abstract
The study was conducted at New Developmental Farm (N.D.F), The University of Agriculture, Peshawar, Pakistan, during the year 2015 to determine the role of insect pollinators on pea yield, seed weight and mass in Randomized Completely Block Design (R.C.B.D). The experiment was comprised of two treatments i.e. Pea plants in caged condition (T1) and pea plants in open condition (T2), which were replicated thrice. In each replication one treatment was caged with nylon cloth having mesh no. 49/cm2 before flowering stage. Pea pods were picked five times in the whole fruiting season and were taken to laboratory, to determine the yield, hundred grain weight and mass. The yield was converted to kg/ha. Higher yield, weight and mass of 2538.8kg/ha, 55.34grams and 53.3ml/100grains respectively of peas were found that were collected from the treatments of open condition as compared to the treatments of caged condition.
