in order to investigate the effect of seed rate on seed yield and yield components of three rapeseed varieties, a split- plot experiment was conducted in randomized complete block design with four replicates during 2008-2009 at baykola agricultural research station, neka, mazandaran province. in this experiment four seed rates (5, 7, 9 and 11 kg.ha-1) as main plots, three rapeseed cultivars (hy...

to achieve high seed yield of rapeseed varieties under semi cold rainfed conditions; twenty rapeseed varieties were compared in randomized complete block design with three replications in sararood agricultural research station for two years. combined analysis results indicated that there were significant differences at 5% probability level among years for number of days to start of flowering, n...

In this paper we describe a new branch and bound algorithm for solving 0-1 integer linear programs (ILP). The algorithm is specifically targeted at ILP instances that are highly constrained, i.e. instances for which the constraints are hard to satisfy. Our approach is based on recent algorithms for solving instances of Propositional Satisfiability (SAT) which are also highly constrained. In par...

A forest is an ensemble with decision trees as members. This paper proposes a novel strategy to pruning forest to enhance ensemble generalization ability and reduce ensemble size. Unlike conventional ensemble pruning approaches, the proposed method tries to evaluate the importance of branches of trees with respect to the whole ensemble using a novel proposed metric called importance gain. The i...

peach (prunus persica l. batsch.) is produced in most areas of iran, where flowering is hindered by temperature. using plant growth regulators to delay bloom is a suggestive measure to avoid frost damage. the objective of this study was to determine the effects of methyl jasmonate (mj) and salicylic acid (sa) on peach bloom delay and yield.  this study evaluated the applications of mj 0 (contro...

in order to study the effect of nitrogen rate and plant density on morphological traits and essential oil and fruit yield of coriander, a split-plot experiment was carried out in research field of islamic azad university, birjand branch, birjand, iran in 2010 based on a randomized complete block design with three replications. the main plots were nitrogen rates at four levels (0, 40, 80 and 120...
