Table 4. Statistical interpretation yields obtained by analysis of variance (ANOVA test) The results were summarized in figure 3, where it can observe a fluctuating evolution of the weight of thousand grains (MMB) and weight of hectoliter graine (MH) indices for experimental variants, variants that low for a1b1c3; a1b2c3; a2b1c3 and a2b2c3, on both soil types for both varieties in unfertilized sole. In contrast, the highest values of quality indices of production variants were obtained a1b1c2, a1b2c2, a2b1c2 and a2b2c2, experimental variants placed on both soil types, with both varieties of barley studied fertilized with DOE (optimal economic dose). Figure 3. Graphic with indices of quality for experimental variants Figure 2. Yield differences recorded for each experimental variant, compared to the control (average yield) The results of laboratory analysis about quality index of yield for each experimental variant were summarized in Table 5. Table 5. The results of quality index of yields Economic efficiency was calculated using the difference between incomes and expenses recorded per hectare for each combination of experimental factors. For this, we used technological currency, first by calculating the mechanical work expenses and materials used for each experimental variant and the proceeds according to the production recorded each variant was calculated profit per hectare. The results of comparative economic efficiency recorded in the two years of the study were summarized in Figure 4. Comparing the results obtained with the control (mean variants), it has been observed that the biggest profit was recorded version a1b2c2 with a difference compared to control 664 lei/ha in 2010 and 457 lei/ha in 2011, followed in descending order of variants a1b2c1 and a1b1c2. The lowest results on the yield compared to the control were recorded by a2b1c3 variant, which is Cardinal variety, cultivated on Solonetz and unfertilized (with a difference-98 lei/ha in 2010 and-10 lei/ha in 2011) followed by a1b2c3 variant, which is Marshal variety grown on chernozem unfertilized (with a difference-97 lei/ha in 2010-46 lei/ha in 2011). 371
Figure 4. Chart of economic efficiency achieved by each experimental variant, compared with the control (average of variants) CONCLUSIONS Because of the agricultural use, there is a continuous decrease in soil nutrient content, so the study of the influence of soil type and fertilization doses are required for any crop. a1b1c2, a1b2c2, a2b1c2 and a2b2c2 experimental variants, that means both varieties grown in both soil and fertilized with economic optimum dose for Solonetz have obtained very significant positive differences compared to the control (average of experience) in both experimental years, both on the quantitative and quality indicators on production. Very significant negative differences compared to the control were obtained by a1b1c3, a1b2c3, a2b1c3 and a2b2c3 variants, respectively both varieties of barley grown on two soil types fertilized in both experimental years for quantitative and qualitative indices. In terms of economic efficiency, the highest profit was recorded by a1b2c2 variant, which is Maresal variety grown on chernozem, fertilized with optimum dose for Solonetz followed in descending order of a1b2c1 variant (Maresal variety cultivated on chernozem, fertilized with optimal dose for chernozem) and a1b1c2 variant (Cardinal variety cultivated on chernozem, fertilized with optimum dose for Solonetz). The lowest economical efficiency was recorded by a2b1c3 variant (Cardinal variety cultivated Solonetz, unfertilized) and a1b2c3 variant (Maresal variety cultivated on chernozem unfertilized), which shows that doses of fertilization influences a greater increase production and economic efficiency than soil type.
