摘要

In rice-wheat production system in Indo-Gangetic Plains (IGP), intensive tillage, water and blanket fertilizer recommendations have led to high production cost, diminishing yield and factor productivity, and increasing greenhouse gas emissions. Climate-smart agricultural practices (CSAPs) have been increasingly adopted in this region to address the challenges related to natural resource degradation and climatic risk management and low input use efficiency. But, optimal nutrient management practices for conservation agriculture (CA)- based rice-wheat (RW) production in the IGP are still scarce. Opportunities exist to further improve the yield and resource use efficiency of RW system by using site-specific nutrient management (SSNM) practices. A multi-location farmer's participatory trail was conducted with six treatments referred to as scenarios (S). Six scenarios were replicated three times at three farmer's fields in Karnal district of Haryana. Altogether, six scenarios compared were: Farmer's practice (FP) (SI); improved FP (IFP) with low intensity of adaptive measures (S2); IFP with high intensity of adaptive measures (S3); climate smart agriculture (CSA) with low intensity of adaptive measures (S4); CSA with medium intensity of adaptive measures (S5); and CSA with high intensity of adaptive measures (S6). Results revealed that rice yield was not much affected by the different crop management practices in two years. However, CSAPs with different intensity levels (S4 to S6) produced 15% higher wheat yield (2 years' mean) compared to SI. CSAPs with high intensity of adaptive measures (S6) recorded 9% higher system productivity compared to FP. CSAPs improved the factor productivity of N by 34 and 59% (2 years' mean) in rice and wheat, respectively, as compared to FP. The improvement in yield, and N-factor productivity was higher with full portfolio of CSAPs (S6) compared to all the other scenarios omitting one or more practices in the portfolio. However, omitting some practices had more effect than the others providing guidelines as to what practices are more important and should form the priority in the portfolio of CSAPs that help in maximizing crop productivity and input use efficiency while minimizing the adverse effects of associated climatic risks by improving adaptive capacity and reducing the environmental footprints.
