THE EFFECT OF AGRICULTURAL ENVIRONMENT AND PLANT DENSHTY ON THE GROWTH AND PRODUCTION OF Allium sativum L. GARLIC.

Abstract

The study was conducted at the Department of Horticulture Field / Faculty of Agriculture / Diyala University agricultural season 2014-2015. Where the study was six agricultural communities and three plant densities influence the growth and production of garlic Allium sativum L. of the National product. The study included 18 treatment is a consensus among the six agricultural communities are soil (control) and peat moss mixture peat moss with sawdust ratio of 1: 2 and peat moss with sand ratio of 1: 2 and composting cows with sawdust ratio of 1: 2 and composting cows with soil by 1 : 1 and three plant densities are 40,80,120 plant. m -2 and studied the characteristics of plant height and number of leaves and diameter neck of the bulb and the rate of head weight and the weight of the bulb the overall and winning and the ratio soluble solids in the lobes can be summarized results The study also follows: - The study results showed superiority amid peat moss with sawdust morally in my recipe plant height and total winning of the plant while the superiority of Amidst peat moss in my recipe number of leaves and the ratio soluble solids at all circles while outweigh amid peat moss with sand in diameter onion recipe neck. As for the transactions plant density showed a plant density of 120 plant.m -2 significant superiority in my recipe plant height and winning the overall of the plant gave the plant density while 40 plant.m -2 morally superior to the rest of the adjectives densities in the head and the weight ratio of soluble solids. Interference has affected the Amidst peat moss of sawdust and plant density 120 plant .m -2 morally in increasing recipe plant height, and gave the t peat moss treatment of overlap between the soil and plant density 120 plant .m -2 holds the highest total of garlic while the overlap between Amidst peat moss and plant density exceeds 40 plant .m -2 In my recipe weight of the head and the percentage of soluble solids.
