Effect of Plant Spacing on Yield and Quality of \u3cem\u3eLeucaena leucocephala\u3c/em\u3e subsp.

Leucaena leucocephala (Lam.) de Wit commonly known as leucaena, is one of the most productive tree legumes available to tropical agriculture. Leucaena leucocephala subsp. glabrata 34/92 was introduced to Thailand from Oxford Forestry Institute in the year 1996 with another 16 lines and evaluated in Thailand. It was chosen as a potential psyllid resistance and high forage edible yield (Phaikaew et al., 2005). Seed lot 34/92 is derived from K636 through selfing (Hughes, 1993). This report is a part of ‘research and development of Leucaena leucocephala subsp. glabrata production as protein source in commercial feed project’ which contain a set of experiment on management of Leucaena for forage production, seed production and pilot project on produce leaf meal and Leucaena seed by small holder farmers aim to commercialize leucaena leaf meal by smallholder farmers
