Effect of conjoint application of nutrient sources and PGPR on soil microbiological properties of cauliflower

Abstract

The present investigation entitled “Studies on conjoint application of nutrient sources and PGPR on microbiological properties of cauliflower (Brassica oleracea var. botrytis L.) cv. Pusa Snowball K-1 was carried out at the Experimental Farm of Department of Soil Science and Water Management, Dr Y S Parmar University of Horticulture and Forestry, Nauni, Solan, (HP) during 2014-15 and 2015-16. The experiment was laid out in a randomized complete block design with three replications comprising seven treatments viz. T1(100% NPK + FYM), T2(100% NPK + FYM+ PGPR), T3(100% NPK+ 50% FYM and 50% VC on N equivalence basis + PGPR), T4 (75% NPK+50% FYM and 50% VC on N equivalence basis), T5 (75% NPK+50% FYM and 50% VC on N equivalence basis+ PGPR), T6 (50% NPK+ 50% FYM and 50% VC on N equivalence basis) and T7 (50% NPK+ 50% FYM and 50% VC on N equivalence basis + PGPR). The seedlings were transplanted at a spacing of 60 x 45 cm in 3 x 2 m size plots. Conjoint use of fertilizers, manures and PGPR significantly influenced soil microbial properties of cauliflower crop. Treatment T3 resulted in significantly maximum microbiological properties which was found statiscally at par with T5.
