| The objective of this study was to evaluate potato plant growth and macronutrient uptake, as affected by soil tillage methods, in sprinkle and drip irrigated experiments. Eight treatments were set: T1, no tillage, except for furrowing before planting; T2, one subsoiling (SS); T3, twice rotary hoeing (RH); T4, one disc plowing (DP) + twice disc harrow leveling (DL); T5, 1DP + 2DL + 1RH; T6, 1DP + 2DL + 2RH; T7, 1SS + T6; T8, one moldboard plowing (MP) + 2DL. Treatments were arranged in a randomized block design with four replications. In both irrigation systems, plants presented higher emergence velocity index (EVI), when the soil was not tillaged, and the EVI was inversely related to the maximum tuber dry mass production. In both experiments, a functional... |

| The adoption of appropriate cultural management, which includes nitrogen fertilization and soil tillage system, is very important to increase the efficiency of plant in the utilization of available resource. This research work was conducted for three years aiming at evaluating the effect of sidedressing nitrogen application (0, 25, 50, 75, and 100 kg ha-1) on winter bean crop under different systems of soil management (conventional, minimal, and no-tillage systems). The experimental design was a randomized block arranged in strips relative to tillage systems, with random distribution of nitrogen doses into each strip, with four replications. Grain yield was affected by nitrogen rates and significant increases were obtained with the application of 75 to 100... |

| The use of sprinkler irrigation for rice (Oryza sativa L.) crop is a relatively recent practice in Brazil. Therefore, crop soil and fertilization management are still not very well defined. Another problem is the inexistence of specific cultivars adapted to this cropping system. This study aimed to evaluate sprinkler-irrigated upland rice cultivars under different soil management practices and nitrogen sidedressing rates in relation to yield and grain quality. A randomized block design was used, arranged as a 3 x 3 x 5 factorial scheme, totaling 45 treatments consisting of the combination of three rice cultivars (Primavera, Confiança and Maravilha), three soil management systems (disk harrow + levelling harrow, moldboard plow + levelling harrow and... |

| In most small holder farmers in Ethiopian highlands, farmers still use the wooden ard plow (Maresha).The present trial was conducted in 2011-2012 at Gumara Maksegint water shade, to evaluate the effect of four different tillage methods on teff and wheat yield and soil physical properties. The experiment was performed using a randomized complete block design with four treatments and three replications. The experiment was carried out on two soil types, a sandy Nitosol prevailing in the hilly upper areas and clayey Vertisol prevailing the valleys. Land preparation by tillage was done with either a Moldboard plow, Gavin plow, or traditional plow, and was compared against a No-tillage treatment. Animal draft force, soil bulk density, penetration resistance,... |
