Tillage is an important agricultural operation which influences soil properties,
crop yield and environment. Nine combinations of three tillage practices
including conventional tillage (CT), minimum tillage (MT) and zero
tillage (ZT) were evaluated in fodder sorghum (Sorghum bicolor) + cowpea
(Vigna unguiculata) – wheat (Triticum durum) cropping system for 5 years
(2009–2014) on clay loam soil under limited irrigation. Continuous ZT
practices significantly improved surface soil organic carbon, bulk density,
infiltration rate and maximum water holding capacity. Carbon sequestration
rate, soil organic carbon stock and soil enzymatic activities were relatively
more under ZT than CT-CT practice. Higher fodder yield of sorghum + cowpea
was recorded with CT (kharif) while wheat grain yield with ZT (rabi).
However, the system productivity was statistically similar in all the tillage
treatments on pooled data basis. The economic benefits were also maximum
under ZT-ZT practice. The ZT-ZT practice recorded significantly lowest
energy input (17.1 GJ ha−1
) which resulted in highest energy use
efficiency (13.6) and energy productivity (518 kg GJ−1
). Thus, adoption of
ZT significantly improved soil health, stabilized crop yield, increased profitability
and energy use efficiency in the semi-arid agro-ecosystem.
