Abstract

Cayenne pepper (Capsicum frutescens L.) is a commodity that often experiences price fluctuations due to a decrease in the supply of cayenne pepper amidst a large market demand. One of the factors causing the decrease in the supply of cayenne pepper is the environmental conditions that experience drought stress during the dry season. Osmopriming of seeds is one method that can be used to overcome drought stress. This study aims to determine the effect of osmopriming seeds using PEG 6000 on the germination and growth of cayenne pepper plants on drought stress. This study was experimental using a completely randomized design, with 2 treatment factors and 3 replications. The first factor was the application of priming at three concentration levels: P0 (0% PEG), P1 (12.5% PEG), and P2 (25% PEG). The second factor was drought stress treatment which consisted of 3 levels, namely: K1 (100% field capacity), K2 (75% field capacity), and K3 (50% field capacity). Data analysis used univariate analysis of variance and followed by DMRT (Duncan's Multiple Range Test) advanced testing with α = 0.05. The results showed that the application of 25% PEG priming gave the most optimal results on the performance of germination and growth of cayenne pepper plants, such as plant height, root length, root fresh weight, shoot fresh weight, root dry weight, and shoot fresh weight.

Abstract

The demand for pakcoy (Brassica rapa L.) a nutritious vegetable is increasing without being balanced due to the limited of agricultural land. The Wick system hydroponic cultivation technique can be a solution to increase pakcoy productivity. AB mix hydroponic nutrient solution is difficult to reach because it is expensive and has a negative impact on plants. It can be combined with rabbit urine LOF to provide essential nutrients for plants. This research aims to determine the effect of the combination of AB mix with LOF rabbit urine on the growth of pakcoy plants. The research design is CRD, 1 factor, 8 treatments, and 3 replications. Treatments include A1P0=AB mix 100% +0mL/L LOF rabbit urine, A1P1=AB mix 100% + 1mL/L LOF rabbit urine, A1P2=AB mix 100%+2mL/L LOF rabbit urine, A1P3=AB mix 100% +3 mL LOF rabbit urine, A2P0=AB mix 75%+0mL LOF rabbit urine, A2P1=AB mix 75%+1mL/L LOF rabbit urine, A2P2=AB mix 75%+2mL/L LOF rabbit urine, and A2P3=AB mix 75%+3mL/L L of rabbit urine.The addition of rabbit LOF gave the best results with AIP3 treatment on growth parameters, plant height, number of leaves, leaf area, fresh weight of shoots, and roots, dry weight of shoots and roots, respectively 27.41 ± 1.44 cm, 17.33 ± 0.95 pieces 632.89±228.20cm2, 61.88±13.42g, 1.648±0.374g, 3.132±0.614g, and 0.101±0.021g. The essential nutrient content of rabbit urine LOF increases the availability of internal nutrients which are influenced by metabolism, absorption capacity, water and sunlight.

Abstract

Limited agricultural land has caused a decline in the productivity of green mustard (Brassica juncea L.) as one of the nutritious vegetables that is widely consumed by the public. Cultivating vegetables using a hydroponic wick system is a solution to increase the productivity of green mustard. The expensive price of nutrient solutions can be combined with eco enzymes as a provider of essential nutrients for plants. This research aims to determine the effect of the combination of AB mix with eco enzyme on the growth of green mustard. The research was designed with RAL, 8 treatments, and 3 replications. Treatments include A1E0=AB mix 100%+0mL/L eco enzyme, A1E1=AB mix 100%+1mL/L eco enzyme, A1E2=AB mix 100%+2mL/L eco enzyme, A1E3=AB mix 100%+3mL eco enzyme, A2E0=AB mix 75%+0mL eco enzyme, A2E1=AB mix 75%+1mL/L eco enzyme, A2E2=AB mix 75%+2mL/L eco enzyme, and A2E3=AB mix 75%+3mL/L eco enzyme. The parameters measured were plant height, number of leaves, wet weight of roots and shoots, dry weight of roots and shoots, and leaf area. Data were analyzed using analysis of variance and DMRT testing with α=0.05. The combination of AB mix with eco enzyme had no effect on plant height, number and area of leaves, and wet weight of roots and shoots. However, the highest dry weight of roots and shoots in the A2E2 treatment showed significantly different results from the control treatment (A2E0). Eco enzymes act as nutrient substitutes which are influenced by sunlight, plant metabolism and water absorption capacity.
