A synopsis of Plazia Ruiz & Pav. (Onoserideae, Asteraceae) is presented, including the description of a new species, Plazia robinsonii M.O.Dillon & Sagást., from a locality c. 20 kms west of Huamachuco, Department of La Libertad in northern Peru. It most closely resembles Plazia conferta Ruiz & Pav., a narrow endemic from central Peru some 450 km to the south; however, the latter species has la...

in order to investigate genetic correlation and path analysis between grain yield and yield components, fifteen early maturing hybrids of grain corn (zea. mays) using a randomized complete block design with 4 replications were evaluated in khoramabad agricultural research center, iran. the data were collected and analyzed for ear emergence date, anthesis date, maturity date, plant height, ear h...

experiments were conducted at the horticulture research farm of horticulture department, bangabandhu sheikh mujibur rahman agricultural university (bsmrau), salna, gazipur during december, 2007 to may, 2009 to investigate the effect of bulb cutting and potting media on propagation of hippeastrum. the bulb cutting significantly influenced all the parameters except days required to first leaf eme...

Improvement of seed yield and oil content in safflower (Carthamus tinctorius L.) as an oilseed crop is the main objective of its breeding programs. However, little genetic information is available for these traits. The main objective of this study was to estimate genetic parameters for seed yield and oil content. Six safflower lines each derived from different Iranian local populations and Saff...

to investigate the effect of wild mustard plant density and nitrogen fertilizer on morphological characters, yield and yield components of canola a split-plot experiment based on a randomized complete block design with 3 replications was carried out in bu-ali sina university of hamedan, in 2009. 4 levels of nitrogen fertilization (100, 150, 200 and 250 kgn h-1) were assigned to main-plots and p...
