Will Sustainable Food Sovereignty Research Be Sustainable in the Future?

引用

agricultural Sciences 2024年第1期15卷 165-186页

作者： Teck Choon Teo School of Business TMC Institute Tashkent Uzbekistan

The article proposes two agricultural paradigms to address global food production sustainability. First, precision agroecology may unite production-oriented and ecological agriculture, but it offers distinct solutions based on data, innovation, and decision-analysis technologies. The author demonstrates how precision technology and agroecological principles can transform agriculture by 1) minimizing inputs with optimization prescriptions, 2) replacing self-sustaining inputs with location variable rate technology, 3) integrating functional ecosystems into agroecosystems with exact preservation technology, 4) hooking up farmers and consumers via value-based food ecosystems, and 5) establishing equitable agroecology. Hence, precision agroecology provides a rare opportunity to integrate indigenous practices and contemporary technologies to revolutionize farming practices. Precision agroecology can tackle agriculture’s most serious sustainability issues in a world in flux.

Background Natural and synthetic plant growth regulators are essential for plant health,likewise these regulators also play a role in increasing organic production productivity and improving quality and yield *** the present study,we have evaluated the effects of foliar applied plant growth regulators,i.e.,moringa leaf extract(MLE)and mepiquat chloride(MC)alone and in combination MC and MLE on the conventional cotton cultivar(CIM 573)and transgenic one(CIM 598).The growth regulators were applied at the start of bloom,45 and 90 days after *** The application of MC and MLE at 90 days after blooming significantly improved the relative growth rate,net assimilation rate,the number of bolls per plant,and seed cotton ***,the combined application of MLE and MC at 90 days after blooming significantly boosted the nitrogen uptake in locules,as well as the phosphorus and potassium uptake in the leaves of both cotton *** application of MLE alone has considerably improved the nitrogen uptake in leaves,and phosphorus and potassium contents in locules of Bt and conventional cotton ***,Bt cotton treated with MLE at 90 days after blooming produced significantly higher ginning out turn and oil *** in combination(MLE+MC)at 90 days after blooming produced considerably higher micronaire value,fiber strength,and staple length in conventional *** The natural growth enhancer,MLE is a rich source of minerals and zeatin,improving the nutrient absorption and quality of cotton fiber in both conventional and Bt cotton cultivars.
