    RESPONSE OF PHOSPHOGYPSUM TO VARIOUS CULTIVARS OF FODDER OAT (Avena sativa L.) IN SODIC SOILS
    (MULTILOGIC IN SCIENCE, 2018) Pal, P
    Oat is one of the most important cereal fodder crops of Rabi season. It provides soft and palatable fodder. Its fodder, on dry matter basis contains 10.0 -11.5 % crude protein, 55-63 % neutral detergent fiber, 30-32 % acid detergent fiber, 22.0-23.5 % cellulose and 17-20 % hemicelluloses when harvested at 50 % flowering stage of crop. Oat is also used as straw, hay or silage. Total world area under oats is approximately 13.9 million hectares. The production of oat is not being fully exploited because of the lack of proper information on its optimum fertilizer requirement. Among the different production factors, fertilizer application is one of the most important factors in limiting the production of oat crop.

    RESPONSE OF PHOSPHOGYPSUM TO VARIOUS CULTIVARS ON SOIL FER TIL ITY AND FODDER PRODUCTION OF OAT (Avena sativa L.) IN SODIC SOILS
    (Progressive Research – An International Journal, 2018) Pal, P
    The study was aimed to evaluate the entries of fodder crop and phosphogypsum levels on yield and effect on chemical properties of soil. The twelve treatment were comprised of one time application of four levels of phosphogypsum on basis of sulphur content (0, 125, 250 and 375 kgha-1) with three cultivar viz. NDO-1, NDO-2 and NDO-711 in randomized block design replication each treatment thrice. The phosphogypsum was applied through broadcast and surface incorporation. The half dose of nitrogen @ 100 kg N ha-1 though urea, and full dose phosphorus @ 40 kg P2O5 ha-1 through Diammonium phosphate applied at the time of sowing of the crop. The remaining half dose of nitrogen was top dressed in standing crop at 25 DAS just after first irrigation of the crop. The maximum fodder, dry matter and crude protein yield were obtained with the application of phosphogypsum @ 375 kg ha-1 (60 kg S ha-1) along with V3 (NDO-711) followed by phosphogypsum @ 250 kgha-1 and minimum was received with control with entry NDO-1. Subsequent reduction in pH and EC, build up of organic carbon, available nutrients viz. nitrogen, phosphorus and potassium with the application of phosphogypsum @ 375 kg ha-1 with the entry NDO-711.
