Abstract
Plastic house trial was conducted at Department of Horticulture and Landscape, College of Agriculture, Abu-Ghraib, the alternative location of Anbar University during fall season of 2016 to investigate the effect of indole acetic acid as foliar spray at 50 mg l-1 and bat guano as soil application at 10 and 30 gm per plant on growth and yield for medicinal pumpkin. Consequently, Treatments were randomly distributed as one way factor using RCBD with three replicates. Results pointed that bat guano applied with 10gm per plant was superior in stem length of 5.42m, nodes per stem of 54.97 nodes stem-1, leaf area of 389 Dcm2, chlorophyll content of 94.91 SPAD and leaves no. of 92.30 leaves plant-1. Furthermore, bat guano application gave the best average of fruit no of 14.00 fruit 2 m-2, seeds per fruit of 527.30 seed fruit-1, seeds weight per fruit of 77.80 gm, 1000 seeds weight of 282.90 gm and fruit weight of 4.544 kg fruit-1. Moreover, it reduced days upto first male flower emergence of 43.27 days, the arrangement of node that first male flower appearance of 2.13 and days upto first female flower emergence of 26.57 days. It also increased female flower no of 6.33 female flower and female sexual ratio of 0.81%. Finally, it reduced male flower no. of 7.77 male flowers.
