Abstract

The research was conducted to result F factor value (fraction of available water that could be absorbed by Kaempferia galangal L.). This value was needed for determining irrigation frequency.  Factorial experiment was arranged in Randomized Block Design with three replications.  The first factor was irrigation frequency included irrigation until field capacity every 2, 4, 6, 8 days respectively, irrigation every 2 days until 75%, 50%, and 25% of available water respectively.  The second factor was irrigation time included from planting, 2 weeks before harvesting, and 4 weeks before harvesting until harvesting respectively. Interaction between irrigation frequency and irrigation time effected plant height, leaf area index, evapotranspiration, but did not affect yield.  Treatment that resulted the highest plant, the biggest leaf area index and the least evapotranspiration was irrigation until field capacity every 6 days from 4 weeks before harvesting until harvesting. The research resulted F factor value (fraction of available water that could be absorbed by Kaempferia galangal L.) as much as 48%.

Abstract

Productivity improvement of physic nut can be done by the increase of female flowers numbers. Introducing of plant growth regulators (PGR )is one of many ways to stimulate flowering. The research was aimed to determine the dose of plant growth regulators NAA (Naphthalene Acetic Acid) which can increase the level of production and oil contents. This research was conducted at the Asembagus Experimental for 12 months. Five doses of 500, 1000, 1500, 2000, and 2500 ppm NAA were applied on two years old of J. curcas and arranged in a randomized block design with three replications. For comparison, treatment without PGR was added in treatments. The results showed that NAA application affected the growth plant height, canopy diameter and number of branches and production of fruit numbers, 100-seed weight and oil contents of jatropha. PGR application was able to increase the number of fruit and weight of 100-seed each for 26.64 and 2.07%, respectively, and to reduce the oil contents of 3.05% untreated PGR. Dose of 1000 ppm NAA was able to increase the fruit number and weight of 100-seed each for 35.09 and 2.99%, respectively and reduce the oil contents of 3.58%.

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.
