Low seed rate at surface sowing enhance resilience of physiological parameters and economics of wheat (Triticum aestivum).

摘要

A field experiment was conducted during 2009-10 to investigate the effect of seed rates (40, 60, 80 and 100 kg/ha) and seeding depths (2, 4 and 6 cm) on growth, physiological parameters and economics in wheat (var GW 273). Study was carried out in agricultural farm Department of Agronomy, JNKVV, Jabalpur located in Kymore Plateau and Satpura Hills agro-climatic zone of Madhya Pradesh. As results indicate plant height, crop growth rate (CGR) and relative growth rates (RGR) increased significantly in 80 kg/ha seed rate as well as 2 cm sowing depth. The CGR was significantly correlated with grain yield with different seed rates as well as sowing depths. Results revealed that along with increases n CGR, seeds @ 80 kg/ha sown at 2 cm depth significantly increased dry matter production and grain yield in wheat. We conclude that these agronomical practices may prove to be beneficial to enhance the resilience and yield of wheat crop in this part of the agro-climatic zone.
