in other to evaluation of morphological and phenological traits of 24 populations, from four species chamomile of the genus of anthemis, an experiment were carried out using randomized completely blocks design (rcbd) in three replications in alborz research station in karaj, iran during 2011-12. 13 traits including: length and width of canopy diameter, plant height, number of flower, shoot fres...

The crop nutrition has a well-defined effect on yield and quality of forage crops. Among various essential macro nutrients, the nitrogen has a key function in improving forage yield and crude protein contents but demand of crop for nitrogen varies with the cultivars. The present study was conducted to investigate the effect of different nitrogen levels (0, 25, 50 kg ha) on forage yield and qual...

chemical fertilizers are threat in hman life and today application of biological fertilizer find more important. this study performed in order to evaluate the effects application of biofertilizers with urea fertilizer on yield, protein percentage and numbers of eyes in plant, plant height and chlorophyll spad in potato var. marphona. a factorial experiment was conducted based on randomized comp...
