rapeseed as one the most crops is the basic needs of human feeding in order to produce oil. a field experiment was conducted to study the effects of different tillage system, seeding method and rates on yield and its components, as well as, seed oil percentage of rapeseed (brassica napus l. cv. hyola-401) during 2011-12 growing season at rice research institute of iran-department of mazandaran ...
Knowledge of the effects of row spacings and seeding rates on dual-purpose forage and seed production of an annual legume crop is essential for its proper agronomical exploitation. In this study, the effects of various row spacings and seeding rates on dry matter and seed yield in berseem clover (Trifolium alexandrinum L.) were evaluated in two consecutive years. The experimental design was a s...
Hybrid rice and insecticide seed treatments targeting rice water weevil, Lissorhoptrus oryzophilus Kuschel, have altered the landscape of rice production. The effect of reduced seeding rates on seed treatment efficacy in hybrid rice has not been studied. During 2011 and 2012, an experiment was conducted at seven locations to determine the relationship between low seeding rates used in hybrid ri...

In order to evaluate the effects of planting methods and seeding rates on growth characteristics and yield of alfalfa (Medicago sativa L.), Hamedani cultivar, a field experiment was conducted in 2008 at College of Agriculture, Shiraz University, Iran. The experimental design was a completely randomized block with four replicates in a factorial arrangement of the treatments. The factors consiste...
abstract previous researches have shown success of growth hormones usage on flower production increase, pod and prevention of abscission of them in some of the pulses. two tests were done, in order to find out the effects of growth hormones to on flower production increase, pod and chick pea yield composites in farmer conditions (2010-11) and green house conditions as factorial on the proje...
We studied the rates of seed removal by different granivores, in different microsites, at different times, in a Patagonian shrub steppe in South America. Granivory rates of exotic (Phalaris canariensis) and native (Mulinum spinosum) seed species were an order of magnitude lower than those reported for another cool desert from North America with comparable climatic conditions. Insects and rodent...

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...
Climate change affects communities both directly and indirectly via changes in interspecific interactions. One such interaction that may be altered under climate change is the ant-plant seed dispersal mutualism common in deciduous forests of eastern North America. As climatic warming alters the abundance and activity levels of ants, the potential exists for shifts in rates of ant-mediated seed ...
