Enhancement of wheat productivity through efficient nutrient management practices

Abstract

A field experiment was conducted during the winter season of 2014 and 2015 at the AB block farm
of Bidhan Chandra Krishi Viswavidayalaya, Kalyani, to find out effect of different organic source
of nutrient along with nitrogen levels with its application time on growth and yield of wheat (Triticum
aestivum (L.) emend. Fiori & Paol.). Application of FYM @10 t/ha produced maximum grain (4.12 t/
ha) and biological yield (8.93 t/ha), and was at par with FYM @15 t/ha and significantly superior to
other treatment of main plot. In subplot treatments, the grain and biological yield of wheat increased
significantly with recommended nitrogen application before irrigation (BI), and was at par with the
site specific nutrient management (SSNM) treatment. This treatment recorded 127.1 and 13.4% more
grain and biological yield, respectively over the control. Further, with subplot treatment, more
harvest index noted with the recommended N (BI) and significantly better to other treatments.
More benefit: cost ratio registered with the FYM @10 t/ha (1.61) along with the SSNM practice
(1.65).
