Increasing the nutrient use efficiency in major food
production systems has always been a major concern
because of escalating costs of production of crops, especially
with regard to nutrient management. ‘Researcher-
designed farmer managed trials’ were
conducted during 2013–14 through farmer participatory
research covering the major food production systems
in India. A total of 144 trials in rice–rice, 156 in
rice–wheat, 48 in rice–green gram and 60 in maize–
wheat systems were conducted with 7 treatments.
Across the various National Agricultural Research
Project zones and cropping systems, farmers applied
29%, 25%, 71% and 100% lower level of N, P2O5,
K2O and micronutrients respectively, than the recommended
dose. Application of recommended dose of
NPK + deficient micronutrients in all the systems recorded
higher yield over farmer package. Balanced
application of recommended NPK + deficit micronutrients
gave additional yield. The increase in agronomic
efficiency (AE) of nitrogen (two times on an
average), phosphorus (45%) and potassium (60%),
partial factor productivity and relative response was
also observed with the balanced application compared
to N, NP and NK alone. Higher increase of AE of N
and P was observed in rice–rice system while AE of K
was observed in rice–wheat system. Increase in net returns
was found to be 24.9%, 63.3%, 27.4% and
92.2% with the application of NPK + deficient micronutrients
over farmer practice in rice–rice, rice–
wheat, rice–green gram and maize–wheat systems respectively,
whereas the increase in cost of cultivation
due to addition of P, K and micronutrients was found
to be only 4.8%, 7.3%, 13.0% and 17.9% for the respective
systems.
