Abstract

In recent years, biofertilizers have emerged as a promising component of the integrated nutrient supply system in Indian agriculture.  Among biofertilizers benefiting cereal crop production, blue-green algae are very important. Studies were carried out during Kharif season at the agriculture Research Station of Nawabganj Bareilly. Application of BGA @ 12.5 kg/ha in combination with 80 kg/ha as urea recorded favourable results in the two varieties Jaya and Sarju-52 and it is comparable with grain yield, nitrogen content and nitrate reductase activity in leaves at the recommended dose of 160 kg/ha. Thus, it may be concluded that further increment in nitrogen along with blue-green algae is not beneficial in rice crop and it can save at least 40 KgN/ha/year with increased yield.
