SUMMARY
The present study was carried out at Agricultural Research Station, Keshwana, Jalore during winter cycle 2018-19 and 2019-20 on “Effect of different levels and foliar application of nitrogen in oat under transitional plain of Luni basin”. The soils of the experimental fields were loamy sandy in texture, alkaline in reaction, low in organic matter and nitrogen content and low to medium in Phosphorous medium to high in potassium content. The experiment used a split plot design with three treatment in main plot and three plot in sub plot repeated with three times. The experiment included three levels of nitrogen, namely 50 %, 75% and 100 % of recommended nitrogen i.e. F1, F2 and F3 and 4 urea spray namely water spray, 2% urea spray at 15, 30 and 45 DAS was used. Application of nitrogen as a basal and foliar had a significant effect on the growth, green and dry fodder yields of the oat. Application of 100% RDN showed a significant higher results with respect to tillers per plant, plant height, CGR, RGR, Dry matter percentage during both the year of experiment but it was recorded at par with the 75% RDN during both the years. Green and dry fodder yields during 2018- 19 were recorded significantly higher with the Application of 75% RDN, while in succeeding year it was recorded higher with 100% RDN. Foliar spray of urea 2% at 30 DAS recorded significant effect on the growth and yield parameters of the fodder oat but it was at par with the 45 DAS. Positive linear relationships were observed with respect to nitrogen application and green (R2= 0.7826) and dry (R2= 0.8019) fodder yields of oat.
