Abstract

Thailand is a tropical monsoon country in South East Asia. About 39 and 29.5% of the total land area (51.3 million ha) are farm holding land and forest land; and 64% of the surpassing 52 millions population is agriculture population. Per capita income of the agriculture population is c. 1:8.5 of the non-agriculture population. The major cultivated crops are paddy, field crops, fruit trees, tree crops and vegetables, etc. Land productivity is low and population growth is high which make a considerable pressure on the available cultivated land. As a result, forest land was markedly encroached for expansion of cultivated land, which caused a severely damage to the ecology and natural resources. At present, Thailand’s soil is subjected to degradation and erosion. Reforestation and agroforestry have been operated to sustain the rate of deforestation, but still lags behind. Four main types of agroforestry are practiced throughout Thailand. Agrisilvicultural system, Silvopastoral system, Apisilvicultural system and Pisci-silvicultural system. For Southern Thailand, horticulture crop likes fruit trees and rubber are integrated in the system instead of field crops. Up-to-date, Apisilvicultural system seems to be the most productive system for this region, whilst Pisci-silviculture received less attention.

Abstract

An experiment of 5 pasture legume species :- C. pubescens, Centrosema sp.n. CIAT5112, C.agostini 675, C.brasilianum CPI 40062 and L.purpureus cv. Highworth was arranged in a CRD in Bangkok with 8 replicates (pot) and one plant per pot. This experiment was designed to study growth, dry matter yield and crude protein content in leaf and stem fractions. Leaf dry matter expressed as percentage of total top dry matter production at 105 days ranged from 56.8-42.8% for the 4 vegetative species and was only 25.9% for C.agostini which flowered at 58 days from sowing. All species had higher crude protein content in leaves than in stems and varied greatly among species. The greatest value recorded in leaves was 25.2% for L.purpureus and the lowest 11.75% for C.pubescens, while the values for stems were less variable.
