Sustainable agriculture bases on certain ecological principles in both of crop production and livestocks. Legume-cereal intercropping in sustainable agricultural cropping system is the most applied in the intercropping systems in the World. Legume-cereal intercropping have many benefits such soil conservation, weed control, animal feed and effective land use, greater yield and quality in low-input agricultural system. Land use efficiently is available to evaluate the advantages of intercrop in sustainable agriculture to meet food demand due to increase in population. Amount of N2 fixed by intercropped legume is less compared to mono crop legume due to competition with cereal. However, proportion of total N derived from fixation (Ndfa %) in legume intercropped with cereal was greater than mono crop legume. N-transfer from the legume to neighbouring plant may be possible, but it can be affected by a lot of factors. The principal aim of present study is to define advantages of cereal-grain legume intercrops in sustainable agriculture.

Nowadays, immediate environmental friendly solutions such as the use of biopesticides and other methods to control and manage pests are well needed. They are imperative due to the continuous accumulation of toxic residues from synthetic insecticides into the environment, the contamination of global agro-ecosystem and resistance of certain insects and pathogens. The global renewed interest of botanical pesticides does not leave aside Turkey. Thus, many environmental reports pointed out contaminations in different regions of Turkey by chemical pesticide residues, like lambda-cyhalothrin in some conventional grapes farming in the Aegean region. The use of botanical pesticides like Pyrethrin extracted from Pyrethrum’s flowers (Chrysanthemum cinerariifolium) is part of sustainable agriculture goals to reduce the incidence of pests and diseases without any alteration to the natural balance. The purpose of this review is to analyse and identify the possibilities of Pyrethrum production in Turkey. Various research works around the world were compiled and some key informants were correlated to existing researches in Turkey. Subsequently, it was found that the Black-Sea region of Turkey has great potential in the growing and industrial production of Pyrethrum by its weather patterns (temperatures, pluviometry and humidity) and soil characteristics. The region has a similar climate with the East-African high-lands well-known for Pyrethrum production. Thus, the country has shown great technological advances and the capacity to produce vegetative and disease-free clones for other ornamental plants by using tissue culture techniques. Therefore, the multiplication of high-quality vegetative clones of Chrysanthemum cinerariifolium and their maintenance can sustain commercial and long term production of Pyrethrum in Turkey.

Compost is usually made of biodegradable wastes. Today, compost, bio-agent bacteria and mycorrhizae are used as the key components of sustainable agriculture. This study was conducted to determine the effects of compost treatments alone and combined with bacteria, mycorrhiza and commercial fertilizers on growth, flower and bulb quality parameters of the ‘Jan van Nes’ tulip cultivar. Compost was made of grape pomace and set at different EC levels. Three different compost ratios (0%, 20% and 40%), three different EC levels (0.75, 1.10, and 1.45 dS/m) and combinations with or without bacteria and mycorrhizae were experimented. Flower stalk length, perianth length and vase life were identified as the most striking parameters for growth and flowering of tulip plants. The best outcomes in terms of flower stem length (34.20 cm), perianth length (44.85 mm) and vase life (7.00 days) were obtained from 0% compost treatments. Increasing compost ratios had adverse effects on plant growth and bacteria and mycorrhizae treatments alone did not provide any significant effects. However, combining with different compost ratios increased the effectiveness of bacteria and mycorrhiza. EC of 0.75 yielded better results than the other EC levels.

The aim of this study is to determine the indicators used to determine the sustainability levels of nut farms and to establish a set of indicators that can be used to measure the level of sustainability of pistachio farms, based on the literature review. As a result of the literature review, among the indicators commonly used to measure agricultural sustainability, a total of thirty sub-criteria were identified, including fifteen sub-criteria for the economic aspect (farm size, yield, etc.), six sub-criteria for the environmental aspect (pesticide, fertilizer, water, energy usage, etc.) and nine sub-criteria for the social aspect (farmer’s age, education, etc.) which can be used in evaluating the sustainability of pistachio cultivation. According to this study's findings, although the theoretical principles, dimensions, and goals of agricultural sustainability are globally adaptable, the applicability of the indicators may vary between regions and countries due to geographic, climatic, and socio-cultural differences. Therefore, the sustainability assessment process requires special attention. Sufficient knowledge and expertise are required in setting goals, selecting indicators, and verifying indicators.

Innovative farming techniques are essential for food security and sustainable farming practices. Innovative agricultural approaches utilize modern technologies and the latest inventions, as well as traditional agricultural practices. The main purpose of this study is to address the relationship between sustainable agriculture and bioeconomy and to examine innovative approaches that are expected to have a significant impact on the agricultural sector in the near future. The study was carried out in compilation format. Bioeconomy is an economic model or methodology based on the economic evaluation of biological resources and processes. Abiotic resources such as microbes, vegetation, animals, and biodiversity are all included in this strategy. On the other hand, sustainable agriculture, which aims to protect natural resources and take into account ecosystem benefits while maintaining food production, is an agricultural paradigm. The primary goals of bioeconomy and sustainable agriculture are economic evaluation, efficient use of natural resources and reduction of environmental impacts. Considered from these perspectives, it can be said that both concepts have common purposes and are closely related. It is possible to say that with the increasing use of sustainable agricultural methods and bioeconomy, the agricultural sector can move towards a more environmentally friendly, efficiently managed and sustainable structure in the future.

Agroforestry is a conventional method of land use that could help to address agricultural environmental issues. In order to take advantage of the ensuing ecological and economic interactions, agroforestry is the technique of consciously integrating woody vegetation (trees or shrubs) with crop and/or animal systems. According to recent studies, the global agri-food industry may reach more sustainable methods of producing food and fiber by adopting agroforestry techniques and principles more widely. This would benefit farmers economically and would benefit society as a whole in terms of the environment. Agroforestry promotes eco-intensification based on resource efficiency and offers a wide range of provisioning, regulating, cultural, supporting ecosystem services, and environmental advantages. In this review, we discussed agroforestry with its advantages and developments.
