Abstract


Mungbean (Vigna radiata L.) productivity in dryland decreased recently due to the soil fertility degradation. The objective of this study was to evaluate the effect of biochar types and cattle manure rates on the growth of mungbean in semi-arid dark soil. The factorial completely randomized block design 3 x 5 with four replicates was set to arrange treatments for the field trial. Two biochars (rice husk and sawdust) at 10 t/ha in combination with four rates of cattle manure (1, 3, 5 and 10 t/ha) and control (without biochar and cattle manure) were applied to the soil, incubated for three weeks and then planted with mungbean cv. Fore Belu. The results revealed that additions of biochar and cattle manure increased soil moisture and soil electrical conductivity by 2-4% and 0.15-0.20, respectively; decreased soil temperature and bulk density by 1-2oC and 0.2 g/cm3, respectively; increased plant height, stem diameter, root length, total, shoot and root dry weights by 4 cm, 0.1 cm, 5 cm, 7 g, 0.9 g and 6 g, respectively, compared to the control. The best growth of mungbean was obtained from the additions of sawdust biochar at 10 t/ha and cattle manure at 3 t/ha.
