Paper-V BOT S05 Skill Development BIOFERTILIZERS Credits: 05 (Theory 70+ Practical 30) Full Marks: 100 Time: 03 Hrs. In all nine questions of equal value will be set, out of which a student shall have to answer five questions. Q.no. 1 will be compulsory, consisting of seven very short answer type questions (each of two marks) covering the entire syllabus and the candidates are required to give their answers in maximum 50 words. General account the microbes used as biofertilizer Rhizobium – – isolation, identification, mass multiplication, , Actinorrhizal symbiosis. isolation and mass multiplication carrier based inoculants, Azospirillum: – associative effect of different microorganisms. characteristics Azotobacter, crop response to inoculum, maintenance and mass Azotobacter – multiplication. Cyanobacteria (blue green algae), and Azolla Anabaena azollae association, nitrogen fixation, factors affecting growth, blue green algae and in rice cultivation. Azolla Mycorrhizal association, types of mycorrhizal association, taxonomy, occurrence and distribution, phosphorus nutrition, growth and yield – colonization of VAM isolation and inoculum production of VAM, and its – influence on growth and yield of crop plants.
