| dc.description.abstract | The objective of this study were to know the effect of second KCl fertilizer and rice straw on growth and production of sweet potato clones Ayamurashake. The experiment was conducted in farmers' fields Cikarawang Village, Dramaga District, Bogor Regency is located at an altitude of 300 m above sea level. This research used Completely Randomized Design Group (RKLT) with two factors, with continue test Duncan Multiple Range Test (DMRT) at level 5 %. The first factor is the dose of KCl in the second fertilization with two levels: without KCl (K0) and with KCl 100 kg / ha (K1). The second factor is aplication of rice straw with two levels: without rice straw (J0) and rice straw 7 tons / ha (J1). The results showed the second KCl fertilization with 100 kg / ha no longer can increase the growth and production of sweet potatoes because the content of K in the soil is already quite high. Rice straw with a dose of 7 000 kg / ha not been able to increase growth and sweet potato production significantly, although there is a tendency to increase.The second of fertilization KCl and / or rice straw to reduce the weight of diseased tubers. | en |
