Abstract

This study aims to determine the effectiveness of betel leaf extract (Piper betle) on the control of leaf rust disease Phakopsora pachyrhizi soybean plants. The research was carried out by UPT Palawija Crops, Department of Agriculture of the Province of North Sumatra Tanjung Selamat, Deli Serdang with an altitude of ±25 meters above sea level with a flat topography. The research method used a non- factorial randomized block design consisting of 4 treatments and 3 replications. The treatments tested were K0 = control, K1 = 0.25% extract concentration, K2 = 0.50% extract concentration, K3 = 0.75% extract concentration. Parameters observed were the percentage of infected plants, disease intensity and seed weight of 100 grains. The results showed that the pesticide of betel leaf (Piper betle) had a significant effect in controlling leaf rust disease Phakopsora pachyrhizi. The treatment was in K3 (0.75% extract) with a percentage of 2.1% being attacked. Compared to treatment K0 (Control) the percentage of infection was 6.9%, K1 (Extract 0.25%) percentage was attacked by 5.7%, and K2 (Extract 0.50%) the percentage was 3.2%. The conclusion of this study Betel leaf vegetable pesticides (Piper betle) are effective in controlling leaf rust disease Phakopsora pachyrhizi and can suppress the intensity of P. pachyrhizi attacks on soybean plants so that growth is not disturbed. Betel leaf extract (P. betle)) which was tested had a significant effect on controlling leaf rust (P. pachyrhizi) on soybeans (Glycine max. L) in K3 treatment with the percentage of infected plants being 2.1%.

Abstract

This research was carried out at the PTPN III Sarang Giting plantation, Afdeling II, which is located in Sarang Giting Village, Dolok Masihul District, Serdang Bedagai Regency, North Sumatra Province. Venue Altitude 30m above sea level (asl) and flat land topography. The purpose of this study was to determine the effect of stem circumference and production of rubber plants (Hevea brasiliensis Muell. Arg) on ​​potassium (KCl) combined with agricultural lime (CaCO3) and magnesium (MgSO4) and their effect on the dynamics of soil K levels. This study used a factorial randomized block design (RBD) with 3 (three) factors studied, namely the agricultural lime application factor (C), which consisted of C0 = control and C1 = 1500g/tree/year. The second treatment factor was giving magnesium (M) which consisted of M0 = control, M1 = 1500g/tree/year, M2 = 3000g/tree/year, and M3 = 4500g/tree/year. The third treatment factor was the provision of potassium (K) consisting of K0 = control, K1 = 500g/tree/year, K2 = 1000g/tree/year, and K3 = 1500g/tree/year. The results showed that the administration of potassium combined with the application of agricultural lime and magnesium had a significant effect on the growth parameters of stem circumference. Potassium application combined with agricultural lime and kiserite also had a significant effect on the dynamics of K levels in the soil. However, it did not significantly affect the production of liquid latex
