Respon Pertumbuhan dan Produksi Tanaman Cabai Merah (Capsicum Annuum L) dengan Pemberian Biochar dari Kendaga dan Cangkang Biji Karet pada Berbagai Tanah di Lahan Bekas Penanaman Tanaman Hortikultura di Kabupaten Karo

Abstract

Seriusman Zai, Growth Response and Production of Red Chili Plants (Capsicum Annuumm L) With the provision of Biochar from kendaga and rubber seed shells on various lands in the former planting of horticultural crops in Karo District. Guided by Dr. Ir. Sumihar Hutapea. MS and Ir. Rizal Azis, MP. This study aims to determine the growth and production response of red chilli (Capsicum Annuum L) with the provision of biochar from kendaga and rubber seed shells in various soil in the former land of horticulture cultivation in Karo Regency is best for the growth and production of red chilli plants. This research was conducted at Kasa Growth Center Kopertis Region I North Sumateta - Nangroe Aceh Darussalam from June to October 2016. Research was done by planting in polybag with 10 kg weight / polybag. This research was conducted by using Factorial Randomized Block Design (RAK) with 2 treatment factors. The first factor is Biochar Kendaga and Rubber Seed Rubber consisting of 4 dosage levels: B0 = (control), B1 = (5 ton / Ha or 25 g / polybag), B2 = (10 ton / Ha or 50 g / polybag) , B3 = (15 tons / ha or 75 g / polybag). The second factor is the various land used in horticultural agriculture found in brastagi regency karo north sumatera which intesif the use of pesticide and fertilizer which consist of 3 level which is: T0 = Land at research location Growth Center Kopertis Region 1 Sumut-Aceh, T1 = polluted land Fertilizer and inorganic pesticide from Guru Singa Village of Brastagi Subdistrict, Karo Regency, T2 = Soil contaminated with fertilizer and inorganic pesticide from Sukanalu Village, Brastagi Sub-district, Karo Regency. The results showed that Soil Treatment (T) had a significant effect on the growth of red chilli plant, that is observation of high plant parameter aged 4 - 8 MST, and had no significant effect on age 2 and 3 MST. After that, the observation of leaf number parameters at age 3,4 and 5 MST had very significant effect, significant at age 6,7, and 8 MST and not significant at age 2 MST. Furthermore, to observe the stem diameter of 2-8 MST have a very significant effect. Observation of productive branch parameters at first, second and third observation have no significant effect. Observation of first, second, and third crop harvest parameters was not significant. While for observation of the first, second and third harvest fruit bobot parameters have no significant effect. Biochar treatment from kendaga and rubber seed shells had no significant effect on vegetative growth and generative of red chilli plant on all observation parameters. The interaction between the used soil treatment and biochar from kendaga and rubber seed shells had no significant effect on all observation parameters.
