NOVELTY - Method for planting tomato plants in matrix, involves (a) selecting tomato seedlings for collecting matured tomato seeds, (b) immersing the tomato seeds in hot water, (c) immersing the tomato seeds in medicinal solution for 7-8 hours, (d) placing immersed seeds in wet towel, and maintaining temperature at 25-30 degrees C for 20-24 hours for accelerating germination of seeds, (e) sterilizing germinated tomato seeds, and (f) sowing sterilized germinated seeds on matrix, and growing tomato seedlings.    USE - The method is useful for planting tomato plants in matrix (claimed).    ADVANTAGE - The method is performed in a cost-effectively and environmentally-friendly manner, prepares highly nutritious matrix, improves seed germination rate by more than 90%, and emergence rate of tomato seedlings by 80-85%, produces healthy and strong seedlings, and promotes growth of the seedlings, and survival rate of the tomato seedlings by greater than or equal to 95%.    DETAILED DESCRIPTION - Method for planting tomato plants in matrix, involves (a) selecting tomato seedlings for collecting matured tomato seeds, (b) immersing the tomato seeds in hot water at 80-90 degrees C for 0.6 hours, again immersing the tomato seeds in water at 60-70 degrees C for 2.5 hours, again immersing the tomato seeds in water at 40-50 degrees C for 9 hours, and again immersing the tomato seeds in water at 20-30 degrees C for 18 hours, (c) immersing the tomato seeds in medicinal solution for 7-8 hours, (d) placing immersed seeds in wet towel, and maintaining temperature at 25-30 degrees C for 20-24 hours for accelerating germination of seeds, (e) sterilizing germinated tomato seeds, and (f) sowing sterilized germinated seeds on matrix, and growing tomato seedlings. The matrix comprises 60 pts. wt. pine sawdust, 30 pts. wt. cottonseed shell, 10 pts. wt. kaolin, 15 pts. wt. field soil, 4 pts. wt. inorganic fertilizer and 4 pts. wt. Chinese herbal medicine. The medicinal solution comprises 20% rice vinegar, 2% edible salt, 8% vitamin B12 and 70% purified water. The inorganic fertilizer comprises urea, calcium superphosphate and potassium chloride in a weight ratio of 4:2:1. The Chinese herbal medicine comprises cassia twig, Chrysanthemum, Fagopyrum dibotrys rhizome and dried orange peel in a weight ratio of 3:2:1:2. An INDEPENDENT CLAIM is included for method for preparing the matrix, which involves (i) mixing the pine sawdust, cottonseed shell, kaolin, field soil and inorganic fertilizer, spraying 5 pts. wt. water on mixture, sealing the mixture for 15-20 days, and turning mixture for 2 times for every 5-8 days, (ii) crushing and mixing the cassia twig, Chrysanthemum, F.dibotrys rhizome and dried orange peel, and sealing and fermenting obtained mixture for 10-15 days using effective microbial (EM) composition, and (iii) uniformly mixing fermented product with product obtained in step (a). The EM composition is prepared by mixing Lactobacillus and yeast.
