Abstract

This research determines the response of purple eggplant (Solanum melongena L.) to the application of triple superphosphate (TSP) and Azolla Liquid Organic Fertilizer (POC). The study was carried out at the Experimental farm of the Faculty of Agriculture at Riau Islamic University, Pekanbaru. The experimental design was a factorial randomized arrangement featuring two main components: Azolla POC applied in four volumes (0, 200, 400, dan 600 ml per polybag)) and TSP fertilizer administered in four quantities (0, 2,5, 5, dan 7,5 g per tanaman). This design resulted in 16 treatment combinations, each replicated three times, totaling 48 experimental units. The study included 192 polybag plants, with four plants assigned to each unit and two of those sampled for analysis. The parameters measured included plant height, age at flowering, age at harvest, number of fruits per plant, weight of individual fruits, total fruit weight per plant, and number of remaining fruits on each plant. After conducting statistical analyses, the data were evaluated using the BNJ test at a 5% significance level. The results of the research on the combination of Azolla POC and TSP were significant on the observed parameters. Specifically, plant height, age at flowering, age at harvest, number of fruits per plant, weight of individual fruits, total fruit weight per plant, and number of remaining fruits on each plant; the best treatment was a combination of Azolla POC 600 ml polybag and TSP 7.5 g/plant. The main effect of Azolla POC was significant on all parameters; the best treatment was Azolla POC 600 ml polybag. The main impact of TSP was substantial on all observed parameters; the best treatment was a TSP application of 7.5 g per plant

Abstract

Riau is home to a wealth of genetic resources distributed across various regions, including local banana varieties found in Indragiri Hulu. A study titled "Morphological Characteristics of Four Types of Bananas (Mussa spp)" was conducted from September to November 2023 to explore the morphological traits and shelf life of these local bananas. The study involved designing research parameters, collecting data through field identifications and observations, and analyzing the data using the STAR and DMRT applications at a 5% significance level. Kinship relationships were assessed using the MVSP 32 application with the UPGMA method, analyzed through NTSys-pc 2.1 software, with results presented in a dendrogram format. The study observed nine qualitative and eight quantitative morphological characteristics. The dendrogram revealed that the four local banana varieties from Indragiri Hulu could be grouped into two main clusters. The first group includes Banten, Kepok, and Lilin bananas, displaying a 50% similarity based on traits such as fruit shape, cross-section, and skin color before and after ripening. The second group consists of a single variety: Kepok bananas. Notably, Kepok and Banten bananas exhibited closer similarities based on characteristics such as fruit weight per fruit, the number of fruits per bunch, and fruit length. Overall, these four banana types exhibit diversity in traits related to the number of fruits per bunch and the thickness of the fruit skin.

Abstract

Green chili (Capsicum annuum L.) is a high-value horticultural crop whose vegetative growth is strongly influenced by nutrient availability, particularly nitrogen. Liquid organic fertilizer (LOF) derived from lamtoro leaves has potential as an environmentally friendly alternative fertilizer. This study aimed to evaluate the effects of dosage and application timing of lamtoro leaf liquid organic fertilizer on the vegetative growth of green chili. The research was conducted from May to August 2024 in Padang Lawas Utara, North Sumatra, using a factorial randomized block design with two factors. The first factor was LOF dosage, consisting of four levels: no LOF (D0), 100 ml/polybag (D1), 150 ml/polybag (D2), and 200 ml/polybag (D3). The second factor was application timing, namely 7 days after planting (DAP) (W1), 14 DAP (W2), and 21 DAP (W3), with three replications. Observed parameters included plant height, number of leaves, and stem diameter. Data were analyzed using ANOVA followed by the Least Significant Difference (LSD) test at the 5% level. The results showed that LOF dosage significantly affected all vegetative growth parameters of green chili. The highest plant height, number of leaves, and stem diameter were obtained at the dosage of 200 ml/polybag. Application timing at 14 and 21 DAP resulted in better vegetative growth than at 7 DAP. The combination of 200 ml/polybag LOF dosage with application timing at 14 and 21 DAP was the most effective treatment for improving vegetative growth of green chili.
