The use of inorganic fertilizers has an important role in increasing plant growth and production. But it also causes various problems such as decreasing soil organic matter, soil acidity, soil degradation, nutrient imbalance and increasing environmental pollution. Therefore, it needs to be balanced with the provision of organic fertilizers. A field experiment was conducted to study the effect of application of various doses of inorganic and organic fertilizers on N, P, K nutrient uptake and maize plant growth. The experimental design used was a randomized block design arranged in a factorial manner consisting of two factors. The first factor is the dose of inorganic fertilizer (A): 0, 150 and 300 kg ha-1 phonska and the second factor is organic fertilizer plus (P): 0, 10, 20 tons ha-1. The two factors were combined and each treatment combination was repeated three times. The data obtained were analyzed by analysis of variance at the 5% level of significance. The results showed that there was no interaction between the application of inorganic and organic fertilizers on the growth and nutrient uptake of N, P and K. However, the application of inorganic and organic fertilizers had a significant effect on all tested agronomic traits except for plant height. Nutrient uptake of N, P and K also increased significantly due to the application of inorganic and organic fertilizers. The balance of inorganic and organic fertilizer application increases the availability of nutrients as well as the uptake of N, P, and K nutrients by maize plants.

Curly red chili (Capsicum annum L.) is widely cultivated us-ing inorganic fertilizers which causes high production costs. Chili is valued because of the level of spiciness. The level of spiciness of chili is determined by the level of capsaicin which is affected by nutrients in the growing media. The nutrient of the planting media can be fulfilled by degrading the growing media by microbes in organic fertilizer. One type of organic fertilizer containing degrading microbes is biofertiliz-er. Biofertilizer and biogas sludge is one of the organic fertilizers con-taining microbes and organic materials that are able to support nutri-ent levels of the planting medium. This study aimed to analyze growth parameters include chlorophyll content and measure capsaicin levels in curly red chili. Which given biofertilizer and biogas sludge in vari-ous dosage and determine the optimum dose of the fertilizer. The study was conducted at an agricultural demonstration plot in Wukirsari Vil-lage, Cangkringan, Sleman. The study design used RCBD (Randomized Complete Block Design), the data were analyzed by ANOVA (Analysis of Variance followed by Duncan’s Multiple Distance Test (DMRT) at the 95% confidence level. The highest growth parameters and capsa-icin content were obtained on curly red chili plants which were given biogas sludge 36 mL + biofertilizer 10 L / ha. The application of bi-ofertilizer and biogas sludge in various concentrations given has not been able to increase the average total chlorophyll content of curly red chili plants.

The purpose of this research was to examine the response of water spinach plants to the application of bioactive fermented liquid organic fertilizer on plant growth. This research used a method consisting of two treatments and one combination, namely a combination of watering and spraying treatments, as well as watering, spraying, and control. This experimen was conducted in the outdoor laboratory of SMKN 63 Jakarta, on land Kale plants. From this research, it was found that the combination of watering and spraying treatments was significantly higher and gave the best results compared to the watering, spraying, and control treatments. Based on the results of the study, it is known that there are differences in harvest age between the treatments of Watering, Spraying, Watering & Spraying and Control. The fastest harvesting age in the treatment of Watering & Spraying. Bioactive has a positive effect on vegetative growth and has a biopesticide effect. This is presumably because Bioactive is made from organic material/agricultural waste by aerobic and anaerobic fermentation methods so that from the fermentation it produces amino acids and alcohol which have an effect against plant vegetative growth and pests that often appear on crystal guava and breadfruit plants. During and after the experiment, no signs of pests or diseases were seen on the plants.

The challenges of food shortages and environmental pollution require the development of safe and effective alternatives to chemical fertilizers. Two field experiments were conducted during the summer season of 2019/2020 in two locations on a private farm to evaluate the performance of three potato cultivars (Sponta, Cara, and Elbieda) under different fertilizer treatments. The experiment was laid out in a split-plot design replicated thrice. The main plots had three potato cultivars, while the sub plots were comprised of seven fertilizer treatments. The results showed that the highest vegetative growth characters, viz. plant height, leaf chlorophyll index, and plant dry weight were produced by Sponta, followed by Cara, while the lowest growth attributes were recorded in Elbeida. Compared to the NPK inorganic fertilizer, organic fertilizers significantly improved the vegetative growth characteristics of potato in all treatments. Among the organic treatments, the highest growth parameters were recorded with the application of mixed organic fertilizer, vermicompost, and Azollapinnata (T1). The highest yield, viz. tuber yield, number of tubers per plant, and tuber weight, and yield quality characteristics, viz. total carbohydrates, starch, and TSS, were also recorded in T1. Our results demonstrate that the Sponta cultivar grown with the application of mixed organic fertilizer, vermicompost, and Azollapinnata (T1) produced the highest growth, yield, and quality of potato tubers. Thus, we recommend this treatment combination as a sustainable agricultural practice for potato production in similar areas

Second Year

Container production of recently-developed and popular Kalmia latifolia cultivars has not been fully optimized. A study was conducted using six cultivars grown in full sun, 40% shade or 60% shade. Under 60% shade, plant height was reduced slightly, but shading, at either 40% or 60%, had no significant effect on all other measured growth parameters. Plants were too young to set significant numbers of flower buds, so the study will be continued a second year to quantify the effects of shade on flower bud set. Foliage color was measured using a Minolta CR-200 Chroma Meter. As shading increased, hue angle increased and the chroma and value of the color decreased, indicating that shading produced greener (less yellow), darker and duller foliage colors. Foliar chlorophyll content increased with increasing shading. Higher foliar chlorophyll content correlates with greener leaves in shaded treatments and is likely contributing to the green color. Using moderate levels of shade over container-grown Kalmia could allow growers to produce greener, more marketable plants without sacrificing plant growth.
