ABSTRACT

A field experiment was conducted during kharif, 2021 on sandy loam soils of Tirupati in a split-plot design with four proso millet varieties (TNAU 202, GPUP 8, GPUP 21 and PPV 1) in combination with three nitrogen levels (20, 40 and 60 kg N ha-1). The results of the experiment revealed that among the four proso millet varieties, PPV 1 recorded the higher grain and straw yield, nutrient uptake and lower amount of post-harvest soil available nutrients. Application of 60 kg N ha-1 markedly improved the yield, nutrient uptake and post-harvest soil available nutrients. The results concluded that the proso millet variety PPV 1 or TNAU 202 with the application of 60 kg N ha-1 was more productive and maintains soil health.
