Abstract

Horticulture plant is essential component of agricultural development. It brings benefits products horticulture meet their food needs , aesthetic and to maintain health and environment. Climate change and the limited resources land causing loss for farmers food crops and horticulture. The purpose of drafting this paper is to inform the utilization of technology greenhouse and hydroponics as solutions to deal with climate change in the cultivation of plants horticulture. To get the result harvest season which is satisfying in the cultivation of plants horticulture , need to pay attention to environmental factor growing plants. The utilization of greenhouse in the cultivation of plants is one of a manner to give the environment that were more accessible for the condition of optimum position for the growth of plants. The use of hydroponics in cultivation crop can be implemented in greenhouse to keep the growth of plants optimally and protected from outside influences

Abstract

Nutrients or nutrients are important factors for plant growth which can be likened to food substances for plants. One of the factors that support plants to grow and produce optimally is the availability of nutrients in sufficient quantities in the soil. The elements N, P and K, have a very important role in plant growth and production. The purpose of the preparation of the paper is to provide information about efforts to improve efficiency and availability of nitrogen in the soil and nitrogen uptake in lowland rice plants (Oryza sativa L.) Nitrogen has a role as a constituent of enzymes which plays a large role in plant metabolism but is relatively not available to plants. The efficiency of the use of Nitrogen (N) fertilizer in lowland rice can be maximized by way of 1) timely fertilization, 2) planting superior varieties that are responsive to the administration of Nitrogen (N), 3) improving cultivation techniques, 4) regulating the timing of Nitrogen fertilizer (N ) the right during the growing season with Leaf Color Chart (LCC) or Leaf Color Chart (BWD) and 5) NPK fertilization simultaneously. Efforts to increase the availability of nitrogen in the soil and uptake in wetland rice can be done by adding high-quality organic matter, the use of Azotobacter isolates as biological fertilizers to reduce the decrease in soil health due to the input of synthetic chemicals.
