spreading faba bean (vicia faba) cultivation can enhance the sustainability of cropping systems and have other important benefits. however, there is little information on the various aspects of production management for this crop. then, this experiment was carried out to study the response of some agronomic characteristics of faba bean cv barakat to inter- (15, 30, 45 and 60 cm) and intra-row (...

in order to study the effect of row spacing and plant density on quantity and quality yield of soybean in weed competitive condition, a field experiment was carried out at research farm of yasuj agricultural college in summer of 2011. experiment arrangement was split factorial base on randomized complete block design with three replication. the main factor included weed ( in two levels of contr...

Little is known about optimising the productivity of intercropping through exploiting differences between genotypes. Our study evaluates performance three winter wheat cultivars and eight faba bean genotypes (experimental inbred lines) sown as replacement row intercrops with sole cropping comparisons. Detailed agronomic, physiological soil-based measurements were taken over consecutive autumn-s...

The single row routing problem is considered. It is shown that the use of backward moves can reduce street congestion when four or more tracks per street are available. We obtain an O((2k)!k*n*log k) algorithm to determine whether or not n nodes can be wired when only k tracks per street are available. An efficient algorithm is obtained for the case when wires are not permitted to cross streets...

High yielding superior groundnut cultivar development is the main objective of breeding programs. A four-year study was conducted in Eastern Mediterranean Agricultural Research Institute 2001, 2002, 2003 and 2004 growing seasons to evaluate for yield quality characteristics 80 varieties. The field experiments were laid out a 3 replicated randomized complete block design. In research, row spacin...

In this article we review the 2011 International Planning Competition. We give an overview of the history of the competition, discussing how it has developed since its first edition in 1998. The 2011 competition was run in three main separate tracks: the Deterministic (Classical) Track; the Learning Track; and the Uncertainty Track. Each track proposed its own distinct set of new challenges and...

With recent, dramatic changes in Arctic sea ice and the Antarctic ice sheets, the importance of monitoring the climate of the polar regions has never been greater. While many individual global satellite products exist, the AVHRR Polar Pathfinder products provide a comprehensive set of variables that can be used to study trends and interactions within the Arctic and Antarctic climate systems. Th...
