This paper presents the integration of an UAV for the autonomous monitoring of rice crops. The system integrates image processing and machine learning algorithms to analyze multispectral aerial imagery. Our approach calculates 8 vegetation indices from the images at each stage of rice growth: veg...

Aerial Monitoring of Rice Crop Variables using an UAV Robotic System
Irrigated rice cultivation is a major source of greenhouse gas (GHG) emissions from agriculture. Methane (CH4) and nitrous oxide (N2O) are emitted not only throughout the growing season but also in the fallow period between crops. A study was conducted for two transition periods between rice crop...

Embracing whole plant optimization of rice and wheat to meet the growing demand for food and feed
Rice is an important staple crop whose production is limited by array of insect pests and diseases. African rice gall midge (AfRGM) Orseolia oryzivora Harris & Gagné (Diptera: Cecidomyiidae) is a major insect pest of lowland rice ecology in Africa. Heavy yield losses have been recorded in many fa...

Public policy-makers and scientists have expressed renewed interest in the prospects for on-farm conservation of crop genetic resources in recent years, but understanding of the economic incentives for and mechanisms through which programmes might best be implemented remains sketchy. Working thro...

Purpose _ We examine the joint demand for components of a household’s diet diversity and its relationship with household and regional characteristics that embody diverse food access and utilization constraints within the framework of the dietary patterns of rice producers in Peru. Methodology/app...

Upland rice breeding led to increased drought sensitivity in Brazil
Rice is the most important food crop in the developing world. For rice production systems to address the challenges of increasing demand and climate change, potential and on-farm yield increases must be increased. Breeding is one of the main strategies toward such aim. Here, we hypothesise that c...

Labor‐saving and income‐increasing technologies may affect women farmers differently from men. However, very few studies explicitly account for women's preferences for new technologies. We carried out a discrete choice experiment with 337 female and 329 male farmers in Maharashtra, India, to meas...
