Studies on the Effect of Various Levels of Nitrogenous Fertilizer Along With Blue Green Algae on Biochemical Composition of Rice Variety Pusa 1509 and Pusa Sharbati

Abstract

Nitrogen occupies a prime place in growth promotion of rice crop. Urea is most commonly used nitrogenous fertilizer which supplement rice crop with nitrogen. To study the effect of nitrogenous fertilizer along with bio-fertilizer (blue green algae) on biochemical composition of rice varieties Pusa 1509 and Pusa sharbati field experiments were performed during the period of 2018 and 2019. Nitrogenous fertilizer combined with blue green algae was applied in the experimental field and comparative observations were made on both the varieties. The interaction between nitrogenous fertilizer and bio-fertilizer treatments had a significant effect on biochemical composition of both rice varieties. Eventually, it may be concluded that the use of bio-fertilizer (BGA) in paddy plantation can save at least 40kg/ha/yr apart from the increase crop production.
