2. Fruit cracking:
Fruit cracking: occurs for middle of the May. Reduced transpiration has increased cell turgidity and contributed to tomato fruit cracking. Reduced transpiration occurs even in summer when fruit are grown in green house. Cracking also occurs in rainy season when rains fall in long dry spell. Presence of water on the surface of fruit is more conducive in cracking than high soil moisture. Boron deficiency in the soil also causes fruit cracking. They are two types of cracking. i. radial cracking: occurs mostly at ripe stage. ii. Concentric cracking: it is common in mature green stage. Remedies: use of resistant cultivars like Sioux, Punjab chuhara. Picking of the fruit before the full ripe stage. Soil application of Borax @ 10 – 15 kg per ha. Regulation of soil moisture. Misting (spray of cool water).
