Abstract

Soil fertility is a crucial factor determining the growth and yield of plants. The increase of nutrient content and availability in soil can be achieved by fertilization. A field experiment was conducted using a Randomized Completely Block Design (RCBD) with two factors and three replications in order to study the effects of Mixed Source of Fertilizer (MSF) application on the nutrient contents in Vertisol and its relationship to the growth and yield of mustard. The first factor was the three MSF formulas (F1, F2, F3) and second factor was the doses of MSF (0; 2.5; 5.0; 7.5; 10 Mg ha-1) applied to the soil. At the end of the experiment, the soil pH, CEC, organic-C, total-N, available-P and exchangeable-K contents were measured. The results show that there are no significant differences on the soil chemical characteristics, such as pH, organic-C content, available-P, exchangeable-K, -Ca and -Mg measured after application of different MSF formulas to the soil. Meanwhile, the increase of MSF doses applied to the soil significantly increases organic-C content, total-N, available-P and exchangeable-K in the soil. The significant increase of available-P (by 29.13%) and total-N (by 24.1%) occured after application of MSF at 5.0 Mg ha-1 and the increase of exchangeable-K (by 50%) is achieved after application of 7.5 Mg ha-1, in comparison to that without MSF application. The height and fresh weight of mustard increase in accordance with the increase of MSF doses applied. The application of 10.0 Mg ha-1 MSF results in the highest height and fresh weight of the mustard up to 63.9% and 620%, respectively. The height and fresh weight of mustard are positively correlated to the total-N, available-P and exchangeable-K in the soil. The MSF is an alternative fertilizer that can be used to improve Vertisol fertility and plant growth.

Abstract

Sandy soil has limitations factor in supporting plant growth such as low soil organic carbon (SOC), cation exchange capacity (CEC), macro-micro nutrient content, water retention capacity, and high permeability rate. To improve soil conditions, it can be done by adding mycorrhizae and soil amendments. This study aimed to determine the effect of mycorrhizae application and soil amendments on the P availability and P uptake of plants in sandy soil. The research was conducted in a greenhouse of Agricultural Faculty, Sebelas Maret University. Used a completely randomized design consisting of 2 factors. The first factor was mycorrhizae with 2 levels, namely without mycorrhizae (M0) and mycorrhizae with 6 spores/plants (M1). The second factor was soil amendments; without amendment (P0), cow manure 60 tons/ha (P1), rock phosphate 150 kg/ha (P2), and combination of cow manure 60 tons/ha and rock phosphate 150 kg/ha (P3). The results showed that the application of mycorrhizae and soil amendments significantly increased available P, SOC, CEC, P concentration, and P uptake. Interaction of mycorrhizae 6 spores/plant and rock phosphate 150 kg/ha was able to increase the availability of soil P up to 12.8 times, plant tissue P concentration up to 1.4 times, and P uptake up to 2.27 times compared to the control. Application of mycorrhizae 6 spores/plant and cow manure of 60 tons/ha gave the best results on SOC and mycorrhizae with a combination of cow manure and rock phosphate gave the best results on CEC.

Abstract

Salinity of soil and irrigation is a factor that may cause a decrease in shallot productivity, so it requires efforts with amendments. This research aimed to determine the effect of gypsum and zeolite amendments on soil and shallot growth with saline irrigation. A pot experiment was conducted in the field using a completely randomized design with three factors. The first factor was two soil types (Alfisol and Inceptisol); the second factor was three shallot cultivars (Brebes, Purbalingga, and Pemalang); and the third factor was two types of soil amendments. The results showed that gypsum and zeolite reduced pH, sodium adsorption ratio (SAR), electric conductivity paste (ECp) and Na of the soils studied. Gypsum and zeolite increased the uptake of N, P and K by shallot plants. The increase of N uptake by applying gypsum on Inceptisol was more effective to Brebes and Purbalingga cultivars than Pemalang cultivar. Gypsum increased the diameter and number of bulbs in Inceptisol. Zeolite and gypsum increased bulb weight of Purbalingga cultivar in Alfisol.

Abstract

One effort that can be done to improve soil fertility and crop yields is fertilization. Fertilization using a mixed source fertilizer (MSF) is an option to overcome the impact of inorganic fertilizer use and organic fertilizer drawbacks. This study aims to evaluate the effects of MSF application on the chemical properties of Inceptisol and rice yields. A field experiment was conducted using a completely randomized block design (RCBD) with two factors and three replications. The first factor was the three formulas of MSF (F1, F2, F3) and the second factor was MSF doses (0, 2.5, 5, 7.5, 10 Mg ha-1). The results show that there is no significant difference on the total soil N, available soil P, plant height and total number of tillers of rice plants applied with the three MSF formulas. The increased MSF doses applied significantly improve the soil chemical properties of Inceptisol and rice yields. The application of 10 Mg ha-1 MSF increases total- N (57.89%), available-P (29.13%), exchangeable-Ca and -Mg (117% and 250%, respectively), plant height (40%) and total number of tillers (43.2%) in comparison to those without MSF application. There are interaction effects between formulas and doses of MSF on the amount of exchangeable-K, organic-C content, and CEC of the soil and rice yields. The application of 10 Mg ha-1 MSF F3 results in better effects on the amount of exchangeable-K, organic-C content and CEC of the soil, and number of productive tillers and rice yields than the application of other MSF formulas. The MSF can be used as an alternatif fertilizer that can improve Inceptisol productivity.

Abstract

Pot organik berbahan dasar campuran jerami padi dan limbah daun bawang merah merupakan inovasi baru untuk memanfaatkan bahan tersebut yang melimpah di lingkungan. Desa Srigading merupakan sentra pertanaman padi dan bawang merah. Setiap musim panen tiba, limbah hasil panen tersebut dibuang begitu saja. Padahal biomassa ini bisa dimanfaatkan untuk pot organik. Pot organik dari limbah jerami padi dan daun bawang merah dapat lebih aman dan tidak membuat pencemaran tanah dan lingkungan. Limbah jerami dipilih karena mengandung selulosa dan lignin yang tinggi. Selulosa dapat membentuk ikatan yang kuat antar molekulnya. Kandungan selulosa yang tinggi tersebut menjadikan jerami berpotensi sebagai bahan pembuatan pot biodegradable. Selain itu jerami mengandung bahan organik yang berperan penting dalam merekatkan butiran tanah membentuk agregat tanah yang lebih mantap. Daun bawang merah diyakini mengandung zat kitin yang tinggi, sehingga berpotensi sebagai penahan air dalam pot. Selain itu jerami padi dan daun bawang merah merupakan bahan organik yang mengandung berbagai unsur hara yang lengkap. Sehingga selain sebagai bahan baku pot, jerami padi dan daun bawang merah juga berfungsi sebagai cadangan unsur hara untuk tanaman dalam pot. Kombinasi jerami padi dan daun bawang merah diharapkan mampu menjadi alternatif pot organik yang ramah lingkungan, murah serta mudah diadopsi oleh masyarakat. Berdasarkan hal tersebut, limbah jerami padi dan daun bawang merah mempunyai potensi yang cukup strategis untuk dimanfaatkan menjadi pot organic/biodegradable. Pengabdian ini bertujuan untuk memanfaatkan limbah jerami padi dan daun bawang merah menjadi pot organik yang murah dan mudah diterapkan dan untuk peningkatan perekonomian masyarakat setempat. Penyuluhan tentang manfaat jerami, daun bawang merah dan pupuk kendang sebagai bahan pot telah dilaksanakan pada tanggal 21 Juni 2019. Hasil menunjukkan bahwa peserta antusias mengikuti kegiatan penyuluhan dan praktek pembuatan pot organic berbahan dasar jerami padi, daun bawang merah dan lempung.

Abstract

Alfisols have low fertility, so fertilization is carried out to increase soil fertility and support the growth of maize plants. The continuous use of inorganic fertilizers in high quantities can cause land degradation, so it is necessary to reduce the amount by adding other fertilizers, such as organic fertilizers, as well as the relatively high price of inorganic fertilizers. This research was aimed to examine the potential of organic fertilizers in replacing inorganic fertilizers. The experimental design was a completely randomized block design with nine combination treatments of organic and inorganic fertilizers with three replications. The results showed fertilizer treatment ½ NPK + 1 PO affected and increased levels of organic C, CEC, base saturation, total N, and available P in Alfisols and maize yield. However, it did not significantly affect pH, base saturation and available S in Alfisols. The chemical properties of the soil had increased values ​​of 48%, 9.01%, 61.3%, and 134.5%, respectively. The treatment of ½ NPK + 1 PO  increased maize productivity by 47.76% compared to the control with the productivity of 12.7 t ha-1, which the results were not significantly different from standard NPK. Thus, the application of 10 t ha-1 of organic fertilizer has the potential to replace ½ doses of inorganic fertilizer.

Abstract

The higher national rice demand encourages various efforts to increase rice production. This increase in rice production occurs in line with increasing public awareness of healthy foods, especially organic rice. Rice field management with an organic system is expected to provide a higher yield and quality of rice. This study aims to determine the effect of the long-time application of an organic rice management system on rice yield and quality. Descriptive exploratory research is supported by laboratory analysis of samples of organic rice plants with three periods (10 years, 7 years, and 4 years), semi-organic and conventional. The parameters observed were dry harvested grain, dry milled grain, the weight of 1000 grains, unfilled grain, protein content, amylum, amylopectin, and reducing sugar. The most prolonged organic rice field management with the application of 10 years gives better results with a protein content of 6.14%, amylum 71.71%, and amylopectin 49.35%. While the application of organic farming for 7 years gives the highest rice yield, the difference is not confirmed with the application of organic 10 years, with the weight of dry grain harvest 10.44 Mg ha-1, dry milled grain 8.15 10.44 Mg ha-1, the weight of 1000 grains 24 g, and unfilled grain 3.8%.
