Abstract

Objective: Intercropping, by increasing the number of species per unit area, is recognized as a solution to maintain and increase production in agriculture. Intercropping is a method for increasing diversity in agricultural ecosystems, which leads to increased and sustainable yield and better use of environmental resources. So that it is also referred to as an operation to economize the use of growth resources, increase production and profitability per unit area and time, and due to the similarity of this system to natural ecosystems, its ecological relationships and principles are also more effective than monoculture systems. This study was conducted to investigate the changes in yield and yield components of Aloe vera under the influence of triple intercropping in the Sistan region.
Method: This experiment was conducted as a factorial experiment based on a randomized complete block design with three replications. The first factor (methanol solution-spraying) was in 3 levels and the secondary factor (mixed cultivation) was in 9 levels. An atomic absorption spectrometer was used to measure the amount of manganese, phosphorus, and copper elements. To measure the amount of gel, the leaves of each plant were washed with water, then each leaf was cut into several parts and the gel was removed from each leaf by hand. The amount of gel for each plant was weighed using a digital scale and then the average for each plot was calculated. After counting the number of Aloe vera leaves in each plant, the leaf weight was weighed using a digital scale for each plant and then the average for each plot was calculated. To measure the number of Aloe vera leaves, three plants were randomly selected and the leaves were cut from their attachment to the plant and the number of leaves for each plant was counted and then the average number of leaves for each plant was calculated.
Results: Based on the results obtained, the interaction effect of experimental treatments on the yield and yield components of Aloe vera, as well as the absorption of copper, phosphorus, and manganese elements, was highly significant. The highest and lowest yield of Aloe vera, as well as the elements absorbed by peanuts, were obtained from the treatments of 30% by volume methanol+ 100% sour tea+ 25% peanuts+ 75% Aloe vera and 10% by volume methanol+ 100% sour tea+ 75% peanuts+ 25% Aloe vera, respectively.
Conclusions: Considering that intercropping has many advantages such as increasing diversity, reducing diseases, weeds and increasing resource use efficiency, the present study also shows the positive effect of intercropping of sour tea, Aloe Vera and peanuts compared to Aloe Vera monoculture. Methanol affects plant weight by reducing photorespiration and increasing the amount of cell swelling of plant tissues, and among the methanol treatments, the highest and lowest Aloe Vera yields belonged to the 30 and 10% methanol volume treatments.
