Ear density is one of the most important agronomical yield components in wheat. counting time-consuming and tedious as it often conducted manually field conditions. Moreover, different sampling techniques are used resulting a lack standard protocol, which may eventually affect inter-comparability results. Thermal sensors capture crop canopy features with more contrast than RGB for image segmentation classification tasks. An automatic thermal ear system proposed to count number ears using...

In spite of the benefits heterosis in maize breeding, little is known about physiological mechanisms this phenomenon and its genetic control under different water regimes. This study aimed to understand effects on plant growth, photosynthetic transpiration traits, root traits four inbred popcorn lines their hybrids, including reciprocal combinations. Plants were grown lysimeters, inside a rain shelter, two conditions (water stress – WS; well-watered WW) until anthesis. Plant growth included...

The second United Nations Sustainable Development Goal (SDG2), zero hunger, aims to improve the productivity, food security, nutrition, and sustainability of small-scale farmers. fall armyworm (FAW, Spodoptera frugiperda) has been devasting smallholder farmer security since it spread sub-Saharan Africa in 2016, who have suffered massive crop losses, particularly maize, an important staple for basic sustenance. Since FAW mainly devours green leaf biomass during maize vegetative growth stage,...

The productivity of wheat in the Mediterranean region is under threat due to climate-change-related environmental factors, including fungal diseases that can negatively impact yield and quality. Wheat phenotyping tools utilizing affordable, high-throughput plant (HTPP) techniques, such as aerial ground RGB images quick canopy leaf sensors, aid assessing crop status selecting tolerant varieties. This study focused on region, considering need for a precise selection research examined use...

Ear density, or the number of ears per square meter (ears/m2), is a central focus in many cereal crop breeding programs, such as wheat and barley, representing an important agronomic yield component for estimating grain yield. Therefore, quick, efficient, standardized technique assessing ear density would aid improving agricultural management, providing improvements preharvest predictions, could even be used tool when it has been defined trait importance. Not only are current techniques...

Fall armyworm (FAW) is a polyphagus pest with preference for young maize leaves that relocates to the cob during development and can devastate yields. Time series anomaly change detection first derivative growth pattern analyses were conducted under hypothesis that, if unimpeded occurring vegetativegrowth stage, FAW presence will result in reduction of LAI or total green biomass (NDVI) crop. We have observations NDVI/LAI at three different scales from continental field scales., (i)...

Proximal remote sensing devices are novel tools that enable the study of plant health status through measurement specific characteristics, including color or spectrum light reflected transmitted by leaves canopy. The aim this is to compare RGB and multispectral data collected during five years (2016–2020) four fruiting vegetables (melon, tomato, eggplant, peppers) with trial treatments non-grafted grafted onto resistant rootstocks cultivated in a Meloidogyne incognita (a root-knot nematode)...

The systematic use of plant protection products is now being called into question with the growing awareness risks they can represent for environment and human health. application precision agriculture technologies helps to improve agricultural production but also rationalize input costs ecological footprints.

Maize is the most commonly cultivated cereal in Africa terms of land area and production. Low yields this region are very often associated with issues related to low Nitrogen (N), such as soil fertility or fertilizer availability. Developing new maize varieties high reliable actual field conditions using traditional crop breeding techniques can be slow costly. Remote sensing has become an important tool modernization field-based High Throughput Plant Phenotyping (HTPP), providing faster...

The state-of-the-art on the use of commercially available consumer color digital cameras, which capture Red, Green and Blue light covering visible spectrum with broad spectral bands but at high spatial resolution accurate calibration has produced some interesting results in recent years, bringing back benefits "hyperspatial" imaging for estimating various plant physiological characteristics related to both biotic abiotic stressors. Here we will review RGB vegetation indexes that concept...

Currently, for Pinus pinea L., a valuable Mediterranean forest species in Catalonia, Spain, pinecone production is quantified visually before harvest with manual count of the number pinecones third year selection trees and then extrapolated to estimate productivity. To increase efficiency objectivity this process, we propose use remote sensing productivity every tree whole (complete coverage vs. subsampling). The unmanned aerial vehicle (UAV) flights high-spatial-resolution imaging sensors...
