THE USE OF HYDROPONICS SYSTEM IN GROWING PLANTS

-------

Plants needed sources of food and energy such as sunlight, air, water and soil to be able to grow efficiently. The macronutrients and micronutrients nutrients coming from these sources help plants to flourish. Those nutrients are all can be found in soil but not in water. As it generally knows, plants grow most efficiently and effectively in soil. Soil is an essential element that the plant needs to survive. It is rich in nutrients which are the key elements in plant's growth and helps to increase vigour and disease resistance of the plant. Water, on the other side, has also an important role in flourishing plants. Without the presence of water, plants might droop and with too much amount of water, plants might drown and die. According to Science Buddies (2020), plants can survive without being planted in soil. Plants can also grow not in soil but in nutrient-rich water. The process of growing plants in water is called hydroponics. It comes from the Latin words "hydro" which means "water" and "ponos" which means "work". In this research, the researchers will use hydroponics system to inspect its effectiveness and productivity in growing variety of plants. The researchers will also use the traditional way of growing plants to show its comparison and differences.

According to Szczepanski (2015), Hydroponics is the act of growing plants without the use of soil. When growing plants in soil, water serves to make nutrients in the soil soluble and provides oxygenation for the plant's roots. In Hydroponics, however, the nutrients are instead made available directly in the water. In the most abstract sense, a hydroponics system requires a nutrient rich water supply, a means of oxygenating the water supply, and a means to transport the water to the plants. Since nutrients can be expensive, typical hydroponics systems are recirculating – the runoff from transporting water to the plants returns to the original water source. In the following, we discuss the main parameters that should be considered in a hydroponics system. This description is not intended to be complete, but rather gives an overview of the parameters that are most likely to affect a hydroponics system.

Harvey added that there is disclosed a structure for supporting the growth of plants, comprising a flexible tubular element in the wall of which slits are provided. Closure means define with the tubular element an elongated enclosed area that is filled with a fluid and root permeable material for supporting the roots of plants. A fluid nutrient is supplied by a pump to the material. The tubular element may be suspended from one of its ends and supplied at the upper end with the fluid nutrient to support plant growth through the perforations from the particulate material (1991).

According to King (2013), Hydroponics is a strategy for developing plants by giving mineral supplements from mineral supplement answers for plant roots rather than from soil. By and large, there are two primary sorts of aquaculture—arrangement culture aqua-farming and medium culture tank-farming. Arrangement culture aquaculture doesn't utilize a strong medium or substrate for the roots, though medium culture tank-farming incorporates a strong medium or substrate for the plant roots. Strong medium societies are for the most part classified by the sort of strong medium utilized, which comprehensively incorporates sand culture, rock culture, and rock fleece culture. Commonplace media utilized for strong medium aqua-farming societies incorporate the accompanying: (I) Diahydro, which is normal sedimentary stone that involves fossilized remaining parts of diatoms; (ii) Expanded dirt, which contains mud pellets that are discharged in furnaces to venture into permeable particles; (iii) Coir or coco peat, which is the extra material after the filaments have been taken out from the peripheral shell of the coconut; (iv) Mineral fleece, which incorporates strands produced using minerals or metal oxides, including fiberglass, fired filaments, and rock fleece, otherwise called stone fleece, which is an inactive substrate made by turning liquid stone or magma into masses of fine, entwined strands; (v) Perlite, which is volcanic stone that has been superheated into exceptionally lightweight, extended glass rocks; (vi) Vermiculite, which is another mineral that has been superheated to grow it into light stones; (vii) Sand; (viii) Gravel; (ix) Brick shards; and (x) Polystyrene.

Hydroponics development frameworks are a helpful stage for concentrating entire plant physiology. Nonetheless, they found through testing frameworks as they are depicted in the writing that our analyses were much of the time puzzled by factors that influenced plant development, including algal defilement and hypoxia. They likewise found the manner by which the plants were developed made them ineffectively agreeable to various normal physiological examines. They present an enhanced plant aquaculture culture framework that can be rapidly and inexpensively built, and delivers plants with comparative development energy to soil-developed plants, yet with the benefit of being a flexible stage for a bunch of physiological and atomic natural estimations on all plant tissues at all formative stages. They present 'tips and stunts' for the simple selection of this tank-farming society framework (Conn et al., 2013).

According to Trellez & Merino, Hydroponic crops harvest creation has altogether expanded lately around the world, as it permits a more proficient utilization of water and composts, just as a superior control of atmosphere and vermin factors. Moreover, aqua-farming creation builds crop quality and efficiency, which brings about higher intensity and financial earnings. Among factors influencing aqua-farming creation frameworks, the supplement arrangement is viewed as quite possibly the most significant deciding elements of harvest yield and quality. This section expects to disclose angles identified with plant nourishment and its impacts on creation of aquaculture crops, considering fundamental viewpoints, for example, supplement arrangements and their improvement as the years progressed; parts of supplement arrangements (large scale and micronutrients), considering models of nutrimental centrality in higher plants and their characterization, just as a concise portrayal of their capacities in plants; we characterize the idea of beneficial component and its grouping, and refer to certain instances of their expansion to supplement arrangements. The idea of pH of the supplement arrangement is additionally characterized, just as its impact on nutrimental accessibility; osmotic capability of the supplement arrangement and its relationship with electric conductivity are talked about, other than their pre-owned units and their equivalences, and the impact of the two elements on the supplement take-up in plants (2012).

According to Gabriel et al., (2018). The development of new technology for food production is essential to sustain man’s needs for survival. The use of farmlands for food production and industrial purposes goes beyond the carrying capacity of the environment. The study determined the applicability of Vertical Farming using Hydroponic Technology to onion production in Nueva Ecija, Philippines. The country is known as the onion capital of Southeast Asia. The study measured the technology’s sustainability and acceptability to onion farmers. By using experimental method, interview, and Focused Group Discussions (FGD), the study established its viability. Three phases of field experiments were conducted in August 2016, May 2017 and July 2017 using the Vertical Farming and Hydroponics Technology and Single Factor Analysis of Variance. The results showed that there is significant difference in the growth of onion bulb per week and the suitability and comparability of the technology to conventional farming. The study concluded that the VFH technology is acceptable to most onion farmers except the aspect of the cost of initial investment which requires government subsidy for the ordinary onion grower to avail of this new and sustainable technology in onion production.

There has been huge exploration done on aquaculture as a horticultural creation procedure for vegetable creation. The University of the Philippines in Los Baños has accomplished momentous work in aqua-farming, and there are various Filipino analysts that are pioneers in the field. What has not been done, and where this examination is intensely important, is in the use of tank-farming to metropolitan housetops and the utilization of a serious plan of action connecting nearby creation to on location usage, lessening the expenses of the food store network. This model gives a reasonable answer for horticulture as well as gives a financially feasible plan of action. The examination falls under the classification of manageable agribusiness. The worldwide populace is assessed to contact seven billion individuals in 2012. How might every one of these individuals be taken care of while ensuring and protecting the worldwide environment simultaneously? Food creation devours a lot of normal assets, that is, water, land, and minerals. Additionally, mechanical farming practices dependent on synthetic pesticides and herbicides, despite the fact that it builds yield, have caused general wellbeing dangers and environment contamination (Calleja et al., 2016).

According to Ordoñez (2017), Hydroponic methods water (hydro) should work (ponics) for you. Tank-farming is the technique for developing plants in supplement advanced water rather than soil. In soil, natural disintegration separates natural issue into the essential supplement salts that plants feed on. Water breaks down these salts and permits take-up by the roots." The upside of aquaculture is that the water utilized contains just the most fitting essential supplement salts for a given plant. This ideal mix is seldom found in soil.

Additionally, creation is contained in a little thought zone. The water is utilized again and again, with a new blend of supplement salts for each creation cycle. Climate change has made the growing of food risky. This is because you cannot predict the timing or severity of its occurrence. Hydroponics is the answer to this. When there is too much water because of a sudden storm or too little water because of drought, hydroponics conducted in the safety of a greenhouse can produce the highest quality product.
