Abstract:
The pot experiment was carried out to study the effect of biochar-made kitchen
waste combined with vermicompost on the growth of tomato (Solanum
lycopersicum) plants.
This experiment was laid out in a Complete Randomized Design (CRD) with
replicates having the following treatments: T1- Control (1kg soil alone), T2-
200g vermicompost, + 200g kitchen wastes biochar + Soil 600g, T3-
vermicompost 150g + 400g kitchen wastes biochar + Soil 450g, T4- 100g
vermicompost + 600g kitchen wastes biochar + Soil 300g, T5- 50g
vermicompost + 800g kitchen wastes biochar + Soil 150g.
The results showed that different rates of biochar, and vermicompost had
significant effects on some tested parameters of tomato over the control. The
results revealed that the application of 100g vermicompost and 600g biochar
(T4) had significant differences in plant height. the number of leaves and
branches per plant, stem length, stem weight, root weight, and root length than
other treatments.
Application of biochar mixed with vermicompost improves the growth of
tomato plants in sandy regosol. The present study can be suggested that among
the all tested treatments of biochar and vermicompost mix, the combination of
600g biochar and 100g vermicompost would be the suitable rate for optimum
tomato plant growth.
