Abstract

Porang (Amorphophallus onchophyllus) has many benefits for industry and health, because of the high content of glucomannan in its tubers. Porang needs to be developed, but the problem is getting a uniform source of tuber seeds. To get the uniform tuber seeds by dividing them. This study aims to get a uniform source of tuber seeds. This study was conducted in the field and laboratory. The experiment was arranged in a CRD. There are two factors, in seed tuber division: U1= Intact tuber, U2=Tuber cut in 2, U3=Tuber cut in 3 parts, and U4=Tubers cut into 4 parts. The second factor is fertilizer consisting of Urea, Za, and Phonska. The results of the combined treatment between tuber division and fertilizer treatment showed no significant interaction in all observed parameters. The seed tuber division treatment affects the bud break time, plant height, stem diameter, and canopy width, only at the beginning of growth. U1 gives the highest growth. The various fertilizer treatments only had a significant effect on plant height and stem diameter at 7 and 8 WAP. The treatment of splitting tuber seeds can replace intact tubers to be used as Porang tuber seeds

Abstract

Long bean (Vigna sinensis L.) is a valuable vegetable commodity recognized for its high nutritional value; however, its production in Indonesia has declined. This decrease can be attributed to improper cultivation techniques. To enhance production, strategies such as NPK fertilization and the application of growth regulators, specifically gibberellic acid (GA3), can be employed to improve yields. The combination of these two methods has the potential to improve both the growth and yield of long beans. This study employed a randomized complete block design (RCBD) with two factors, where each treatment combination was replicated three times. Data analysis was conducted using analysis of variance (ANOVA). This research aims to provide insights and recommendations regarding the most effective doses of NPK fertilizer and GA3 concentrations to enhance growth and yield. Specifically, it seeks to determine the optimal concentration of GA3 that promotes the growth and yield of long bean plants. The combination of NPK fertilizer and GA3 had a significant influence on the growth and yield of long bean plants. The treatment of NPK at 15 g/plant combined with GA3 at 100 ppm resulted in increased plant height, while NPK at 5 g/plant combined with GA3 at 100 ppm led to a higher number of fruits. Additionally, the combination of NPK at 15 g/plant and GA3 at 150 ppm significantly increased pod weight. Furthermore, the individual treatments of NPK at 15 g/plant and GA3 at concentrations ranging from 100 to 150 ppm also positively affected the growth and yield of long bean plants.

Abstract

Hydroponics serves as an alternative to conventional land-based agriculture. This technique enables the cultivation of vegetables in regions with poor fertility or limited space and high population density. The hydroponic planting system's advantage is based on its ability to precisely regulate nutrients. Ensuring adequate nutrition will yield optimal outcomes and be economically efficient. A hydroponic system has long been used to grow pakchoy and samhong plants. The purpose of this study is to ascertain how best to utilize AB-Mix nutrition to achieve the best growth possible for both varieties of mustard. The experiment uses a Completely Randomized Design (CRD) factorial. The first factor are concentrations of AB-mix, 1000 ppm, 1200 ppm, and 1400 ppm. The second factor is Brassica spesies are samhong and pakcoy. There are six treatment combinations, and they were repeated five times. Observations on plant height and leaf number are carried out for four weeks. ANOVA was used to test the observation data, and DMRT was used for additional testing. The pakcoy and samhong plants' plant height were best achieved when an AB-Mix concentration of 1200 ppm was used.
