Abstract

Cucumber is a popular vegetable that can be consumed fresh or processed into pickles, preserves, and other products. Efforts to enhance cucumber yield have been made through the application of Azolla compost and inorganic nitrogen (N) fertilizer. This study aimed to evaluate the interaction between different doses of Azolla compost and inorganic N fertilizer on cucumber growth and yield, as well as to determine the optimal doses of both fertilizers. The experiment was conducted from December 2021 to February 2022 in Medan Baru, Muara Bangkahulu District, Bengkulu City. A factorial randomized complete block design was employed with two factors: (1) Azolla compost doses (0 g plant-1, 90 g plant-1, 180 g plant-1, and 270 g plant-1) and (2) inorganic N fertilizer doses (0 g plant-1, 0.9 g plant-1, 1.7 g plant-1, and 2.5 g plant-1), resulting in 16 treatment combinations, each replicated three times. Data were analyzed using ANOVA at a 5% significance level, followed by Duncan’s Multiple Range Test for significant variables. Results indicated that there were no significant interaction effects between Azolla compost and inorganic N fertilizer on cucumber growth and yield. The 180 g plant-1 dose of Azolla compost produced the best results in terms of vine length, leaf number, fruit weight per plant, and plant dry weight. However, inorganic N fertilizer had no significant effect on cucumber growth and yield. Further research is needed to explore the effects of inorganic N fertilizer and the potential of Azolla as an environmentally friendly organic fertilizer in sustainable agricultural systems.

Abstract

Cayenne pepper is a horticultural crop with high economic value, and its productivity can be improved through plant breeding programs. Genotypic and phenotypic variability, and heritability are important parameters for such programs. This study aimed of obtaining information on genotypic and phenotypic variability as well as heritability of generative traits, yield components, and the yield in 39 cayenne pepper genotypes. The research was conducted from May to October 2024 at the Experimental Farm, the University of Bengkulu. A Randomized Complete Block Design (RCBD) was used, involving 39 genotypes planted in three replications, with 20 plants per replication. The results showed broad genotypic variability was found in days to anthesis, days to first harvest, number of fruits per plant, fruit diameter, fruit length, pedicel length, and average fruit weight. Broad phenotypic variability was observed in all traits. High heritability was found in days to anthesis, fruit diameter, fruit length, and average fruit weight. These findings are highly valuable for determining effective selection strategies in plant breeding and the development of superior cultivars. Keywords: breeding, chili pepper, diversity, genotypic variance, phenotypic variance.
