Ultisols that are utilised continuously, without paying attention to the management of organic matter and fertility levels, result in decreased soil productivity. To determine the best dosage of biomass, compost, and wet ash on Ultisol in the field laboratory of soil department on sweet corn crop production. To determine the production of sweet corn on the application of biomass, compost, and w…
Ultisol is a soil that is classified as having low fertility. Judging from its wide distribution, Ultisol soil has great potential to be used as agricultural cultivation land. This research aims to determine the effect and best dose of biomass, compost and wet ash application on N, P and K uptake in sweet corn plants in ultisol. This research was carried out in the Field Laboratory of the Soil …
In an effort to improve the growth of sweet corn (Zea mays saccharata Sturt) in Ultisol, it is necessary to conduct in-depth research on the use of various organic materials as soil condition improvement. In this case, biomass, compost, and wet ash are the organic materials used and are expected to improve the growth of sweet corn plants in Ultisol. The objective of this study was to assess the…
The use of ultisol for plant cultivation has obstacles in the form of low productivity and few nutrients. In order for ultisol productivity to increase, this can be done by increasing the availability of nutrients and improving the chemical properties of the soil by adding organic materials such as biomass, compost and wet ash. Sweet corn is a food that many people like because it has a sweet t…
This manuseript was written based on to increasing fertilily of Ultisol and the pot expcriment to study pattern of relationship between compos and P fertilizer dosage on soil pH, the availability and uptake P and yield of sweet corn planted inUltisol.This experiment was conducted in the glass house and then for soil and plantsample analyzed at the laboratory of soil Chemical, Biology and Fertil…
Pemanfaatan tanah yang kurang subur seperti Ultisol memerlukan berbagai masukan seperti bahan organik, pupuk dan pengelolaan yang tepat. Untuk itu, penelitian ini bertujuan untuk menentukan takaran dan kombinasi bokashi, dolomit dan pupuk NPK yang memberikan pengaruh terbaik terhadap respirasi tanah dan pertumbuhan jagung manis pada Ultisol. Penelitian ini dilaksanakan dari bulan Agustus sampai…
This study aimed to determine the optimal dosage of seaweed-based biostimulants on the gowth and yield of sweet corn plants (Zea mays saccharata Sturt.). The research was conducted at the Experimental Garden of PT Pupuk Sriwidjaja Palembang from August to November 2023. The method used in this study was a Randomized Complete Block Design (RCBD) with 5 treatments, each treatment repeated 6 times…
The main commodities in Indonesia are food crops, mainly peas (Oryza sativa L.) and corn. (Zea mays saccharata Sturt). Pests and plant diseases are considered a major problem in Indonesia's agricultural production system, causing loss of yields of up to 30% per year. The use of synthetic pesticides is thought to be more effective, simpler, and provides huge economic benefits. The research was c…
Corn (Zea Mays) is the second important food crop after rice. Corn becomes a strategic food as an effort to diversify food because it contains a source of carbohydrates such as rice, where many processed corn acyl in the form of flour is a food product. Corn production is increasing, this shows that the increasing national corn production target means trying to create new varieties of corn that…
