Summary: This study investigates the influence of cropping intensity and diversity on labor requirements and productivity. The results show that as cropping intensity increases, labor demand also increases. However, there are only small differences in labor demands between systems with different crop diversity. Labor demand is highly seasonal, with peaks during intensive operations like sowing and harvesting. The study also highlights that the most profitable systems may not be the most efficient in terms of labor productivity.

Summary: In the Level Barind Tract of Bangladesh, the replacement of traditional Transplanted Aman and Boro rice cultivation with high-yielding potato, cucumber, and T. Aus rice has significantly improved system productivity, profitability, and sustainability, leading to increased food security and reduced environmental impact.

Summary: The study found that the maize + cowpea(f)-gobhi sarson-summer moong crop sequence was the most energy efficient, while the maize-potato-mentha + onion crop sequence had the lowest energy efficiency. Energy productivity increased with higher irrigation water application, suggesting the adoption of alternative cropping sequences to reduce irrigation water requirements.

Summary: The study found that foreign investment has a positive impact on the labor productivity of domestic firms in the middle and high quantiles in the Vietnamese manufacturing industry. However, there is not significant evidence to support a positive relationship between foreign investment in downstream sectors and domestic firm labor productivity in upstream sectors. There are indications of a positive relationship between foreign suppliers in upstream sectors and labor productivity of domestic buyers in downstream sectors, especially at the low and middle quantiles.

Summary: This article investigates the relationship between intellectual capital and profitability, market value, productivity, and return on equity of firms registered on Casablanca Stock Exchange. The findings suggest that variables like HCE, company size, and company leverage accurately predict profitability, with HCE having the greatest impact. Additionally, CEE is found to be an important indicator of both ROE and productivity, while company size is the only determinant of market value. Overall, the ICT firms have higher intellectual capital efficiency than SCE firms.

Summary: Skills are strong predictors of earnings, but the influence of labor market size on skill return remains unclear. Using data from a unique survey recording the skill requirements of Hungarian firms, this study finds that social skills have higher returns in large urban labor markets, while cognitive skills do not show this pattern. In addition, the return to manual skills slightly decreases with labor market size. However, the returns to skills seem to vary considerably across worker groups.

Summary: Fertilization significantly influences the diversity and composition of sorghum-associated microbial communities, particularly in rhizosphere and bulk soil microbiomes. Specific genera of bacteria and fungi are important predictors of sorghum yield and protein content. Fertilization has a positive indirect effect on sorghum yield and protein content through influencing microbial diversity in soil microbiota.

Summary: This study explores the role of technology spillover in the negative relationship between corporate investment and subsequent stock returns. It finds a strong negative relationship between corporate investment and stock returns when there is a high level of technology spillover. The study also examines the role of technology spillover in the positive relationship between corporate profitability and subsequent stock returns.

Summary: The study reveals that family firms are more efficient in labor investment compared to non-family firms, as they avoid issues of over-firing and underinvestment in employment. Family firms make more efficient labor-related decisions when they have greater external financing, demonstrating the importance of a long-term perspective in maintaining optimal labor levels.

Summary: A combination of in-situ climatic variables and remote sensing data is used to assess the dryness of planetary ecosystems. The drought index (DI) is compared with other indices for different land cover classes in China, showing comparable performance in capturing the impact of drought on vegetation photosynthesis. DI is also positively correlated with crop yield.

Summary: The study evaluated the yield and profitability of different cropping systems, finding that the winter wheat + relay intercrop red clover system had the highest system yield and was most profitable. Producers can increase profitability by diversifying their cropping systems with this approach.

Summary: Carbohydrate metabolism plays a crucial role in developmental growth and yield-related traits. This study systematically dissected genes in the whole carbohydrate metabolism pathways using meta-transcriptome data, identifying tissue-preferred carbohydrate genes for future research. Functional analysis revealed source activity and eating quality as the most common functions of characterized carbohydrate genes, providing new insights for improving rice yield.

Summary: The research on different nutrient management methods in wheat cultivation found that wheat growth and yield were improved by incorporating farmyard manure and bio-stimulants, and soil health was promoted. Application of farmyard manure, NPK bio-fertilizer+urea, and bio-stimulant+NPK sprays synergistically increased grain yields significantly.

Summary: Return migrants are often considered to suffer from lower earnings, but family needs can influence their migration decision and work-time allocation. This study shows that the losses in earnings for female young adults returning home are overestimated when family characteristics are not taken into account. However, the negative self-selection of male return migrants remains even after controlling for family characteristics.

Summary: The optimal allocation of agricultural water and land resources is crucial for farmers' economic benefits, carbon sequestration, and water resource conservation. This study developed a novel water-carbon-economy coupling model and applied it to a real farm, demonstrating its effectiveness in achieving the optimal allocation of water and land resources. The model balances economic, environmental, and social benefits.
