Abstract
A pot experiment was conducted at the Agric. Exp. Station of El-Mansoura Univ. during the winter season of (2013/ 2014); to investigate the effect of some amendments on calcareous soil using sugar peas (Pisum sativum var . macrocarpon) variety of "mangetout"" ,type (Snow wind). Thirteen treatments were arranged in a complete block design, which were the simple possible combination between four treatments of soil amendments application (Magnetite (100, 200 and 300 kg fed-1), Sulphur (200, 300 and 400 kg.fed-1), Humic acid (5, 7 and 9 kg fed-1) and Fulvic acid (2, 3 and 4 kg fed-1)) compared with control treatment. Each treatment was replicated three times. The highest mean values of pea plants as fresh, dry weight (g), plant height (cm) and No. of leaves plant-1 also NPK% and its uptake mg plant-1 in plant foliage, N, P, K% and its uptake g plant-1, Fe ppm in pea seeds were significantly affected after 50 and 90 days during the season and obtained with using magnetite as material amendment at the rate of 300 kg fed-1 followed by using soil humic acid at the rate of 9 kg fed-1 compared with the other treatments. The same results were obtained with yield parameters (weight of 1000 seeds (g), fresh pods weight (g), fresh pods length and pea yield (g plant)-1 and seed quality (Total carbohydrates, Total sugar % and V.C (mg 100g) -1 which recorded the highest values with adding magnetite at the rate of 300 kg fed-1. In plant foliage, the highest values of Fe ppm was recorded with using magnetite as a source of iron at the rate of during both stages followed by using humic acid. As for Zn and Mn ppm recorded, the highest mean values with using fulvic acid at the low rate 2kg fed-1 comparing the all parameters with the control which recorded the lowest mean values of Fe, Zn and Mn ppm of plant foliage after. This trend was observed during both stages after 50 and 90 days.
