FIELD PERFORMANCE OF A FLUID DRILL |
| Author: | S.M. Ward |
| Abstract:
Fluid drilling is a technique whereby seeds are dispersed in a fluid medium and subsequently extruded into the soil. It offers the possibility of sowing either imbibed or pre - germinated seeds. A fluid drill, with rotary self-cleaning rotors, was developed; and field tests were conducted on both cabbage and Spring - sown onions. Results indicate that, while inferior spacing distributions were obtained, nevertheless, fluid drilled pre - germinated crops compared favourably with conventionally drilled crops. For example, emergence occured approximately 30% sooner; and crop growth and vigour was comparable with that of conventionally sown crops. | |
