Data on growth and production of (Aloe vera L.) treated by different levels of vermicompost and nitrogen fertilizer

Data on the effect of vermicompost and nitrogen on growth and production of Aloe vera, an experiment was carried out in 2015–2016 at Faculty of Agriculture of Islamic Azad University of Khoy. This experiment was arranged as factorial, based on RCB design with four replications. Treatments were 4 levels of vermicompost (Control, 75, 150 and 200 gr per pot) and four levels of nitrogen fertilizer (N1: control, N2: 500, N3: 1000, and N4: 1500 mg per pot). Nitrogen fertilizer was split into three stages (8 leaves, before suckering and the beginning of formation suckers). Traits investigated such as plant height, number of leaves, stem diameter, number of suckers, number of leaf sucker, sucker weight, sucker height and total biomass. This article present data regarding the application of 150 g of vermicompost and 1000 mg of nitrogen and 200 g of vermicompost and 1500 mg of nitrogen on the characteristics of sucker. Therefore, data on simultaneous application of vermicompost and nitrogen fertilizer in Aloe vera cultivation as an important role in the production and enhancement of sucker and plant yield mentioned.

Therefore, data on simultaneous application of vermicompost and nitrogen fertilizer in Aloe vera cultivation as an important role in the production and enhancement of sucker and plant yield mentioned.   Table 2. Analysis of variance of vermicompost and nitrogen on studied traits in Aloe vera are present in Table 3. Comparison of mean vermicompost and nitrogen treatments on the traits of Aloe vera are shown in Table 4. Comparison of the mean of interaction between vermicompost and nitrogen on studied traits in Aloe vera are present in Table 5. Simple correlation coefficients of the traits studied in the Aloe vera are shown in Table 6. Interaction between vermicompost and nitrogen fertilizer on plant height in Aloe vera are depicted in Fig. 1 The Effect of Vermicompost and Nitrogen Fertilizer on Number of sucker in Aloe vera are shown in Fig. 2. The Effect of Vermicompost Fertilizer and Nitrogen on Total Biomass in Aloe vera are depicted in Fig. 3.  ns, * and **: Non-significant and significant at the 5 and 1% levels of probability, respectively. In each column, the same letters indicate that there is no significant difference between the meanings (LSD test).

Experimental design, materials, and methods
An experiment was conducted to evaluate the effect of vermicompost and nitrogen on growth and production of Aloe vera. Treatments were 4 levels of vermicompost (Control, 75, 150 and 200 gr per pot) and four levels of nitrogen fertilizer (N1: control, N2: 500, N3: 1000, and N4: 1500 mg per pot) [1,2]. Nitrogen fertilizer was split into three stages (8 leaves, before suckering and the beginning  of formation suckers). In June, uniform suckers with a size of 18 to 20 cm were randomly selected and transferred to the greenhouse, and in pots with capacity of 20 kg of soil was planted. Before planting vermicompost treatments were added to pots and completely mixed with the soil [3]. The greenhouse temperature for the growth of the Aloe vera was 28°C/day and 22°C at night uniformly. Plants were irrigated on the crop capacity. The greenhouse experiment was conducted at the Faculty of Agriculture of Islamic Azad University of Khoy in 2015-2016. This experiment was arranged as factorial, based on RCB (Randomized Complete Block) design with four replications. At the end of the plant growth period, traits such as plant height, number of leaves, stem diameter, number of suckers, number of leaf sucker, sucker weight, sucker height and total biomass were measured [4,5]. Traits such as number of leaves and height of plant were measured by a ruler from the crown (from leaf to leaf tip), for measuring the stem diameter, a digital caliper was used and reported as a centimeter, to measure the traits suckers, suckers were separated from the mother plant and their number was counted and then the height of the suckers, weights of sucker, number of suckers leaves and total biomass of the plant were measured.

Statistical analysis
Analysis of variance of the data was carried out using SAS software. LSD test was applied to compare means of each trait at p r 0.05. EXCEL software was used to draw figures.
