Pengaruh pemupukan lewat daun terhadap produksi kopi
This paper reports the results of a foliar fertilization on coffee on the Silosanen Estate, Jember, during the 1976 dry season. The coffee leaves were deficient in N, Mg and Mn. It showed that spraying of coffee leaves with 1 MgSO4 and 0,2 MnSO4, during the 1976 dry season (July to Oct. 1976), could change the yellow colour of the leaves into green. The dosage of fertilizer used for every application was 10 kg urea, 10 kg MgSO4, 2 kg MnSO4, 200 cc Citowett, diluted in 1000 1 of water for each hectare. The increase of market coffee yield obtained was about 300 kg/ha, while the total spraying cost was Rp.31.000,-/ha. It is concluded that foliar fertilization is profitable
