EFEK FITOHORMON PGPR TERHADAP PERTUMBUHAN TANAMAN JAGUNG (Zea mays)

Plant Growth Promoting Rhizobacteria (PGPR) is hyper Rhizobakteri growingplants, which are groups of beneficial bacteria that actively colonize rizosfir. Plantgrowth hormones will meet their needs through the ability to get from rizosfir and filosfiras a result of the activity of PGPR in synthesising fitohormon. In the rhizosphere zone,the interaction of plants with PGPR has a very important role in maintaining soilbiological environment. One of the most common ways how PGPR increase nutrientcapture by plants that alter plant hormone levels. The purpose of this article shows theeffect of PGPR on plant growth fitohormon corn. Some of the genus Pseudomonas,Azotobacter, Bacillus, and Seratia identified as PGPR fitohormon producer that canimprove plant growth and yield of maize

The Use of Bokashi to Enhance Agricultural Productivity of Marginal Soils in Southeast Sulawesi, Indonesia.

The yield of agriculture crops tends to be decreasing in many parts of world including in Indonesian farmers’ land.  One of the causes of the decreased yields is the reduction of organic matter in the soil. Peanut is one of the important crops in southeast Sulawesi and is usually intercropped with maize. However, the yield of peanut and maize crops were low as they were grown in marginal lands that have low nutrient contents, low CEC, high acidity, and low organic matter. The objectives of this paper were to summarize the results of our studies on the use of bio fertilizer bokashi plus fertilizer to improve peanut yields grown in marginal soil in southeast Sulawesi, Indonesia. The study also examined the agronomical performance of several local peanut varieties which had high adaptability to the local conditions and marginal lands. The results of this study demonstrated that application of mulch and bokashi increased maize and peanut production, seed dry weight and 100-seed weight. This practice has potentials to be applied in other agricultural lands of southeast Sulawesi region with similar soil and climatic condition to increase peanut yield, and promote the sustainable agriculture production of the region

Bioteknologi Pupuk Bokashi Plus dan Sistem Intercropping pada Tanaman Hortikultura

Tanaman hortikultura merupakan bahan pangan yang sangat dibutuhkan oleh tubuh karena menjadi sumber vitamin, mineral, protein dan karbohidrat. Komoditas hortikultura memiliki nilai ekonomis cukup tinggi, dengan tingkat permintaan yang terus mengalami peningkatan seiring dengan bertambahnya jumlah penduduk. Hal ini menjadikan komoditas hortikultura memiliki potensi pasar yang sangat besar, namun tidak didukung oleh peningkatan produksi. Hal tersebut diakibatkan sebagian besar budidaya hortikultura dilakukan pada lahan marginal dengan teknik budidaya yang tidak memadai. Kabupaten Muna, khususnya Kecamatan Watopute memiliki potensi luas lahan untuk pengembangan hortikultura, khususnya sayuran. Namun, lahan-lahan tersebut didominasi oleh lahan kering marginal yang perlu segera ditangani agar produktivitasnya meningkat. Solusi untuk permasalahan tersebut diantaranya adalah teknologi inovatif hasil penelitian dari perguruan tinggi berupa bioteknologi pemupukan yang memanfaatkan sumber-sumber daya lokal dan penerapan sistem intercropping. Bioteknologi pemupukkan berbasis organik seperti pupuk bokasi plus merupakan teknologi inovatif yang dapat meningkatkan ketersediaan produk pertanian khususnya hortikultura, sedangkan sistem intercropping, selain mampu meningkatkan efesiensi penggunaan lahan dan meningkatkan produksi tanaman per satuan luas lahan, juga mampu memperbaiki kesuburan tanah, dan meningkatkan ketahanan tanaman terhadap hama dan penyakit. Program Kemitraan Masyarakat (PKM) merupakan program yang sangat tepat untuk mendiseminasikan solusi dari permasalahan tersebut sehingga dapat diadopsi oleh masyarakat secara luas

Improvement in yield of peanut (Arachis hypogaea L.) with combination treatments of bio-organic fertilizers

Peanut is a plant food with high economic value because of their nutritional content, especially protein, and high fat.  The nut land needs from year to year continue to increase in line with the increase in number population, nutritional needs of the community, food diversification, and increasing feed and food industry capacity. The present study aimed to determine the effectiveness of bio-organic fertilizers in producing local peanuts (Wadaga) from Muna Island, Indonesia. The randomized block design (RBD) was done with 12 bio-organic fertilizer  treatments (T1 to T12)  based on arbuscular mycorrhiza fungi (AMF) and cow manure fertilizer (CMF). The variables were viz.  pod weight, total pod number, filled pod number, percentage of empty pods, seed number, the weight of 100 seeds, dry seed weight, and productivity were observed. The results of the study showed that the highest average pod weight  (55.0 g), total pod number  (50.3 pods), filled pod number  (46.3 pods), and seed number (84.3 seeds) occurred with the treatment of T8: A2B1 ( AMF 10 g per plant + CMF 3 kg per plot).  The highest average productivity was obtained with T3: A0B2  (without AMF + CMF 6 kg per plot)  as 3.97 tons ha-1.  The use of mycorrhizal fungi combined with organic fertilizers can improve the growth of peanut plants which has a positive impact on their production

The Effectiveness Of Pre-Planting Seeds Bio-Matriconditioning And Application Of Fertilization With Leisa Technique On Growth Of Areca Nut Seedling (Areca Catechu L.)

Areca nut is widely used as industrial raw material, both for health and cosmetics and as a source of renewable energy. This study aimed to examine the combination of seed bombatriconditioning and LEISA fertilization treatments that were effective in increasing the growth of areca nut seedlings. The research was carried out in the Wua-Wua Kendari Village, from March to July 2021. The study used a split-plot design with a completely randomized design (CRD). The main plot is seed biomatriconditioning treatment which consists of 3 treatments. While the subplots were fertilized with the LEISA technique which consisted of 6 treatments so that 18 treatment combinations were obtained with 3 replications. Observations were made on plant height, number of leaves, stem diameter, number of roots, wet weight and dry weight of shoot. Observational data were analyzed using analysis of variance, followed by the DMRT α0.05 if there was a significant effect. The results showed that seed biomatriconditioning treatment with rhizobacteria integrated with the LEISA technique was able to increase the growth of areca nut seedlings. The integration between L1R biomatriconditioning and the application of organic plus fertilizer + 100% inorganic fertilizer showed a better growth performance of areca nut on plant height, number of leaves, stem diameter, number of roots, wet weight and dry weight of betel nut which were significantly different with control and application 100% inorganic fertilizer, but not significantly different from organic plus fertilizer, organic plus fertilizer + 50% inorganic fertilizer and organic plus fertilizer + 25% inorganic fertilizer. As a conclusion, pre-planting seed treatment with L1R biomatriconditioning is very important to increase areca nut seed germination. To increase the growth of areca nut seedlings, further fertilization needs to be done with organic plus fertilizer or a combination of organic plus fertilizer + 25% inorganic fertilizer
