Abstract:
The aim of this research is to study the effect of biochar, an organic fertilizer on the
physiological parameters of growth (height, number of leaves) and yield (weight) of amaranth
cultivation. To carry out this research, a completely randomized Fisher block device was fixed in
an experimental station with 3 repetitions and 4 treatments. The R.3.0.0 software was used to
analyze the data. The results showed that the corn stalk biochar has an average density of 0.26
g/cm3 and 0.32 g/cm3 for the peanut hull biochar. These types of biochar have mass yields of
25.61% and 26.75% respectively and average durations of 503' 48" and 660' 27''. The treatments
days after transplanting significantly influenced (p < 0.05) the physiological parameters (height
and number of leaves) and the yield of the amaranth plants. The T2 treatment (75% corn stalk
biochar and 25% groundnut fane biochar) performed best in plant height (21. 94 cm), number of
leaves (14) and weight (3. 17 t/ha). The mixture of 75% of corn stalks biochar and 25% of
biochar from peanut haulm can therefore contribute to a better yield of amaranth cultivation and
ensure the sustainability of vegetable production. |
