Abstract: Improving the farming productivity and profitability of sugarcane in Indonesia requires an appropriate fertilization method. So, three types of silicate rock-based fertilizers were developed and tested in field condition. The main objectives of this research were to identify the effects of liquid-silicate rock fertilizer (LSRF) in addition to NPK, and granules of NP70-Si and NP100-Si on the growth and yield components of sugarcane grown on Udipsamments. A randomized complete block design was employed with the treatment consisting of F-0 (NPK) as the reference of fertilizer package, F-1 (NPK + LSRF applied onto the leaf), F-2 (NPK + LSRF applied to the soil), F-3 (NP70-Si), and F-4 (NP100-Si), and those were replicated in five blocks. Results reveal that the applications of those different fertilizer packages significantly affected the germination of seed buds, cane production, and sugar yield, but did not for the other growth and yield components. The order of its agronomic and economic effectiveness of the fertilizer packages, based on the value of either cane production or sugar yield, was F-2 > F-1 > F-4 > F-0 > F-3. Therefore, the use of the fertilizer package of F-2 (NPK + LSRF) may be promoted as an appropriate fertilization method to improve the farming productivity and profitability of sugarcane in Indonesia.Abstract: Improving the farming productivity and profitability of sugarcane in Indonesia requires an appropriate fertilization method.

Abstract: Narbon vetch (Vicia narbonensis) is among vetch species adapted to highlands of Bale. It is semi-erect to erect vetch with striking similar to faba bean. Seed rate and row spacing are among the most important factors affecting dry matter and seed yield of any crops. However, optimum seed rate and row spacing were not determined for narbon vetch under conditions of Bale high lands. Therefore, the experiment was conducted from 2014-2017 on research field of Sinana Agricultural Research Center, Sinana on-farm and Agarfa research subsite with the objective of determining optimum seed rate and row spacing for yield and yield components of narbon vetch under conditions of Bale highlands. Narbon vetch variety ‘Abdeta’ that was released from Sinana Agricultural Research Center in 2011 was used as a test crop for this experiment. The treatments consisted of three row spacing intervals (20 cm, 30 cm and 40 cm) and six seed rate levels (30 Kg/ha, 45 Kg/ha, 60 kg/ha, 75 Kg/ha, 90 Kg/ha and 105 Kg/ha) laid out in factorial combination of randomized complete block design (RCBD) replicated three times. The analysis of variance showed that seed rate and row spacing had a significant effect on yield and yield components of narbon vetch. The highest seed yield (43.22 qt/ha) was obtained from narbon vetch planted at a seed rate level of 60 kg/ha. Row spacing of 20 cm had also leaded to highest seed and dry matter yield. Based on the current study it was concluded that narbon vetch can be produced at a seed rate of 60 kg/ha and 20 cm row spacing in high lands of Bale and similar agro-ecologies.Abstract: Narbon vetch (Vicia narbonensis) is among vetch species adapted to highlands of Bale.
