Abstract

The use of organic formulations is gaining attention in Indian agricultural system and has a potential to fulfill the food demand. The aim of this study was to investigate the effect of seed priming and direct application of agro-organic formulations on the growth of Triticum aestivum L. and Brassica nigra in pot studies. Four different agro-organic formulations viz. traditional and modified Panchagavya and Jeevamrit at different concentrations (1:50 to 1:200) were used for seed priming and direct soil application. Seed primed with respective organic formulations were observed for germination pattern for 8 days. For direct application method, sterile soil was used and growth parameters were studied for 10 and 8 days in wheat and mustard respectively. All the treatments were kept under controlled condition of temperature of 24±2°C and 1000 lux throughout study. Seed priming showed significantly higher germination percentage and seed vigour index (SVI) in wheat (98% and 2216) when primed with modified formulation, while in mustard (64% and 684) when primed with traditional formulation as compared to control (autoclaved distilled water). Direct soil application showed significant difference in the germination percentage (100%), SVI (1205 and 1443), shoot length (10.3cm and 10.63cm), root length (5.7cm and 7.53cm) and seedling length (12.06cm and 14.38cm) of wheat and mustard respectively on comparing with control when subjected to treatment with traditional formulation for wheat and modified formulation for mustard. Further studies of agro-organic formulations in field will enhance our knowledge about the mechanism to increase the crop yield.
