Abstract

The need for adequate nutrition for organic rice cultivation is very important. It is necessary to look for various sources of nutrients apart from organic fertilizers from rice straw compost and manure. Azolla water ferns and solid or liquid biofertilizers shoud be used as an alternative in the way to increase plant nutrients in organic rice cultivation in paddy fields. This experiment aims to increase the yield of lowland rice plants which are cultivated organically for the first time through the application of organic fertilizer enriched with azolla and biofertilizers in the lowland rice fields of Inceptisols Jatinangor. The experiment was carried out at the Experimental Garden, Ciparanje, it’s belong to Faculty of Agriculture, Universitas Padjadjaran, Sumedang, West Java. The design used was a Randomized Block Design (RBD) with six treatments, namely organic fertilizer, organic fertilizer + Azolla, organic fertilizer + solid biofertilizer, organic fertilizer + Azolla + solid biofertilizer, organic fertilizer + liquid biofertilizer, organic fertilizer organic + Azolla + liquid biofertilizer. Each treatment repeated four times. The experimental results showed that the application of a combination of organic fertilizers and biofertilizers had an effect on lowland rice yields but had no significant effect on plant N content and N uptake of lowland rice plants in Inceptisols Jatinangor.

Abstract

Penggunaan lahan pertanian dengan status hara kurang optimal dapatmenghambat pertumbuhan tanaman, sehingga perlu upaya penambahan unsur hara ke dalam tanah tanpa menyebabkan permasalahan lingkungan. Salah satu cara yang dapat dilakukan adalah dengan memberikan pupuk organik berupa kompos. Melimpahnya volume limbah pertanian dapat dimanfaatkan sebagai bahan baku pembuatan kompos. Penelitian ini bertujuan untuk mengetahui pengaruh dari berbagai jenis kompos limbah pertanian dengan taraf dosis yang berbeda terhadap populasi Azotobacter sp., C-organik, N-total, Serapan-N, dan hasil pakcoy (Brassica rapa L.) pada tanah Incepstisol Jatinangor. Penelitian dilaksanakan di rumah kaca kebun percobaan Ciparanje, Kecamatan Jatinangor menggunakan Rancangan Acak Kelompok dengan 10 perlakuan tiga ulangan. Perlakuan terdiri dari: satu kontrol dan tiga taraf dosis dari setiap jenis kompos. Jenis kompos yang digunakan adalah kompos jerami padi, ampas tebu, dan tandan kosong kelapa sawit. Hasil penelitian menunjukkan bahwa pemberian kompos limbah pertanian berpengaruh nyata terhadap total populasi Azotobacter sp. dan hasil pakcoy. Parameter C-organik, N-total dan Serapan-N tidak berbeda nyata antar perlakuan dan kontrol. Pemberian kompos jerami padi 20 ton/ha merupakan perlakuan terbaik dalam menghasilkan 130,97 g bobot basah dengan 8,46 g bobot kering per tanaman pakcoy. Pemanfaatan limbah pertanian dapat menjadi alternatif yang ramah lingkungan dalam meningkatkan hasil tanaman pakcoy, walaupun hasil penelitian ini belum berpengaruh nyata terhadap C dan N.

Abstract

Attempt to increase soybean production while maintaining soil health can be done by utilizing biofertilizers. However, the application of biological fertilizers on Inceptisols which tend to be acidic often go to meet the problems in its effectiveness. So it is necessary to maintain the effectiveness of inoculants through the selection of appropriate carrier materials. The experiment aimed to determine the effect of the application of Phosphate Solubilizing Bacteria (PSB) in carrier materials from agricultural waste (molasses, coconut water, and bran) to increase BPF viability, growth and yield of soybean (Glycine max L.) on Inceptisols in Jatinangor. The experimental design used was a randomized block design (RBD) consisting of a control treatment (without BPF inoculant), BPF without organic matter; BPF combined with three types of organic matter (each: molasses, coconut water, and rice bran and their mixtures). Experimental results showed that coconut water and rice bran could potentially maintain the viability of the BPF population. Coconut water could significantly increase the number and weight of seeds per soybean plant, with an increase in yield of 41.176% and 18.823%, respectively. Coconut water is an organic substance that has the most potential as a stimulant  material compared with molasses or bran.ABSTRAK Upaya untuk meningkatkan produksi kedelai sekaligus mempertahankan kesehatan tanah dapat dilakukan dengan memanfaatkan pupuk hayati (biofertilizers). Namun aplikasi pupuk hayati pada Inceptisol yang cenderung masam sering mengalami kendala dalam efektifitasnya. Sehingga perlu upaya untuk menjaga efektifitas inokulan melalui pemilihan bahan pembawa yang tepat. Percobaan ini bertujuan untuk mengetahui pengaruh aplikasi Bakteri Pelarut Fosfat (BPF) dalam bahan pembawa dari limbah pertanian (molase, air kelapa, dan dedak) untuk meningkatkan viabilitas BPF, pertumbuhan dan hasil tanaman kedelai (Glycine max L.)  pada Inceptisols di Jatinangor. Percobaan dilakukan di rumah kaca kebun percobaan Fakultas Pertanian Unpad. Rancangan percobaan yang digunakan adalah Rancangan Acak kelompok (RAK) yang terdiri dari perlakuan kontrol (tanpa inokulan BPF), BPF tanpa bahan organik; BPF dikombinasikan dengan tiga jenis bahan organik (masing-masing: molase, air kelapa, dedak padi,  dan campurannya). Hasil percobaan menunjukkan bahwa air kelapa dan dedak padi berpotensi dapat mempertahankan viabilitas populasi BPF. Air kelapa dapat meningkatkan jumlah dan bobot biji per tanaman kedelai secara signifikan, dengan peningkatan hasil masing-masing sebesar 41,176% dan 18,823%. Air kelapa merupakan bahan organik yang paling potensial sebagai bahan stimulan dibandingkan molase maupun dedak. Air kelapa mengandung glukosa, fruktosa, dan sukrosa, asam glutamat dan asam aspartat yang dapat berperan dalam memacu aktifitas BPF.

Abstract

The Inoculation of beneficial soil microbes is an effective method for lowering doses of inorganic fertilizers. This study was aimed to observe and compare the effect of doses and formulas of Bacillus-coated NPK (BCN) and conventional NPK fertilizers on biomass, major macro-nutrient in soil and their uptake by shoots of lettuce (Lactuca sativa L.); as well as evaluate the potency of BCN for decreasing doses of NPK fertilizers. The greenhouse experiment was set up in a randomized block design with seven treatments and five replications. The treatments included one and a half doses of recommended NPK fertilizer and two BCN fertilizer formulas; control treatment was without any fertilizer. This experiment showed that NPK fertilizer had comparable effect with BCN on growth traits; but application of NPK and coated NPK had a potency to increase the fresh weight of lettuce up to 24-45% which was in line with the increase of shoot-to-roots ratio. The potassium (K) content in soil and their uptake in lettuce shoots depend on doses and type of NPK but Nitrogen (N) and Phosphorus (P) content in soil and in shoot were not determined by treatments. The results showed that the recommended NPK dose (200 kg/ha) for lettuce can be reduced up to 50%; moreover, 50% of BCN enabled to maintain the N, P and K uptake as well as the lettuce yield.

Abstract

Inceptisols have problem in phosphate availability. Soil P content is very low available to plants because it is bound by soil colloids. One of the efforts to increase the P nutrient in the soil in a sustainable way by using P-Solubilizers that can dissolve phosphate in the soil so that it is available for plants. The purpose of experiment was to determine the effect of the combination dose of kaolin based P-Solubilizer and P fertilizer for improving P availability, P uptake, phosphatase, and maize yield on Inceptisols. The kaolin-based P-Solubilizer was used a consortium of phosphate solubilizing microbes (PSM) consisting of Bacillus subtilis, Burkholderia cepacea, Pseudomonas mallei, and Trichoderma asperellum. This experiment was conducted in the experimental field of the Laboratory of Soil Chemistry and Plant Nutrition, Faculty of Agriculture, Universitas Padjadjaran, Jatinangor, from July to December 2021. The experiment used a randomized block design (RDB) method with nine treatments and three replications, with details of 0 P-Solubilizer + 0 P-fertilizer; 100% P-fertilizer; 100% P-solubilizer; and combination 50%, 75 %, 100%, and 150% P-solubilizer with 50%, 75%, and 100% P-fertilizer. P-solubilizer 100% recommended dose 50 kg ha-1 and P-fertilizer recommended dose 100 kg ha-1. The results showed that the dose of 100% P-Solubilizer (50 kg ha-1) + 75% P (75 kg ha-1) showed the best results in increased P-availability (346,93%), P-uptake (312,5%), Phosphate activity (33,5%), and maize yields (48,09%) compared to without application of P-solubilizer and P-fertilizer. This consortium isolate could be developed as a P-Solubilizer with the ability to increase the efficiency of P up to 25%.

Abstract

Urea fertilizers and biofertilizers play an important role in potato (Solanum tuberosum L.) cultivation, but urea fertilizers are volatile and leach out easily that reduce their effectiveness. Urea coated with beneficial bacteria-enriched organic matter is expected to increase nitrogen used efficiency. The purpose of the experiment was to determine the ability of bacterial-coated urea (BCU) included Bacillus and Azotobacter to improve the growth, nutrient status and yields of potatoes grown in field; as well as to reduce urea dose. The experiment was setup in randomized block design with five treatments and six replications. The treatments were four combinations of the dose and formulation of BCU; and conventional urea fertilizer as control treatment. Application of both BCU formulation increased plant height as well as N and P uptake particularly when the recommended dose was used.  In contrast, the doses and formulation of BCU did not affect chlorophyll content. Application of BCU-A or BCU-B at the rate of 200 kg/ha increased tuber weight by 59% and 81% respectively.  Both high and low dose of BCU did not reduce the vegetative growth and yield compared to the plants fertilized with conventional urea. This experiment showed that BCU is considered to reduce the rate of Urea in potatoes cultivation.
