Abstract:
The pot experiment was caried out to study the effect of compost and green
biomass mixture on the growth and the production of chili. Rice straw and com
stalks were the domestically accessible crop residue were used main compost
material, and green leaves of Ipil-ipil and wild sunflower were used as green
biomass material. An experimental was laid out in a complete randomized design
(CRD) with two replicates having the following Treatment: T1 Crop residue
compost only 1Kg- control treatment, T2 Crop residue compost + Green biomass
at 750:250 g rate, T3 Crop residue compost + Green biomass at 500:500g rate, T4
Crop residue compost + Green biomass at 250:750g rate, T5 Crop residue
compost + Green biomass at 600:400g rate, T6 Crop residue compost + Green
biomass at 400:600g. M2 variety of chili plants were planted in prepared potting
media in a polythene bag and all other agronomic practices were done as
recommended by the Department of Agriculture, Sri Lanka. Growth parameters
were measured from the 2nd week up to the 8th week after planting and yield
parameter was taken 10th week. Then data were analyzed statically using mini tab
17. The result showed that different rates of compost mixed green biomass had a
significant effect on some tested parameters of chili over the control. The result
revealed that application of T6 Crop residue compost + Green biomass at
400:600g significant differences in growth and yield parameters than other
treatments. Which suggested Application of crop residues compost 400g and a
combination of green biomass 600g would be the suitable rate for optimum plant
growth and yield
