Effect of pruning levels and bio-fertilizers on production of rose cut flower

Abstract

The experiment was carried out at the Deptt. of Horticulture K.A.P.G., college, Allahabad (U.P.) during the year 2005-06. Two year old well established rose plants were taken for the study. The design was used 52 Factorial RBD with three replications. Two factors i.e. pruning and bio-fertilizer each with five levels were tried to speculate the vigor, yield, quality and economy of cut flower. The number of cut flowers per bush were recorded highest (16.18) when pruned at five bud with Recommended Dose of Fertilizers (RDF) + soil applied bio-fertilizers (SAB) + foliar spray of vermiwash. Deeper the pruning lower the cut flower number per bush were observed. Quality blooms were found to increased with increase in severity of pruning up to one bud level. The recovery of grade C flowers with four and five bud level were observed and no such kind of cut flower was recovered when pruned at 3,2 & or 1 bud level. Bio-fertilizers influenced significantly the number of cut flowers per bush and grade too. Number of cut flowers per bush at same level of pruning were found significantly greater with F4 (SAB + vermiwash spray) followed by F3 (SAB + Biodynamic), F2 (SAB + Horne manure), F1 (SAB) and F0, Control (RDF). Conclusively T14 (pruned at 3 bud + SAB + foliar spray of vermiwash) treatment was found best in terms of economy of rose cut flower production at field level.
