abstract
The study was carried out at Pulse Section, Agriculture Research Institute, Tandojam, during Rabi season 2016. The highest infestation of aphid was observed in 3^rd week of Jan. on C-612 (21.66) per plant followed by Sanyasi (6.66), DG-92 (6.00) and DG-89 (5.66). Similarly minimum infestation of aphid was observed during last week of Nov. on Sanyasi variety (2.00) followed by DG-92 (2.33), DG-89 (2.33) and C-612 (3.00). The data further showed the overall mean population of aphid on chickpea varieties i.e., C-612 (9.99 ± 6.31) followed by DG-92 (4.15 ± 1.06), DG-89 (3.92 ± 1.08) and Sanyasi (3.88 ± 1.25). There was significant difference (p<0.05) in population fluctuation of aphid on different chickpea varieties and observation dates. Maximum aphid population (9.91) was recorded on 3^rd week of Jan., whereas minimum aphid population (2.64) was observed on last week of Nov. 2016. The aphid population significantly (p<0.05) higher on C-612 chickpea variety compared to DG-92 and DG-89 varieties and lowest aphid population was noted on Sanyasi variety.
