Nitrogen indices of wheat sown with happy seeder with skipped row techniques as affected by split nitrogen application
Author(s): R. K. HUNDAL AND J. S. KANG
Abstract: A field experiment was conducted to study the effects of skip row planting techniques and N application time on different nitrogen indices of happy seeder sown wheat in rice residues with two seasons (2011–12 and 2012–13). The experiment was laid out in split plot design and had 3 planting patterns and 6 nitrogen application treatments. In the planting patterns, M2 had higher values of agronomic use efficiency, nitrogen utilization efficiency (NUtE), nitrogen use efficiency, nitrogen uptake efficiency. While nitrogen harvest index (NHI) and nitrogen balance index (NBI) were higher in M1 followed by M3. Results showed that agronomic use efficiency, nitrogen utilization efficiency (NUtE), nitrogen harvest index (NHI), nitrogen balance index, and grain protein content (GPC) in wheat were significantly affected by split application of nitrogen over control treatment. Linear relationship of grain yield and grain protein content revealed that when wheat sown with skip row planting technique and N applied in three splits, resulted in higher N indices.
