Effect of Irrigation, Sowing Depth and Seed Cover on the Growth and survival Seeds (Pistacia Atlantica Desf.) Koushcan Zanjan Nursery
Wild pistachio forests in terms of the harvesting of various types of products and in terms of energy production and fuel wood are severely exposed to destruction. One of the effective methods for preserving and developing these forests is helping them with artificial regeneration. The purpose of this study was the most appropriate Irrigation, sowing depth and seed cover for seed of Wild pistachio in Kushkan nursery of Zanjan province. For this purpose experimental design in a completely randomized at three different sowing depth treatments including (0-3/99), (4-6.99) and (7-8 cm) and four seed covers including (50% soil + 50% manure) (50% soil + 50% sand), (50% soil + 50% zeolite) and (50% manure + 50% (soil, sand and zeolite)) and two irrigation including with irrigation and without it with six replications designed and collar diameter, plant height, root height, stem length to root, root and shoot dry weight ratio and percent survival was measured. Then, for comparing the mean and the effect of treatments on each mean, the analysis of variance, Duncan test and t-test were used. ANOVA test showed that different treatments of irrigation, sowing depth and seed cover had significant effect on characteristics measured of planting. The best result for seeding Baneh considering the interactions of the studied treatments was at surface depth (0-3/99 cm) with (half manure + half (soil, sand and zeolite)) and with irrigation.
