Influence of humic acid on asparagus (Asparagus officinalis L.) shoots yield quality

The main objective was to evaluate the effect of humic acids on the shoots yield and quality of asparagus (Asparagus officinalis L.) Experiments were carried out in 2014. ASU of Agriculture and Food Sciences Institute. Experiments have shown that fertilization with humic acids had no significant influence of asparagus (Asparagus officinalis L.) shoots yield. The biggest total yield was (3540.4 kg ha-1) of shoots, total marketable yield was (2671.1 kg ha-1) of shoots, fertilization with the highest rate of humic acid 7.5 kg ha-1. The minimum total yield (2694.7 kg ha-1) and marketable shoots yield (2265.0 kg ha-1) was the control (N5P10K25). The biggest mass of shoots (14.0 g) the biggest shoots length (17.9 cm) and the biggest diameter of shoots (1.44 cm) was fertilization with the highest rate of humic acid 7.5 kg ha-1 . Shoot mass and length had no significant influenceVytauto Didžiojo universitetasŽemės ūkio akademij
