DIAGNOSIS OF NUTRITIONAL CONSTRAINTS OF AZOLLA SPP. TO ENHANCE THEIR GROWTH UNDER FLOODED CONDITIONS OF SALT AFFECTED SOILS NAIMA HAMID, SIKANDER ALI, KAUSER A. MALIK AND FAUZIA Y. HAFEEZ Abstract: A green house experiment was conducted to know the nutritional constraints
of Azolla for enhancing its growth under flooded conditions and
select the best ones for its use as biofertilizer in rice-wheat cropping
system. Among the tested nutrients viz; phosphorus, iron and zinc, phosphorus
was found to be the major limiting nutrient for plant growth. A.
pinnata var. pinnata and hybrid Azolla Rong Ping
gave better growth, hence can be used as biofertilizer in rice-wheat
cropping system.
