Phosphate leachate losses in sandy soil amended with different fertilizers and effects on cowpea yield

Nutrient leaching limits sustainable fertility management of tropical sandy soils. Therefore, phosphate leached from NPK 15:15:15 (NPK), sole compost (SC), phospho-compost (PC), poultry manure (PM), fresh Gliricidia sepium leaves (GL) and integrated (INTG) fertilizers applied at 40 kgP2O5 ha-1 and an unamended soil (AC) in leaching columns containing 2.5 kg soil were studied. Each soil was simulated for leaching at 2,...

Effects of irrigation levels and nitrogen fertilizer rate on grain yield of wheat (Triticum aestivum) at Amibara, Middle Awash, Ethiopia

For three years, the response of wheat grain yield to varying amounts of nitrogen fertilizer and different levels of irrigation was investigated. Three levels of irrigation (100, 75, and 50%ETc) and five nitrogen rates (0, 23, 46, 69, and 92 kg/ha) were used in a split plot design. Irrigation and nitrogen levels both had a considerable impact on wheat grain yield, but there was no interaction between the two. The...

Verification of nutrients standards for diagnosis of Yuhebao lychee (Litchi chinensis Sonn.)

The steady production of Yuhebao lychee (Litchi chinensis Sonn.) is involved in accurate fertilization management. The critical period of nutrient requirement for Yuhebao lychee is during January to June every year in Taiwan because the period is from flowering to fruiting stage. It would serve the references of fertilization if there is an accurate standard for nutrient management of Yuhebao lychee. This study was...
