeated each 15 days interval improve tomato vegetative growth, flowering and fruit yield(ton/fed.)
