Abstract:

The effect of potential cyanobacterial N2 fixer (Anabaena cylindrospermoides) was studied on growth parameters, root architecture and photosynthetic pigments of basmati rice (variety : PB-1121) grown in pots with soil as rooting medium under controlled conditions of National Phytotron Facility of ICAR-IARI, New Delhi. The treatments used were as T1: 100% N, T2: 75%N, T3: 75%N + N2 fixer, T4: 50% N, T5: 50% N + N2 fixer.  In general, treatment T3 showed enhanced total plant length, root length, total fresh weight, root and shoot fresh weight as well as dry weight of plants as compared to treatment T1. However, the treatment effect was non-significant for root and shoot dry weight as well as number of leaves. Root architecture also altered with treatments and total root length, surface area and root volume in under treatment T3 were at par with the observations under treatment T1. Chlorophyll a and chlorophyll b were statistically similar under treatments T3 and treatment to T1, whereas, total carotenoids were not influenced by different treatments under study. The influence of cyanobacterial inoculant could be attributed to the nitrogen fixing property with the potential of extracellular ammonia release and production of Indole Acetic Acid by the strain used. Further testing under outdoor conditions will help to assess its efficiency and exploitation in integrated nutrient management of rice crop.
