Abstract

The purpose of this study was to evaluate how the development and yield of the cucumber plant of the Roberto variety (Cucumis sativus L.) were influenced by the lateral branch pruning method and the application rate of NPK fertilizer. The doses of NPK fertilizer, particularly without fertilizer (D0), 10 g/plant (D1), 20 g/plant (D2), and 30 g/plant (D3), as well as lateral branch pruning methods, i.e., without pruning (P0), pruning at the first to fifth nodes (P1), and pruning at the sixth to tenth nodes (P2), were the treatments evaluated. Factorial design in random block design (RBD) with three replicates was used to conduct the study. The number of plants, height, leaves, male and female flowers, diameter and length of fruits, and weight were among the observation criteria. The number of leaves, the number of male and female flowers, and the diameter of the fruit were all significantly affected by lateral branch pruning, according to the data. In addition, the NPK fertilizer dosage significantly affected the yield and growth of cucumbers on most of the characteristics measured. Yields increase synergistically when pruning and NPK fertilizer dosage are combined. In conclusion, the Roberto cucumber variety can maximize growth and yield by combining lateral branch pruning with the right dosage of NPK fertilizer. Cucumber cultivation techniques can be based on the findings of this study to increase productivity.

Abstract

This research was conducted on Nusalaut Island, Central Maluku Regency, aiming to determine the land suitability class of several food crop commodities. Data collection and analysis methods include: (1) analysis of thematic maps, (2) preparation of Land Unit Maps (PSL), (3) field checking using the field survey method, which uses independent survey techniques; (4) observation of land characteristics and quality in each land unit, and (5) analysis of land characteristics and quality in each land unit. The follow-up analysis is in the form of: (1) determining the level of land suitability and (2) producing a map of land suitability classes for food crop commodities on the island of Nusalaut. The results of the assessment of land suitability class on food crops cassava, sweet potato, and corn included in the category of marginally suitable class (S3) with limiting factors of water availability (wa), rooting media (rc), slope (eh) and unsuitable class (N). Cassava plantations had a marginally suitable class (S3) with a limiting factor (wa, rc) of 1452.4 ha or 66.51% and for an unsuitable class (N) of 731.52 ha or 33.50%. Sweet potato plants have a marginally suitable class (S3) with a limiting factor (wa, rc, eh) covering an area of ​​1452.38 ha or 66.5% and for an unsuitable class (N) an area of ​​731.52 ha or 33.50%. Corn plants have a marginal suitable class (S3) with a limiting factor (wa, rc) covering an area of ​​1452.38 ha or 66.5% and for an unsuitable class (N) an area of ​​731.52 ha or 33.50%.
