Scope and Importance
To prepare a good seed bed with good soil tilth is necessary for getting good crop yield. The preparation of wheat fields after harvesting the paddy crop is quite difficult in heavy soils. Due to crack development in the soil, the conventional implement. do not work properly as there is tendency of lifting of big clods and the upper layer of the soil is not always loosened to the desired extent, nor is the proper mixing of different layers achieved. Frequent operation with the conventional implement must performed for the preparation of seedbed for the sowing of wheat crop. In addition, the stubble of rice crop creates problems especially when the crop is harvested with the combine harvester. It requires high amount of energy input (20-30%) for tillage operation.
The tractor operated rotavator is quite effective to prepare seed bed in dry as well as wet conditions. The rotary tiller prepares well puddle soil which reduces basic infiltration rate of water. To obtain specific benefits of early seed bed preparation soon after harvesting of paddy crop for sowing wheat and after harvest of wheat crop for sowing of paddy. This will not only require low energy in tillage operation but also mix and incorporate the stubbles of previous crop thoroughly in the soil. This will improve the soil health and save environment since burning of left over straw is not required.
The Main features of rotavator are: Saves water, time, energy, labor and money, Level of field not disturbed and used throughout the year, No injury to finger during transplanting when field is prepared with rotavator, Boron steel blades that last 50% more than hi carbon. Available in “L, J & C” type blades, Heavy duty PTO with shear bolt, Easy depth adjustment
The perfect levelling in surface irrigation save amount of irrigation water resulting in uniform crop stand and yield. It can be achieved only by using laser guided land leveler. Laser is a device that produce a very concentrated beam of light, which is single, very thin, high energy beam. A rotating laser light source (like a miniature lighthouse) is located somewhere in the field. As the laser rotates rapidly, a virtual "plane" of light is produced in the field. If the earthmover climbs over a high spot in the field, the blade will dig in as the receiver tries to stay locked on to the laser source.
If the earthmover goes over a low spot, the blade will lift, again keeping locked onto the laser source, and dump soil into the low spot. If the rotating source is tilted as per prescribed grade, a grade can be installed in the field. The control panel mounted on the tractor interprets the signal from the receiver and opens or closes the hydraulic control valve, which will raise or lower the bucket.
The Main features of tractor operated laser guided land leveler are: Save seed and fertilizer, reduces the amount of water required for land preparation, reduces weed problem, uniform moisture available for crops resulting in maturity and uniform yield,
