This study examines the effectiveness of the bi-stabilization of clay soils using cane molasses and coconut fiber, focusing on improving the geotechnical and mechanical properties of clay. The performance of the two stabilizers, both individually and in combination for bistabilization, was assessed. The geotechnical properties were determined through sieve analysis, Proctor tests, and Atterberg limit methods, while the mechanical properties were measured using a hydraulic press. The results showed that cane molasses reduced plasticity, enhanced soil cohesion, and increased dry density with molasses content. The Atterberg limits (liquid limit, plastic limit, and consistency index) were maximized at a 4% molasses content, with respective increases of 9.28%, 44.80%, and 37.9% compared to clay without molasses (CB). Coconut fiber improved the flexural strength by 361.9% for CF1, whereas molasses improved the compressive strength by 12.24% compared to plain clay. Bi-stabilization allowed for a maximum improvement in flexural strength of 509.52% compared to CB, 49.42% compared to molasses-stabilized clay bricks (CSM), and 31.96% compared to clay composites with coconut fiber (CF). The compressive strength improved by 22.54% compared with CB, 9.21% compared with CSM8, and 14.94% compared with CF 1/2. In summary, bi-stabilization with sugarcane molasses and coconut fiber provided enhanced performance compared with their individual use.

Assessment of the effects of inoculation with entomopathogenic fungi on the vegetative growth and yield of Capsicum chinense under water stress conditions. Int. J. Agric. and gastronomic value. The cultivation of C. chinense is increasingly challenged by global warming and droughts, which impact both plant health and market stability. Climate change affects agriculture by altering temperature and precipitation patterns, leading to soil moisture loss, drought, phenological damage, and increased pest and disease incidence. The use of bioinoculants, including entomopathogenic fungi (EFs), may be a strategy to mitigate drought in C. chinense production. The aim of this study was to assess the impact of Beauveria brongniartii and Purpureocillium lilacinum inoculation on the vegetative growth and yield of C. chinense var. Chichen Itza under two water stress conditions. Experiments were conducted in a gothic greenhouse, and C. chinense seedlings were transplanted into growth bags [coconut fiber (70%) and dust (30%)] with controlled irrigation at 75% and 100% levels. The EFs were applied weekly for the first month (50 mL at 1x107 conidia mL-1). Agronomic parameters, including plant height, stem diameter, chlorophyll index, leaf area, fruit quality, and yield, were measured. The results indicated that both B. brongniartii and P. lilacinum significantly increased plant height and stem diameter in the early stages of growth under water stress conditions. B. brongniartii notably increased plant growth and maintained fruit yield even under reduced irrigation. However, no significant differences were observed in the chlorophyll index or overall fruit yield among the treatments. The results of this study suggest that B. brongniartii and P. lilacinum can improve C. chinense resilience to water stress, suggesting potential applications in sustainable agriculture amidst climate change.
