Digging Efficiency

This study aimed to evaluate the root crop digger for digging of the potato crop at the farmer’s field. The digger was tested at three levels of forward speeds (2.3, 2.8 and 3.3 kmh-1) and three levels of rake angles (170, 200, and 230). The experiment was replicated three times for the performance parameters of exposed,undug, cut, bruised percentage and the digging efficiency. The best performance of the digger was obtained at forward speed 2.3 km h-1 and blade angle 230 for potato crop at which the exposed, undug, cut, bruised percentage and the digging efficiency was found to be 90.62,2.10, 1.71, 2.48 and 97.90 per cent, respectively. About 54% savings in cost of digging could be achieved using digger compared to manual digging involving labour.

Optimization Of Variables

In India, most of root crop is harvested manually and it consumes high labour and time for harvesting. The optimization of a tractor operated digger was evaluated at farmer’s field for the carrot crop. The digger was optimized for forward speeds of 2.2, 2.7 and 3.2 km h-1 and the rake angles of blade as 170, 200 and 230. The parameters viz., digging efficiency, undug, cut, bruised and exposed percentage was optimized as per the experiment. The performance of the digger was found to be best at a speed of 2.2 km/ hr and blade angle of 23 degree with a The digging efficiency, cut percentage, exposed percentage and bruised percentage of carrot crop was found to be 100 , 46.2, 92.12 and 28 %, respectively. The capacity of the machine was 0.18 ha/h. The break-even point for digger was 35.14 hour per year. The payback period of digger was 0.24 year.

The profitability of ex-situ straw management largely depends on the quantity and quality of straw recovered from the field. The straw reaper-combine is one of the widely used ex-situ straw management technologies being used to retrieve the leftover residue in the field after grain combine operation. Besides considering the positive implication of this technology in recent times, the quality of operation, which accounts for maximizing the performance parameters of straw reaper-combine in a wheat crop. The relationship among these parameters was established using multiple linear regression techniques through the regression equation. The ANOVA test of this experiment also established the significant (P<0.01) effect of forwarding speed and cutting height on all performance parameters. It was observed from the experiment that when the forward speed was increased while keeping the cutting height at a constant level the recovery percentage and specific energy consumption were decreased whereas, straw split percentage and actual field capacity were increased. Likewise, when cutting height was increased keeping the forward speed at a constant level the recovery and split percentage were reduced but, the actual field capacity and specific energy consumption were increased. In order to achieve maximum performance at optimum energy consumption, the straw reaper should be operated at a speed between 3-4 km/h with cutting height between 30-60 mm.

Digging Efficiency

The ginger (Zingiber officinale) rhizome is harvested manually by different types of spade, fork or bullock drawn plow. These methods consume more time, cause drudgery, losses and low field capacity. Therefore a tractor drawn digger was evaluated for ginger crop. The performance parameters (exposed, cut, bruised and digging efficiency) of the digger were studied at 3 forward speeds and 3 blade angles. The performance of the digger was found satisfactory in respect of digging efficiency of 98.01%, and undug crop of 2.38 % at an average depth of operation of 15.75 cm. The damage was 1.98 per cent which was much low as compared to manual digging of ginger crop (9.73%). The machine takes 7.4 hours to dig one-hectare area of ginger crop with field efficiency of 87.82%.

Research highlights the importance of potato crop, which occupies a prominent food and economic status in food security besides rice, wheat and corn at the local and global level. Despite the expansion of the cultivation of potato crop in Iraq in general and Ameriyah district in particular However, potato productivity remains substandard, this may be due to a lack of knowledge of the most efficient varieties and not to use productive resources at the levels at which technical, specialized and economic efficiency is achieved. Therefore, the aim of the research is to determine the technical, specialized and economic efficiency according to the cultivated seed category. The data envelope analysis (DEA) method was used to estimate technical, specialized and economic efficiency, assuming constant and variable capacity returns. As a result of the study, the Safrana variety achieved the highest average technical efficiency according to the stability of the yield and capacity efficiency in addition to achieving the highest average specialized and economic efficiency, The Lapadia variety achieved the highest average technical efficiency, assuming that capacity returns have changed. Therefore, we recommend the adoption of items that achieve higher efficiency and the need to redistribute the elements of production better and Achieving the optimum levels at which technical, specialized and economic efficiency is achieved and saving what has been wasted.

A field experiment was carried out in the field of the College of Agriculture / University of Wasit, located on longitude  45o   50o   33.5o   East and latitude 32o 29o 49.8o North, in Spring season of the agricultural season 2019, in order to estimate the water consumption of potato crop using SWRT technology and under the drip irrigation system. The experiment was designed according to Randomized Complete Block Design (RCBD) with three replications and four treatments that include of the SWRT treatment (the use of plastic films under the plant root area in an engineering style), and the treatment of vegetal fertilizer (using Petmos), organic fertilizer (sheep manure), and the control treatment . Potato tubers (Solanum tuberosum L.)  var. Burin was planted for spring season on 10/2/2019 at the soil depth of 5-10 cm. The highest reference water consumption for the potato crop during the season was calculated by Najeeb Kharufa, which was 663.03 mm. The highest actual water consumption for the potato crop during the season for the control treatment was 410.1 mm. The results showed increase in the values of the crop coefficient (Kc) in the stages of tubers formation and tubers filling stage as compared to the vegetative and ripening stages, ranged from 1.37-1.92 for the two stages of tubers formation and tubers filling. The SWRT treatment gave the highest water use efficiency during the season, was 3.46 kg m-3 .
