Abstract :
Rice fallow maize has been adopted in major
area of the Srikakulam district during Rabi with
conventional method of maize cultivation, sown behind
the plough after 2-3 ploughings which is highly laborious
and costly . The crop is subjected to terminal moisture
stress and requires more number of irrigations which is
a constraint in the district and resulted less yields and low
price. To combat, this new concept of zero tillage maize
emerged during 2012-13.The front line demonstrations
were conducted in various locations of Srikakulam
district of Andhra Pradesh during 2017 to 2020. Total 37
farmers from different villages for demonstration of zero
tillage maize for three consecutive years were selected.
The demonstrations were laid out on farmers' field as per
package of practices recommended by Acharya N. G.
Ranga Agricultural University. The farmers' practice was
considered as control plot in demonstration. The results
revealed that rise in yield of maize of 8092 Kgs/ha, 7530
Kgs/ha and 7514 Kgs/ha was recorded in the consequent
years in the demonstration plots over the control by
9.35%, 5.6% and 2.03% respectively. The cost of
cultivation has also reduced on Preparatory cultivation
and irrigation Up to Rs.4500/ha resulting in Benefit Cost
ratio of 1:2.63 when compared to the farmers
practice1:2.49 on an average. The Zero tillage maize
proved to be an effective technology for the improvement
of farmer’s income with reduced cost of cultivation on
land preparation, utilizes the residual moisture
minimizing the number of irrigations and preventing the
crop from terminal moisture stress in rice fallows when
compared to the farmer’s practice of field preparation
after rice cultivation. The impact of the FLDs on zero
tillage maize evidenced in increased crop coverage area
during rabi under Zero Tillage Maize was from 1500 ha
during 2016-17 to 5500 ha during 2020-21(Source: Dept.
of Agriculture, Srikakulam).
