Abstract

This research aims to determine the type of best plants vine of the long pepper as cuttings material and to determine the effectiveness of cow urine fertilizer in improving growth of cuttings. Research conducted during the dry season 2008 in the Demangan village Bangkalan district with 20-50 m height above sea level (asl), 25-33oC temperature and soil pH 5,5-6,5. Research designed factorial, consisting of 2 factors and 3 times replications using Random Design Group. The first factor is the type of vine cuttings consisting of: soil vine cutting (S1), climbing vine cuttings (S2), fruit vine cutting (S3) and the second factor is the application of cow urine fertilizer consisting of: no cow's urine (P0) , fresh cow's urine (P1), cow urine was fermented with EM4 (P2) each with a dose of 2 ml/20 ml water / plant given every 2 weeks until the cuttings was 12 weeks after planting (MST). The observed parameters include the bud emerge, amount of leaves and leaf area of plants, amount of roots and total plant dry weight. The results showed that there are interactions between the 2 factors tested against the number of roots and total plant dry weight, leaf area parameters are influenced only byvine cuttings type while the bud emerge andamount of leaves was not influenced by either factor. Climbing vine cuttings is the best type of long pepper vine because it has the highest leaf area, amount of roots and total dry weight. Cow urine fertilizer giving positive effect on the growth of cuttings, which fermented cow urine have better effect than fresh cow urine.

Abstract

Coffee is the second priority and is nationally leading commodity aimed to increase export  as well as  to improve added values of national production in order to gain high compatibility in the international level. The development of coffee plantation in Indonesia focuses on the increased proportion of arabica coffee. The technology offered is to establish the superior characteristics of robusta coffee (lowland habitats) and that of arabica coffee (highland habitats) into a single crop named robbica cofffee. The idiotype of arabica crops has not been studied at the low and moderate altitude of land.            The study uses a randomized block design arranged at a split-plot, where two altitude act as the main-plot (10 m and 500 m above sea level) and ten genotypes of arabica coffee as the sub-plot (five genotypes of arabica and five genotypes of robbica), with three replicates and four crops for each experimental unit. The sample crops are located  at the centre of the plot (two crops for each experimental unit). Variables observed are plant height (cm), stem diameter (mm), are of a couple of leaf (cm2), weight of a couple of leaf (gram), the number of stomata, the level of leaf greeness, the content of leaf chlorophile (A and B), and nitrate reductase activity.            Result of variance analysis showed that genotypes significantly affect plant height, stem diameter, area of a couple of leaf, weight of a couple of leaf, and the number of stomata. The level of leaf greeness, and the number of chlorophile (A and B) show insignificant responses genotypes. The study conclude that the idiotype of arabica coffee, i.e. that is having a combination of robusta and arabica performs better than pure arabica, the habitat of moderate altitude is more favourable than that lowland, and the cultivation of arabica at the moderate altitude requires a modification of enviroment by plantibg the shade plant from leguminosae family.
