PENGARUH PEMBERIAN PUPUK KANDANG KAMBING DAN PESTISIDA NABATI TERHADAP PERTUMBUHAN DAN PRODUKSI TANAMAN KEMBANG KOL (Brassica oleracea L.)

Abstract

The Effect of Goat Manure and Vegetable Pesticides on the Growth and Production of Cauliflower (Brassica oleracea L.)", under the guidance of Mrs. Ir.Rosmalina Sinaga ,MP (Advisor I) and Mrs. Ir.Saudur Simangunsong MSi (Advisor II). Who carried out the research in the experimental field of the Faculty of Agriculture, University of Sisingamangaraja XII Tapanuli with an altitude of ± 1400 m above sea level. Research implementation from July to October 2021.The design used in this study was a factorial randomized block design (RAK) with two factors, namely: Factor I Provision of Goat Manure with 4 levels, namely: K0 (Without Treatment), K1 (4 kg), K2 (8 kg) and K3 ( 12 kg) and Factor II Provision of Vegetable Pesticides P0 (Without Vegetable Pesticides), P1 (Papaya Leaf Vegetable Pesticides P2 (Soursop Leaf Vegetable Pesticides) and P3 (Garlic Vegetable Pesticides)Thus obtained 16 treatment combinations and from treatment with 3 replications. Parameters observed were: plant height (cm), number of leaves (strands), flower diameter (cm) stover weight (kg), production weight/sample (grm), production weight/plot (kg), pest attack intensity (%) and intensity of disease attack (%).The results showed that the application of goat manure and vegetable pesticides had a very significant effect on plant height (cm), number of leaves (strands), flower diameter (cm), stover weight (kg), production weight/sample (grm), production weight/ plot (kg), pest attack intensity (%) and disease attack intensity (%).The interaction between goat manure and vegetable pesticides had a very significant effect on plant height (cm), number of leaves (strands), flower diameter (cm), stover weight (kg), production weight/sample (grm), production weight/plot (kg) intensity of pest attack (%) and intensity of disease attack (%).
