Low quality of cassava stakes for planting is a major cause that limits cassava growth and productivity. Nutrient contents of the stakes are one possible key factor determining the stake quality. Priming refers to a method to improve the performance of plant propagules, such as seed or cutting, b...
In Cambodia, cassava is mostly grown with little or no fertilizer inputs, but the magnitudes of nutrient balances are not known. This study was conducted to assess nutrient balances for cassava cultivation in Kampong Cham province in Northeast Cambodia. Forty five households in four cassava pr...
This paper examines the potential for phosphorus (P) release from intensively grazed pasture to waterways. In particular it describes the P release processes occurring in riparian buffer strips. Soil samples at three depths (0 2.5, 2.5 7.5, and 7.5 15 cm) were collected from riparian buffer strip...
Phosphorus (P) deficiency is a major constraint for crop production in many parts of the world including Myanmar and field research into management of P fertilizers and P responsiveness of crops on infertile soils has been limited. The purpose of this study is to determine maize yield response to...
The sequential extraction procedure currently used to measure magnesium (Mg) fertilizer dissolution in soils consists of removing dissolved Mg (step 1), and partially dissolved Mg (step 2), followed by an 18?h extraction with 2 M HCl at room temperature to determine undissolved Mg (step 3). This ...
The growth response of Tilapia fish (Oreochromis niloticus) to supplementation with fresh or dried leaves of a sweet variety of cassava was studied in 1 m deep ponds (each 4 m * 2.5 m * 1 m). Rice bran or rice bran mixed with cassava root meal was provided as the energy source (20-24% of feed DM)...
