Abstract:
Rice-wheat is the most predominant cropping system, occupying in India, especially in North India. Under the scenario emphasis are being given on the resource conservation technologies, hence, it has become imperative to develop technologies that are specific to the particular field or particular set of resources. Therefore, the present investigation was conducted for two years from <em>Rabi</em> (wheat) season of 2015-16 through <em>Kharif</em> (rice) season of 2017 at Experimental Farm of Rice and Wheat Research Centre, Malan. The experiment consisted of 10 treatments combinations comprising five nutrient management practices in wheat <em>i.e. </em>recommended fertilizer dose (120:60:30 kg ha<sup>-1</sup> NPK) with top dressing of nitrogen after irrigation; recommended fertilizer dosewith top dressing of nitrogen before irrigation; fertilizer dose as recommended by software Nutrient Expert – Wheat (125:45:78 kg ha<sup>-1 </sup>NPK) with top dressing of nitrogen before irrigation; Nutrient Expert – Wheat guided fertilizer dose (70% nitrogen recommended by software and rest with green seeker technology) with top dressing of nitrogen before irrigation and N-rich plot which received 150% of recommended nitrogen with top dressing of nitrogen before irrigation with two tillage options <em>i.e.</em> conventional tillage and zero tillage tested in strip plot design, replicated three times. Results revealed that tillage options had no significant effect on growth indices of wheat while conventional tillage significantly increased the growth indices of rice over zero tillage. Among nutrient management practices, N-rich plot in which 150% of recommended nitrogen was added produced significantly taller plants and higher dry matter accumulation in wheat. However, plant height and dry matter accumulation of succeeding rice was not significantly influenced by nutrient management practices.
