Abstract

The impact of nitrogen (N) and boron (B) foliar applications on Solanum melongena growth, yield, and phytochemicals was studied. The impact of foliar applications using N levels (0, 0.25%, 0.5%, and 1%) and B levels (0, 0.1%, 0.25%, and 0.5%) following a randomized block design with three replications was studied. With the increase in N level, the yield characters increased. Foliar application of N shows the maximum height of plant (112.5 cm), number of leaves (186.0), leaf area (46.20), number of branches (7.67), number of blossom flowers/plant (21.25), number of fruits/plant (11.42), fruit length (10.97 cm), fruit width (7.39 cm), fruit volume (305.7), fruit weight (12.67 g), fruit yield (12.78), protein (10.9%), total carbohydrates (27.5%), and crude fiber (7.21%) while decreasing minimum days at 50% appearance of flowers (48.0). In the case of B application, the maximum height of the plant (112.0 cm), number of leaves (187.6), leaf area (47.82), number of branches (7.67), number of blossom flowers/plant (22.08), number of fruits/plant (11.33), fruit length (10.95 cm), fruit width (7.35 cm), fruit volume (298.0), fruit weight (206.1 g), fruit yield (12.13), protein (9.31%), carbohydrates (30.2%), TSS (4.20), crude fiber (7.34%), DPPH (4.68 mg/mL), Chl a (1.39), Chl b (0.53), TPC (60.78), DAO activity (81.43), and PAO activity (39.10) were observed, while decreasing minimum days at 50% appearance of flowers (48.33). Application of N at 0.5% and B at 0.25% increased the growth, yield parameters, and phytochemical contents of S. melongena. The impact of different nitrogen and boron foliar applications on eggplant growth, phytochemicals, and quality attributes is significantly improved.

叶面施肥氮和硼对茄子（Solanum melongena）生长、植物化学物质和质量属性的影响

摘要研究了叶面施肥氮（N）和硼（B）对瓜茄（Solanum melongena）生长、产量和植物化学物质的影响。采用三次重复的随机区组设计，研究了叶面施肥对氮含量（0、0.25%、0.5% 和 1%）和硼含量（0、0.1%、0.25% 和 0.5%）的影响。随着氮含量的增加，产量特征也随之增加。叶面施肥的结果表明，硼肥施用量最大时，株高（112.5 厘米）、叶片数（186.0）、叶面积（46.20）、分枝数（7.67）、开花数/株（21.25）、果实数/株（11.42）、果实长度（10.97 厘米）、果实宽度（7.39 厘米）、果实体积（305.7）、果实重量（12.67 克）、果实产量（12.78）、蛋白质（10.9%）、总碳水化合物（27.5%）和粗纤维（7.21%）。在施用 B 的情况下，最大株高（112.0 厘米）、叶片数（187.6）、叶面积（47.82）、分枝数（7.67）、开花数/株（22.08）、果实数/株（11.33）、果实长（10.95 厘米）、果实宽（7.35 厘米）、果实体积（298.0）、果实重（206.观察到的结果包括：果实长度（10.95 厘米）、果实宽度（7.35 厘米）、果实体积（298.0 克）、果实重量（206.1 克）、果实产量（12.13）、蛋白质（9.31%）、碳水化合物（30.2%）、总悬浮固体含量（4.20）、粗纤维（7.34%）、DPPH（4.68 毫克/毫升）、Chl a（1.39）、Chl b（0.53）、TPC（60.78）、DAO 活性（81.43）和 PAO 活性（39.10），同时花出现率达到 50%的最短天数（48.33）有所减少。施氮量为 0.5%、施硼量为 0.25%可提高西红花的生长、产量参数和植物化学物质含量。不同氮和硼的叶面施肥对茄子生长、植物化学物质和质量属性的影响显著提高。
