Abstract

Water clover is an important weed that causes a decrease in rice yields by 15-42%. This study examined the effects of water clover density andNPK fertilizer application on rice yields. This study was arranged in a complete randomized block design with two factors. The first factor was water clover density with three levels, consisting of no water clover, one water clover, and two water clover. The second factor was the application of NPK, which was applied to the surface, submerged in 3, 6, and 9 cm—performed with three replications. Water clover density affected the number of rice panicles, the number of rice grains per panicle, the weight of 100 seeds, rice biomass, and water clover biomass. The application of submerged NPK affected rice biomass. The application of NPK on the surface reduced the highest rice biomass. Two water clovers per rice plant reduced the number of rice panicles by 39% compared to without weeds. Rice biomass decreased by 40% and 50% at weed density of one and two water clover weeds per rice plant, respectively. The higher the density of clover weeds, the higher the decline in harvest yields and the higher the biomass of clover weeds.

Abstract

The consumption of cayenne pepper tends to increase every year which is not balanced with the amount of national production, so a solution is needed so that the productivity of cayenne pepper can increase. Increasing productivity can be done through the use of organic fertilizers, namely GSA (Gibberellin Cytokinin Auxin). GSA stimulates the growth of roots, stems, leaves, branches, flower and fruit development, prevents aging, and helps seed germination. The purpose of this study was to determine the cultivation of cayenne pepper with the addition of GSA (Gibberellin Cytokinin Auxin) hormones and to analyze the farming efforts of cayenne pepper cultivation. This research was conducted in Pager Jurang Hamlet, Kepuharjo Village, Sleman Regency, Special Region of Yogyakarta. The research methods include field practice, observation and interviews. Conventional cayenne pepper cultivation activities on beds include preparation of planting media, sowing, planting, maintenance, harvesting, and post-harvest. Cultivation activities of cayenne pepper through the use of GSA hormones. Environmental conditions have a temperature of 22.5°C-28.4°C, humidity of 62.5%-85.2%, light intensity of 1845-3270 lux, altitude of 699 meters above sea level, and regosol soil type. The productivity of cayenne pepper is 62.26 kg during 14 harvests. The selling price of cayenne pepper tends to fluctuate by IDR 34,000/kg (April), IDR 23,000/kg (May), IDR 33,000/kg (June), and IDR 43,000/kg (July). Analysis of cayenne pepper cultivation farming can be said to be feasible or profitable with an R/C ratio of 1.17; B/C ratio of 0.17; and ROI of 17%. The farming ratio can be greater if the selling price is above the BEP price

Abstract

Acid soil is widely available in Indonesia and is suboptimal, so yields are low. The research examines the effect of antagonism and nitrogen fertilizer on peanuts' growth, nodulation, and yield in sour planting. This study used a factorial complete randomized block design with two factors. The first factor is the dose of Nitrogen fertilizer with four levels: 0, 50, 100, 150 kg.ha-1. The second factor is the source of rhizobium with three levels: without rhizobium, legin rhizobium dose ten g.kg-1 seed, and rhizobium from peanut plantations. They were repeated three times. Nitrogen 50 kg.ha-1 with the source of used peanut rhizobium showed the highest plant height, 15.73 cm. The combination of 100 kg.ha-1 of nitrogen with a source of used peanut rhizobium showed the highest number of plant leaves, namely 675.33 leaves. A nitrogen dose of 50kg.ha-1  produced the highest effective number of nodules and nodules, namely 363.00 and 19.33 nodules. The optimum nitrogen fertilizer dose is 44 kg.ha-1 for nodule growth. 50 kg.ha-1  nitrogen dose produced the highest number of pods and seed weight, namely 48.67 pods and 407.79 g of seeds. Nitrogen fertilizer at the correct dose can increase peanuts' growth, nodulation, and yield in acid soil. However, a dose that is too high may cause antagonism with the nodulation process and reduced yield.

Abstract

Background: Indigofera tinctoria, commonly known as true indigo, is a plant widely used in the textile industry for its natural indigo dye, which produces a rich blue color for fabrics. I. tinctoria, known for its natural bluish-purple dye, generates 10% dye and 90% waste during extraction, requiring effective waste management. This study aimed to optimize organic fertilizer and mycorrhiza doses from I. tinctoria  waste for enhancing soil fertility in arid regions. Methods: The study was conducted from May to December 2020 in Puron Village, Bulu District, Sukoharjo Regency. A factorial Completely Randomized Block Design (CRBD) with 2 factors was employed. The first factor consisted of 5 levels of I. tinctoria  organic fertilizer treatments: 0, 100, 200, 300, and 400 g per plant. The second factor included 3 levels of mycorrhiza treatments: 0, 10, and 20 g per plant. Variables observed included mycorrhizal infection on roots, plant growth rate, and yield (fresh leaf and shoot weight of I. tinctoria ). Data analysis utilized ANOVA at a 5% significance level followed by Duncan Multiple Range Test (DMRT). Results: The results indicated that organic fertilizer from natural dye waste at a dosage of 200 g per plant increased the percentage of mycorrhizal-infected roots and boosted shoot weight by 63.27% at 8 weeks after planting (WAP). Mycorrhiza at 10 g per plant increased mycorrhizal infection percentage and enhanced shoot weight by 45.98% at 4 WAP. The combination of I. tinctoria  extraction waste organic fertilizer at 200 g per plant and mycorrhizal at 10 g per plant showed interaction, significantly increasing the growth of root nodules of I. tinctoria by 84.04% at 12 WAP. Conclusion: The integration of organic fertilizer derived from indigo dye waste and mycorrhiza presents a promising strategy for enhancing I. tinctoria  growth and productivity. Novelty/Originality of this Study: This study is distinctive in its demonstration of the effective use of I. tinctoria  extraction waste as an organic fertilizer, aligning with zero-waste principles and contributing to improvements in plant growth and soil fertility. Furthermore, it investigates the synergistic effects of mycorrhizal associations on enhancing nutrient absorption and overall productivity of I. tinctoria , an aspect that has not been thoroughly explored in prior research.

Abstract

Desa Sambi, Kecamatan Sambirejo, Sragen terlatak pad aketinggian 191 mdpl dengan jumlah penduduk sebagian besar sebagai petani dan peternak. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk mengedukasi dan melatih masyarakat dalam pengelolaan limbah ternak menjadi pupuk organik padat melalui proses pengomposan. Desa Sambi memiliki potensi besar dalam sektor pertanian dan peternakan, namun limbah ternak yang dihasilkan belum dimanfaatkan dengan optimal. Penggunaan pupuk organik dari limbah ternak diharapkan dapat mengurangi ketergantungan terhadap pupuk kimia yang berdampak negatif pada lingkungan dan kesuburan tanah. Metode pengabdian sosialisasi, penyuluhan, dan pelatihan pengomposan aerob dengan melibatkan BUMDes Sejahtera dan Kelompok Tani "Sumber Rejeki" sebagai mitra. Hasil kegiatan menunjukkan peningkatan pemahaman dan kesadaran masyarakat terkait manfaat pengomposan limbah ternak serta teknik yang tepat dalam menghasilkan pupuk organik berkualitas tinggi. Masyarakat Desa Sambi menunjukkan antusiasme dan partisipasi aktif dalam kegiatan ini, yang diharapkan dapat berkelanjutan untuk mendukung pertanian berkelanjutan dan meningkatkan perekonomian desa. Namun, perlu dilakukan pemantauan lebih lanjut terhadap penerapan teknik pengomposan dan kualitas pupuk organik yang dihasilkan sesuai dengan standar yang berlaku
