Effect Of Different Levels Of Nitrogen On Growth And Yield Attributes Of Different Varieties Of Basmati Rice Oryza Sativa L.

ABSTRACT A field trail was conducted during rainy season at crop research farm Allahabad agriculture institute Deemed university to evaluate the effect of different levels of nitrogen on growth and yield attributes of different varieties of Basmati Rice Oryza Sativa L.. The varieties which was evaluated were Haryana Basmati-1 Basmati -370 and Pusa basmati -1 under three different fertility levels viz 100 120 and 140 the combinations was replicated three times in factorial 3 RBD. The varietal trial indicates that Pusa Basmati- 1 at nitrogen -120 level was significantly different from all the parameters measured which include plant height number of tillershill dry weight length of panicle number of filled grains panicle straw yield biological yield harvest index benefit cost ratio and grain yield of 4.66 tonnes hectare at level nitrogen level-120 3.10 tons hectare at nitrogen level -120 were maximum and minimum in Pusa basmati -1 and Basmati -370 respectively .
