Response of bio-enhancers on plant growth and yield of broccoli (Brassica oleracea L. var. Italica) F-1 hybrid green magic

Abstract

The investigation was carried out during winter season of 2017-18 at Agricultural farm, School of Agricultural Sciences & Engineering, IFTM University, Moradabad (U.P.). The experiment was laid out in Randomized Block Design (RBD) with 7 treatments and was replicated thrice. Different combinations of Panchgavya (4%) Jivamrita (20%) and vermiwash (1:5 times dilution), RDF (N:P:K @ 120:60:60 Kg/ha) and control were used as treatments. On the basis of above study, it was found that RDF (N:P:K @ 120:30:30 kg/ha) was proved to be a superior treatment in terms of yield of broccali (19.03 t/ha), but is was found to be significantly similar with T4 (Panchagavya 4% + Jivamrita 20%) and T5 (Panchagavya 4% + Vermiwash 1:5 times dilution). The yield recorded in T4 and T5 were 15.69 and 17.00 t/ha, respectively. These results show the importance of bio-enhancers in increasing the yield of broccali. Bio-enhancers being completely organic in nature were capable of producing yield levels significantly comparable to that of RDF supplied through chemical fertilizers. Apart from yield they also have positive and significant effect on various physical, chemical and microbial properties of soil and environment.
