Effects of Mist, Irrigation and Plant Density on Quantitative Aspects of Vegetative and Reproductive Characteristics of Buckwheat (Fagopyrum esculentum Moench)

In order to study the effects of irrigation, mist and plant density on quantitative aspects of vegetative and reproductive characteristics of buckwheat (Fagopyrum esculentum), an experiment was conducted in split split plot, based on RCBD with three replications, during 2001 in experimental station, College of Agriculture, Tehran University. Effects of three factors, including air humidity, irrigation and plant density were considered. Mist and non-mist were arranged in main plots and another three factors including soil moisture or irrigation levels (20 mm and 40 mm), planting density levels (100 and 33/3 plant per m2), were arranged in subplots.The effect of these factors and their interactions were studied on characters including: 1000-seed weight, yield of seed per plant, number of seed per plant, plant height and biomass dry weight. Results showed that the both main and interaction effects of main and subfactors were significant on some characters including number and amount of seed per plant, 1000-seed weight and plant dry weight.Treatment of mist, 40 mm water irrigation and density of 33/3 plant per m2 showed the highest effects on all characters
