A field experiment was conducted to study the effect of nitrogen and phosphorous on growth and yield of finger millet (Eleusine coracana (L.) at Centurion University, Paralakhemundi during summer (February-May), 2018. The combination of four nitrogen levels (0, 30, 60 and 90 kg ha-1) and three levels of phosphorus (0, 20 and 40 kg ha-1) were tested in Split plot design with three replications. There was a significant improvement in plant height and yield attributes with the application of 90 kg N ha-1 as compared to lower levels of N application. With increase in levels of Phosphorus from 20 and 40 kg ha-1 has significantly increased yield. Significantly higher grain (1054kg ha-1) and straw yield (4369kg ha-1) were recorded with the application of 90kg N ha-1 and 40 kg P2O5 ha-1 while, the minimum yield was observed with 0 kg N ha-1 and 0 kg P2O5 ha-1.
Plant growth promoting rhizobacteria have been used to improve crop production. A total of 114 bacterial isolates were recovered from the rhizosphere soils of healthy plantation and vegetable crops grown in Andaman Islands. These isolates were evaluated in vitro for plant growth promoting traits, hydrolytic enzyme production and antagonistic activity. Among the isolates, NPB6 and MNB1 were positive to 8 out of 10 properties tested followed by NFB3, MKP3, NNB4 and NTB2. In the dual culture assay, NFB3 showed highest inhibition against the plant pathogen Macrophomina spp (33.3%) and S. rolfsii (23%). Six most promising isolates were selected and identified as Bacillus and Pseudomonas spp. on the basis of Microbial Identification System and 16S rDNA. These isolates significantly increased the seed germination, vigor index, radical and plumule length however, the individual isolates effect varies with crop. All the six isolates enhanced the root and shoot length of brinjal, chilli and okra seedlings while Bacillus cereus (NPB6) in brinjal, B. stratosphericus (NFB3) in chilli and Pseudomonas fluorescens (NNB4) in okra were most effective. The promising isolates can be used in combination with other beneficial native microbes for plant growth promotion even under abiotic stresses and promotion of organic agriculture.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
