Abstract

Cassava is one of the local food sources that are widely available in almost every region. Cuttings are used to plant cassava, and these cuttings will produce a number of roots and buds. The main purpose of this study was to evaluate the effect of cuttings slices model and the number of buds on the growth of Tobelo local varieties of cassava. This study employed a factorial Randomized Block Design (RBD), with the cuttings slices model as the first factor, consisting of three levels, namely: flat slice, one-sided slice and two-sided slice. The second factor is the number of buds, which is divided into three levels, 1 bud, 2 buds and 3 buds. The observation parameters in this study include plant height, number of leaves, stem diameter and leaf area. The results have revealed that the model of two-sided sliced cuttings combined with the number of one bud is the most effective treatment in improving the growth of cassava plants of Tobelo local varieties. The models of one-sided and two-sided oblique cuttings slices yield the highest average value for the parameters of plant height, stem diameter and leaf area, while the treatment with one bud tends to give the best results for the growth parameters.

Abstract

This study aims to determine land suitability class for of plantation crops, namely, coconut, clove, and cocoa in Galela region, North Halmahera, North Maluku. The determination of land suitability is determined by using the comparison method between the quality of the land on the condition of plant growth, the criteria using two methods, namely Simple Limitation Method (SLM) and Sys Criteria. The result showed the actual land suitability for coconut and clove using SLM system was obtained into two classes, S3 (marginally suitable) and N (unsuitable); whereas the potential land suitability was obtained into three classes i.e S2 (moderately suitable), S3 and N, for cocoa the actual and potential land suitability was obtained into classes N. While,  according to Sys Criteria, the actual land suitability for coconut and clove the obtained two classes i.e. S2 and S3, the potential land suitability for coconut into three classes i.e S1 (very suitable), S2, and S3, for clove into two classes S2, and S3, while for cocoa the actual and potential land suitability was obtained into classes S3. The generally, limiting factors in the cultivation of plantation crops in Galela region, North Halmahera, North Maluku include rooting media, nutrient retention, nutrient availability, erosion hazard, drainage, sodicity, and water availability. The supply of volcanic ash material from Mt. Dokuno positively affect the growth of plantation crops in Galela region. The approach method with Sys Criteria is well suited to determine the suitability of plantation land in the Galela region.
