| Summary: | ABSTRACT
The effect of four kinds of calcium fertilizer CaO, CaCO3, CaSO4 and Ca(NO3)2 and 4 levels of calcium 0, 10, 20 and 40 kg Ca/ha on grain yield of grounnut (Arachis hypogaea L.) ? the local variety ?dau Vo or dau Tau? ? was evaluated in Long Son village, Cau Ngang district, Tra Vinh province in the seasons of Winter-Spring (2002). The objectives of the experiment were finding the appropriate kind and level of calcium to effect the grain yield on the sandy soils.
The result shows that grain yield increases significantly when calcium was applied. To compare with control treatment (without Ca application) amount range of calcium fertilizer from 20 to 40 kg Ca/ha gave the best result. Among four kinds of calcium fertilizer, CaSO4 showed much better than CaO, CaCO3 and Ca(NO3)2. Ca(NO3)2 was good when applied 10 kg calcium/ha, if increasing calcium rate higher than 40 kg/ha the grain yield will decrease.
