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,...

Field experiment was carried out at Ornamental Nursery, Department of Horticulture, Khyber Pakhtunkhwa (KP) Agricultural University Peshawar, during 2009 to study “the response of plane tree cuttings to different planting dates”. Three types of cuttings (hardwood cuttings, semi-hardwood cuttings, Softwood cuttings) and three dates (6 January, 21 January and 5 February) were studied. The experim...

Neotephritisfinalis (Loew) (Diptera: Tephritidae), and sunflower bud moth, Suleima helianthana (Riley) (Lepidoptera: Tortricidae) are major head-infesting insect pests of cultivated sunflower (Helianthus annuus L.). Planting date was evaluated as a cultural pest management strategy for control of N. finalis and S. helianthana in several production regions of North Dakota during 2009 and 2010. R...

In order to investigate the effect of effect of date and depth of tuber cultivation on some agronomic traits of potato cultivars in autumn and spring cultivations, a split factorial experiment was carried out based on randomized complete blocks design with three replications in Ardabil Agricultural and Natural Resources Research Station during the two cropping year 2017-2018. Planting date as t...

Maize (Zea mays) has traditionally been a major cereal staple in southern Ghana. Through breeding and other crop improvement efforts, the zone of cultivation of maize has now extended to the northern regions of Ghana which, hitherto, were the home to sorghum and millet as the major cereals. Maize yield in the northern Ghana is hampered by three major biophysical constraints, namely, poor soil f...

Transplanting or pot culture has been mentioned as a promising approach to increase crop yield and decrease irrigation water use in recent years. Using simulation models to assess pot culture is a valuable way in investigating the effect on yield, water consumption and other properties of crops such as soybean. For this purpose, several pot culture levels (seedling sizes) plus direct sowing wer...

In order to make mechanized planting economically viable, the present spring planting period for Norway spruce (Picea abies (L.) Karst.) seedlings in Scandinavia needs to be extended. To evaluate the possibilities to extend the planting period, six field experiments were established in four years during which frozen-stored, dormant seedlings and actively growing seedlings targeted for spring pl...
