Pengaruh Pupuk Organik Dan Pupuk Hayati Terhadap Pertumbuhan Bibit Kakao (Theobroma Cacao L.) Kultivar Upper Amazone Hybrid – The Effect of kasting as organic fertilizer and biofertilizer on Growth of Cacao Seedlings (Theobroma cacao L.) Upper Amazone Hybrid (UAH) Cultivar

Suatu penelitian untuk menelaah pengaruh pupuk organik kascing dan pupuh hayati terhadap pertumbuhan bibit kakao (Theobroma cacao L) kultivar Upper Amazone Hybrid telah dilaksanakan di PTPN VIII Kebun Rajamandala Kabupaten Bandung mulai bulan Juli 2007 sampai dengan bulan November 2007. Rancangan percobaan yang digunakan adalah Rancangan Acak Kelompok (RAK). Adapun perlakuannya adalah A = 100 % anorganik; B = 10 g kascing + 100 % anorganik; C = 10 g kascing + 50 % anorganik ; D = 20 g kascing + 100 % anorganik; E = 20 g kascing + 50 % anorganik; F = 10 g PHE + 100 % anorganik; G = 10 g PHE + 50 % anorganik ; H = 20 g PHE + 100 % anorganik ; I = 20 g PHE + 50 % anorganik. Terdapat 9 perlakuan yang diulang 3 kali Hasil percobaan menunjukkan bahwa tidak terdapat perbedaan yang nyata pengaruh pupuk organik kascing dan pupuk hayati terhadap tinggi tanaman, diameter batang bobot kering tanaman dan jumlah daun bibit kakao,bobot kering total tanaman. Namun demikian terdapat perbedaan pengaruh pada jumlah daun umur 8 Minggu Setelah Tanam yaitu perlakuan 10 g kascing + 50 % anorganik memberikan jumlah daun yang lebih banyak.

An experiment to evaluate the effect of kasting as organic fertilizer and biofertilizer on on Growth of Cacao Seedlings (Theobroma cacao L.) Upper Amazone Hybrid (UAH) Cultivar was conducted at the PTPN VIII Rajamandala Distric Kabupaten Bandun,, from July until November 2007. The design of the experiment was randomized block design. There were nine treatmens : Each treatment for a polybag were contained : A = 100 % anorganic; B = 10 g kascing + 100 % anorganic; C = 10 g kascing + 50 % anorganic ; D = 20 g kascing + 100 % anorganic; E = 20 g kascing + 50 % anorganic; F = 10 g biofertilizer + 100 % anorganik; G = 10 g biofertilizer + 50 % anorganik ; H = 20 g biofertilizer + 100 % anorganik ; I = 20 g biofertilizer + 50 % anorganik. The treatment was replicated three times, so there were 27 treatmens. Each treatment consisted 5 plants. The result of the experiment showed that casting as organic fertilizer and biofertilizer were not gave effect on, plant height, stem diameter, leave count, root dry weight, stem weight, and total dry weight. Casting 20 g per polybag and 50 % anorganic gave good effect on leave count 8 MST.
