Abstract: The present study entitled “Response of Boron Levels and Application Methods on Growth and Yield of Rice (Oryza sativa L.)” in north- western plain zone of India was carried out at School of Agricultural Science and Engineering, IFTM University, Moradabad in 2018-19. The ten treatments T1 = 100% RDF (150 :60 :40 kg ha-1); T2 = 100% RDF + 0.5 kg B ha-1 (SA); T3 = 100% RDF + 0.5 kg B ha-1(SA) + 0.2% B spray at 25 & 50 DAT; T4 = 100% RDF + 0.5 kg B ha-1 (SA) + 0.3% B spray at 25 & 50 DAT; T5 = 100% RDF + 1.0 kg B ha-1(SA); T6 = 100% RDF + 1.0 kg B ha-1 (SA) + 0.2% B spray at 25 & 50 DAT; T7 = 100% RDF + 1.0 kg B ha-1 (SA) + 0.3% B spray at 25 & 50 DAT; T8 = 100% RDF + 2.0 kg B ha-1; T9 = 100% RDF + 2.0 kg B ha-1 (SA) + 0.2% B spray at 25 & 50 DAT; T10 = 100% RDF + 2.0 kg B ha-1 (SA) + 0.3% B spray at 25 & 50 DAT combination were tested in randomized block design (RBD) with three replication.
T10 observed significant increase in all yield attributes viz., no. of tillers per m2 area, panicle length (cm), number of filled grain panicle-1, number of unfilled grain panicle-1, 1000- seed weight (g), grain yield (q ha-1), biological yield (q ha-1) and harvest index respectively, over rest of the treatments. In T10 treatments significantly increased the no. of tillers m2 area (199.65, 210.70, 212.50 and 213.15) 30, 60, 90 and harvest stage, fresh weight (66.79 g, 147.50 g, 163.00 g and 163.05 g plant-1) at 30, 60, 90 and harvest stage, panicle length (31.55 cm), number of filled grain panicle-1 (191.20), number of unfilled grain panicle-1 (20.80), biological yield (7.7 t, 10.5 t and 18.1 t ha-1) and harvest index (42.26%) respectively.
