in order to evaluate the effect of sowing date and plant density on the morphological triats, yield and yield components of sweet corn (zea mays l. var sc. 403) an experiment was conducted at the khorasan razavi agricultural research and natural resources center, mashhad, iran during 2008. this experiment was carried out as split plot based on rcbd with four replications. the sowing date (14th ...
To evaluate the effect of plant density and detopping on grain yield, protein content biological yield harvest index, growth indices, number of cob in each plant, No. of row per ear, No. of grain in each row, thousand seed weight of corn (Zea mays L. ar. SC 704), an experiment was conducted at the experimental statues of Research Center of Uremia Agricultural College in 2004. The Treatment desi...
Non-trellised culture of tomato is gaining interest among farmers cultivating long shelf-life (LSL) landraces because the reduction in production costs. This cropping system can benefit from selection determinate growth genotypes, mirroring advancements achieved processing tomatoes. With this aim, and profiting natural variation found within Penjar landrace, we selected traditional genotypes br...
We examined the occurrence of brown bear (Ursus arctos) in Finland by using hunterprovided observations and harvest data for 1992–2004. We calculated a simple index (bears observed/ all observation cards) from observation cards filled annually by nearly 5,000 moose hunting clubs. This occurrence index was treated as a dependent variable in a mixed regression model to examine differences between...
This research provides a methodology for estimating the total societal benefit generated from substituting private vehicle trips with public transportation trips. The external costs of and were estimated using base case travel demand model then mode shift was simulated to calculate effects shifting one full transit unit (e.g., bus) mode. performed all origin–destination (O-D) pairs in region fi...
in order to evaluation of plant densities and row spacing effects on growth and yield of wheat, an experiment was conducted by using four plant densities (125, 250, 375 and 500 plants per m2),two row spacing (12.5 and 25 cm), in a randomized complete block design with three replicates in anbare-ololum reign in rainfed and saline conditions during 2008-2009. results showed that leaf area index (...
objective: the objective of this study was to investigate the invitro fluoride release of four new self-adhesive resin cements; set (sdi, australia), breeze (pentron, usa), embrace wetbond (pulpdent, usa), g-cem (gc, japan) and to assess the bonding performance of these self-adhesive resin cements for bonding of orthodontic brackets. materials and methods: for fluoride release experiment, six ...
Despite its economic importance, not much information exists on growth and productivity of durum wheat in Iran and Isfahan. In order to evaluate growth, grain yield, and attributes in three durum wheat genotypes, Osta/Gata, Dipper-6, and PI40100, with five planting densities of 200, 275, 350, 425 and 500 seeds/m2, a four-replicate RCBD field study with a spilt-plot layout was carried out in win...
a number of 36 varieties of rice were compared for different traits. the correlation coefficient of grain yield with tiller number, harvest index, length of grain, ratio of length to width of grain, amylase content, days to 50 percent flowering and days to full maturity were positive and significant (p
