Two different methods for determining irrigation water requirement for corn, is KP-01 and Thornthwaite-Mather method. Two Methods have different parameter such as reference crop evapotranspiration (ETo) and effective rainfall. The average ETo value using Penman-Monteith for Thornthwaite-Mather was lower (82,5%) than using Penman Modification method (KP-01) . The ratio of effective rainfall between KP-01 and Thornthwaite-Mather was 33,02%. Corn water irrigation requirement for a pattern planting based on KP-01 is 806,96 mm, while corn water irrigation requirement based on Thornthwaite-Mather method is 254,4125 mm. Corn water irrigation requirement using KP-01 is higher than Thornthwaite-Mather because effective rainfall method for KP-01 (using USDA Soil Conservation Service) is lower than rainfall effective for Thornthwaite-Mather.

Spodoptera litura F. is one of the important pests in Horticulture commodities which can cause damage 80% and up to 100%. Karamunting (Melastome malabathricum) is a wild plant that grows in Tarakan City. This plant is known to contain secondary metabolites which are thought to have the potential to control pests. This study aims to determine the potential of Karamunting extract as a botanical insecticide material to control armyworms. This study uses a completely randomized design (CRD) method with 1 treatment factor, namely the concentration of Karamunting leaf extract. Potential extracts as botanical insecticides were tested by dye method using 4 concentrations, namely 0 (control); 500; 1000; 2000; 4000; and 8000 ppm. The results showed that Karamunting leaf extract was able to control armyworm pests. Giving extracts of 8000 ppm (P5) in feed caused the highest decrease in eating activity up to 41,2%, larval mortality up to 85%, and the highest mortality rate after 7 days of observation. Decreased feeding activity and larval mortality were thought to be influenced by the presence of phenol compounds, fatty acids, terpenoids, sterols and alkaloids identified in the extract. Thus, Karamunting leaf extract has the potential to be developed as an active ingredient in botanical insecticides to control armyworm.

This study aims to determine the response of growth and production of shallot (Allium cepa L.) to the Nitrogen fertilizer and Granule Organic fertilizer. The design used was a Factorial Completely Randomized Design consisting with two (2) treatment factors. The first factor is Nitrogen (N) from Urea which consists of three levels, namely: N1 = 2 g / plot, N2 = 4 g / plot and N3 = 6 g / plot. The second factor of Organic Granule fertilizer consisted of three levels, namely: G1 = 5 kg / plot, G2 = 10 kg / plot, G3 = 15 kg / plot. The results showed that interaction of Nitrogen fertilizer and Granul Organic fertilizer significantly affected plant height, number of leaves, number of tillers and tubers wet weight per plot, but not significant for the number of flower stalks. The highest growth and production of shallots produced a combination of treatment N3 = 6 g / plot and G3 = 15 kg / plot.

Organic matter contained in manure fertilizer function to improve soil physical properties, soil chemistry, and soil biology. Local microorganisms from banana weevils contained macro, micro nutrients and contained bacteria which will act as decomposers of organic matter.This research aimed to determine the effect of the combination of manure fertilizer and local microorganisms on the growth and yield of lettuce. The research was conducted on the land of the Faculty of Agriculture, Methodist University, Medan, in March - April 2016, using split plot design, with three replications, 9 combinations to obtain 27 plant plots of all combinations and replications was used in this study. The first factor tested was manure fertilization ie R1= given chicken manure 45 g plant-1, R2 = given cow manure 45 g plant-1 and R3= given goat manure 45 g plant-1. The second factor tested was local microorganisms that was D1 = 30 cc l-1 water), D2 = 40 cc l-1 water and D3= 50 cc l-1 water. The results showed that the treatment of types of manure and local microorganisms in general had a significant effect on the growth and production of lettuce plants. The provision of chicken manure as much as 45g plant-1 (R1) and local microorganisms 50 cc l-1 water (D3) gave a better response to the growth of plant height, number of leaves, amount of chlorophyll and wet lettuce better than other treatments.
