introduction lentil (lens culinaris medik.) is an important legume in the mediterranean area. high protein content in lentil seed (about 22-28%) makes it as a good food source for developing countries and low-income people. in the west of iran such as kermanhah province, it is the most important pulse in rainfed systems cultivated traditionally in rotation with wheat and barley. lentil is grown...

kochia is a halophyte plant and is a good source of forage for livestock under saline irrigation. in order to investigate the salinity effect on morphological and forage characteristics of kochia, an experiment was conducted. three saline waters (5.2, 10.5 and 23.1 ds m-1) and three kochia ecotypes (birjand, borujerd and sabzevar) were allocated as main and sub plots, respectively, in a split p...

this research which aims to survey the relation between tobacco leaf yield and its components is done by using 118 varieties of tobacco in a research farm of guilan tobacco research institute. regarding to five random selections of plants, twenty three traits of each variety were evaluated. correlation between dry matter of leaf yield with plant height, stem diameter, leaf length, leaf width, l...

in order to study the effect of strip intercropping of maize (zea mays l.) and bean (phaseolus vulgaris l.) on the dry matter yield and land equivalent ratio (ler) in weedy and weed free treatments, an experiment was conducted at the agricultural station of college of agriculture, ferdowsi university of mashhad, iran. treatments were strip width of 2, 3, 4 and 5 rows and sole cropping of each c...

A mathematical model is developed for converting between the two measurement bases commonly used in the construction of growth profiles in solid-state fermentation, namely absolute mass ratio m(dry biomass)/m(initial dry matter) and relative mass ratio m(dry biomass)/m(dry matter). These are not equivalent, due to the loss of dry matter as CO2 during the fermentation. The model is equally appli...

sunflower is one of the most important edible oil that growth of annual crops, it is grown over a widely area and is considered a crop adapted to an every environmental conditions, in order to study growth analysis of sunflower under sowing date and cultivars in dry condition a farm experiment was conducted a split plot arranged in a complete randomized block design with three replications in t...

In order to investigate the effect of vermicompost and Nano Iron on yield and yield components of maize, a farm experiment was done in a factorial based on completely randomized blocks design with three repetitions in Damavand in 2013. The first factor was vermicompost in two levels included no applying and applying (vermicompost 1kg.m-2) and the second factor was Nano iron fertilizer with four...
