Abstract

Green mustard (Brassica chinensis L.) is widely cultivated commercially. The problem is that some farmers use self-propagated seeds with simple processing and storage facilities so that the quality of the seeds is not guaranteed and is low. Apart from seed quality, limited water, especially during cultivation in the dry season or on dry land, is also a limiting factor. Low seed quality can be overcome by invigorating seeds using the osmopriming method; water limitations can be overcome by periodically fulfilling field capacity water. This research aimed to measure and analyze the growth response and drought tolerance of green mustard plants in seed osmopriming treatments and setting water intervals to field capacity. The research was carried out at the Experimental Field and Plant Physiology Laboratory, Faculty of Agriculture, IBA University in Palembang, in October-December 2020. The research used a 5x3 Factorial Randomized Block Design, with 3 replications, so there were 45 experimental units. The first factor was seed osmopriming, O1= control (water), O2= CaCl2 1.5% - soaked 4.5 hours, O3=CaCl2 3%-soaked for 4.5 hours, O4=KNO3 1%-soaked for 5 hours, and O5=KNO3 1.5%-soaked for 5 hours. The second factor was watering interval to field capacity, P1= every 24 hours, P2= every 72 hours, and P3= every 120 hours. The research results showed that osmopriming produced values of germination power, vigor index, growth speed, growth simultaneity and maximum seed growth potential of 100%, and with fast and relatively the same germination age of 4.22 to 5.05 days after planting (dap). In plants 14 dap, osmopriming with 1.5% KNO3 and soaking for 5 hours produced plants with the highest height, number of leaves and root length. The interaction of osmopriming with intervals of water supply to field capacity every 24 hours and 72 hours produces plants with the highest height, number of leaves, root length and weight/yield. There was a decrease in plant growth and yield at the interval of providing water to field capacity every 120 hours. The drought tolerance of green mustard is in watering intervals to field capacity every 72 hours.

Abstract

The fluctuating and decreasing production of shallots impacts the national stock. Its cultivation using high inorganic fertilizers requires high costs, reduces soil fertility, and affects long-term production.  Efforts are needed to increase production at a lower cost, reduce the use of inorganic fertilizers, and be more environmentally friendly.  One of them is using eco-enzymes that can be used as fertilizers, soil conditioners, and as a source of plant nutrients.  This study aims to evaluate and analyze the effectiveness and potential of eco-enzymes to increase the growth and production of shallots, while reducing the amount of inorganic fertilizer.  The study used a Randomized Block Design, four replications. There were three levels of treatment: P1 eco-enzyme; P2 eco-enzyme + N, P, K fertilizer 50%; P3 N, P, K fertilizer 100%. Each treatment consisted of 8 experimental units, for a total of 96, with a dose of N= 150 kg urea.ha-1, P= 200 kg SP-36.ha-1 and K= 150 kg KCl.ha-1. Eco-enzyme was given every week with a concentration of 1 ml.l-1; half was given by spraying the plants and half by watering the media.  The results showed that eco-enzyme is effective and can potentially increase the growth and production of shallots and reduce the use of inorganic fertilizers N, P, and K by up to 50%. The eco-enzyme + 50% N, P, K fertilizer produced shallot with the highest number of leaves per bulb and clump, number of bulbs per clump, circumference of bulbs, weight per bulb, and weight of bulbs per clump.

Abstract

Sweet corn is a horticultural crop with high economic value and steadily increasing market demand. However, sweet corn productivity in Indonesia remains relatively low, ranging from 8 to 10 tons per hectare, well below its genetic potential of 12 to 15 tons per hectare. This low productivity is attributed to several factors, including soil fertility degradation caused by unsustainable cultivation practices, pest and disease infestations, and limited farmer access to quality agricultural inputs at affordable prices. Sweet corn plants respond well to inorganic fertilizers; however, long-term use of these fertilizers can degrade soil quality and fertility, reduce microbial activity, and increase production costs. Moreover, excessive reliance on inorganic fertilizers leads to soil nutrient imbalances, reduced organic matter content, and adverse environmental impacts. Therefore, efforts are needed to reduce this dependence, one of which involves utilizing eco-enzymes as an organic nutrient supplement. This study aimed to evaluate the growth and yield responses of Hybrid-F1 sweet corn plants to reduced NPK fertilizer doses, combined with eco-enzyme application via soil drenching and foliar spray. The study employed a Randomized Block Design with four replications and four treatment levels, comparing full NPK fertilizer doses, a 50% reduction in NPK fertilizer combined with eco-enzyme, and standalone eco-enzyme application. The results demonstrated significant improvements in fertilization efficiency, with the combination of a 50% reduction in NPK fertilizer and weekly applications of 1 ml/l eco-enzyme via soil drenching and foliar spray achieving optimal growth and production equivalent to full fertilization. Another important finding is that eco-enzyme can be used independently without inorganic fertilizers; plants still grew normally and produced ears, although yields were relatively lower. For best results, it is recommended to use a combination of a 50% reduction in NPK fertilizer dose and eco-enzyme application through both soil drenching and foliar spray. This approach not only reduces production costs by up to 50% but also promotes more sustainable and environmentally friendly cultivation practices.
