Rice-wheat cropping system (RWCS), a lifeline for the majority of the population in
South Asia is under stress, due to the imbalanced and indiscriminate use of fertilizers. Therefore,
we conducted an on-farm study at eight locations (Amritsar, Katni, Nainital, Samba, Pakur, Kanpur,
Ambedkarnagar, and Dindori) covering five agro climatic zones of six Indian states (Jammu and
Kashmir, Punjab, Uttarakhand, Uttar Pradesh, Madhya Pradesh, and Jharkhand) to (i) calculate the
partial factor productivity (PFP) and agronomic use efficiency (AUE) to judge the response of NPK
and Zn on grain yield of rice and wheat in RWCS and (ii) to work out the economic feasibility of
different combinations of NPK in rice and wheat. Seven fertilizer treatments: Control (0-0-0), N
alone (N-0-0), NP (N-P-0), NK (N-0-K), NPK (N-P-K), NPK+Zn (N-P-K-Zn), and FFMP (Farmers
Fertilizer Management Practice) were assigned to all the locations. The levels of applied nutrients
were used as per the standard recommendation of the location. The average of all the locations
showed that the use of NP enhances the grain yield of rice and wheat by 105% and 97% over control,
respectively. System productivity of RWCS was expressed in terms of rice grain equivalent yield
(RGEY), Mg ha􀀀1. Among the locations, Samba recorded the lowest productivity of RWCS with
fertilizer treatments. In contrast, the highest productivity of RWCS with fertilizer treatments was
recorded at Amritsar, except with NPK and NPK+Zn fertilization, where Katni superseded the
Amritsar. An approximately 3-fold productivity gain in RWCS was recorded with the conjoint use
of NP over control across the locations. Overall, the results of our study showed that the balance
application of NPK increased the productivity of RWCS 245% over control. Partial factor productivity
of Nitrogen (PFPn) N alone in rice varied across locations and ranged from 19 kg grain kg􀀀1 N at
Pakur to 41 kg grain kg􀀀1 N at Amritsar. PFPn of N alone in wheat also ranged from 15.5 kg grain
kg􀀀1 of N at Ambedkarnagar to 28 kg grain kg􀀀1 N at Amritsar. However, across locations the
mean value of PFPn of N alone was 29 kg grain kg􀀀1 N in rice and 21 kg grain kg􀀀1 N in wheat.
PFPn increased when combined application of N and P sorted in both rice and wheat across the
locations. Similarly, combined application of NPK increased partial factor productivity of applied
phosphorus (PFPp) in both the crops at all the locations. The combined application of NPK increased
the PFPk for applied K at all the location. The response of K application with N and P when averaged
over the location was 114% in rice and 93% in wheat over the combined use of N and K. In our study,
irrespective of fertilizer treatments, the agronomic use efficiency of applied N (AUEn) and agronomic
use efficiency of applied P (AUEp) were greater in rice than in wheat across the location. With regards
to the economics, the mean net monetary returns among the fertilizers treatments was minimum (INR
29.5 103 ha􀀀1) for the application of N alone and maximum (INR 8.65 103 ha􀀀1) for application
of NPK+Zn. The mean marginal returns across the locations was in order of N alone > NK > FFM >
NPK > NP > NPK+Zn.
