Sorghum is the most important cereal crop of Scarcity zone of Maharashtra. The area of sorghum
in Maharashtra is about 19.35 lakh hectare with a production of 31.62 lakh tones and
productivity of 912 kg ha -1 . Productivity of sorghum is decreasing continuously due to use of
imbalanced chemical fertilizers accompanied by restricted use of organic manures as well as may
be due to intensive cultivation of sorghum under medium deep black soils. Vertisols are selfpulverized
soils and hence need not require special tillage operations for inverting the soil.
Looking to the changing scenario, the cost of cultivation should be reduced at minimum level
with resource conservation. However, majority of the farmers do not perform tillage operations
every year and sometimes leaves the field fallow during Kharif and cultivate sorghum in Rabi in
medium deep to deep soils. Therefore, an attempt was made to find out low-cost tillage and
nutrient management practices, to study the effect of tillage and nutrient management practices
on soil quality, to minimize dependence on chemical fertilizers and to find out energy saving in
sustainable rabi sorghum production system under dryland condition.
