Abstract:
The status of soil organic matter in Bangladesh is extremely low. To improve the
amount of soil organic matter, it is required to explore the best organic amendment for
better crop production. Thus, a field experiment was conducted in the Agroforestry
Field Laboratory, Sher-e-Bangla Agricultural University, Dhaka during the period
from May to October 2020 to find out the response of different leaf biomass
application on growth and yield of tomato cv. BARI Hybrid tomato 8. Ten
experimental treatments such as T
1
-Control, Recommended dose of fertilizer (RFD),
T
2
= ½ RFD, T
3
= Moringa leaf biomass at 10 g/kg soil, T
4
= Moringa leaf biomass 10
g/kg soil + ½ RFD, T
5
= Moringa leaf biomass 5 g/kg soil, T
6
= Moringa leaf biomass
5 g/kg soil + ½ RFD, T
7
= Ipil-ipil leaf biomass 10 g/kg soil, T
8
= Ipil-ipil leaf biomass
10 g/kg soil + ½ RFD, T
9
= Ipil-ipil leaf biomass 5 g/kg soil, T
10
= Ipil-ipil leaf
biomass
5 g/kg soil + ½ RFD were imposed in this study. The experiment was
conducted in a Completely Randomized Design (CRD) with three replications.
Results showed that green leaf biomass together with ½ RFD substantially or slightly
increased the growth and yield of tomato plant in contrast to ½ RFD and RFD
treatment. The lowest growth and yield is obtained from the ½ RFD. The highest
yield per plant (1.89 kg)
was obtained from T
6
(Moringa leaf biomass 5 g/kg soil + ½
RFD) followed by T
8 (Ipil-ipil leaf biomass 10 g/kg soil + ½ RFD). Among the green
leaf biomass treatment, moringa gave better results than the ipil-ipil. Therefore, this
study suggests that the combined application of green leaf biomass of moringa or ipilipil
with
½
RFD
may
be
used
in
tomato
cultivation.
