Abstract

This research aims to find out the effectiveness of Neem and the application of Nitrogen to nitrogen leaching and sweet corn growth on peat soil. This research has been conducted in gauze house of Technical Implementation Unit (TIU) experimental station and analysis of leachate water has been conducted in Laboratory of Soil Science, Faculty of Agriculture, University of Riau, Pekanbaru. The research was held from October 2014 until January 2015. This research is factorial experiment and prepared in Completely Randomized Design (CRD) that consisted of 2 factors, which are nitrogen (N) application which is without nitrogen and with nitrogen 3,75g/column, and the second factor is Neem (M), which is without neem, 0,37g/column, 0,56g/column, 0,75g/column. The data that were obtained from research results were analyze statistically by analysis of variance (ANOVA). The result of ANOVA further were tested using Duncan’s multiple range test 5% significant level. The results of this research show that the application of neem until 0,75g/column dosage is not effective in decreasing nitrogen leaching on peat soil. The application of nitrogen on peat soil increases ammonium on leachate water on fourth week, but not on second and sixth week, while, on nitrat of leachate is significantly different compare to without application of nitrogen. The application of neem until 0,75g/column dosage and nitrogen 3,75g/column does not increase the growth of plant.   Keywords : Neem, Nitrogen, Nitrogen leaching, Sweet corn, Peat soil

Abstract

Research on effects of some dose of palm oil mill effluentand media on the growth of oil palm Seedlings( Elaeisguineensis Jacq .) fase main nursery, plantation experiment have been conducted in garden experiment of the Agriculture Faculty, Riau University was startedon march  until june 2015. with the aim to get the dose of palm oil mill effluent and media works best for seedlings growth palm oil. A field experiment was conducted by using split plot design, in which three levels of media ie; Ultisol ,Histosol , and mixure, were assigned to main plot and four levels of palm oil mill effluentie; control , 0.8 l , 1.6 l , and 2.4 l. The Parameters observed were plant height, leavesnumber, the increase in diameter stump,root volume, root crown ratio, dry seedling weight.Based on research results that palm oil mill effluent 2.4 l in a media mixure show results in best than other treatment to increase plant height,diameter stump, root crown ratioon palm oil in  main nursery.   Keywords :palm oil mill effluent, media, oil palm Seedlings

Abstract

This study aims to determine the effects of chicken manure and coconut water fertilizer on the growth and production of green bean plants (Vigna radiata L.) in alluvial soil. The design of this experiment was Completely Randomized Design (CRD) which consist of 2 factors; The dose of chicken manure (A) and consisting of four levels: (A0) without the dose of chicken manure, (A1) Chicken manure dose of 15 tons.ha-1 (60 g.polybag-1), (A2) Chicken manure with dose of 17.5 tons.ha-1 (70 g.polybag-1), (A3) Chicken manure dose of 20 tons.ha-1 (80 g.polybag-1) and; Coconut water concentration (K) which consist of three levels, i.e: (K1) coconut water concentration of 50%, (K2) coconut water concentration of 75%, and (K3) coconut water concentration of 100%. The parameters observed were plant height, flowers age, hervest age, the number of root nodules per plant, number of seeds per pod, total number of pods per plant, and weight of 100 dried seeds. The result of this experiment that the dose of chicken manure and coconut water gave no significant effect on the growth and production of green bean plants (Vigna radiata L.) in alluvial soils. Key Words:Green Bean, Dose of Chicken Manure, Coconut Water.
