Deep tillage in dry land is a draft intensive operation and on the other hand, draft requirement of multi-powered tools is lower than that of the passive tools of similar capacity. Hence it was proposed to investigate about an Oscillatory Tillage Implement for primary tillage which can be driven by its own eccentric drive in dry land. An Oscillatory Tillage Implement was developed and the tools were arranged in two rows and crank was located at the middle of the two rows of the tillage tools. The connecting rods were used to connect the crank and tillage tools. The crankshaft will be driven...

Fertilizer is costlier input in agriculture hence suitable type of fertilizer and its efficient use is essential. The liquid fertilizer available in the market are 5 to 6 times costlier than conventional straight fertilizer so attempts needs to be made to explore possibility of using water-soluble straight fertilizer for crop through drip. It is also essential to study the effect of varying levels of fertilizer on crop growth and nutrient uptake under fertigation and planning of efficient fertigation schedule depending on its growth stages. For uniform and efficient application of water and...
