In order to investigate the influence of exogenous application of calcium (Ca) on its accumulation in finger millet, two genotypes (GPHCPB-1 and GPHCPB-45), which posses low and high grain Ca contents, respectively, were subjected to regular fertigation of varying levels of Ca in Hoagland’s nutrient medium. The responsiveness of both the genotypes towards increasing exogenous application of Ca (0.1, 5.0, 10 and 20) was determined in terms of changes in tissue Ca levels, agromorpho-physio-biochemical parameters. Sharp increase of Ca content in root, stem and spike was observed up to excess level of Ca (10 mM) in GPHCPB-1 while in case of GPHCPB-45 an increase in Ca content was observed only up to sufficient level of Ca (5 mM) and above that its accumulation remained constant or declined in both the genotypes. In case of leaf the level of Ca increased linearly at all concentrations of supplied Ca in both the genotypes. Both the genotypes behave differentially as GPHCPB-45 genotype accumulated more Ca and was also superior in root length, root dry matter accumulation, plant height and relative water content at Ca deficient condition (0.1 mM) as compared to GPHCPB-1 genotype. The continuous rise in stem diameter, biomass, seed yield, chlorophyll content, SPAD value, seed oxalic acid and phytic acid content were recorded in both the genotypes up to excess or toxic levels of supplied Ca. On the basis of present study it was concluded that Ca accumulation in plant is determined by both genetic (genotype dependent) as well as environmental factors (availability of Ca in rhizosphere).

Finger millet is a staple food crop of many communities in Africa. The crop is highly nutritious and has incredible grain storage quality. Limited research investment in finger millet in the past has resulted in poor yields and there are currently no commercial hybrids. We investigated the response of different finger millet genotypes (Okhale-1, Gulu-E, KACCIMMI-72, IE 2872, IE 4115 and U-15) to the application of a plant growth regulator hormone (Ethrel). Six elite Kenyan finger millet varieties with contrasting agronomic traits were crossed in a 6 x 6 diallel pattern. To enhance male sterility across female parents, we subjected the plants to Ethrel at concentrations of 1,500ppm, 1,750ppm and 2,000ppm against a 0ppm check. Dwarfing of sprayed plants that resulted in less lodging and ultimately higher yields were observed among plants sprayed with Ethrel at different concentrations. Ethrel application at 2,000ppm had the most dwarfing effect on plants while spraying plants with 1,500ppm of Ethrel resulted in increased grain weight. Although our results demonstrate overall positive effect of Ethrel on finger millet production, the optimum concentrations for more efficient hybridization will still need to be determined.

Biofertilizers have been used as sources to improve plant nutrients in sustainable agriculture. Biofertilizers are low cost, renewable sources of plant nutrients which supplement chemical fertilizers. Mycorrhizal fungi are a major component of agricultural natural resources and members of kingdom fungi. The term ‘mycorrhiza’ is derived from Greek word which means ‘fungus root’. Earthen pot experiments were carried out to study the inoculation effect of Arbuscular Mycorrhizal (AM) fungi (Glomus mossease), Azospirillium brasilense and PSB on plant height, dry weight of root and shoot, per cent root colonization, spore number, P and N uptake. Experimental pots were filled with 4 kegs of sterilized soil and maintained in green house at 25-30 °C temperature. Single inoculation of AM fungi and combined inoculation of AM fungi with Azospirillium brasilense or PSB was found to be moderately increased in all the growth parameters. However triple inoculation of AM fungi, Azospirillium brasilense and PSB was found to have highest growth parameters.
