دور المغذيات العضوية في نمو وحاصل نبات الحلبة Trigonella foenum-graecum وتراكم بعض المركبات الفعالة
Abstract
The experiment was applied in College of Agriculture,University of Wasit. The aim of study was to estimate the effect of organic nutrients on the growth and yield of fenugreek plant. The experiment was conducted within a randomized complete block design (RCBD) with three replicates and the averages were compared according to the L.S.D. test at a probability level of 5%. The experiment included 6 treatments, which are adding organic nutrients Disper Humic to the soil at a level of 3 kg/ha-1 and King Life Fruit spraying on the leaves at a concentration of 2 g/L-1 either alone or in combination with half the recommended chemical fertilizer. The first addition of both nutrients was 20 days after planting, which is the same period between one addition and another. As for the chemical fertilizer, the first addition was 20 days after planting and the second was a month after the first addition. The results were compared with the chemical fertilization treatment and the treatment without fertilization.
The results of the experiment showed that the T2 treatment (100% chemical fertilizer) was superior in most of the characteristics of vegetative growth, yield and its components. This is obvious because chemical fertilizers are rich in mineral elements, quickly dissolve and more readily absorbed, but they are fertilizers that have health and environmental effect. Therefore, the focus of our research aims to find a fertilization program that is friendly to the environment and human health and gives results close to the results of chemical fertilizer. Our research showed that the T6 treatment (adding King Life Fruit + Disper Humic in three batches + 50% chemical fertilizer). The results close chemical fertilization with insignificant differences for most of the studied characteristics, but it was superior in the characteristic of Trigonelline compound accumulation.
