Influence of Different Seed Rate and Nutrient Media on Growth Attributers of Tray Nursery Rice Seedlings for Machine Transplanting
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 3
Abstract
A experiment was conducted at central farm of Agricultural College and Research Institute, Tamil Nadu Agricultural University, Madurai during the month of October, 2015 to study the effect of seed rate and tray media for production of good quality seedlings for machine transplanting. Treatment comprised in main four level of seed rate viz., 100, 80, 60, and 40 gram tray-1 and nine level of media viz., M1–Native soil, M2 - Native soil + FYM (4:1), M3 - Native soil + VC (4:1), M4 - Native soil + Coir pith (4:1), M5- Native soil + Sand (4:1), M6 - Native soil + FYM + VC (3:1:1), M7 - Native soil + Coir pith + VC (3:1:1), M8- Native soil + FYM + Rice husk (3:1:1), M9- Native soil + FYM+ VC + Rice husk (3:1:0.5:0.5). The maximum seedlings growth attributes viz., seedling height, root length, dry matter product (DMP) and SPAD values were noticed under combination of 40 g seed rate tray-1 with Native soil + Coir pith + VC than that of other treatment combinations. Hence, moderate seed rate of 80 g tray-1 sowing in the media contain native soil + Coir pith + VC at 3:1:1 ratio can be recommend in production of sturdy rice seedling for machine transplanting.
