The factors that influence rubber production are planted clones, plant care and tapping techniques. With the right tapping technique, both tapping time, tapping method and mature tapping age, the production potential of a superior clone of rubber plants that has been well maintained can be maintained. The technique of rubber tapping is closely related to the expected level of production, even very determining the age of the tree economy. The research objective was to determine the effect of stimulant better and tapping time on latex production. The method used was a randomized block design with two-factor split plot design. The first factor (main plot) is the time of tapping consists of 3 levels, namely; w1: 05 in the morning, w2: 06 in the morning, w3: 07 in the morning. The second factor (sub-plot), namely the stimulant dosage better consists of 4 levels, namely; b0: control, b1; 0.5 g, b2; : 1 g, b3; 1.5 g. The results showed that stimulate better treatment had a significant effect on latex volume, wet weight and latex dry weight, but was not significant for latex dryness levels. Tapping time was not significant for latex yield, latex volume, wet weight, latex dry weight and highest dry rubber content at 7am. Stimulant Better treatment has a significant effect on latex volume, wet weight, and latex dry weight, but if given at high doses it will reduce the dry content of rubber. The interaction of treatment when tapping and stimulant is better not significant for latex production. The stimulant application better does not exceed the dose of 0.5 g / principal. Doses> 0.5 g / staple will have an impact on the dry tapping field.

The effect of the nitrification inhibitor 3,4-dimethylphyrazole phosphate (DMPP) on N-fertilized crop growth and soil N<sub>2</sub>O emissions were studied at two experimental sites in Southern Italy, characterised by a Mediterranean climate and different soil texture. The experiments were a randomized block design of two treatments: crop fertilized with NH<sub>4</sub>NO<sub>3</sub> (considered the control treatment) or amended with DMPP plus NH<sub>4</sub>NO<sub>3</sub> (considered the DMPP treatment). ANOVA was performed to assess differences between treatments and fertilization periods whereas simple and multiple linear regressions were performed in order to assess the effect of the soil-related in-dependent variables on soil gases emissions. Growth of potato plants fertilized with DMPP-added nitrogen was enhanced compared to control plants, whereas no benefit on maize plants grown during summer was observed. N<sub>2</sub>O emissions measured from soil to potato after the first fertilization with DMPP-added nitrogen was reduced during winter, but was higher than control after the second fertilizer application in spring, leading to comparable N<sub>2</sub>O emission factors (EF1) between treatments. In maize N<sub>2</sub>O emissions and EF1 were lower for DMPP compared to control treatment. The effectiveness of reduction in soil N<sub>2</sub>O emission was influenced by soil temperature and water-filled pore space (WFPS) in both experimental sites. However, the overall effect of WFPS was contrasting as N<sub>2</sub>O emissions were decreased in potato and enhanced in maize.
