Rotavator: Rotavator carries out secondary tillage operations such as harrowing and leveling in single operation. It destroys weeds, incorporates manures/fertilizers and left-over stubble of previous crop, brake down larger clods and pulverizes the soil. It prepares seed bed in one pass thus saves draft power, time, labour and cost as compared to conventional tillage. Rotavator can play an important role in intensively cultivated regions where window period for seed bed preparation is very narrow. Continuous use of rotavator may create subsoil compaction just beneath the operational depth, causing accumulations of water under excessive rain. It reduces land preparation cost by ₹ 1000-1500 per ha as compared to traditional method.

Laser land leveler: Field with undulating topography suffers from uneven crop stand due to uneven seed placement depth and uneven distribution of moisture. It also leads to runoff and erosion, and non-uniform maturity of crops. Uneven field needs higher energy and cost in field preparation. Excess soil moisture at lower elevation causes water logging and leaching, whereas moisture deficit at higher elevation limits water and nutrients uptake. Thus, land leveling is pre-requisite for getting higher resource use-efficiency. Laser land leveler provides a very precise land leveling and results more uniform moisture environment and crop stand. It also save costly agri-inputs (seed, fertilizer, irrigation etc.). Runoff from field applied/rain water along with applied agro-chemicals also minimized, addressing environmental issues.

Ridge planter: Maize is very sensitive water logging. Drought also causes substantial yield loss to the crop. Bed planting saves the crop in extreme water conditions like excess or deficit rainfall. During excess rainfall the furrow act as drainage channel while it stores rain water during low rain events. Ridge planters are commercially available which can do bed making & sowing on the tip of the bed in a single operation. Ridge planting ensure better root development, lesser logging, saving of irrigation water and also cut down operational cost. It can cut down 24 and 90 % cost and time, respectively when compared with conventional method.

Zero till planter: In conventional agriculture, one ploughing, 2-3 harrowing followed by planking is done for good seedbed preparation and weed control. These 4-5 runs of tractors and tractor attached heavy tools, press the soil particles affecting soil structure, and create compaction problem which hinder seedling emergence, root penetration, soil aeration and water movement. Further, these conventional tillage operation needs excessive fuel, larger turn around period and labor enhancing cost of cultivation. Alternative to conventional tillage is no-till planting, under which planting is done in stubble of previous crop without any soil disturbance/tillage operation. This technology reduces capital investment in land preparation and intercultural operations. It is a viable replacement of conventional and tillage-intensive agriculture. This technology is very common in the U.S.A, Canada, Argentina and Australia. In India zero till maize planting has been adopted in coastal Andhra Pradesh in rice-maize system. This technology saves diesel, tractor’s working time and labor enabling timely sowing of crops. If zero planting is combined with residue mulching, it modifies hydro-thermal properties and protect the crop during adverse conditions.
