Harrow 3x2

Movable harrow bed with 2-disc storage guarantees perfect ground gadaption. By the gyroscopic effect of the tines triple coiling is a full-surface machining. The protected spring turn prevents pinching off the tips of plants.

Harrow 3x2

The six tine bar of harrow field will be matched with a lever or hydraulically to the required inclination. The aggressiveness and the tine pressure of the tines can be adjusted centrally at each harrow field (10 Settings), the aggressiveness of the tines of train (>90) to shock (

The Exact harrow can be used in conjunction with the RoTeC pro coulter system as well as the TwinTeC coulters. The Exact harrow tine has a thickness of 10 mm, is low-wearing and provides excellent seed coverage. The Exact following harrow serves for both coverage of the open seed furrows and for levelling. It operates, even where there are large amounts of surface straw, blockage free. With its individually pivoting harrow elements, the Exact harrow follows the undulations of the soil perfectly, ensuring an even seed coverage on soils either with or without straw.

The harrow pressure is adjusted mechanically by pre-tensioning the harrow springs. During hydraulic harrow pressure adjustment, a minimum and maximum value is predefined by inserting pins. So the harrow pressure and the coulter pressure can be simultaneously matched to changing soils via just one tractor spool valve whilst on the move.

Starting to love harrow delight! Quick to produce, easy to graft, taste is good for an early pear, disease resistant, productive as well! Why isnt every home orchardist growing this tree? Its unlikely i would be growing this pear now if not for the good advice and support of other long term forum members. This picture is of a 3 year old harrow delight grown without special care in a wet spot on callery rootstock in poor clay soil. These are grown spray free.

This is what they look like when they are ripe. I believe you do have a harrow delight but i did not find them fantastic the first year. Next year should be better for you. Mine were better this year. I think high sugar comes from growing in hot weather much of the time. Some things are location related. Hosui does not taste great here in my opinion but i have heard from others they love it at their location. Harrow delight should be more yellow when ripe.jpeg13801034 538 KB

The study was conducted in an area of expansion of sugarcane at Vale do Paraná factory in Suzanápolis city - São Paulo (SP), in Brazil, in the northwestern region of the State of São Paulo. It was used the sugarcane variety RB92-5345, 1.5m of spacing between rows, in an Ultisol. The study aimed to evaluate the productivity of sugarcane and first ratoon and some soil chemical attributes in function of soil tillage and application or not of gypsum. The experimental design was randomized blocks with six treatments, in a factorial 3x2 and six replicates, the main treatments were soil tillage with three equipments, moldboard plow, chisel plow, and heavy harrow, and two secondary treatments with application of 1 t ha-1of gypsum and no gypsum. After each harvest of cane, the soil was characterized as to its fertility indicators in layers of 0.0-0.15; 0.15-0.30 and 0.30-0.45m. Differences in values of soil chemical attributes due to the methods of preparation occurred in the sugarcane did not last until the harvest of the 1st ratoon cane, and also did not influence the crop productivity. The gypsum application resulted in higher values of total recoverable sugar (TRS) and the productivity of tons of stems per hectare (TSH) to sugarcane and 1st ratoon cane, respectively, confirming the initial hypothesis.

According to SALVADOR et al. (2010), to select the periodic tillage systems properly, we must take into account the energy demand and soil characteristics, such as texture and moisture. Greater knowledge and domains of these technologies may lead to reduced costs of crop production (KICHLER et al., 2007). Among the different soil preparation equipment, used in the culture of sugarcane, we may highlight the moldboard plows, harrows and chisel plow. Evaluating the energy requirement in different tillage systems based on plowing (disc and moldboard plow), harrowing (heavy and leveling) and scarification in Yellow Red Latosol, SALVADOR et al. (2008) found that scarification had lower energy demand when compared to other tillage systems studied. Evaluating different systems of tillage, MICHEL JUNIOR et al. (1985) achieved a reduction of up to 40% in energy requirement in scarification when compared to moldboard plow.

Due to the importance of these events in the implementation of the cane fields, and considering that the culture of sugarcane is deployed normally in depths between 0.25 and 0.35m, it is intuitive to think that the tillage with moldboard plows provide better conditions for the development of culture, but as the application of gypsum does not require incorporation, the hypothesis was released that different tillage systems have similar effects on the behavior of the culture, since the soil of the experiment showed no limiting compression. Another hypothesis is that, because it is a soil with low chemical fertility, the use of gypsum provides better conditions in the deeper layers and, thus, higher productivity. This study aimed to: verify the results of different methods of tillage (moldboard plow, heavy harrow and chisel plow), associated with the application or not of gypsum on the chemical attributes of an Ultisol and its effect in productivity and quality of sugarcane.

The experimental design was randomized blocks, in a 3x2 factorial design with six replications, totaling 36 plots. The treatments consisted of three methods of soil preparation: moldboard plow, chisel plow and heavy harrow, all followed by leveling harrow, and two treatments with 1t ha-1 with and without application of gypsum, for this treatment a corrective distributor cart was used equipped with belt feeder/metering with regulation and turntable.

Operations for deployment of treatments were as follows: distribution of dolomitic lime (2t ha-1) in total area (May 20th 2008); the main treatments (moldboard plow, chisel plow and heavy harrow) were implanted on June 3rd 2008, the average depth of tillage were 0.30, 0.26 and 0.25m, respectively; operation with leveling harrow in all treatments, and then secondary treatments were implanted with or without application of gypsum for casting on June 17th 2008, without incorporation.

The variety of sugarcane used was RB92-5354. The planting was done on June 25th 2008 in manual system, spaced 1.5 m between rows, averaging 15.5 buds m-1. In planting fertilization, we used 500kg of formula: 06-30-24, at planting, with an average depth of furrowing of 0.49, 0.48 and 0.46m for the moldboard plow, heavy harrow and chisel plow, respectively. In phytosanitary control, Fipronil was applied at a dose of 200g ha-1 (i.e.), in directed spray on stems in the planting furrow during the operation of furrowing cover. The weed control was carried out with application of diuron + hexazinone (702 + 264 g of i.e. ha-1) herbicides in post-emergence of the crop, and it was performed at 40 days after planting and for the 1st ratoon it was performed on January 4th 2010. On the same day, the fertilizer was applied in coverage of 1st ratoon cane, and 90kg ha-1 of N (urea) and 120kg ha-1 of K2O (potassium chloride) were applied and incorporated into the soil, with the aid of grower/fertilizer of two lines, carrying simple rods, in a distance of 0.20m, positioned on the top side of the planting row and at 0.20m deep.

In the 0.30 to 0.45m layer, the concentration of Mg2+ provided by chisel plow were lower than those obtained with moldboard plow and heavy harrow. However, in the treatment with gypsum, there was increase in contents of Ca2+ and S-SO4-2 and reduction of Al+3. The results presented here are corroborated by the theory of SOUZA AND LOBATO (2004), who said that, when the arable layer receives limestone and phosphate, the gypsum, to dissolve in water, will infiltrate in the soil, passing through this layer and getting trapped in the subsurface layers until 60 or 80cm. 041b061a72
