Abstract
An investigation was carried out at Agricultural research farm of Banda university
of Agriculture and Technology, Banda UP on the prescribed topic “Performance of maize
(Zea mays L.) hybrid under different tillage and nutrient management practices”
during the Kharif season 2021. The comprehensive aim of experiment was to explore the
most appropriate tillage practices for the maize crop that could produce optimum yield
more remunerative along with better profitability and also to find out effective nutrient
management practices that suited well to the region. The experiment comprises of two
factor treatments conducted in split plot design with three main plot factor and three subplot factor. The total combination of treatments was nine and each treatment replicate
thrice. The main plot consisted of the tillage practices namely, zero tillage, conventional
tillage and permanent bed. Further, each main plot had divided in to 3 sub-plots held three
nutrient management practices viz. 33% recommended dose of nitrogen (40 kg N ha-1
),
100% recommended dose of fertilizer (N:P:K-120:60:50 kg ha-1
) and site specific nutrient
management (N:P:K-160:50:60 kg ha-1
).
The soil in which experiment conducted was silty clay and their pH value 7.89, EC
0.55 dSm-1
and total organic carbon was 0.76%. The observation in growth parameter and
quantitative and qualitative attributes of maize were recorded as per schedule. During the
field study it was observed that the highest growth parameter viz. plant height, number of
leaves plant-1
, dry matter accumulation and maximum yield attributes namely, cobs ha-1
,
grains cob-1
, seed index and greater profitability in terms of economic return were recorded
under the zero tillage practice employed to the maize. Among the nutrient management
practices the site specific nutrient management (SSNM) practice produced maximum
growth, yield (economic yield and biological yield) and yield attributes and also economic
return (gross return, net return). Among all interaction of tillage and nutrient management
practices, the zero tillage practice along with SSNM produced maximum output, more
remunerative and this combination practically feasible and economically viable to
production of maize.
