ABSTRACT Soybean (Glycine max (L.) Merill) is one of the most important food commodities after rice and corn in Indonesia, so it is widely consumed by the people. The need for this commodity is very high and has only met 34,74% of the needs due to low soybean production and productivity. This study aims to determine the effect of LOF concentration, NPK dose and the best combination for soybean…
ABSTRACT Chilli is one of the important horticultural crops, because it can be used as an industrial raw material and adds a spicy and delicious taste to food.capsaicin. Peatlands have not been used optimally, especially for horticultural crops because peat has many problems. Efforts that can be made so that the land can be used for chili plants is by assembling several superior chili varietie…
ABSTRACT Utilization of rice husk zeolite and dolomite (source of Ca and Mg) for the development of upland rice in dry land was one of the potentials to increase rice production. The aim of the study was to increase the growth and yield of upland rice (Oryza sativa L.) on podzolic medium which was applied to rice husk zeolite and dolomite. The research was conducted from June to October at the…
ABSTRACT Consumers wants vegetable plants to be cultivated naturally and healthily for consumption. This can be achieved through the technical cultivation of organic farming. The continuous use of inorganic fertilizers will actually cause a decrease in soil fertility. Efforts that can be made to reduce the use of inorganic fertilizers are using liquid organic fertilizer goat urine and steps to…
ABSTRACT Oil palm is one of the plantation crops which plays a very important role for Indonesia as an export commodity and income for the people of Indonesia. This year, Riau is targeted to carry out replanting of 26,500 hectares. If there are 136 plants in every hectare, then 3,604,000 oil palm seeds with good quality conditions are needed. Efforts to increase the growth of oil palm seedling…
ABSTRACT The research aims to study the interaction of organic matter with earthworms, the main effects of organic matter and earthworms on the growth and production of sweet corn plants. The research was in the form of factorial experiments arranged according to a complete randomized design. The first factor of organic matter consisted of 4 levels (no organic matter, solid, compost of empty o…
ABSTRACT The area of oil palm plantations in Indonesia is 14.663 million Ha and in Riau Province, it will be 2.860 million Ha in 2021, most of which have entered the replanting phase so good seeds must be prepared as an important factor to produce good oil palm seeds. Good oil palm seeds have one radicle and one plumule, but sometimes oil palm sprouts have more than one radicle and one plumule…
ABSTRACT The way to get superior varieties is by selection, namely through genetic parameters which include diversity, heritability and genetic progress. This study aims to determine the genetic diversity and heritability of the performance of several genotypes of tomato plants in the lowlands. This study used a randomized block design consisting of 7 treatments and 3 replications to obtain 21…

ABSTRACT Production of sweet potatoes in Riau Province has decreased from 9,667 tons in 2018, 8,021 tons in 2019, to 7,305 tons in 2020, due to a decrease in harvested area of 490 Ha in 2018, 483 Ha in 2019, and 371 Ha in 2020. To increase production, efforts that can be done is by expanding the planting area by utilizing Inceptisol soil. However, Inceptisol soil has constraints in terms of it…
ABSTRACT Peanut (Arachis hypogaea L.) is a legume plant belonging to the Fabaceae family. Peanut production has decreased from year to year. This is presumably due to improper cultivation methods and limited soil carrying capacity. Efforts made to increase peanut production are through organic and inorganic fertilization, namely by applying oil palm empty fruit bunches (OPEFB) compost and NPK …
