Abstract:
The experiment was carried out at Research farm of Deen Dayal Upadhyaya Centre of Excellence for Organic Farming of CCS Haryana Agricultural University, Hisar during the rabi season 2022-23 under organic system cultivation without using any chemicals to study the effect of organic manures and natural farming on growth, yield and quality of carrot. The experiment was laid out in RBD with eight treatments and three replications. Three different organic manures such as FYM, vermicompost, poultry manure alone and along with biofertilizers (Azatobacter and PSB) was applied. Treatment of cow based bio-formulations (Ghanajeevamrit and Jeevamrit) and control was also included as treatment where no fertilizer and manure were used. The study revealed significant improvements in almost all growth attributes and growth indices by combined application of organic manures along with biofertilizers. Among different combinations, vermicompost+ biofertilizer surpassed all other treatments by giving maximum plant height, fresh root and shoot weight, dry root and shoot weight, root length, shoot length, root diameter, root yield (283.4 qha^-1), shoot yield (183.0 qha^-1), total sugar, reducing sugar, non- reducing sugar, TSS, Absolute growth rate and crop growth rate. Also, the gross return (Rs. 425100 ha^-1), net return (Rs. 232873 ha^-1),), and BC ratio (2.21) during the experiment. It was also observed during the study that control treatment showed lowest findings among all the treatments.
