| Abstract:
A nutritional study with asparagus clones found that a growth rate maximum was not attained when the plants were fed daily with a 100 mgl-1 N, 34 mgl-1 P, 100 mgl-1 K nutrient feed. Clones were grown for 4 weeks at 14°C, 21°C, 28°C in growth cabinets. At 14°C the clones did not grow, while growth increased over the temperature range to 28°C. As temperature increased so did partitioning of dry matter to the shoots. In an establishment trial in the field, planting both seedlings and clones through black polythene mulch increased plant dry weight at the end of the growing season. The seedlings partitioned 40% of their dry matter to the shoots whereas the clones only 26%. Experience has shown that after transfer out of tissue culture the growth of asparagus clones does not compare with that of seedlings. Possible reasons for this are discussed. | |
