Abstract

Jack bean (Canavalia ensiformis L.) and velvet bean (Mucuna pruriens L.) are local legume species with significant potential as sources of plant-based protein. To date, both species have primarily been utilized as sources of animal feed, green manure, and cover crops. This study aims to evaluate the effects of NPK fertilizer on the growth and yield of the two legume species. The experiment was conducted in Nanggela Village, Mandirancan District, Kuningan Regency, from June to November 2024. The experimental design used was a Randomized complete block design with treatments combining legume species (Jack bean and velvet bean) with NPK fertilizer applied at rates of 150, 225, 300, 375, and 450 kg ha-1. The variables observed were plant height, number of leaves, stem diameter, root length, root volume, leaf area index, relative growth rate, net assimilation rate, number of pods per plot, number of seeds per pod, weight of 100 seeds, and weight of seeds per plot. The results showed that the combination of species and NPK fertilizer doses significantly affected the growth and yield of koro plants. The best results were obtained from the treatment of jack bean with a dose of NPK fertilizer of 300 kg ha-1.   ABSTRAK Kacang koro pedang (Canavalia ensiformis L.) dan koro benguk (Mucuna pruriens L.) merupakan spesies lokal yang memiliki potensi sebagai sumber protein nabati. Selama ini kedua spesies tersebut dimanfaatkan sebagai sumber pakan ternak, pupuk hijau, dan tanaman penutup tanah. Penelitian ini bertujuan untuk mengetahui pengaruh pupuk NPK terhadap pertumbuhan dan hasil dua spesies koro. Percobaan dilaksanakan di Desa Nanggela, Kecamatan Mandirancan, Kabupaten Kuningan pada bulan Juni sampai November 2024. Rancangan percobaan yang digunakan adalah Rancangan Acak Kelompok dengan perlakuan kombinasi antara spesies koro (koro pedang dan koro benguk) dengan dosis pupuk NPK (150, 225, 300, 375, dan 450 kg ha-1). Semua perlakuan diulang tiga kali sehingga terdapat 30 satuan percobaan. Variabel yang diamati adalah tinggi tanaman, jumlah daun, diameter batang, panjang akar, volume akar, indeks luas daun, laju pertumbuhan relatif, laju asimilasi bersih, jumlah polong per petak, jumlah biji per polong, bobot 100 butir biji, dan bobot biji per petak. Hasil penelitian menunjukkan kombinasi spesies koro dan dosis pupuk NPK berpengaruh nyata terhadap pertumbuhan dan hasil tanaman koro. Hasil terbaik diperoleh dari perlakuan koro pedang dengan dosis pupuk NPK 300 kg ha-1. Dalam budidaya koro pedang, disarankan untuk menggunakan pupuk NPK (16:16:16) dengan dosis 300 kg ha-1, sebagai upaya untuk menggantikan kedelai pada wilayah-wilayah di mana kedelai sulit tumbuh.   Kata kunci: Koro pedang, koro benguk, pertumbuhan, pupuk majemuk

Abstract

Abstract Background. The main agricultural product that yields rice as a primary food source in Indonesia is rice plants (Oryza sativa L. ). This crop is vital for fulfilling the country's food demands. A significant challenge to achieving food security and independence nationally is the reduction in productivity, which results from soil fertility loss due to the overuse of chemical fertilizers. Aims. To address these challenges, strategies have been put in place, such as incorporating organic materials and utilizing soil microbes, which can be included in contemporary agricultural practices. The use of Plant Growth Promoting Rhizobacteria (PGPR) is one method to enhance plant growth. This study aimed to investigate the influence of PGPR on the growth and yield of rice plants (Oryza sativa L). Methods. The study was conducted from April to August 2025 in Babadan Village, located within Cirebon Regency in West Java. The experimental design utilized a Group Random Design (RAK) featuring six different PGPR concentrations, tested four times, resulting in 24 experimental plot units: P0 (control), P1 (5 ml/l), P2 (10 ml/l), P3 (15 ml/l), P4 (20 ml/l), and P5 (25 ml/l). Observations included various metrics such as plant height, number of sprouts in each clump, leaf area, root volume, plant growth rate (LPT), number of productive sprouts per clump, length of panicles, total grains per panicle, the percentage of filled grains per clump, weight of filled grains per clump, weight of 1,000 grains, total weight of harvested dry grains per clump, total weight of harvested dry grains per plot, and weight of milled dry grains per plot. Result. The findings indicated that PGPR positively affected multiple growth and yield characteristics. Specifically, PGPR application significantly influenced plant height, root volume, the number of panicles per clump, length of panicles per clump, grains per panicle, the percentage of grains per clump, weight of grains per clump, weight of 1,000 grains, weight of harvested dry grains (GKP) per clump, weight of GKP per plot, and weight of milled dry grains (GKG) per plot. Conclusion. The highest yields of harvested dry grains (GKP) and milled dry grains (GKG) per plot occurred with the PGPR treatment at a concentration of 15 ml/l, resulting in 6. 13 kg and 5. 81 kg, respectively. Implementation. Farmers in Babadan Village can adopt the PGPR treatment at a concentration of 15 ml/l.

Abstract

The issue faced by rice farmers in Cirebon is the brown planthopper pest. Brown planthopper infestations can lead to crop damage of up to 40%, and many farmers experience crop failures. This research aims to determine the effect of the concentration of the active insecticide ingredients Nitenpyram + Pymetrozine in controlling the brown planthopper pest and the yield of rice plants (Oryza sativa L.) of Inpari 32 cultivar. The experimental site was at an altitude of approximately 3 meters above sea level. The experimental design used a randomized group design (RGD). There were 5 levels of insecticide concentration treatments and a control (no treatment), each repeated 5 times, resulting in 25 experimental plots. The treatment levels included A (Nitenpyram + Pymetrozine = 1 g/l), B (Nitenpyram + Pymetrozine = 0.75 g/l), C (Nitenpyram + Pymetrozine = 0.5 g/l), D (Nitenpyram + Pymetrozine = 0.25 g/l), and E (control). The experimental results show that the application of the active ingredient Nitenpyram + Pymetrozine effectively reduces the intensity of brown planthopper and other pest attacks on Inpari 32 rice plants, but it does not affect natural enemies. The Nitenpyram + Pymetrozine active ingredient does not cause harm to the rice plants themselves. Based on the data, the results for all concentration levels are relatively the same. However, there is the most efficient concentration, namely the treatment of the active ingredient Nitenpyram + Pimetrozin 0.25 g/l which is capable of producing dry grain of 12.43 kg/plot or the equivalent of 4.972 tonnes/hectare.

Abstract

The numerous benefits and uses of chilies have led to a constant increase in demand as the population of Indonesia grows. Anthracnose is a disease that often affects chili peppers and is caused by the fungus Colletotrichum gloeosporioides. Farmers typically use fungicides to control anthracnose. Common active ingredients applied for anthracnose control include Mancozeb, Chlorothalonil, Propineb, and copper hydroxide. The research was conducted in the village of Ambit, Waled District, Cirebon Regency, West Java Province. The study took place over three months, from July to September 2023. The research method used a Randomized Group Design (RGD) consisting of five treatments with different active fungicide ingredients and a control (without treatment), repeated five times, resulting in 25 experimental plots. The treatments were A (Copper hydroxide active ingredient), B (Mancozeb active ingredient), C (Chlorothalonil active ingredient), D (Propineb active ingredient), E (Control /no fungicide). The fungicide concentration used was 2 ml/liter. The experimental results showed that the various active fungicide treatments had a significant effect on the intensity of anthracnose disease (Colletotrichum gloeosporioides) and other diseases like gemini virus. The Chlorothalonil active ingredient showed the lowest intensity of disease anthracnose when compared to the other treatments, even with other active ingredients that were tested. Fungicide treatments had a significant impact on chili yields per plot compared to the control treatment without fungicide. The Chlorothalonil active ingredient treatment yielded higher chili harvest results compared to other treatments, reaching 15.97 kg/plot or 15.97 tons/ha.
