The effects of narrow point's geometry on emergence and crop establishment of wheat in a sandy loam soil
Numerous seeding points have been developed for sowing under dryland conditions. Although some improvement has been made, there are still problems with penetration of ground engaging tools, provision of a desirable seedbed environment, uniform seed placement, and root growth when sowing into untilled soil. Narrow points have reasonable capability to alter these and maintain growth potential in a wide range of soil conditions.
This study investigates the effect of variation in wing and slotting blade size of narrow points on soil physical conditions and crop growth parameters in order to develop the narrow-winged-bladed points geometry that best suits direct drilling under hard soil conditions of no-till practices in dryland regions
