Pengaruh macam dan kadar pupuk daun terhadap hasil teh terserang cacar. Teh effect of kind and concentration of foliage fertilizer to tea growth attacked by Exobasidium vexans Massee.

Teh objective of the research was to know the effect of kind and concentration of foliage fertilizers to tea growth attacked by Exobasidium vexans Massee. The experiment was carried out at Sirebut block in Pagilaran Tea Estate from February 1999 to May 1999. The design used was Randomized Complete Block Design with three replications. The treatments were Gandasil D (concentration : 1 g/1, 2 3 gl1), Bayfolan (concentrations : 1m1/1, 2 m1/1, 3 m1/1) and Supergreen (concentration : 1 m1/1, 2 m1/1, 3 m1/1) and no fertilizer applied as control. The result indicated that the application of Bayfolan 2 m1/1 resulted the total leaves weight, number of peco shoot, percentage of number of peco shoot, and relative growht rate higher and others treatment, while the percentage of banjhi shoot was lowest. The foliage fertilizer have no effect to blister blight intensity. Keywords :Foliage fertilizer, tea, Exobasidium vexans Massee. Penelitian ini bertujuan untuk mengetahui kemampuan tiga macam pupuk daun dan konsentrasi untuk meningkatkan pertumbuhan kembali pucuk teh terserang cacar. Penelitian dilaksanakan di lokasi Sirebut, kebun PT Pagilaran, kecamatan Blado, kabupaten Batang, Jawa Tengah, mulai bulan Pepruari 1999 sampai dengan Mei 1999. Penelitian menggunakan Rancangan Acak Kelompok Lengkap (RAKL) dengan 3 blok dan 10 perlakuan, yaitu : Gandasil D dengan konsentrasi I WI, 2 g/l, 3 g/lBayfolan 1 min, 2 m1/1, 3 m1/1Supergreen 1 m1/1, 2 mI/1, 3 m1/1, serta kontrol. Hasil penelitian menunjukkan bahwa perlakuan Bayfolan 2 m1/1 menghasilkan berat total, jumlah pucuk peko, berat pucuk peko, prosentase jumlah pucuk peko, dan kecepatan pertumbuhan relatif (RGR) lebih tinggi dibandingkan perlakuan lainnya sedangkan persentase pucuk burung paling rendah. Perlakuan pupuk daun tidak berpengaruh terhadap penurunan intensitas serangan cacar. Kata kunci : pupuk daun, teh, cacar dau
