High-Value Crops’ Imbedded Intensive Cropping Systems for Enhanced Productivity, Resource-Use-Efficiency, Energetics and Soil-Health in Indo-Gangetic Plains

High-Value Crops’ Imbedded Intensive Cropping Systems for Enhanced Productivity,... An investigation was undertaken at New Delhi, India during 2011–2013 to assess the agro-economic potentiality of four promising high-value crops’ imbedded diversified intensive cropping systems (DICS) in order to diversify the cereal–cereal based rotations and owning maximum profitability in Indo-Gangetic Plain (IGPR) production systems. Cowpea–potato–mungbean (C–P–Mb) system proved as best viable option in realizing highest system-productivity in terms of mungbean-equivalent-yield (MEY), water-productivity and energy-relationships besides enhancing soil physico-chemical and microbiological properties; followed by Kharif onion–wheat–mungbean (O–W–Mb) system. C–P–Mb system also observed significantly highest net-returns, production and monetary-efficiencies. Application of 75 % recommended NPK (RDF) + vermicompost (VC) @ 5 t ha−1 registered highest system-productivity (MEY) and production-efficiency followed by 100 % RDF, respectively. Application of 75 % RDF + VC @ 5 t ha−1 also registered higher available N, P, soil–organic–carbon and DTPA-extractable micro-nutrients, besides enhanced microbial–biomass–carbon, respiratory and dehydrogenase activities.

Abstract

An investigation was undertaken at New Delhi, India during 2011–2013 to assess the agro-economic potentiality of four promising high-value crops’ imbedded diversified intensive cropping systems (DICS) in order to diversify the cereal–cereal based rotations and owning maximum profitability in Indo-Gangetic Plain (IGPR) production systems. Cowpea–potato–mungbean (C–P–Mb) system proved as best viable option in realizing highest system-productivity in terms of mungbean-equivalent-yield (MEY), water-productivity and energy-relationships besides enhancing soil physico-chemical and microbiological properties; followed by Kharif onion–wheat–mungbean (O–W–Mb) system. C–P–Mb system also observed significantly highest net-returns, production and monetary-efficiencies. Application of 75 % recommended NPK (RDF) + vermicompost (VC) @ 5 t ha−1 registered highest system-productivity (MEY) and production-efficiency followed by 100 % RDF, respectively. Application of 75 % RDF + VC @ 5 t ha−1 also registered higher available N, P, soil–organic–carbon and DTPA-extractable micro-nutrients, besides enhanced microbial–biomass–carbon, respiratory and dehydrogenase activities. Overall, C–P–Mb and O–W–Mb systems supplied with 75 % RDF + VC @ 5 t ha−1 may prove as viable alternative DICSs for enhanced system-productivity, profitability, water-productivity, energetics, and soil-health under irrigated IGPR.
