Abstract:
The performance of radish plants which were grown under fertilizers by using biogas residual solids (BGRS) has been studied in diameter of the tubers, height of the plants, number of leaves, leaf area (LAI). The performance evaluation was conducted under seven different variations of treatments, biogas residual solids and poultry litter, biogas residual solids and gliricidia leaves, biogas residual solids and weed rash, biogas residual solids and sludge, normal compost, only biogas residual solids, only surface soil (every treatments contain 1:1 ratio surface soil). Every treatments was conduct under same environmental condition and same period of times. According to the statistical analysis treatment 2 and treatment 4 were taken as best treatments.
This was carried out with average diameter of the tubers16.813 ± 0.489 of treatment 4 and 16.453+ 0.280of treatment 2, average height of the plants 34.947 ± 0.480of treatment 4 and32.387 ± 0.304 of treatment 2, average number of leaves 6.933 ± 0.11 of treatment 4 and 6.267 ± 0.64 of treatment 2, average leaf area 42.060 ± 0.50 of treatment 4 and 40.693 ± 0.73 of treatment 2
