Botanical composition chemical analysis and cellulase solubility of rice straw from different varieties

Abstract

Investigations carried out by the Tropical Development and Research Institute (TDRI) in association with the International Centre for Agricultural Research in Dry Areas (ICARDA), Syria, have shown relationships between the physical characteristics of barley and the nutritive value of its straw. The objectives of the work reported here were to examine rice straw and study the relationships between morphological characteristics (height, harvest index, days to maturity), the proportions of botanical components, chemical constituents and nutritive value of the straw as measured by in vitro cellulase solubility. In addition, environmental effects on some of these characteristics were studied by examining inter-plant variations.
