  • In India, wheat is grown in an area of about 29.06 million hectares with a production of 86.87 million ton (FAO, 2011). The yield of wheat increased after sixties and early seventies bringing the green revolution in India. In recent years, production of wheat crop in response to the increasing application rates of the input resources is experiencing a declining trend. India is second most populous country after China which houses 15% of global population (census 2011) within 2.42% of geographical land area of world.

  • The effect of 2 growth regulators, betaine and thiourea, was examined to learn the extent to which they can alleviate salinity-induced dormancy of wheat seeds. Germination velocity (as measured by Timson index) progressively decreased with increasing salinity, while thiourea and betaine, alone or in combination, elevated the germination velocity of wheat seeds.

  • Grain yields were linearly increased at 100% ETo while maximum IWUE was achieved at 80% ETo. Results suggest that the use of either on-farm priming or hydropriming of seeds for 12 h can be helpful in improving grain yields in late-sown wheat under both optimum as well as limited water conditions.

  • Considering current agricultural practices and certain indicators, it is impossible to comment on sustainability of these practices. Chemical fertilizers are among such unsustainable practices. Because of increasing mineral fertilizer costs and negative environmental impacts of these fertilizers, the interest in biological nitrogen fixation is increasing within the scope of sustainable agriculture (without significant yield losses).

  • Mutation breeding is one of the breeding methods used successfully in durum wheat for selecting lines with increased agronomic values. The aim of this study was to select mutant lines having a better agronomic potential than the mother variety Gediz-75 in the M6 and M7 generations. The mutants were derived from the variety Gediz-75 of durum wheat (Triticum durum Desf.).

  • An experiment was conducted during 2009-10 and 2010-11 at research farm of division of Agronomy, IARI, New Delhi, to study the effect of various doses and methods of zinc application on maize and wheat. The treatment consisted of control, 12.5 kg ZnSO4 ha-1 , 25 kg ZnSO4 ha-1 and foliar spray of 0.5 % ZnSO4 and two wheat Varieties ‘DBW 17’ and ‘PBW 343’. The grain, stover and biological yield of maize were significantly influenced by application of zinc during first year and the maximum yields were recorded with the application of 25 kg ZnSO4 ha-1 during both the year.

  • Major rice-wheat growing soils of Upper Gangetic Plains, India were studied and evaluated by considering soil-site characteristics by using qualitative and quantitative methods. The qualitative method employed were USDA land capability classification and land suitability classification, while the quantitative evaluation method includes Riquier's parametric approach. The land evaluation methods indicated that information on production potential of soils provide a basis for comparison among different soils.

  • Plants with dense suberized root hair and low suberization of cortical cells display lower stomatal density and open stomata which signify the higher demand of water absorption. Guaiacol peroxidase play remarkable role in suberin biosynthesis on epidermis, cortex accompanied with increased root diameter, and endodermis cell walls with hydrogen peroxide spray treatment under normal conditions for plant growth i.e. November. Hydrogen peroxide decreased the in-gel activity of the peroxidase in roots of both wheats.
