Response of Drilled Early Corn to Several Plant Populations

Corn Response to within Row Plant Spacing

Key planting factors that influence corn stand establishment includes uniform depth and spacing of seed, correct seed population and optimizing the soil environment for rapid germination and uniform emergence. Other variables affecting stand establishment are seedbed quality (including soil moisture and temperature), seed quality and planter speed. Differences among fields for stand establishme...

Corn production and plant characteristics response to N fertilization management in dry-land conventional tillage system

Nitrogen (N) application management needs to be refined for low yielding environments under dryland conditions. This 3-yr study examined nitrogen fertilization management effects on corn (Zea mays L.) plant characteristics and grain yield in rain fed environment under conventional tillage system. Nitrogen fertilization management consisted of two timing methods of N application [all N at planti...

Micro Morphological Study of Several Populations of Zataria multiflora Boiss.

Zataria multiflora Boiss. is  one of the most important species of the Lamiaceae family, which has numerous medicinal properties in traditional medicine, and is related to the thyme species in terms of botanical features and composition of essential oil. In this research, the anatomical characteristics of vegetative organs including leaves, inflorescence, stems and petioles of 4 popula...

Determination of Early Stage Corn Plant Height Using Stereo-vision

Periodic measurements of plant height could be used to calculate growth rate and have potential for characterizing spatial variation of plant response to inputs and field conditions. A corn plant height measurement system using stereo machine vision was developed. A test apparatus was developed, which consisted of an x-y translating sensor platform with a CCD camera and an imaging stage for cam...
