Residual Effect of Integrated Nutrient Management on Seed Quality Attributes at Different Fruit Pickings of Tomato (Lycopersicon esculentum Mill.)

Residual effect of nutritional treatments, consisting of various organic sources viz., FYM, poultry manure, neem cake, azotobacter, VAM, PSB, and pea crop residue, along with the inorganic fertilizers, was tested on seed quality attributes of tomato at different fruit pickings. The treatments were actually administered in the first crop in the okra- pea–tomato cropping system. The fruits harvested in the first picking resulted in greatest 1000 seed weight, germination percentage, seedling length and seedling vigour index having considerable differences over the late pickings. Among different treatments, the application of VAM +50% P and full dose N and K through fertilizers, proved best almost in all the fruit picking with respect to all the above seed quality attributes, closely followed by the application of PSB +75% P and full dose of N and K through fertilizers
