Plugs are rapidly replacing fresh-dug bare-root and cold-stored frigo plants as transplants for strawberry (Fragaria ×ananassa) production worldwide. Plugs have many advantages over these other types of propagules. They are grown in controlled environments (greenhouses, tunnels) in less time than field produced bare-root transplants, and are not exposed to soilborne pathogens. Plugs afford grea...
The paper using the inverse kinematics theory of the parallel mechanism , studied the movable needs of the transplanting robot,deduced the inverse kinematics formula of transplanting robot.Considered the demand of the “fetch and plant”operations,made an important research on the two trajectory planning methods of the moving platform: quintic and septic polynomial motion laws, acquired their var...
Nutrient loading can improve the growth and nutrient content of nursery-grown Betula alnoides Buch.-Ham. ex D. Don, but it is unknown whether enhances uptake after transplanting. Plants were grown with three treatments (N100, N200, N400; 100, 200, 400 mg N per plant as 15N-urea) in nursery containers then transplanted into plastic pots, or without controlled-release fertilizer (F0 F10, 0 10 g p...
It is important to determine the appropriate planting density in the conditions of using old seedlings of paddy rice. For this purpose, a field experiment was conducted as a randomized complete block design at Qaemshahr, Northern Iran, in four replications and in two years, 2020 and 2021. Plant densities consisted of manual-traditional planting of up to 11 hills/m2 (with unequal planting spaces...
In order to evaluate the effect of age of transplant and seeding rate used in transplanting on yield and yield components of rice cultivar Sazandegi, a two-year study (2007-2008) was carried out in Isfahan Agricultural Research Center (Fozve station) by using split plot randomized based on complete block design in three replications. Three transplant ages (25, 30, and 35 day) were assigned as m...
