Abstract

The simplest strategy to boost cowpea production is to have an optimum fertilizer level and spacing. The study was performed to assess the effect of variable row spacing and phosphorus (P) levels on the growth and yield of cowpeas. The experiment was carried out using a split-plot design with three planting geometry as the main plot (15 cm × 30 cm, 30 cm × 30 cm, and 45 cm × 30 cm) and three P levels as subplots (20, 40, and 60 kg/ha), each replicated three times. The result demonstrated that P had a significant effect on the number of pods per plant at 100 days after sowing (DAS), pod length at 85 and 100 DAS, and yield of fresh pods. However, P did not significantly impact plant height or number of pods per plant at 70 and 85 DAS. The highest fresh pod yield (1.05 t/ha) and pod length at 85 and 100 DAS (20.33 and 21.16 cm, respectively) were observed at 60 kg/ha P level. Similarly, the highest number of pods per plant at 100 DAS (8.3) was recorded at a P level of 40 kg/ha, which was comparable to that obtained at a P level of 60 kg/ha (8.1). Also, the spacing showed a nonsignificant effect on any of the studied parameters, except for the number of branches per plant at 30 DAS. The 45 cm × 30 cm spacing resulted in the highest number of branches per plant at this stage (2.4).

间距和不同磷水平对尼泊尔当县 Malepatan-1 品种豇豆（Vigna unguiculata (Linn.) Walp.）生长和产量的影响

提高豇豆产量的最简单策略就是采用最佳施肥量和行距。本研究旨在评估不同行距和磷（P）水平对豇豆生长和产量的影响。试验采用分小区设计，以三种种植几何形状（15 厘米×30 厘米、30 厘米×30 厘米和 45 厘米×30 厘米）为主小区，以三种磷水平（20、40 和 60 千克/公顷）为子小区，每个小区重复三次。结果表明，钾对播种后 100 天（DAS）的单株荚数、85 天和 100 天（DAS）的荚长以及鲜荚产量有显著影响。然而，钾对 70 和 85 DAS 时的株高或单株豆荚数没有明显影响。在 60 千克/公顷的钾水平下，85 和 100 DAS 期的鲜荚产量（1.05 吨/公顷）和荚长（分别为 20.33 厘米和 21.16 厘米）最高。同样，在 40 千克/公顷的钾肥水平下，100 DAS 时的单株豆荚数（8.3 个）最高，与 60 千克/公顷的钾肥水平下的单株豆荚数（8.1 个）相当。此外，除了 30 DAS 时的单株分枝数外，株行距对所有研究参数都没有显著影响。45 厘米×30 厘米的株行距在这一阶段的单株分枝数最高（2.4）。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
