“…Regarding interaction maximum number of fruits plant -1 (38.13) was observed in with the foliar application of calcium and magnesium at the rate of 0.30% and 0.08% correspondingly. The result were similar to [18], who stated that the number of fruit plant -1 increases with application the calcium fertilizer. Due to the calcium insufficiency a known disease blossom end rot occur in tomato.…”

Deficiency of calcium and magnesium has a negative impact on plant growth and yield. In this study quantitative parameters of growth and yield in Peshawar were studied by spraying different levels of calcium and magnesium on foliage of tomato (Lycopersicum esculentum L.). Calcium chloride source was used as calcium at Ca1 (0%), Ca2 (0.15%), Ca3 (0.30%) and Ca4 (0.45%) and magnesium sulphate source was used as magnesium at Mg1 (0%), Mg2 (0.04%), Mg3 (0.08%) and Mg4 (0.12%) with 15 days interval after transplantation for a period of three months. The maximum plant height (75.78 cm), number of branches plant -1 (8.02), number of flowers cluster plant -1 (22.40), number of fruits plant -1 (33.04) and total yield (ton ha -1 ) (23.07) was observed in plants with 0.30% calcium application. Similarly, maximum plant height (72.98 cm), number of branches plant -1 (7.94), number of flowers cluster plant -1 (21.57), number of fruits plant -1 (31.01) and total yield (ton ha -1 ) (21.54) was observed in plants with 0.08% magnesium application. This study suggests that calcium and magnesium at the rate of 0.30% and 0.08 % with 15 days interval after transplantation significantly increase the yield and growth under the agro climatic and soil condition of Peshawar valley.

“…In severe pruning treatments there is high ventilation around the plants and on the other hand more light penetrates into the plant canopy so fungi growth under this condition is reduced (Kanyomeka and Shivute, 2005). Blossom end rot occur due to calcium deficiency (Taylor and Locascio, 2004). Under water deficit stress or high relative humidity limit calcium uptake and transport in plants and causes blossom end rot.…”

Effect of Shoot Pruning and Flower Thinning on Quality and Quantity of Semi-Determinate Tomato (Lycopersicon esculentum Mill.)

There are many constraints of space, light and availability of fruits to harvest in tomatoes greenhouse. Therefore, two experiments were carried out to determine the effect of shoot pruning and flower thinning on quality and quantity of fruits of semi-determinate tomato in a greenhouse of the Faculty of Agriculture and Natural Resources, Persian Gulf University of Bushehr. Experimental design was randomized complete block designs in which the effect of shoot pruning (single branch pruning, double branch pruning, pyramidal pruning and control) or flower thinning (Cluster with 4 and 5 remained flowers and control) were studied separately. Results showed that, leaf area and plants yield were higher in treatments which were pruned than control. Yields from pyramidal pruning and cluster thinning with 5 remaining flowers were significantly higher than other treatments. On the other hand, qualitative study identified that pyramidal pruning increases vitamin C in fruits, but had no significant effect on total soluble solids.

“…In tomatoes, it appears as a water-soaked area at the distal part (style-end) of green fruits aged 12 to 15 day after anthesis. It rapidly develops into black necrotic lesions and can cause severe yield losses (Geraldson, 1955;Spurr, 1959;Taylor and Locascio, 2004). Calcium is widely Locascio, 2004).…”

Differences in Blossom-end Rot Resistance in Tomato Cultivars is Associated with Total Ascorbate rather than Calcium Concentration in the Distal End Part of Fruits <i>per se</i>

Calcium is widely accepted as the main factor responsible for blossom-end rot (BER) appearance in tomato (Solanum lycopersicum L.) fruit. However, reactive oxygen species (ROS), which can damage plant tissues have also been proposed to initiate BER appearance in tomatoes and other fruit-bearing vegetables. Ascorbate, the major antioxidant in tomato fruit, is generally lower during green fruit development, which corresponds to the stage of BER appearance. Accordingly, one hypothesis is that tomato cultivars with a lower susceptibility to BER under salt stress have higher ascorbate contents and thus better control of ROS levels. In this study, to clarify the relationship between BER incidence and oxidative stress, two BER resistant cultivars, 'Managua RZ' and 'House Momotaro' and one BER-susceptible cultivar 'Reiyoh', were cultivated under salinity or standard nutrient solution (control) conditions. Calcium, potassium, magnesium, total hydro-soluble antioxidants, and ascorbate concentrations were measured in the distal pericarp 1 to 2 days prior to symptom appearance and during symptom appearance in healthy and affected fruits. When salt stress was applied, only BER-resistant cultivars showed a significant increase in ascorbate contents prior to BER appearance as compared with their levels under the control condition. In contrast, pre-BER Ca concentrations. A similar tendency was also observed in apple "bitter pit". The ability to increase the fruit antioxidant capacity and maintain mineral balance under salt stress conditions may explain the resistance to BER development in highly resistant cultivars, probably by the avoidance of oxidative-induced cell necrosis and stabilization of the cell membranes, respectively.
