Abstract
The phosporus (P) and potassium (K) fertilization can maximize the profitability of peanut cultivation. Thus, the aim of this study was to evaluate the basic fertilization with P and K on the grain yield and production components of creeping peanut. The experiment was performed in a randomized blocks design, in a 2 x 3 + 1 factorial scheme, with two doses of K (30 and 60 kg ha -1 of K 2 O) and three levels of P (60, 90 and 120 kg ha - 1 of P 2 O 5 ) at sowing, and an additional treatment without the basic fertilization, with four replications. The cultivar Runner IAC 886 was used. Pod yield, grain yield, number of pods per plant, number of pods with grains per plant, the percentage of pods without grains, 100 grains weight and number of seeds per pod, were evaluated. The P and K fertilization at sowing promotes increase of about 38 and 49% in pod yield and grain yield, respectively, in creeping peanut. The highest values of pods with grains are observed with the application of 120 kg ha -1 of P.
施磷钾肥可使花生种植效益最大化。因此，本研究的目的是评价磷钾基本施肥对匍匐花生籽粒产量和生产成分的影响。试验采用随机区组设计，采用2 × 3 + 1因子设计，播种时施2剂钾肥(钾肥30和60 kg ha -1)和3剂磷肥(钾肥60、90和120 kg ha -1)，外加1个不施肥处理，共4个重复。选用品种“跑者”IAC 886。对单株荚果产量、籽粒产量、单株荚果数、单株有粒荚果数、无粒荚果百分率、百粒重和每荚种子数进行了评价。播期施磷、施钾可使匍匐花生的荚果产量和籽粒产量分别提高约38%和49%。施磷肥120 kg ha -1时，荚果带粒值最高。
