| Abstract | ||
| Canola (Brassica napus L.) cv. Pactol was experimented for growth and seed oil production due to farm yard manure (FYM) and urea in presence of diazotrophic bio-preparates applied in clay and sand soils. Introduction of diazotroph inocula was more supportive to canola grown in sand soil than the corresponding cultivated in clay soil, a phenomenon observed with all growth parameters determined. Among the microbial products, rhizobactren acted more efficiently compared to others. Comparative variations in chemical characteristics of both soils due to diazotroph formulations were very contradicting, some inocula were successful in improving sand properties while others showed more pronounced modifying influence in the heavy textured clay soil. In the majority of cases, response of canola to urea application was more evident in sand than clay soil. On the contrary to the effect of mineral- and bio-fertilizers, canola grown in clay soil responded, to higher extent, to FYM. Due to various fertilization regimes, no distinct trend, among both soils, was recorded in respect to chemical properties. | ||
