The experimental design used was factorial 4 x 4 in Completely Randomized Design (CRD). The first factor was the administration of NPK Mutiara fertilizer consisting of 4 levels, namely: 0, 5, 10, and 15 grams/plant, and the second factor Nasa liquid organic fertilizer consisted of 4 levels, namely: 0, 3, 6, and 9 cc/plant. so that 16 combinations of treatments were obtained. Each combination of treatments consisted of 3 replications so that 48 units of the plot were obtained. Data from the observations were analyzed statistically (variance analysis) and BNJ advanced tests at the level of 5%. The parameters observed were flowering age, harvest age, stem diameter, fruit weight per fruit, the thickness of fruit flesh, and taste test. Research shows that the interaction of NPK Mutiara fertilizer and Nasa liquid organic fertilizer does not significantly affect all parameters, but singly NPK Mutiara fertilizer and liquid Nasa organic fertilizer give an influence on the parameters of observation. The main influence of NPK Mutiara fertilizer influences all observation parameters, namely flowering age, harvest age, stem diameter, widest leaf area, fruit circumference, fruit weight per fruit, production per plot, and thickness of fruit flesh. The best treatment is the administration of Pearl 5K NPK/plant (K1). While the main factors for the provision of liquid organic fertilizer Nasa affect the parameters of flowering age, harvest age, and widest leaf area. The best treatment is the administration of 6 ml/l water (N2) liquid organic fertilizer.

Melon (Cucumis melo L.) contains various important vitamins and minerals, while melon consumption in Indonesia is still far below the standard. The increase in melon production every year has not met the needs of melons. Intensification of acid dry land is one of the efforts to increase melon production, because of the vast potential of the land, but it is necessary to improve the soil properties. The purpose of this study was to test the formulations on the growth and yield of melon plants on acid dry land. The study was conducted in a greenhouse using a non-factorial Randomized Block Design (RBD), with 8 treatments, namely: (A) without Lime + Phonska NPK Fertilizer (100%); (B) without Lime + Phonska NPK Fertilizer + Cow Manure (50%:100%); (C) without Lime + Phonska Npk Fertilizer + Petrobio Fertilizer (50%:100%); (D) without Lime + Phonska NPK Fertilizer + Cattle Fertilizer + Petrobio Fertilizer (50%:50%:50%); (E) with Lime + Phonska NPK Fertilizer (100%); (F) with Lime + Phonska Npk Fertilizer + Cow Manure (50%:100%); (G) with Lime + Phonska Npk Fertilizer + Petrobio Fertilizer (50%:100%); (H) with Lime + Phonska Npk Fertilizer + Cow Manure + Petrobio Fertilizer (50%:50%:50%) with 4 replications. Data analysis used Duncan's Multiple Range Test. The results showed that the fertilizer formulation with additional lime had a significant effect on fruit weight, fruit diameter, and fruit harvest age.

In different crop plants, combining ability and heterosis are used as important diagnostic tools for assessing the performance of parental genotypes and their hybrids. This research aimed to evaluate heterotic and combining ability effects in the diallel crosses of melon (Cucumis melo L.) for yield- and quality-related traits. Seven melon (C. melo L.) genotypes were grown and crossed in a complete diallel fashion to produce F1 hybrids. During the 2019 crop season, 49 melon genotypes (7 parents + 42 F1 hybrids) were grown in a randomized complete block design with three replications. Observations were made for seven characters. Analysis of variance revealed significant (P ≤ 0.01) differences among the melon genotypes for harvest age, fruit flesh thickness, fruit total soluble solids, fruit length, and fruit diameter and merely significant differences (P ≤ 0.05) for fruit weight. Combining ability analysis revealed that mean squares due to general combining ability (GCA) were significant for fruit diameter but were nonsignificant for all other traits. However, mean squares due to specific combining ability (SCA) were significant for all traits. The parental genotypes PK-165, PK-464, and PK-669 exhibited the highest and desirable GCA effects for yield and quality traits. Hence, these genotypes could be used to generate high-yielding hybrid/open-pollinated cultivars. GCA:SCA ratios further revealed that the traits of harvest age, fruit flesh thickness, fruit total soluble solids, fruit length, and fruit weight were controlled by dominant gene action, whereas fruit diameter was managed by additive and dominant genes. The majority of the traits were controlled by nonadditive gene action, verifying that the said breeding material could be efficiently used for the production of hybrid cultivars on the basis of heterotic effects.
