This paper reviews the results of past research conducted from 1965 to 2000 in two major cassava growing areas, the northeastern and eastern parts of Thailand. This research was carried out by the Field Crops Research Institute, Department of Agriculture (DOA), in collaboration with Kasetsart Uni...

The paper reviews the available data and current activities on agronomic aspects of cassava in Thailand. These activities were carried out by various national research programs in collaboration with CIAT during 1990-1993. The review shows that the inherent fertility of cassava soils has been depl...

Trypsin inhibitor content was determined in the seeds of 21 cowpea (Vigna unguiculata) lines (10 known to be resistant to Callosobruchus maculatus and 11 susceptible) whilst fatty acid composition was determined in 58 lines (11 resistant and 47 susceptible). A wide range in trypsin inhibitor cont...

Long term use of Maresha plow, a conventional plow pulled by oxen, has resulted in the formation of a restrictive layer thereby limiting water movement and aeration as well as root zone penetration in the soil profile. Several studies have shown that improved tillage practices can positively affe...

Whilst irrigation schemes and technologies are extensively promoted in Africa, proper water management guidance for farmers is often lacking. Improper on-farm irrigation management practices lead to poor water distribution, non-uniform crop growth, and disputes in irrigation schemes due to unequa...

Con el fin de medir la validez de la tolerancia a Empoasca kraemeri Ross & Moore en una línea mejorada por resistencia a este insecto, se sembró en tres semestres la línea EMP 414 (tolerante) en comparación con un testigo susceptible, BAT 41. Estos materiales fueron sometidos a diversos regímenes...

El frijol (Phaseolus vulgaris L) es originario de América, reconociéndose dos centros de domesticación: Mesoamérica con cultivares de semilla pequeña y la región andina de América del Sur con cultivares de semilla grande. El frijol se cultiva ampliamente en el mundo en una gran diversidad de zona...
