Studies on sustainable tomato seedling production in plug tray using organic amendments under protected sturucture

Now a day, plug tray technology is commonly adopted by nurserymen for raising of tomato seedling. After germination of seed, hapless supplementation of inorganic fertilizers, PGR, and plant protection measures affects nursery as well as post-transplant stages of seedlings. So, to protect the environment from chemicals and hazardous polluting products, and maintain the ecological balance, sustainability, and recycling of natural resources for future generations, the present investigation was carried out with different organic amendments viz. Control (T0), Bijamrut + Trichoderma harzianum + Beauveria bassiana (T1), Bijamrut + Trichoderma harzianum + Beauveria bassiana + NPK consortia (T2), Bijamrut + Jivamrut (T3) and Bijamrut + Waste decomposer (T4). The results of the study revealed that, the significantly earliest days to germination (4.07), maximum germination per cent (90.69), the height of seedling at 20 days after sowing (8.00 cm) and at transplanting stage (20.56 cm), minimum days to transplant (28.93) and maximum survival per cent (88.36) of the seedling at transplanting was observed in the application of Bijamrut (200 ml/kg) through seed treatment and media enrichment with Trichoderma harzianum (50 g) and NPK consortia (50 ml) per 10 kg media and foliar spray of Beauveria bassiana (0.6%) at 10 and 20 days after sowing under 50 per cent green shade net.
