Abstract

An experiment was conducted to evaluate the effects of peat moss, adhesives, and various phosphorus materials as coating materials on the germination and early growth of tall fescue (Festuca arundinacea Schr.), orchardgrass (Dactylis glomerata L.), alfalfa (Medicago saliva L.), and birdsfoot trefoil (Lotus corniculatus L.) at the Experimental Livestock Farm, Yonam College of Agriculture in 1997. Germinating energy of tall fescue seed coated with 10% peat moss was the highest, but germination was improved when peat moss was below 20%. Establishment and early growth of tall fescue seed coated were improved as the level of peat moss increased (not significant at p $lt; 0.05). Among different adhesives, germination of tall fescue seed coated with 3% cetyl-methyl cellulose was significantly higher than other adhesives, but no significant difference was observed in tall fescue with the percentage of coating materials. Germinating energy and germination of orchardgrass seed coated with tri-calcium phosphate (TCP) and mono-calcium phosphate (MCP) were higher than other phosphates (p $lt; 0.05). Germinating energy of tall fescue seed coated with TCP was the highest, but germination was improved when seed was coated with MCP. Germinating energy and germination of alfalfa seed coated with TCP were the highest among all treatments. Germinating energy of birdsfoot trefoil seed coated with MCP was higher compared with other phosphates (p $lt; 0.05). However, germination of birdsfoot trefoil seed was not influenced by coating. Tall fescue seed coated with below 20% peat moss gave greater improvement in germinating energy and germination. TCP shown a positive effect on germination. Therefore, methyl cellulose could be recommended as the best adhesives and TCP may be recommendable as a phosphorus source for seed coating.
