Ten self-fertile commercial sunßowers cultivars were evaluated for seed set with and without exposure to bees. In the Þrst planting, the number of foraging honey bees was smaller than in the second, and seed set for most cultivars did not differ between those bagged to exclude bees and ones that were open pollinated. In the second planting, however, a majority of cultivars had significantly gre...

To investigate the effect of depth of planting holes on yield and yield components of three cultivars of watermelon in dry land conditions, a two-year study (2006-2007) was carried out in Varamin Agricultural Research Center, using a split plot randomized complete blocks design in three replications. Three cultivars of watermelon (Mahbube, Charleston Gray and Sugar Baby) were assigned to main p...

Salinity and water stress reduces the ability of plant to take up water and decrease growth rate, photosynthesis rate (An) and stomatal conductance (gs) of plants. In this study, effects of deficit irrigation with different salinity levels and planting method (in-furrow and on-ridge) as strategies for coping with water and salinity stress on physiologic properties of rapeseed was investigat...

This study compares the accuracy of the short-term rainfall forecasts obtained with time-series analysis techniques, using past rainfall depths as the only input information. The techniques proposed here are linear stochastic auto-regressive movingaverage (ARMA) models, artificial neural networks (ANN) and the non-parametric nearest-neighbours method. The rainfall forecasts obtained using the c...

A critique is presented of the use of tree-based partitioning algorithms to formulate classification rules and identify subgroups from clinical and epidemiological data. It is argued that the methods have a number of limitations, despite their popularity and apparent closeness to clinical reasoning processes. The issue of redundancy in tree-derived decision rules is discussed. Simple rules may ...

In the present study, the effects of different levels of irrigation, organic mulch and planting method on the mungbean yield in Badjgah were investigated. The experimental plan in the first year was full randomized block, while in the second year, it was full randomized split-split plot block design, in three repetitions. The results showed that in the FI treatments, the yield was increased up ...

in order to investigate the possibility of fennel autumnal sowing in mashhad condition, 2 sets of experiments were conducted in agricultural college, ferdowsi university of mashhad in 2003-2005. this experiment was performed in the manner of split blocks based on completely randomized blocks with three replications. treatments were two fennel ecotypes (khorasan and kerman) and three planting da...

     Selenium has a protective and positive effect on the quantitative and qualitative characteristics of the plants. In order to investigate the effect of selenium foliar application on leaf proline content and some quantitative and qualitative characteristics of rapeseed cultivars under end-season thermal stress, a factorial split plot experiment was conducted in a randomized complete block d...
