Pertumbuhan tanaman bayam horenzo (Spinacia orelacea L.) dengan pemberian nutrisi menggunakan ekoenzim

Horenzo spinach (Spinacia oleracea L.) is one of the vegetable commodities that is currently in great demand by the public, however the cultivation process is still very limited so it requires optimal cultivation methods. Ecoenzyme is an organic solution that can be used in horenzo spinach cultivation as a substitute for fertilizer, because it contains nutrients that plants need. The ecoenzymes used are sourced from vegetable waste (mustard greens and lemongrass) and fruit peels (pineapple, mango, banana, watermelon and orange). This research was conducted to examine the potential of ecoenzymes and obtain optimal concentrations of ecoenzyme administration for the growth of Horenzo spinach plants. There were 6 treatments in this study, namely without treatment as a negative control (E0), giving a mixture of white CNG and KNO3 fertilizer as a positive control (E1) and giving different doses of ecoenzymes, namely 1ml/l (E2), 5ml/l (E3), 10 /l (E4) and 15ml/l (E5). Observations were carried out for 42 days with the parameters observed, namely vegetative growth (plant height, leaf length, leaf width, number of leaves, root length, root volume and plant organ biomass) as well as the chlorophyll content of the leaves of the Horenzo spinach plant. The data that had been obtained was then analyzed by Post-Hoc Tukey test data which showed that treatment E1 had significantly different results from other treatments and treatment E5 was an ecoenzyme treatment that had the potential to increase the growth of horenzo spinach plants. The conclusion obtained from this research is that the highest dose of ecoenzyme is not optimal in increasing the growth of Horenzo spinach plants from all test parameters, however E5 treatment has the potential to increase the growth of Horenzo spinach

Analisis curahan tenaga kerja pria dan wanita dalam usahatani hortikultura di lahan gambut

Research was conducted to examine the contribution of male and female workers in horticultural farming on peatlands in Limbung and Madu Sari Villages, Sungai Raya District, Kubu Raya Regency. The aim of this research is to find out the characteristics of horticultural farmers on peatlands, find out the amount of labor men and women use in horticultural farming on peatlands and how big the difference is in the amount of labor between the two, and find out the distribution of men's and women's decision making in horticultural farming on peatlands . Regarding the use of plant varieties, types of fertilizer, specific uses, and marketing of agricultural products. Are men or women dominant in decision making activities? Determining the sample size uses a saturated sampling technique, that is, the total number of samples is taken. The sample in this study was the total number of farmers taken from two villages, namely Madu Sari and Limbung villages, namely 40 respondents. The data analysis method used is descriptive qualitative and quantitative. The research results show that the average time spent by male workers is 50.31 HOK/planting season or a proportion of 74.62%, while the average time spent by female workers is 17.11 HOK/season or around 25.38%. This shows that there is still a lack of female labor in horticultural farming. Women's involvement appears to be dominant only in post-harvest activities. Apart from that, based on the distribution of men's and women's decision making in determining plant varieties, use of fertilizer types, specific uses, and marketing of horticultural farming products, it appears that women's involvement is still very limited. Is privation in decision making still very dominant? This shows that there is a gender gap in decision making for productive activities

Effect of cutting age and auxin concentration on growth of pinto peanut (Arachis pintoi)

Background: Pinto peanuts (Arachis pintoi) are known as versatile cover crops for soil conservation, biomulch, and ornamental plants. These leguminous plants rarely produce seeds, so they are commonly propagated vegetatively, resulting in low efficiency of seedling production and availability of cuttings. The aim of this study was to determine the effect of cutting age and auxin application on the growth of pinto peanut. Methods: This experiment used a complete randomized block factorial design. The first factor was the age of the cuttings (stolons) with three levels (young, intermediate, old). Each cutting had three nodes, with young cuttings measured from the tip, intermediate cuttings measured from the fourth node, and old cuttings measured from the seventh node. The second factor was the concentration of the commercial auxin product ROOTONE F (0 ppm, 500 ppm, 1000 ppm, 1500 ppm, 2000 ppm). Findings: The results showed that the difference in cutting age significantly affected the number of leaves (at 10 and 50 days after planting), plant length (at 10 to 50 days after planting), number of branches (at 30 to 50 days after planting), and canopy area. Differences in auxin concentration only significantly affected plant length from 10 to 30 days after planting. The interaction between cutting age and auxin concentration was significant only for the number of leaves at 10 to 20 days after planting and plant length at 50 days after planting. Conclusion: The highest values for the observed parameters were consistently obtained by intermediate cuttings followed by tip cuttings, which are therefore recommended as planting material for pinto peanut propagation. Novelty/Originality of this article: This study uniquely determined the effectiveness of pinto peanuts cuttings based on internode length, revealing that intermediate cuttings are the best material for its propagation, especially when treated with specific auxin concentrations, consistently outperformed tip and old cuttings in promoting optimal growth, offering a practical strategy to enhance vegetative propagation efficiency
