Organic Farming System

Abstrak               Tantangan pertanian ke depan adalah peningkatan produksi pertanian, kelestarian lingkungan dan kesehatan masyarakat sebagai akibat meningkatnya jumlah penduduk dan kesadaran masyarakat akan pengaruh negatif yang ditimbulkan oleh penggunaan pupuk anorganik dan pestisida sintetik/kimia (anorganik).  Sistem pertanian organik merupakan salah satu solusi yang diajukan untuk diterapkan pada sistem pertanian di masa yang akan datang.  Sistem pertanian organik adalah sistem budidaya pertanian yang mengandalkan bahan-bahan alami tanpa menggunakan bahan kimia/sintesis (anorganik).  Pemanfaatan pupuk organik dan pestisida nabati dalam usaha pertanian akan mengurangi resiko pencemaran lingkungan, meningkatkan efisiensi pemupukan, serta menekan pengaruh negatif dari penggunaan pupuk anorganik dan pestisida sintesik/kimia (anorganik).  Prinsip dalam sistem pertanian organik adalah adanya keseimbangan siklus hara dan kesuburan tanah serta pengendalian hama dan penyakit secara terpadu.  Untuk meningkatkan kesuburan tanah dan memenuhi kebutuhan pupuk organik di dalam menjaga keseimbangan siklus hara, serta mengurangi penggunaan pestisida nabati, peran legum seperti bengkuang (Pachyrrhizuz erosus L.) perlu dikaji lebih mendalam. Tanaman bengkuang sangat potensial dalam mendukung diterapkannya sistem pertanian organik karena; biomassa yang banyak dan mengandung nitrogen yang tinggi (3.42% - 3.51%), kemampuan hidup yang sangat luas di berbagai kondisi lahan karena bersimbiosis dengan bakteri Rhizobium dan Bradyrhizobium dalam menambat nitrogen (N2) udara dan bersimbiosis dengan cendawan mikoriza (AMF) yang dapat membantu penyerapan unsur hara terutama fosfor.  Selain itu, kecuali umbi, bagian tanaman lainnya terutama pada biji bengkuang mengandung metabolit sekunder seperti rotenon yang bersifat insektisida.  Dengan demikian maka bengkuang ini dapat dimanfaatkan sebagai bahan pupuk organik dan sebagai insektisida nabati dalam mendukung sistem pertanian organik. Kata Kunci: bengkuang(Pachyrrhizuz erosus L.), legum, rotenon, sistem pertanian organik Abstract                The challenge of agriculture in the future is to increase agricultural production, environmental sustainability and public health as a result of increasing population and public awareness of the negative effects caused by the use of inorganic fertilizers and chemical/ synthetic pesticides. Organic farming system is one of the solutions proposed to be applied to agricultural systems in the future. Organic farming system is an agricultural cultivation system that relies on natural materials without using synthetic/chemicals (inorganic). Utilization of organic fertilizers and pesticides in agricultural businesses will reduce the risk of environmental pollution, improve fertilization efficiency, and reduce the negative effects of the use of inorganic fertilizers and chemical/synthetic pesticides. The principle in organic farming systems is the balance of nutrient cycling and soil fertility and integrated pest and disease control. To improve soil fertility and meet the needs of organic fertilizer in maintaining the balance of nutrient cycles, and reduce the use of synthetic chemical pesticides, the role of legumes such as yam bean (Pachyrrhizuz erosus L.) needs to be studied more deeply. Yam bean plants are very potential in supporting the implementation of organic farming systems because; a lot of high and nitrogen containing biomass (3.42% - 3.51%), a very broad life ability in various land conditions because it is symbiotic with Rhizobium and Bradyrhizobium bacteria in fixing nitrogen (N2) air and symbiosis with mycorrhizal fungi (AMF) which can help absorption of nutrients, especially phosphorus. Especially in jicama seeds contain secondary metabolites such as rotenone which are insecticides. Thus, this yam bean can be used as an organic fertilizer and as a organic/vegetable insecticide in supporting organic farming systems. Keywords: Yam bean (Pachyrrhizuz erosus L.), legumes, rotenon, organic farming systems

Organic Farming System

Excessive use of inorganic chemicals results in adverse impacts on land and plants. In the midst of the community, there is anxiety about the high content of pesticide residues in agricultural products. There is a need to develop alternative farming systems that are able to produce quantities and quality of healthy products in a sustainable manner. One agricultural system that supports the concept is the organic farming system. The basic principles of organic farming are: (1) Keeping the ecosystem healthy, (2) Applying the principle of efficiency to the cultivation system, (3) Conducting production activities with the concept of sustainable agriculture, (4) Producing pesticide-free products, and (6) Maintaining environmental sustainability. Food Crop Production Study Program Lampung State Polytechnic makes Organic Agriculture as one of the leading competencies for its graduates. The establishment of the Organic Agriculture Business Unit on campus will increase student competencies, foster entrepreneurship, be a place for competency internships, and as an independent source of income.

A study was carried out to know the response of organic, integrated and conventional farming systems on the diversity of soil meso and macro arthropod populations in the cotton inter cropped with groundnut and pigeonpea at MARS, UAS, Dharwad during kharif -2015-16. The organic farming system has recorded highest meso and macro arthropod population of 21.35 per 100 g of soil and 42.00 per pitfall trap respectively. Cotton intercropped with groundnut has recorded higher population of meso and macro arthropods (15.50 /100 g of soil and 41.26/ pitfall trap, respectively). The seasonal abundance of soil arthropods was high in October (25.89/100g of soil) and least in December (5.78/ 100g of soil) months. The diversity of soil arthropod populations assessed on the Shannon’s index of below ground arthropod populations recorded was highest in organic farming (0.61) and least in conventional farming (0.51) system. Hence, the organic farming system increases abundance and diversity of soil organisms and soil fertility, and it adds large amounts of organic residue inputs, which in turn increases the biological activity in soil.

Organic farming standards do not allow addition of water-soluble fertilisers and therefore it is likely that growth of organically grown crops will be limited by nutrient availability. However, in marginal rainfall conditions, when growth in conventional systems is limited by water availability, yields of organically grown crops could be comparable with those conventionally grown. Similarly, micronutrient-efficient plant varieties could be expected to perform comparatively better under organic farming conditions than they do in conventional systems, when compared with micronutrient-inefficient varieties.In this study, biomass and grain production of wheat from certified organic farming systems were compared with neighbouring conventional farming systems in 'across the fence' field trials in 1 moderate and 2 marginal rainfall areas of South Australia. Wheat varieties compared included 2 old wheat varieties developed under relatively low-input conditions (Baroota Wonder and Dirk-48) and varieties shown to be micronutrient-efficient (Janz and Trident) and inefficient (Yallaroi).The organic farming systems produced significantly less biomass than the conventional farming systems at late tillering in both the moderate and marginal rainfall areas. Grain yield was variable, but significantly lower in the organic farming system for 11 of the 14 comparisons. None of the varieties showed an adaptive advantage for 1 farming system over the other. The relative yield of the organic system, compared with the conventional system, was not associated with rainfall.

A weed is a plant that is considered to be nuisance and unwanted plant in human-controlled settings,especially farm field and garden. The weed that grow in surrounding of crop could decrease yield due to competitionoccur between weed and crop on nutrition, sunlight and water. Organic farming system which has been developednowadays is an environmental friendly organic farming system. The objective of this research is to determine weedcompetition on carrot using several kinds of organic fertilizer. Six treatments were used in this research, i.e., greenmanure, combination of green manure and EM, EM alone and control (without manure and EM). The weed wasgrowth together with carrot for 3 months. The parameters are wet weight and dry weight of carrot per meter square.The results show that manuring could increase weed competition which in turn wet weight and dry weight of carrotare decreasing. The highest competition between carrot and weed occurred in the treatment of combination betweenorganic manure which combines with EM. The added EM on organic manure could increase weed competition oncarrot.
