the purpose of this study was to determine the plant density of sugar beet fields in qazvin region using satellite images and remote sensing techniques. the plant density can be used to estimate the pre-harvest sugar beet yield and as a result the proper management of agricultural and industrial processes involved in sugar production. satellite data can be used to remove the cost and time of co...

in the present experiment, the effects of nitrogen and phosphor fertilizer application in two methods of furrow and trickle irrigation on the yield and quality of sugar beet seed cultivar 7233 were studied. the experiment was conducted as a split factorial in a completely randomized block design with three replications during 2003 and 2004 in hamedan province. main plots were allocated to irrig...

in this study, analysis of actual data collected from sugar beet hybrid monogerm seed producers in the 2001 growing season and laboratory seed samples showed that delay in steckling sowing resulted in the reduction of raw and pure sugar beet seed yield and the increase of undersize seed portion. non-significant effect of sowing dates on unkernel seed percent showed that the high temperatures wi...

for determination of water stress effects in different growth stages of sugar beet and optimum water usage on quantity and quality of sugar beet, this study was performed using randomized complete blocks design in factorial experiment with 12 treatments and 4 replications from 1999 to 2001 in agricultural research center of hamadan. the first factor was non-irrigation in 3 stages of growth (s1-...

crop yield estimation is one of the most important parameters for information and resources management in precision agriculture. this information is employed for optimizing the field inputs for successive cultivations. in the present study, the feasibility of sugar beet yield estimation by means of machine vision was studied. for the field experiments stripped images were taken during the growt...
