in order to study the effects of intra and inter-row spaces and planting pattern on the yield components, seed and oil yield of pumpkin (cucurbita pepo l.), a field experiment was conducted as split-split plot based on randomized block design with three replications during 2009-2010 at the agricultural research station of ferdowsi university of mashhad, iran. two levels of inter-row space (1 an...

Cotton is an important cash crop worldwide, accounting for a large percentage of world agricultural exports; however, yield per acre is still poor in many countries, including Pakistan. Diallel mating system was used to identify parents for improving within-boll yield and fiber quality parameters. Combining ability analysis was employed to obtain suitable parents for this purpose. The parental ...

Correlation coefficient and path analysis studies was conducted with eight parents and their 28 F1 crosses for twelve component characters including seed yield and revealed significant positive association of pods per plant, harvest index and clusters per plant with seed yield in parental generation whereas in F1 generation, significant positive association of clusters per plant, pods per plant...

Dust seeds are the smallest seeds in angiosperms weighing just about a few micrograms. Th ese seeds are characteristic of most orchids, and several studies have been performed on seed features, fecundity and dispersal of orchid dust seeds. In this study we examine seed features, seed production and seed dispersal in another plant group with dust seeds, the Pyroleae (Monotropoideae, Ericaceae), ...

In order to study the effect of vermicompost and nitrogen fixing bacteria on seed yield, yield components of seed and essential oil content of coriander (Coriandrum sativum), an experiment was conducted as factorial experiment in the base of randomized complete blocks design with eight treatments and three replications at research field of Agriculture Company of Ran in Firouzkuh of Iran in 2012...

Screen house trials consisting five plant extracts including a synthetic fungicide (Azadirachta indica, Jatropha curcas Linn., Alium sativum, Ocimum gratissimum, Chromolaena odorata and Benlate ) were tested at the Taraba State University(TSU) Research Farm centre (Ardokoa: Latitude 08 0 53′N and Longitude 11 0 19′E) in a completely randomized design arrangement. The results of the screen house...

Five insect biological control agents that attack flower heads of spotted knapweed, Centaurea stoebe L. subsp. micranthos (Gugler) Hayek, became established in western Montana between 1973 and 1992. In a controlled field experiment in 2006, seed-head insects reduced spotted knapweed seed production per seed head by 84.4%. The seed production at two sites in western Montana where these biologica...
