Effect of PGPR and BCA on seed quality parameters in bell pepper (Capsicum annuum L.)

Abstract

An investigation was carried out during two consecutive years (2015-16 and 2016-17) at Experimental Farm of Department of Seed Science and Technology, Dr. Y. S. Parmar University of Horticulture and Forestry, Nauni, Solan-273230 (H. P.). The experiment was conducted on effect of plant growth promoting rhizobacteria and biocontrol agent on seed quality parameters of bell pepper. There were nine treatments including control and each treatment was replicated thrice. The data was analysed in factorial randomized block design. The study revealed that all the seed quality parameters like 1000 seed weight (6.63 g), per cent seed recovery (1.58), seed germination (93.26%), seedling length (12.39 cm), seedling dry weight (2.29 mg), seed vigour index- (SVI-L) (1156.03) and seed vigour index- (SVI-M) (213.69) were recorded maximum with treatment [PGPR (seed treatment) + T. harzianum (soil application)]. All parameters showed minimum in untreated control as compared to rest of the treatments. The study revealed that all the treatments of bioagents i.e. seed treatment, soil application and their combinations resulted in increase of all the parameters had significant impact on seed quality parameters of bell pepper. The effect of all the treatments was significantly higher during the trial conducted in 2015-16 as compared to the trial conducted in 2016-17.
