Abstract

Cayenne pepper (Capsicum frutescens L.) was a plant that has high economic value. The application of phosphate fertilizers in inorganic forms is not friendly to the environment and is slowly available to plants. This research was carried out from October 2019 to January 2020 in Pancot Village, Kalisoro Village, Tawangmangu District, Karanganyar Regency with an altitude of 1200 meters above sea level and Andisol soil type. This study used a completely randomized design with two treatment factors (factorial), namely the first factor is the dose of fast soluble phosphate fertilizer namely 0 kg/ha (no SP36 fertilizer), 150 kg/ha (one application), 150 kg/ha (3 times application), 100 kg/ha (3 times application), and 50 kg/ha (3 times application). The second factor is the dose of chicken manure consisting of 2 levels, namely 0 tons/ha (no chicken manure), and 40 tons/ha. Parameters observed were plant height, flowering age, fresh weight of the plant, number of branches, and number of fruit per plant. The results showed that fast soluble phosphate fertilizer had a very significant effect on plant fresh weight and fruit number. Manure treatment has a significant effect on the parameters of plant height, fresh weight of the plant, total fruit per plant. The interaction of fast soluble phosphate fertilizer and manure had a significant effect on flowering age, fresh weight, and the number of fruits per plant. The best results were in the interaction of fast soluble phosphate fertilizer with a dose of 50 kg/ha and 40 tons/ha of manure.

Abstract

Sediment deposition in the upstream river areas can cause drought and disrupt agricultural activities. This study aims to analyze the potential for drought in the Keduang Sub Watershed based on the Land Map Unit. The Keduang Sub-Watershed area has high potential for the development of agricultural land for food crops, but is not free from the potential for drought. The study was conducted using a soil survey method that was strengthened by soil sampling and laboratory analysis. Parameters for determining soil damage that causes the potential for land drought include soil physical properties, namely specific gravity, structure, soil color, porosity, permeability, slope, and soil type. The results showed that the potential for drought at the research location was still high. This is influenced by the level of soil damage that varies from low, medium to high. Land drought can be an obstacle to agricultural activities, and improper land management can worsen the situation. Conservative actions to overcome this problem include the addition of organic matter, crop rotation, application of soil cover or mulch, and processing agricultural land according to the contour direction. These activities are expected to overcome soil damage so that the potential for drought can be overcome. Keywords: Conservation activities, Land drought, Physic soil properties, Soil damage.

Abstract

Termites function as soil engineers and play a crucial role in the decomposition of organic matter. This study was conducted in the Alas Bromo Educational Forest under pine stands of various age classes. The objective of the research was to investigate the influence of termite activity on soil fertility, as indicated by the levels of soil organic matter (SOM), soil organic carbon (SOC), and soil pH. The method employed involved baiting pinewood stakes placed in polyvinyl chloride pipes (PVC) to assess termite activity, which was evaluated based on the level of damage to the stakes and classified into damage classes. The stakes used were made of pine wood, similar to the species of the overlying stands. This study identified four termite genera in the Alas Bromo area: Macrotermes, Microtermes, Odontotermes, and Schedorhinotermes. The findings revealed significant differences in SOM and SOC across the stake damage classes within each stand. In general, the highest values were observed in soils with the highest levels of termite activity, as reflected in damage class 4. However, soil pH values did not show significant differences across the varying levels of termite activity. These findings highlight that termites, as soil engineers, play a vital role in enhancing soil fertility and hold promising potential for application in the pursuit of sustainable agriculture.

Abstract

The ever-increasing demand for soybeans has not been matched by increased yields. This is partly due to farmers not fertilizing properly. Many farmers apply urea, SP36, KCl, or compound NPK fertilizers at doses that are inappropriate for the plants' needs. Many even fertilize haphazardly. Appropriate fertilization methods are needed. This study aims to determine the effect of some of fertilization methods on soybean growth and yield on Alfisol. This study used a completely randomized block design (RCBD) with five treatments and five replications. PT0 (no fertilizer), PT1 (Farmer's Method: Urea, SP36, and KCl), PT2 (Balanced Fertilization Method: Urea, SP36, and KCl), PT3 (Farmer's Method: NPK Compound Fertilizer), PT4 (Balanced Fertilization Method: NPK Compound Fertilizer). The results of this study show that inorganic fertilizers given in a balanced manner can increase soybean yields from 2.28 g/plant to 13.82 g/plant. The results of this study indicate that the best treatment method, PT2 (Balanced Fertilization Method: Urea, SP36, and KCl), is able to support plant growth and increase soybean yields.

Abstract

This study aims to assess the impact of Organic FertilizerPlus on soil fertility status, nutrient uptake, and soybean yield in Alfisol. The research employs a randomized complete group design (RCGD) with a single factor, consisting of P0 (Control), P1 (Cow dung, 5 tons ha-1 + Zeolite dose of 2.5 tons ha-1), P2 (Cow dung, 5 tons ha-1 + Zeolite dose of 5 tons ha-1), P3 (Cow dung, 5 tons ha-1 + Dolomite dose of 2.5 tons ha-1), P4 (Cow dung, 5 tons ha-1 + Dolomite dose of 5 tons ha-1), and P5 (Cow dung, 5 tons ha-1 + Zeolite dose of 5 tons ha-1 + Dolomite dose of 5 tons ha-1), repeated four times. The results indicate that the application of Organic FertilizerPlus enhances soil fertility status (pH, organic C, CEC, and available P), with the highest values observed in treatment P5, including pH (6.70), soil organic C (6.28 g.kg-1), cation exchange capacity (CEC) (6.85 cmol.g-1), and available P (2.63 mg.g-1). This leads to increased phosphorus uptake, consequently improving soybean yields. The highest soybean yield is achieved by applying Organic FertilizerPlus (P5) at 2.17 t.ha-1.

Abstract

The phalaenopsis hybrid has become an economically important flower in the horticultural sector. Phalaenopsis Fuller's Pink Stripe Orchid is a hybrid orchid resulting from a cross between Phalaenopsis Fuller's Pink Swallow and Phalaenopsis Fullers Black Stripe. Rice washing water (leri) is a residue that accumulates when washing rice. This residue is usually thrown away when it is actually rich in various organic and mineral compounds. Waste that is wasted in vain can be used as nutrients for the growth of orchid plants. This research was conducted to study the effect of dose and frequency of leri water spraying on the growth of Phalaenopsis Fuller's Pink Stripe orchid at the vegetative stage. This study consisted of 10 treatments, namely giving 5 ml of water every 2 days (L1), 10 ml every 2 days (L2), 15 ml every 2 days (L3), 5 ml every 4 days (L4). a dose of 10 ml every 4 days (L5), a dose of 15 ml every 4 days (L6), a dose of 5 ml every 6 days (L7), a dose of 10 ml every 6 days (L8), a dose of 15 ml every 6 days (L9), and control treatment (L0). Each treatment was repeated 3 times. Based on the results of the study, it are often all over that there's no important interaction between the dose and also the frequency of administration of Leri water on the growth and performance of the Phalaenopsis Fuller's Pink Stripe.Keywords: Rice Wash Water, Phalaenopsis Fuller's Pink Stripe, vegetative growth
