Abstract

This study aims to determine of knowing the effect of the intensity of sun radiation and the right nitrogen fertilizer on the growth of the highest chinese cabbage. The research has been carried out in Wirogunan Village, Kec. Purworejo Pasuruan City was conducted from September to December 2021. This study used a Divided Plot Design (RPT) which was repeated three times. The intensity of sun radiation is placed as the main plot (P) which consists of three levels: : 55% sun radiation intensity, : 65% sun radiation intensity, : 75% sun radiation intensity. Nitrogen fertilizer doses were placed as subplots (J) which consisted of three levels: : Nitrogen fertilizer dose 200 kg ha-1, : Nitrogen fertilizer dose 300 kg ha-1, : Nitrogen fertilizer dose of 400 kg ha-1. From the two treatments, 9 treatment combinations were obtained and each treatment was repeated three times to obtain 27 treatment combination units. The results showed that the treatment of 65% sun radiation intensity and nitrogen fertilizer 300 kg ha-1 resulted in the highest plant growth and yield. Chinese cabbage treatment with 65% sun radiation intensity and nitrogen fertilizer 300 kg ha-1 resulted in fresh weight ha-1 of 53,61 tons.

Abstract

Hydroponics is a plant cultivation technique that uses water as a growing medium. The acidity level (pH) of water is an important factor in the success of hydroponic plant cultivation. High water acidity (pH>8) can be controlled by adding acid solution to a pH level of 5.8-7.0. This research was conducted to examine the nutrient content of lettuce. The research used a Randomized Block Design with 9 treatments (3 types of water and 3 types of acid solution). The types of water used include Kebonsari well water, Bugul Kidul well water and Pasuruan city PDAM water. The acid solutions used include nitric acid, phosphoric acid and sulfuric acid. The results of the research show that adding acid solutions to all types of water produces different plant nutrient contents. The addition of nitric acid and phosphoric acid solutions respectively had a significant effect on the N and P nutrient content of lettuce plants. The addition of phosphate solution can be recommended as a pH lowering solution in hydroponic cultivation.

Abstract

The purpose of this study was to obtain the right dose of organic fertilizer combination of chrysanthemum flower waste and NPK Mutiara inorganic fertilizer to support the growth and efficiency of nutrient absorption levels of tomato meranti plants. The method used in this study was a complete randomized design (RAK) with 4 treatments and each treatment was repeated 6 time. The treatment made is P0: 500 kg ha-1 NPK Mutiara (100% NPK); P1: Dose of Organic Fertilizer Chrysanthemum Waste 15 Tons ha-1 + 25 % NPK; P2: Dose of Organic Fertilizer Chrysanthemum Waste 10 Tons ha-1 + 50 % NPK; P3: Dose of Organic Fertilizer Chrysanthemum Waste 5 Tons ha-1 + 75 % NPK. With observation parameters, namely plant height, number of leaves, leaf area, dry weight of upper plants, dry weight of lower plants, total dry weight of plants, leaf area index, net assimilation rate, and plant growth rate. The results showed that with the addition of organic matter of chrysanthemum waste fertilizer combined with NPK inorganic fertilizer was able to support the growth of meranti tomato plants in the vegetative phase of plants with a combined dose of chrysanthemum fertilizer 5 tons Ha-1 + 75% NPK showed the best results on plant height parameters, number of leaves and dry weight of plants.

Abstract

Demand for vegetable commodities, including carrots, is high due to the increasing population and increasing public awareness of nutritional value, the need for food consumption is also increasing. The purpose of this study was to obtain the right dose of combination of chicken coop organic fertilizer and pearl npk inorganic fertilizer to support the growth and yield of carrot plants. The method used in this study was a randomized group design (RAK) with 4 treatments and each treatment was repeated 6 times. The treatment made is P0: 100% NPK Mutiara (75 kg ha-1); P1: Chicken manure dose 20 tons ha-1 + 50 % NPK; P2: Chicken manure dose 25 tons ha-1 + 50 % NPK; P3: Chicken manure dose 30 tons ha-1 + 50 % NPK. Research results The results showed that dosing treatment of 30 tons ha-1 + 50% NPK Plants-1 can increase the growth and highest yield of carrot plants compared to other treatments.

Abstract

Soil quality assessment can be done by monitoring the dynamic conditions of various indicators that influence it. Measuring these indicators produces a soil quality index (IKT), which is a tool to evaluate the impact of land management practices (Mas'udi et al., 2021). This research aims to determine the distribution of the soil quality index on shallot (Allium fistulosum L) agricultural land in Tosari sub-district, Pasuruan district, East Java. The research was carried out in Tosari sub-district, Pasuruan district at an altitude of 1700 meters above sea level. In September 2023 – January 2024. This research uses a purposive sampling method for taking soil samples. Next, it was analyzed in the laboratory for texture, volume weight, porosity, C-organic, pH, P-available, K-exchangeable and the rooting depth was measured. The soil quality index is calculated using the criteria of Mausbach and Seybold (1998), which can be adjusted to field conditions using the Minimum Data Set (MDS). Based on the research results, it shows that there are differences in the Soil Quality Index on Onion Leaf land in several villages in Tosari sub-district. Leek fields in Tosari sub-district have two criteria, namely medium and good criteria. Tosari Village, Ngawidono Village, Mororejo Village and Kandangan Village are classified as Good (B) while Podokoyo Village is classified as Medium (S).

Abstract

Manure is an organic fertilizer with adequate nutrients to enhance soil quality and support plant growth. In Sebalong Village, Pasuruan, cow dung is used directly without processing, reducing its effectiveness. This study aims to evaluate different manure processing methods to optimize its use. Conducted in Sebalong Village (October–December 2024), the research employed a Completely Randomized Design (CRD) with four treatments and four replications: Method 1 (Aerobic composting with tarpaulin), Method 2 (Aerobic composting burned + composter), Method 3 (Anaerobic composting + composter + EM4), and Method 4 (Anaerobic composting burned + composter + EM4). Parameters measured included temperature, humidity, pH, and nutrient content (N, P, K, organic C). Results showed that composting methods significantly affected compost quality. Method 4 (anaerobic composting with burning, composter, and EM4) yielded the best results, with organic C (18.66%), BO (32.10%), C/N ratio (7.40), N (2.52%), P (2.42%), and K (2.48%). This method proved most effective in enhancing nutrient levels, suggesting its potential for optimal organic fertilizer production in Sebalong Village.
