Fertigação em mudas de citros utilizando-se mangueiras e microtubos sob regime de escoamento turbulento Fertigation on citrus seedlings using hoses and microtubes under turbulent flow regime

Revista Brasileira de Engenharia Agrícola e Ambiental, 2011
A irrigação localizada utilizando-se microtubo como emissor operando em regime de escoamento turbulento, pode ser uma alternativa viável, tanto técnica como economicamente para a produção de mudas de citros.

Seeds of change: The impact of Ethiopia's direct seed marketing approach on smallholders' seed purchases and productivity

American Journal of Agricultural Economics, EarlyView.
Abstract While multiple factors explain low adoption rates of improved varieties by small‐scale farmers in sub‐Saharan Africa, a key supply‐side constraint is the limited availability of seed embodying new traits in the volume, quality, price, and timeliness required by farmers. This constraint is partly attributable to classical failures in the market

A Shift From Environment‐ to Plant‐Based Irrigation: Wearable Sensors Enabling Next‐Generation Feedback Control

Food and Energy Security
Global water scarcity demands a shift in environment‐based agricultural irrigation toward plant‐based irrigation approaches. Traditional irrigation methods, which rely on fixed schedules or environmental proxies, are inherently inefficient and often lead

Redistributive land reforms, agricultural productivity, and structural change: New cross‐national evidence

American Journal of Agricultural Economics, EarlyView.
Abstract Large‐scale land reforms constitute a substantial redistribution of wealth and reallocation of agricultural land, which is a major form of asset and production input in developing countries. While land redistribution (from the rich to the poor) remains a highly controversial issue, extensive evidence on its effect is limited.

Climate change and perennial crop production: Evidence of yield impact and adaptation in California

American Journal of Agricultural Economics, EarlyView.
Abstract Perennial crops are economically important. They contribute to food security, providing essential nutrients that are often lacking in annual crops, and provide additional environmental benefits compared with annual crops. Despite their importance, empirical research on the impacts of climate change and adaptation on perennial crops remains ...

Drip Irrigation Coupled with Wide-Row Precision Seeding Enhances Winter Wheat Yield and Water Use Efficiency by Optimizing Canopy Structure and Photosynthetic Performance

Agronomy
To address the bottlenecks of low water and fertilizer utilization efficiency and limited yield potential inherent in Henan Province’s traditional winter wheat cultivation model of “furrow irrigation + conventional row seeding”, this study delved into ...

The role of venture‐financed startups in innovation for US agriculture

American Journal of Agricultural Economics, EarlyView.
Abstract To evaluate the role played by startup companies in the innovation ecosystem of US agriculture, we compile a unique dataset of 6024 new entrants founded 1987–2019 that details their financing lifecycles, annual economic performance, and patenting activities.

Exposure to heat waves and drought improves subsequent leaf heat tolerance for five oak species in southern California

American Journal of Botany, EarlyView.
Abstract Premise Given the threats of climate change, we investigated the impact of high temperatures separately and in combination with reduced soil water on leaf heat tolerance for five oaks (Fagaceae) with overlapping ranges in southern California, USA: Quercus agrifolia and Q. chrysolepis (evergreen species), Q. douglasii and Q.
