| Summary: | This study aimed to determine the effect of different fertilizer materials, namely NPK-based nanofertilizers, conventional chemical fertilizers, and organic fertilizers, as well as planting methods on the productivity and quality of melons cultivated under greenhouse conditions. A randomized complete block design was used involving five treatments: control (no fertilizer added), NPK fertilizer (20:20:20) at 300kg ha-1, nano fertilizer (10:12:12) at 150ml in 200 L ha-1, NPK foliar fertilizer (20:20:20) 20 g L-1, and organic fertilizer at 20 L in 300 L ha-1 through fertigation, as well as two planting methods (transplanting and direct seeding). These treatments and the control were replicated 4 times, and after the crops were established various growth and yield parameters were measured, such as plant height, leaf chlorophyll content, fruit weight, fruit diameter, and sugar content. The data was analyzed using analysis of variance (ANOVA) and SPSS version 26 at the 5% significance level was used. The results indicated that overall fertilizers application and planting methods significantly (p < 0.05) increased the studied parameters. The tallest plants (172.6 cm) were from plots planted by direct seeding and the application of NPK (20:20:20) fertilizer. Similarly, plants with direct seeding treated with either NPK fertilizer (20:20:20) or nano-fertilizer (10:12:12) recorded higher fruit weights (35.6 kg plot-1), larger fruit diameters (44.5 cm), and fruit sugar content (8.8%), compared to the control which registered the lowest values at 6.7 kg plot-1, 42.2 cm, and 7.2%, respectively. The results suggest that direct seeding together with balanced NPK fertilizer (20:20:20) and nano-fertilizer applications can be recommended for growing melons in the greenhouse |
