A field and pot experiment entitled as ‘Influence of cultivation methods and nutrient management on productivity and nutrient dynamics in rice (Oryza sativa L.) wheat (Triticum aestivum L.) cropping system’ was conducted on sandy clay loam soil in sub-tropical and semi-arid type climate. Field experiment was conducted at Research Farm of ICAR-Indian Agricultural Research Institute, New Delhi, India during rainy/Kharif and winter/Rabi season of 2013-14 and 2014-15; while pot experiment was conducted in 2013-14 in net house of Agronomy division. The soil of experiment field had 257 kg ha-1 alkaline permanganate oxdisable nitrogen (N), 17 kg ha-1 available phosphorus (P), 327 kg ha-1 1 N ammonium acetate exchangeable potassium (K) and 0.54% organic carbon. The p H of soil was 7.6 and DTPA-extractable zinc (Zn) was 0.85 mg kg-1 of soil. Acetylene reductase activity (ARA), soil chlorophyll, dehydrogenase activity and microbial biomass carbon (MBC) of soil at start of experiment was 0.89 n mole ethylene g-1 hr-1 , 0.23 mg g-1 of soil, 9.4 µg TPF g-1 of soil h-1 and 71.5 µg g-1 of soil, respectively. Field experiment was conducted in split-plot design with three methods of cultivation in both rice (puddled transplanted rice (PTR), system of rice intensification (SRI) and aerobic rice system (ARS)) and wheat (conventioned drillsown wheat (CDW), system of wheat intensification (SWI) and zero tillage wheat (ZTW)) as main plots and nine nutrient management options were same for both crops as sub-plot treatments viz. control (N0P0Zn0), recommended dose (N120P25.8), recommended dose (N120P25.8) + Zn, 75% recommended dose (N90P19.35), 75% recommended dose (N90P19.35) + Zn, 75% recommended dose (N90P19.35) + Anabaena sp. (CR1) + Providencia sp (PR3), 75% recommended dose (N90P19.35) + Anabaena sp. (CR1) + Providencia sp (PR3)+ Zn, 75% recommended dose (N90P19.35) + AnabaenaPseudomonas (An-Ps) biofilmed formulation and 75% recommended dose (N90P19.35) + Anabaena- Pseudomonas (An-Ps) biofilmed formulation + Zn. Results of field experiment revealed that, all growth parameters studied in rice such as plant height, tiller m-2 , shoot dry matter production, leaf area index (LAI) and crop growth rate was remained identical in PTR and SRI methods of cultivation and both these methods stand statistically superior to ARS. Yield attributes of rice had 438 highest values in SRI which was closely followed by and remained on par with PTR. Both these methods had significantly higher values for all yield attributes than ARS. Grain yield of rice was highest in SRI in both years (4.10 and 3.97 t ha-1 , respectively) which was on par with PTR (4.08 and 3.95 t ha-1 , respectively); while yield in ARS (3.93 and 3.80 t ha-1 , respectively) was statistically inferior than both PTR and SRI method in both years. Straw yield, hulling percentage (%), milling % and head rice recovery (%) followed similar trend as that of grain yield of rice. Among nutrient management options, all growth and yield attributing parameters along with grain and straw yields of rice was found highest in recommended dose (N120P25.8) + Zn which remained on par with two other treatments viz. 75% recommended dose (N90P19.35) + CR1+ PR3+ Zn and 75% recommended dose (N90P19.35) + An-Ps biofilmed formulation + Zn. These three treatments stand statistically superior to rest of the treatments in all three methods of cultivation in both years of experiment. In case of wheat, growth and yield attributes were significantly higher in ZTW as compared to both CDW method and SWI; while CDW and SWI remained on par to each other in both years of experiment. Grain yield of wheat was significantly higher in ZTW (4.61 and 4.52 t ha-1 , respectively) in both years as compared to both CDW and SWI and similar trend was observed in straw and biological yields. Cost of cultivation was lowest in ZTW in both years of experiment (24.95 and 27.39 ` x 103 ha-1 ) as compared to other methods and this led to significantly higher net returns and B:C ratio in ZTW. Among nutrient management options three treatments viz. recommended dose (N120P25.8) + Zn, 75% recommended dose (N90P19.35) + CR1+ PR3+ Zn and 75% recommended dose (N90P19.35) + An-Ps biofilmed formulation + Zn had significantly higher biometric parameters, yield attributes and yield of wheat as compared to all other treatments. Gross returns, net returns and B:C ratios were also recorded significantly higher in same treatments during both years.
