Effect of the Bio-stimulator Amalgerol in some Growth and Yield Properties of Two Sweet Pepper (Capsicum annuum L.) Varieties

Abstract

The field experiment was conducted during the agricultural season 2016-2017 in one of the greenhouses belonging to the Directorate of Agriculture of Basrah in Khor Al-Zubair, in order to study the effect of the bio-stimulator Amalgerol in some growth characteristics of two types of sweet pepper (Capsicum annuum L.). The trial included 18 treatments involving two types of sweet peppers: KAMAR, RIDA F1 and three concentrations of both Amalgerol (0, 2.5 and 5) ml.l-1 and the appetizer (0, 1 and 1.5) ml.l-1. The factorial experiment was implemented with Split Plot Design by Randomized Complete Block Design (RCBD) with three replicates and compared to the least significant differences test LSD at a probability level of 0.05. The main results are summarized as follows: The plants treated with 2.5 and 5 ml.l-1 of Amalgerol biomarker had a significant difference between them in each of the height of the plant, the number of leaves.plants-1, the leaf area in addition to the dry weight of the total vegetation, while the concentration of 5 ml.l-1 was superior in average fruit weight (59.44 g), fruit yield (41.95), early plant yield (233.52 g), plant yield (2.45 kg), and early productivity (3.92 ton / ha -1), in addition to total productivity of 41.15 tons.ha-1.The plants of the hybrid "Kamar" were superior in average fruit weight (61.62 g) and the early plant yield (233.40 g) in addition to the early productivity (3.921 tons.ha-1), while the hybrid plants of "Rida P1" were superior in average fruit number (45.90 fruits) and the total productivity (37.78 tons.ha-1). The interaction between the two factors of the stem and the average number of leaves. Plants-1 and the rate of the number of fruits.plants-1.
