Application of Azospirillum and nutrients on yield, quality parameters and economics of black pepper

Abstract

A field experiment was conducted at Experimental Farm, Peruvannamuzhi to study the effect of Azospirillum, along with nutrients on yield of black pepper. The treatments consisting of various nutrients and bio-fertilizer Azospirillum were tested in split plot design and there had four replications. Recommended N 50% + Mg significantly increased the yield (1,741 g /plant) and accrued highest net return (Rs. 39,548) and benefit: cost ratio (1.9). No pronounced effect of inoculums and nutrient application on quality parameters of berries was observed.
