dc.description.abstractThe world’s one-third population is dependent on wheat Triticum aestivum L. for their food requirement. It contains higher protein than the other major grains. The indiscriminate use of fertilizers (Urea, D.A.P and M.O.P) are resulting in nutritional imbalances in soil, environmental hazards and a rise in production costs. Conventional nitrogenous fertilizers, can be lost or rendered inaccessible to plants by processes such as leaching, NH3 volatilization, denitrification, immobilization, and fixing in the soil solids as NH4-N which results 30-40 % fertilizer use efficiency. Therefore, to increase the nitrogenous fertilizer use efficiency and reduction of their ill effects there is need to use nano-nitrogen. Therefore, to access the response of wheat to foliar application of nano-nitrogen, the field and lab experiments were planned. The treatments comprised of T1- RDN (60:30:20 kg/ha), T2- 75 % RDN, T3- 50 % RDN, T4- RDN + nN (T), T5- RDN + nN (F), T6- RDN + nN (T+F), T7- 75 % RDN + nN (T), T8- 75 % RDN + nN (F), T9- 75 % RDN + nN (T+F), T10- 50 % RDN + nN (T), T11- 50 % RDN + nN (F), T12- 50 % RDN + nN (T+F), T13- nN (T), T14- nN (F), T15- nN (T+F), were evaluated in randomized complete block design with two replications at REC, Gaja during the rabi season 2020-2021. The seed quality parameters of harvested wheat seed were accessed in lab in complete randomized design with four replications. The significantly higher plant growth parameters and seed yield were recorded in 75 % RDN + nN (T) (2ml/litre water) than the RDN (60 kg). The treatment 75 % RDN + nN (T) and 75 % RDN + nN (T+F) gave 26 % and 11 % more grain yield, respectively as compared to the RDN. The maximum B:C ratio (2.9: 1) was also registered with 75 % RDN + nN (T). The seed quality attributes like germination percentage, seedling fresh weight, seedling dry weight, vigour index I and II, speed of germination, germination percentage in cold test and water sensitivity test were recorded significantly higher in 75 % RDN + nN (T+F) than the RDN. Based on the present experiment, 75 % of RDN (60 kg) + nN (T) @ 2ml/litre water might be beneficial for higher seed yield and quality of wheat under rainfed condition of mid hills of Uttarakhand.en_US
