To investigate the effect of depth of planting holes on yield and yield components of three cultivars of watermelon in dry land conditions, a two-year study (2006-2007) was carried out in Varamin Agricultural Research Center, using a split plot randomized complete blocks design in three replications. Three cultivars of watermelon (Mahbube, Charleston Gray and Sugar Baby) were assigned to main p...
in order to study the phonological stages and growth period of invasive weed ranunculus ficaria based on degree days and to study the effect of planting depth on sprouting the tubers roots of this weed, two separate experiments were conducted in crd with 5 replications at ferdwosi university of mashhad in 2008. in the first study germinated tubers were planted in 5 cm depth and the observations...
Current planting depth recommendations for corn (Zea mays L.) producers range from 38 to 51 mm in the midwestern United States. Characterization of emergence and soil conditions at a depths under later-planted scenarios is important as days adequate field work April have been reducing may affect dates. Field studies were conducted Ohio 2017 2019 determine effects type on emergence, growth, grai...
in order to study of hydropriming, planting depth and nitrogen split application effect on yield and yield components of double cross hybrid of corn, an experiment was carried out as factorial based on randomized complete block design (rcbd) with four replications. nitrogen split application included (400 kg/ha at sowing date, 100 kg/ha at sowing date and 300 kg/ha 25 to 50 days after sowing da...
Agricultural investigations use computer models for simulation of crop growth and field water management. By using these models, the effects of plant growth parameters on crop yields are simulated, hence, the experimental costs are reduced. In this paper, the model of MSM (Maize Simulation Model) was calibrated and validated for the prediction of maize forage production at Agricultural College,...
