Commercial viability of three cytoplasmic-nuclear male sterility (CMS) systems (A4, A5 and Av) as potential alternatives to the most widely used A1 system in pearl millet (Pennisetum glaucum (L.) R.Br.) was evaluated in terms of stability of complete male sterility of four isonuclear A-lines (81A1, 81A4, 81A5 and 81Av) and the level and stability of male(More)
 Soil P availability and efficiency of applied P may be improved through an understanding of soil P dynamics in relation to management practices in a cropping system. Our objectives in this study were to evaluate changes in plant-available (Olsen) P and in different inorganic P (Pi) and organic P (P0) fractions in soil as related to repeated additions of(More)
Genetics of micronutrients and their relationships with grain yield and other traits have a direct bearing on devising effective strategies for breeding biofortified crop cultivars. A line × tester study of 196 hybrids and their 28 parental lines of pearl millet (Pennisetum glaucum (L.) R.Br.) showed large genetic variability for Fe and Zn densities with(More)
Phytoremediation of soils contaminated with heavy metals has received considerable attention in recent years. Because of the contamination of food and vegetable crops with heavy metals, greater emphasis has been given to the cultivation of floriculture plants for remediation of the contaminated soils. In the present experiment, the response of rose to soil(More)
Research findings are often not adopted by farmers, for which many reasons have been suggested including poor communication between researchers and farmers. Mother–baby trials, involving on-farm participation to introduce and test technology options, was used to evaluate possible nutrient management technologies in a soybean–wheat system on vertisols(More)
A vesicular-arbuscular mycorrhizal fungus, identified asGlomus mosseae Gerdemann and Trappe, was found to occur in groundnut and some other hosts. In groundnut roots under experimental conditions, the fungus showed three phases of development-a lag phase of 3–4 weeks by the end of which formation of vesicles was noticed, a phase of gradual development upto(More)
There is worldwide concern over the increase use of nanoparticles (NPs) and their ecotoxicological effect. It is not known if the annual production of tons of industrial nanoparticles (NPs) has the potential to impact terrestrial microbial communities, which are so necessary for ecosystem functioning. Here, we have examined the consequences of adding the(More)
A d2 dwarfing gene in pearl millet [Pennisetum glaucum (L.) R. Br.] is currently being extensively used for the development of hybrid parents. Its effect on grain yield and yield components is poorly understood. Twelve pairs of tall and dwarf near-isogenic lines developed in the diverse genetic background of three composites were evaluated for grain yield(More)
Long period of intensive crop cultivation deplete the available soil silicon (Si). Depletion of available Si in the soil could be one of the possible limiting factors amongst others contributing to declining yields. The lower values for Si in the soil can be justified due to (i) severe and frequent soil erosion and sediment transportation. (ii) Usually(More)
