This research was conducted with the aim to find out the effect of the addition of potassium nitrate in lettuce as a medium and critical level of concentration(electrical conductivity)of nutrient solution. Research is organized in the form of a pot experiment. The experimental design used was Complete RandomizedBlock Design (CRBD)) with three replications. The treatment consists of 12 levels of concentrations or nutrient solution electrical conductivity with the addition of potassium nitrate to lettuce plant. The treatment level of concentrations (conductivity) of nutrient is as follows; L0 = 0.00; L1 = 1.25; L2 = 2.50; L3 = 3.75; L4 = 5.00; L5 = 6.25; L6 = 7.50; L7 = 8.75; L8 = 10.00; L9 = 11.25; L10 = 12.50 and L1 = 13, 75 g 100 L-1 water. Value concentrations of electrical conductivity each nutrient solution concentrations are: L0 = 0.06; L1 = 0.26; L2 = 0.46; L3 = 0.66; L4 = 0.86; L5 = 1.06; L6 = 1.26; L7 = 1,46; L8 = 1.66; L9 = 1,86; L10 = 2.06 and L1 = 2.26. dS m-1. The result of the experiment showed that addition of KNO3 highly significant effect on the increase in fresh weight and dry weight of shoot per plant. Fresh weight and oven-dry weight of shoot per plant was significantly increased in a quadratic with increasing concentrations of KNO3are optimum for growth of plant shoot weight were at 12.23 g in 100/of water on electrical conductivity equivalent to 2.01 dS.m-1. The addition of concentration of KNO3to nutrient solution does not affect on N and other nutrient solution on shoot tissue of lettuce plant but the concentrations of P and K in plant shoot tissue were significantly increased linearly with the provision of KNO3.

Soils are the main media for the growth of crops, the low yield of crops is always related to soil physical, chemical and biological soil conditions. Cattle manure is an organic fertilizer known well before chemical fertilizer. Many types of research on the use of cattle manure to ameliorate physical, chemical and biological soil properties have been conducted, but the optimum rates of cattle manure especially on sandy soil have never been found. This fact may be caused by leaching of organic materials and nutrients to deeper soil layer unreachable by roots. An experiment was conducted in a plastic house using sandy soils from the district of Kubu, Karangasem regency, with the objectives of studying the effects of rates of cattle manure on physical, chemical and biological properties f soils and the effects of inundated and water field capacity of soils on leaching of nutrients in the soils. The experiment was conducted from June until August 2010. The design used was a split-plot design consisted of four rates of cattle manure (0, 10, 20 and 30 t ha-1) as main plots and two water status of soils (inundated and water capacity) as subplots, with three replications. The results of the experiment indicated that cattle manure is able to ameliorate some of the soil physical properties as bulk densities (g cm-3), soil water status (%), soil permeability (cm hour-1) and total soil pores (%), and increased soil pH, C-organic content (%), C/N ratio, NPK and biological properties of soils of low nutrients status of sandy loam brown regosol soils derived from Vulcan intermediary. The results of the experiment also indicated the occurrence of leaching of organic materials and NPK nutrients to 20-40 cm layer. Based on the experiment results it is to suggest to the farmers that the use of cattle manure should be combined with synthetic chemical fertilizer in several applications during growth periods, but this required further researches.

This study was conducted in Balai Benih Induk (BBI) Luwus, Baturiti District, Tabanan Regency, with the high of place 506m above sea level occurring in March to May 2014. This research used randomized block design arranged per factor, namely population of plants (P) including three steps: P1=80.000 plants per hectare, P2= 100.00 plants per hectare, P3= 120.000 per hectare; and mulch (M) that include: M0= without mulch and without cleaning, M1= without mulch with clean weeding, M2= rice plants straw mulch (5 ton per hectare) and M3= black silver plastic mulch. Eventually, there were 12 combination treatments, each of which was repeated 3 times to obtain 36 land slots. The research indicates that there was no real interaction between the treatment of plant population and mulch usage in all variables observed. The 100.000 plant population per hectare can produce the weight of dry and fresh oven corn kernel without highest cornhusk that was to say 4.79 tons and 0.53 tons or 11.66 % and 20.45% higher compared to 120.000 plant population per hectare. The use of black silver plastic and rice plants straw mulch can produce the weight of fresh and dry oven corn kernel without cornhusk per hectare each of which is 4.69 tons, 4.57 tons, and 0.54 tons, 0.47 tons or 26.76%, 38.46 %, and 23.51 %, 20.51 % higher than without mulch and without clean weeding. Clean weeding treatment can produce the weight of fresh and dry oven corn kernel without cornhusk per hectare with its weight of 4.63 tons and 0.51 tons or 25.35 % and 35.90 % higher than without mulch and cleaning. Clean weeding treatment was not obviously different from mulch treatment. The identification of weed types were 19 kinds of weeds and Cyperus rotundus L. Weeds. They have the highest density and each absolute frequent of 1249.333 stems m-2 and 1.00.

This research has done in experiment garden of UNDANA , Faculty of agriculture from September 2010 to December 2010. The objective of this research is to find out the interval effect of giving indole butyric acid to the germination of papyrus (Borassus sundaicus Becc). This research used randomized complete experimental (RAL)with five treatments and four re-treatments, a parameter that has been observed involved longer of the root, diameter of the root, time of growth of root, a total of the root, length of root, time of growth of coleoptile and the dry weight of root. The result of this research conclude that the interval effect of giving the growth regulator of indole butyric acid (IBA) to the germination of papyrus in the average of the dry weight of root.where as the others observation variables are the longer average of a pool in the 2nd-week observation, 3rd-week observation, 4th-week observation, 5th-week observation, 6th-week observation and 8th-week observation have significantly effect.effect of treatments as a result of interval different is not unreal in the observation variables of longer of apokol in the 2nd-week observation and 7th-week observation, time of growth of root, total of root and time of growth of coleoptile.
