Abstract

High demand for shallots needs to be supported by an increase of yield in each region. The use of high-yield cultivar is one of the ways that can be done to increase the productivity of shallot conducted. Bangka has a soil of the Ultisol type, so adaptive cultivars on the land are indispensable. The research was carried out at the Experimental and Research Garden of Universitas Bangka Belitung. This study aims to determine the potential yield of onions and adaptive onion cultivars in Bangka Ultisol soil. The method used is a Randomized Block Design (RBD). Consists of 5 cultivars, such as Ambassador 1, Ambassador 2, Violetta, Keramat, and Maja Cipanas. Violetta is the most adaptive cultivar, that can grow to the height of the plant and the number of leaves that are almost equivalent to the onion plant planted in its native place. The onion cultivar that has the best yield potential to be grown in the Ultisol land of Bangka Regency is the Violetta cultivar because the weight of the bulbs and the number of bulbs produced are almost equivalent to the onion plants grown in their native area.

Abstract

Maize is one of the world's food crops besides wheat and rice, which is strategic to increase production. Ultisol is a type of soil spread across Indonesia with a land area distribution of 45,794,000 ha and has the potential to be used to increase corn crop production. This study aimed to elucidate the effect of the combination of coal fly ash (CFA) and chicken manure (CM) on P uptake and growth of maize grown on an Ultisol. The CFA doses applied were 0, 10 and 20 t ha-1 of coal fly ash, while the CM doses applied were 0, 10 and 20 t ha-1 of chicken manure. Observations included soil pH, total P, available P and P uptake by maize. The results of the study showed an increase in soil pH, but still showed a value below 5,5. The addition of coal fly ash and chicken manure as much as 20 t ha-1 provided the highest P availability and showed the highest P nutrient uptake value by corn crops. The application of coal fly ash and chicken manure can increase the availability of P better than without the addition of chicken manure. But, the application of coal fly ash up to 20 t ha-1 also inhibited the growth of maize by marking a decrease in the results of measuring the dry weight and height of maize plants.

Abstract

Peanut has long been cultivated in Indonesia and is generally grown on dry land. The continuous use of inorganic fertilizers can have a negative impact on the soil, so there is a need for environmentally friendly fertilizers such as biological fertilizers. This study aimed to elucidate the effect of mycorrhiza biofertilizer on the vegetative and generative growth of peanuts. The study was conducted in the experimental field of Cikabayan IPB with a three-factor Completely Randomized Design. The treatments tested were 1) control, 2) 100% NPK fertilizer, 3) 100% organic fertilizer, 4) 100% organic fertilizer + NPK, 5) 5 g mycorrhizae, 6) 100% NPK + mycorrhizae 5 g, 7) 100% organic fertilizer + mycorrhiza 5 g, and 8) organic fertilizer + NPK 100% + mycorrhiza 5 g. Parameters observed included plant height, number of primary branches, number of pods, pod weight, colonization or root infection, number and types of spores. The results showed that the application of NPK fertilizer + organic fertilizer + mycorrhizae 5 g could increase vegetative and generative growth in peanut plants. The treatment of NPK+ organic fertilizer + mycorrhizae 5 g (AOM) had a very high percentage of infection, which was 86.67%. The AOM treatment had a high number of spores, which was 32 spores and 3 types of spores were successfully associated, namely Acaulospora sp1, Acaulospora sp 2 and Glomus etunicatum.

Abstract

Rice is one of the food crops and commercial crops. Rice also has the potential to contribute significantly to increasing income and employment in rural areas. As indicated by rice imports from Thailand and Vietnam, national rice production has not been able to meet domestic demand. The objectives of this study were (1) to determine the actual and potential land suitability levels of rice plants in Luwu Regency and (2) to find out the limiting factors for actual and potential land suitability of rice plants in Luwu Regency. Evaluation of rice land suitability using the FAO method. Based on the limiting factors of land characteristics. The results showed that the actual land suitability of plants was marginal (S3fn) with the limiting factors for nutrient retention (organic C) and available nutrients (P2O5 and K2O). Efforts to improve the limiting factor can be made by adding 59.6 t organic matter ha-1, 332.6 kg P2O5 ha-1, and 98 kg K2O     ha-1 so that the actual land suitability of marginal (S3) becomes very suitable (S1).

Abstract

Clay minerals are an important indicator of soil plasticity, influencing clay activity. This study aimed to elucidate the effect of clay minerals, organic C and primary minerals on the Atterberg limit and clay activity. The study was conducted in the Kemuning sub-watershed, Jember, East Java. The study began by preparing a thematic map to determine sample points with stratified random sampling. They were taken as many as 35 disturbed soil sample points at 0-20 cm from the surface. Soil texture was determined using the pipette method, and organic C was determined by the spectrophotometer method. The liquid limit and plastic limit were used to determine the plasticity index. A microscopic analysis of sand mineralogy was carried out to compare activity values with a magnification of 20-40 times to assess the primary soil minerals. The results showed that clay and C-organic affect fluidity, plastic limit, and plasticity index. The presence of andesine, albite, olivine, and orthoclase in the sand fraction and the low clay activity indicated that kaolinite dominated the study area, with smaller amounts of illite and halloysite.

Abstract

The price of the AB mix is relatively high, so it needed to find another alternative with a more economical price. One of the alternatives is Liquid Organic Fertilizer (LOF). This study aimed to know the quality of LOF made from banana peels and chicken egg shells, the effect of LOF on the water spinach grown in the hydroponic wick system, and the possible use of LOF as a substitute for AB mix. The experiment consisted of three stages. The first stage was the nutrient analysis of raw materials. The second stage was the production of LOF and nutrient analysis. The results of fermented fertilizers are called POC PT. The third stage was an experiment on water spinach in a hydroponic wick system. The experiment used a completely randomized design with five fertilizer treatments, namely P0 (control), P1 (AB mix nutrition), P2 (LOF PT 150%), P3 (LOF PT 100%), P4 (LOF PT 50%) in three replications. The results showed that LOF, which was fermented for three weeks, had a low nutrient content and was below the Ministry of Agriculture standard. The available N content in POC PT was low, so Ca(NO3)2 fertilizer was added to POC PT. The LOF PT treatment had higher plant growth parameter than the control treatment. Thus, the treatment of LOF PT could not substitute AB mix.

Abstract

The yield of irrigated paddy rice in Sri Agung Village has decreased. In the last four years, the increase in the addition of input units (fertilizers) has not been followed by an increase in economic yields. This study aims to analyze the effect of organic fertilizers on soil fertility, such as pH, total N, organic C, available P and available K. The research was conducted in the rice fields of Sri Agung Village. Batang Asam area, West Tanjung Jabung Regency - Jambi. The research was conducted from April to September 2020. The study used a randomized block design with six treatments and five replications. The treatments tried were: Recommended Fertilizer (R), five types of organic fertilizer with a dose of 10 t ha-1 each, namely, Petroganik+R ( P1), Compost Solid Decanter + R (P2), Chicken Manure + R (P3 ), Cow Manure +R (P4) and Industrial Waste Compost + R (P5). The results showed that organic fertilizers significantly increased available K content of paddy soil but they did not significantly increase soil pH, total N, organic C and available P. The highest yield of dry milled grain (7.52 t ha-1) was obtained at +R (P1) Petroganic treatment.
