Abstract:
The experiment was conducted at Mustard Oil Field, Agriculture farmer filed Naseerabad, Balochistan in a Randomized Complete Block Design (RCBD) having net plot size of 5 x 1.2 m with three replications to monitor the population dynamics of sucking insect pests on mustard. Five mustard varieties i.e. UCD-1204, NMT-9, Canola 2, Nawab Shah 24and P-25 and was screened to evaluate the relative resistance against sucking insect pests. The monitoring of the sucking insect pests was started right from 15th December, 2020 to 06th March, 2019. The population buildup of each sucking insect pest was monitored at weekly interval. Highest infestation of whitefly (0.98±0.29 nymphs per plant) was recorded for Nawab Shah 24followed by P-25 (0.92±0.26 nymphs per plant), NMT-9 (0.89±0.25nymphs per plant) and Canola 2 (0.82±0.22 nymphs per plant), while lowest infestation (0.77±0.21 nymphs per plant) was observed for UCD-1204. Highest infestation of thrip (3.20±0.78 nymphs per plant) was recorded for Nawab Shah 24followed by P-25 (3.08±0.75 nymphs per plant), NMT-9 (2.97±0.70 nymphs per plant) and Canola 2 (2.93±0.6 nymphs per plant), while lowest infestation (2.50±0.57 nymphs per plant) was observed for UCD-1204. Overall mean highest population of jassid (0.74±0.20nymphs per plant) was recorded for Nawab Shah 24followed by P-25 (0.60±0.30 nymphs per plant), Canola 2 (0.59±0.15 nymphs per plant) and NMT-9 (0.56±0.16nymphs per plant), while lowest infestation (0.19±0.05 nymphs per plant) was observed for UCD-1204. Highest infestation aphid (21.80±10.28 nymphs per plant) was recorded for Nawab Shah 24followed by P-25 (20.78±10.10 nymphs per plant), NMT-9 (20.48±9.64 nymphs per plant) and Canola 2 (18.85±9.07nymphs per plant), while lowest infestation (18.27±9.04 nymphs per plant) was observed for UCD-1204. Maximum crop yield (1850.53 kg plot-1) was recorded for UCD-1204 followed by NMT-9 (1560.2 kg plot-1), P-25 (1540.5 kg plot-1) and Canola 2 (1520.3 kg plot-1) and the minimum crop yield (1498.8 kg ha-1) was noted for Nawab Shah 24mustard variety. maximum infestation of whitefly, thrip, jassid and aphid was observed for variety 'Nawab Shah' and minimum was observed for variety 'UCD-1204'.
