Abstract

Cassava (Manihot esculenta Crantz) has a strategic position as a material for food and non-food production, besides that, cassava is also a foreign exchange earner through the export of flour, starch and other processed products. The research objective was to determine the effect of different custtings and slope modelson the growth and yield of cassava plants. The research uses local varieties from Tobelo in the hope that it can support the national cassava.  The study used a Divided Plot Design (RPT).  The main plot is the slope of the slope (M) which consists of three levels, namely: M1 (slope 0-3%), M2 (slope 3-8%) and M3 (slope 8-15%) and as a sub-plot is the cuttings model  L) which consists of three levels, namely: L1 (flat cuttings), L2 (one-sided tapered cuttings), and L3 (two-sided tapered cuttings. Parameters observed included plant height, number of leaves, stem diameter, leaf area,  tuber length, tuber diameter, weight of cassava per hectare The results showed that the treatment had no signify   cant effect either singly or in combination to the yield of cassava at harvest. The highest yield was found in the combination of M2L2 treatment, namely: 25 ton ha-1

Abstract

Land evaluation is the process of assessing land potential for various alternative uses. Land suitability evaluation is very flexible, depending on the needs of the area's conditions to be evaluated. Improvement efforts carried out on land will provide an overview of optimal land use in order to increase land productivity. This research aims to determine the level of land suitability for nutmeg plants in Luari Village, North Tobelo District, North Halmahera Regency. This research method uses a purposive sampling method, a type of sampling technique commonly used in scientific research. The main goal of purposive sampling is to produce a sample that can logistically be considered representative of the population. Identification of soil properties in the field is carried out using boring identification techniques, ring samples, and representative profiles. Soil sampling techniques are carried out using a disturbed and undisturbed method to analyze the physical and chemical properties of soil in the laboratory. Research results the actual suitability of land for nutmeg (Myristica. Fragrans Houtt) is divided into marginally suitable class (S3) covering an area of 167.8 Ha at SPL 01, 02, 03, 04, 05 and unsuitable class (N) covering an area of 37.3 Ha at SPL 06, 07, 08, with limiting factors in the marginal suitability class (S3) in the form of soil depth, lack of P2O5, N-Total, and slope, while the limiting factor in unsuitable land suitability (N) is slope.
