Abstract

Excessive leaf production in winged bean may delay the flowering time and reduces the yield, therefore, shoot pruning and additional fertilizer were applied in order to improve yield. The research was carried out at Leuwikopo Experimental Station, IPB University, Bogor from January to July 2022. The study used a randomized complete block design with 2 factors and three replications. The first factor was three types of shoot pruning, namely without shoot pruning, shoot pruning at 15, and 30 cm height. Pruning was conducted at 7 weeks after transplanting (WAT). The second factor was four doses of fertilizers (0, 6.25, 12.5, and 18.75 g of NPK (16-16-16) per plant). The additional fertilizer was given every two weeks from 7 until 15 WAT. The variables observed were the morphophysiological characters, shoot auxin levels, plant nutrient levels, pod yield, pod number, and pod flavonoid content. The results showed that plant’s biomass increased with additional fertilizer, lower relative growth rate and higher auxin content was from 15 cm pruning. The interaction of two factors affected flowering time and flavonoid content. Shoot pruning and 6.25 g NPK delayed flowering by 0.7-1 day. The highest flavonoid content was found in the plant without pruning and additional fertilizer. Plant yields were not significantly affected by treatments. Keywords: auxin; flavonoid content; flowering time; leaf nutrient; young pods

Abstract

Bitter melon (Momordica charantia L.) is valued for its anti-diabetic properties due to terpenoid compounds like charantin, but production struggles to meet market demands. This study aimed to analyze the response of plant growth characteristics, fruit production, and terpenoid compound production in bitter melon fruit by improving phosphorus availability through guano fertilizer application as additional organic fertilizer in organic cultivation. The experiment was conducted from May to September 2024 at the IPB experimental station in Cikarawang, Bogor, Indonesia. The experiment used a randomized complete block design with varying guano fertilizer doses (0, 152, 304, and 456 g per plant). Observations were conducted on 10 sample plants per experimental unit. The observed characteristics included vegetative and reproductive growth, fruit production, and total terpenoid production. Terpenoid analysis was performed using a colorimetric method with an ELISA reader. The results showed that guano fertilizer significantly affected several plant growth and production variables. Higher doses increased several values of vegetative growth parameters, flower numbers, and fruit production. The 304 g guano per plant yielded the highest concentration and production of terpenoids. This study demonstrates the potential of guano fertilizer to enhance bitter melon growth, yield, and terpenoid content, contributing to improved production to meet market demands. Keywords: net assimilation rate; organic; phosphorus; relative growth rate
