Large-scale community-based content management requires “good” domain abstractions and, therefore, a serious investment into application ontology. In an interdisciplinary project with our Art History colleagues who are working in the subject domain of “Political Iconography” we are gaining substantial insight into their subject-oriented working (SOWing) modes and into initial requirements for a...

In northern Europe, replacing winter barley with winter wheat as the preceding crop for winter oilseed rape (Brassica napus L.; WOSR) often results in a delayed WOSR sowing and poor autumn growth. Based on data from a field experiment running in 2009/2010, 2010/2011, and 2012/2013, this study aims (i) to investigate how a delayed sowing method affects seed yield, N offtake with the seeds, and a...

The unpredictability and large fluctuation of the climatic conditions in rainfed regions do affect spring wheat yield and grain quality. These variations offer the opportunity for the production of better quality wheat. The effect of variable years, locations and sowing managements on wheat grain yield and quality was studied through field experiments using three genotypes, three locations for ...

The current real-time detection of sowing depth has the problems low accuracy and poor reliability. After analyzing movement mechanism monomer parallel four-bar linkage, an improved adaptive Kalman filtering method for is proposed. uses two MPU6050 attitude sensors. difference between rotation angle linkage used as relative to monomer. characteristics up–down translation, changes can be obtaine...

Annually, 200 ha of Agh Ghala rangelands in Golestan, Iran are under Alkaligrass Puccinella distans's cultivation but the failure in the identification of appropriate sites for seed sowing may result in high costs of cultivation. The current study aims to reduce such costs through the examination of apt sites to grow P. distans in northern rangelands of Agh Ghala Golestan, Iran. Because of the ...

Abstract The authors have designed a seed pelleter and combined precision sowing rig, which are the backbone of technology pre-sowing treatment sowing. method is based on operation continuous pelleter, where protective nutritious coating formed around seeds while they move along spiral trajectory. next component rig that performs several technological operations in one pass: laying drip tape fo...

Germinant sowing is operational for tree nurseries in South Africa. The technique reduces seed costs for eucalypts and pines. Filled cell percentage is usually near 98%. Seed efficiency at many North American container nurseries can be improved by adopting either germinant sowing or single sowing technology. Tree Planters' Notes xx(x):xx; 199x. INTRODUCTION Managers at most container nurseries ...
