Peanut (Arachis hypogaea L.) plays an important role in cropping systems under sandy soils of Vietnam. However, studies on imbalanced fertilizer use on peanut cultivation in sandy soil of Binh Dinh province, Central Vietnam are still limited.
The present study was made to compare two different fertilizer combinations viz., (T1) Control (Farmers’ practice): 24 kg N (urea) + 74 kg P2O5 (Thermophosphate) + 84 kg K2O (KCl) + 100 kg NPK (16 - 16 - 8 - 13S) ha-1 and (T2) 40 kg N (urea) + 90 kg P2O5 (Thermophosphate) + 90 kg K2O (K2SO4) based on 8 tons of cattle manure + 500 kg lime ha-1 on peanut yield, quality and physico-chemical properties of sandy soil in Cat Hanh and Cat Hiep communes, Phu Cat district, Binh Dinh province. All treatments were arranged in a completely randomized block design (RCBD) with 3 replications.
The results showed that the application of fertilizer in combination including potassium and sulfur increased peanut yield (4.35-4.48 tons ha-1), protein content (24.4%), lipid (52.5-52.8%) and improved some soil physico-chemical properties (N (9.09%) and P2O5 (11.04%). Thus, balanced fertilizer application i.e., 8 tons of cattle manure + 40 kg N + 90 kg P2O5 + 90 kg K2O (K2SO4) + 500 kg of lime ha-1 can be recommended for the best peanut production in sandy soil of Central Vietnam.
