Organic Agriculture for Sustainable Food Systems: A Comprehensive Review of Benefits and Constraints 全文
2024
Shikha Sharma
The global population is increasing at a rapid pace, posing significant challenges to sustainable development and food security. This review paper examines the advantages and challenges of organic farming as a potential solution to address the pressing issues in modern agriculture and food production. Organic farming offers a range of benefits, including improved soil fertility, higher profitability, reduced external input usage, land reclamation, improved market access, and enhanced farmer capacity and self-reliance. Organic farming practices prioritize environmental sustainability by reducing chemical usage and reliance on biological methods of pest control, as well as enhancing biodiversity, which strengthens ecological balance and resilience against pests and diseases. However, organic farming also faces challenges that need to be addressed for its widespread adoption. These challenges include uncertainty surrounding legislative environments, psychological and sociological costs of conversion, financial risks during the transition period, securing marketing channels for organic produce, and diminishing profit margins. Efforts should be made to provide farmers with the necessary support, including technical assistance, subsidies, and access to markets, to overcome these challenges. Despite the challenges, the potential of organic farming in promoting sustainable agriculture and ensuring a secure food system cannot be overlooked. It offers a natural and environmentally friendly approach to food production, prioritizing the health of both humans and the ecosystem.

It is critical that Bangladesh faces water scarcity during the dry season, affecting lentil (Lens culinaris Medik.) yield and some yield components during seedling and flowering stages. Thus, a two-factorial pot experiments (The experiment comprises Factor A: three fertilization levels i.e. F1 = Control [inorganic], F2 = poultry litter-based compost [20 ton/ha], F3 = poultry litter-based compost [30 ton/ha]; Factor B: two irrigation levels such as W1 = 100% field capacity [FC] and W2 = 70% FC) were designed at Hajee Mohammad Danesh Science and Technology University, Dinajpur, from November 2018 to April 2019. And it was investigated how the poultry litter-based composts affected the morpho-physiology, yield and yield components of the lentil (BARI Masur-4) variety under different irrigation stress levels. Obtained results revealed that the tallest plant (30.7 cm at 75 DAS) and maximum branch number per plant (14.1 at 65 DAS), leaf chlorophyll a (0.30 mg/g), highest RLWC (70.28%), lowest proline content (1.57 µ moles g-1 FW), maximum number of pods per plant (39.4 at 75 DAS) and total grain yield (3.62 kg/m2) were recorded from compost F3 (poultry litter-based compost 30 tons/ha) with W1 (100% FC). Results also showed that the yield contributing attributes and yield of lentils were drastically reduced by water stress conditions with different rates of fertilization. In drought conditions (W2 = 70% FC), F3 (30 ton/ha poultry litter-based compost) fertilization produced the highest plant height (30.20 cm at 75 DAS), number of branches (11.5 at 65 DAS), stem dry weight (0.35 g), lowest proline (3.88 µ moles g-1 FW), highest pod number per plant (33.1), weight of 100-seed (2.36 g), total grain weight (2.77 kg/m2), harvest index (58.84%) compared to other fertilizations (F1 and F2). In summary, F3 (30 tons), a compost made from poultry litter, provides better soil conditions under drought conditions compared to F1 and F2 in the year of 2018-19 at the 0 and 20 tons/ha, respectively under the field conditions.

In this study, a new bitter chocolate with functional properties was produced by using different tempering temperatures with different ratios of wolfberry addition and physicochemical, antioxidant, textural and sensory properties of these chocolates were determined. It was observed that fruit ratios on bitter chocolate had a statistically significant (P<0.01) effect on DPPH, ABTS and hardness values, while there was no significant effect on total flavonoid amounts. It was determined that tempering temperature had a significant effect (P<0.01) on pH, reducing sugar, sucrose, total phenolic content (TPC), DPPH, ABTS, total flavonoids (TFC) and hardness values, while it had no significant effect on total dry matter and total sugar values. The rich total phenolic and antioxidant content of the added wolfberry fruit and its substitution for sugar improved the functional properties of the chocolate. As a result of the study, it was possible to introduce a value-added functional product with wolfberry additive to the market, thus pioneering the production of new products as well as the fresh use of the fruit.

Radish is a widely cultivated root crop susceptible to chemicals for its growth and development. The experiment was conducted to study the effect of different sources of organic fertilizers on growth and yield parameters in the Tokinashi variety of radish. The experiment was laid out using one factorial completely randomized block design with six treatments replicated four times. Vermicompost, goat manure, chemical fertilizers (NPK), poultry manure, farmyard manure and control were the applied treatments. Various growth and yield parameters of radish were measured and assessed at 15-day intervals. Various growth and yield parameters of radish were measured and assessed at 15-day intervals. Growth parameters were observed at 15, 30, 45, and 60 days after sowing. For yield parameters, destructive samples were taken and observed at 30 DAS and 45 DAS and harvested at 60 DAS. The assessments of plant growth and yield parameters showed that poultry manure (PM) treatments were superior. At the time of harvesting, the treatment comprising poultry manure had considerably greater plant height (30.55 cm), leaf length (29.44cm), leaf breadth (10.78cm), leaf number per plant (9.23), root diameter (10.33cm) and root length (20.16cm) with superior yield per ha (33.59 mt ha-1). Poultry manure significantly enhanced root yield and was positively correlated with all growth parameters. The highest benefit-cost (B: C) ratio was recorded in chemical fertilizer (3.99), which was statistically at par with poultry manure (3.81), suggesting that poultry manure might potentially replace chemical fertilizers for the Tokinashi variety of radish cultivation.

Yener Ataseven | Alper Demirdöğen | Mustafa Akyüz
As the organic agriculture sector grows, the need for standards, inspection, and certification systems to ensure trust in organic products increases. Organic agriculture revolves around standards that determine the practices that farmers must follow. These standards also create a plan for inspection and certification systems. These systems are the cornerstone of ensuring reliability in the organic agriculture sector. This study has been prepared to evaluate the inspection and certification systems within the framework of the sense of trust, which is a critical issue in the organic agriculture sector from farm to fork. The focus of this framework is to ensure that inspection and certification systems keep the principles of organic agriculture intact from farm to fork. This is because these systems are necessary to build trust, access markets, increase consumer confidence and support fair and ethical practices in the sector. However, it is suggested that areas such as facilitating accessible inspection and certification for small-scale farmers, improving consumer education and promoting cooperation for global standards should be studied as potential areas.

Çeltik, dünya nüfusunun yarısından fazlası için temel gıda kaynağı olan en önemli tahıl ürünlerinden biridir. Artan dünya nüfusunu sürdürülebilir bir şekilde besleyebilmek adına, tarımsal sulama yöntemlerinin geliştirilmesi ve su kaynaklarının verimli kullanımı üzerine çalışmaların yoğunlaşması gerekliliği giderek artmaktadır. Çeltik bitkisinin sulanan tarım alanlarının %34-43'ünü kullandığı tahmin edilmektedir. Küresel ölçekte su kaynakları hızla azalmaktadır ve çeltik üretiminde ihtiyaç duyulan toplam sulama suyu miktarı; kullanılan çeltik çeşidi, toprağın özellikleri ve ekim yöntemleri gibi çeşitli faktörlere göre farklılık göstermektedir. Bu çalışma, Tesadüf Blokları deneme desenine göre düzenlenmiştir. Çalışmada 2 çeltik çeşidi, 2 farklı sulama yöntemi (Geleneksel ve Alternatif tava ıslatma kurutma) ve 3 farklı ekim yöntemi (Sulu, Kuruya ve Fideleme) seçilmiş ve araştırma üç tekrarlamalı olmak üzere 36 lizimetrede yürütülmüştür. Araştırmada çeltikle ilgili bitki boyu, ana sap kalınlığı, salkım uzunluğu, metrekaredeki bitki sayısı, tane verimi, bin tane ağırlığı, kırıklı randıman ve kırıksız randıman gibi özellikler incelenmiştir. İncelenen parametreler üzerine araştırma konularının istatistiksel olarak etkisi olduğu tespit edilmiştir. Tane verimi açısından su uygulamasında geleneksel sulama ile alternatif ıslatma kurutma sulama yöntemi arasında %25 oranında tane verimin azaldığı tespit edilmiştir. Ekim yöntemleri açısından ise, sulu ekim, kuru ekim ve fideleme yöntemleri birbirini takip etmiştir. Yapılan araştırma sonucunda en yüksek tane veriminin suya ekim yönteminde ve geleneksel sulama ile elde edildiği tespit edilmiştir.
