Abstract:

An experiment was carried out to know the influence of application of different basal dose (50 and 80 % N) of liquid fertilizer Urea Ammonium Nitrate at different application depth (7 and 9 cm) on wheat growth parameters. The basal dose was provided with UAN and thereafter by foliar spray of UAN. Different crop growth parameters like germination count, plant height, number of tillers per m row length, grain yield and biological yield of wheat crop were studied. Plot with urea application was taken as control plot. The minimum germination count was observed when UAN in higher amount (80% N as basal dose) was placed at depth of 7 cm from surface. This may be because of toxicity of higher concentration of UAN placed in close proximity (3 cm distant) of seed. Number of tillers per m in the treatment 80% basal does of UAN (120 kg N/ha) at 9 cm depth were either at par or significantly higher compared to number of tillers observed in recommended dose of fertilizer (50% basal dose of Nitrogen through Urea @ 150 kg N/ha). Among all the treatments, placement of 80% basal does of UAN at 9 cm from soil surface give the highest number of tillers per metre row length. The highest and lowest biological yield of 1680g/ m2 and 1320 g/m2 was observed in treatments observed when 80% basal dose of N was applied at 9 cm and 7 cm, respectively. The higher biological yield observed in 80% N as basal dose compared to 50% N may be due to effect of Nitrogen on vegetative growth of wheat.
