ABSTRACT
Field experiments were conducted for four years from 2009 to 2012 to assess the performance of different basmati rice-based cropping systems in terms of yield responses, system productivity, soil health and relative economics under different organic sources and biodynamic cultivation practices in Uttarakhand (India). Two cropping systems i.e. basmati rice-chickpea-Sesbania (green manuring) and basmati rice-vegetable pea-maize+moong (biointensive) were evaluated under the management of different biodynamic practices. Among cropping systems(on four year pooled basis), basmati rice-chickpea-Sesbania system recorded significantly higher rice grain yield (3808 kg/ha) as compared to basmati rice-vegetable pea- maize+ moong system recording 3279 kg/ha. Treatment where biodynamic and Panchgavya were applied in conjunction with FYM(farm yard manure)+ EC(enriched compost)+ VC(vermicompost)+ NEOC (non-edible oil cake) recorded significantly superior grain yield of rice(3958 kg/ha on four year pooled basis) and rabi crops. Steady increase in system productivity was observed after four years of experimentation in basmati rice-vegetable pea-maize+moong system (5.95 per cent in 2012-13 over 2009-10) as compared to basmati rice-chickpea-Sesbania (43 per cent increase in 2012-13 over 2009-10). System productivity where organic sources were applied in conjunction with biodynamic practices+ Panchgavya(T5) was found to be superior in increasing the system productivity of basmati rice based cropping systems reporting 38.1 per cent increase over initial(2009-10). Soil organic carbon, available nitrogen, phosphorus, potassium, sulphur and micronutrients were found to be significantly higher under rice-chickpea-Sesbania system and among biodynamic treatments significantly higher organic carbon and available micronutrients was found with organic sources+ biodynamic practices+ Panchgavya (T5). Highest net returns on effective basis of four years pool of ` 146778/ha in rice-chickpea-Sesbania and ` 244922/ha in rice-vegetable pea-maize+moong were acquired where organic sources i.e. FYM+EC+VC+NEOC were applied in addition to biodynamic & Panchgavya (T5). The highest B: C ratio (3.48) was accrued when basmati rice-vegetable pea –maize + moong system was managed through organic sources i.e. FYM+EC+VC+NEOC in addition to biodynamic & Panchgavya (T5) as compared to basmati rice-chickpea-Sesbania.
