The current study was designed to investigate the best sowing method that encourages dry matter accumulation increase dryland wheat yield, grain quality, and protein content. Three different seeding methods were applied: (I) wide-space (WSS), (II) furrow sowing, (III) drill sowing. Two nitrogen levels, namely low (N1) high (N2), also applied, pure 150 kg ha−1 210 ha−1, respectively. Wide-space ...

The test platform of wheat precision seeding based on image processing techniques is designed to develop the wheat precision seed metering device with high efficiency and precision. Using image processing techniques, this platform gathers images of seeds(wheat) on the conveyer belt which are falling from seed metering device. Then these data are processed and analyzed to calculate the qualified...

This study was conducted to determine whether selecting an optimum sowing date couldimprove yield. The experiment consisted of sowing a film-covered, drip-irrigated cotton field onfour sowing dates from April to May in 2011-2012 at the Agrometeorological ExperimentalStation of Wulanwusu, which was in an arid region of north-western China. Late sowing datesproduced less yield and water-use effic...

A knowledge model with temporal and spatial characteristics for the quantitative design of a cultural pattern in wheat production, using systems analysis and dynamic modeling techniques, was developed for wheat management, as a decision-making tool in digital farming. The fundamental relationships and algorithms of wheat growth indices and management criteria to cultivars, ecological environmen...

Cliff sides are extreme habitats, often sheltering a rich and unique flora. One example is the dioecious herb Borderea chouardii (Dioscoreaceae), which is a Tertiary, tropical relict, occurring only on two adjacent vertical cliffs in the world. We studied its reproductive biology, which in some aspects is extreme, especially the unusual double mutualistic role of ants as both pollinators and di...
