Effect of pink pigmented facultative methylotrophs (PPFMs) and plant growth promoters on yield and nutrient uptake of semi dry rice

Abstract

Water and nutrient availability are two major constraints in most rice-based rainfed shallow lowland systems of Asia. Biotic and abiotic stresses interacts which leads to low productivity and widespread poverty in this environment. Field experiment was conducted from kharif 2017-18 to study the effect of Pink Pigmented Facultative Methylotrophs (PPFMs) and growth promoters on growth and yield of semi dry Rice. Introduction of direct dry seeding of rice, in upland environment was found to be used in water scarcity condition. Among the different combinations of PPFM and growth promoters, application of 100% RDF + Azophos as soil application @ 2 kg ha-1+ PPFM as foliar application 500 ml ha-1 registered significantly higher growth attributes, yield and nutrient uptake at flowering and harvest stages which was followed by RDF + Brassinolide (1 ppm).
