Abstract DEPARTMENT OF AGRONOMY COLLEGE OF AGRICULTURE, DAPOLI. Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli – 415 712, Dist. Ratnagiri (Maharashtra) Title of Thesis : Effect of different levels of nitrogen on performance of fodder oat (Avena sativa L.) varieties under lateritic soil of Konkan region. Name of the student : Mr. Sawant Sagar Mangesh Registration No. : 2330 Name of Research Guide : Dr. S. B. Bhagat Agronomist (ECF), Agriculture Research Station, Palghar, Dist. Palghar 401404. Year of award of degree : 2016 THESIS ABSTRACT The field experiment was conducted on plot no. 20 of “B†block of Agronomy Department Farm, College of Agriculture, Dapoli, Dist. Ratnagiri during rabi season 2015-16 to study the “Effect of different levels of nitrogen on performance of fodder oat (Avena sativa L.) varieties under lateritic soil of Konkan region.†The experiment was laid out in a split plot design with three replications. The main plot treatments were three oat varieties, viz., RO-19 (V1), Kent (V2) and OS-6 (V3). The sub plot treatments comprised of four nitrogen levels viz., 40 Kg N ha-1 (N1), 60 Kg N ha-1 (N2), 80 Kg N ha-1 (N3) and 100 Kg N ha-1 (N4). Thus, there were in all 12 treatment combinations. The gross plot size was 4.5 m X 3.00 m and net plot size was 3.9 m X 2.4 m, respectively. The soil of the experimental plot was uniform, level and well drained. It was sandy clay loam in texture, medium in available nitrogen (284.2 Kg ha-1) and potassium (264.22 Kg ha-1), low in available phosphorus (10.80 Kg ha-1), medium in organic carbon content (0.97 %) and slightly acidic in reaction (pH 5.68). The sowing was done in the experimental plot on 6th November, 2015 by drilling method at a distance of 30 cm in between the rows. The other common package of practices was followed time to time and periodical growth observations were recorded. Results revealed that variety RO-19 recorded significantly higher growth as well as yield attributes resulting in higher green and dry fodder yield (q ha-1) followed by varieties Kent and OS-6. The chemical studies showed that significantly higher values of Crude Protein, Crude Fibre, Neutral Detergent Fibre, N, P and K content in dry fodder and total uptake were recorded by oat variety RO-19 than Kent and OS-6. However, variety OS-6 showed maximum Acid Detergent Fibre content than rest of the varieties. The highest net returns of Rs. 56103.86 ha-1 with B : C ratio 1.93 was obtained from variety RO-19. Application of 100 Kg N ha-1 recorded significantly higher growth as well as yield attributes resulting in higher green and dry fodder yield (q ha-1) as compared to 80, 60 and 40 Kg N ha-1. Significantly higher values of Crude Protein, Crude Fibre, Acid Detergent Fibre, Neutral Detergent Fibre, N, P and K content in dry fodder and total uptake by oat were recorded due to application of 100 Kg N ha-1. The highest net returns of Rs. 60157.60 ha-1 with B : C ratio 1.97 was obtained due to application of 100 Kg N ha-1. In respect of economics, it was observed that the treatment combination V1N4 (RO -19 + 100 + 100 Kg N ha Kg N ha Kg N ha -1) has given significantly highest net returns Rs. 69088.56 ha-1 and B : C ratio (2.09).
