Growth and Yield of Aloe vera in Response to Different Organic Fertilizers or Manures

Aloe vera is the plant belongs to family Liliaceae. Aloe vera has acquired great commercial importance globally. In Aloe vera, researches clearly show that organic manures are more efficient compared to chemical fertilizers. This study investigated the growth and yield of Aloe vera in response to different organic fertilizers or manures. This research was laid out in Randomized Complete Block Design (RCBD) in the Crop Farm, Eastern University of Sri Lanka, as a polybag experiment with five treatments and four replicates from November 2019 to March 2020. The treatments are T1 (Control), T2 (Compost), T3 (Cow dung), T4 (Commercially available organic liquid fertilizer) and T5 (Jeewamirta). In almost all the growth and yield parameters showed a significant increase by compost (T2) and cow dung (T3) treatments compared to other treatments. In those significant parameters, between compost (T2) and cow dung (T3) treatments were shown non-significance in total leaf skin weight, total root fresh weight and leaf skin weight of largest leaf. Therefore, considering the growth parameters, yield parameters, and especially economic important parameter (gel dry weight) compost and cow dung could be recommended to enhance the growth and yield in the cultivation of Aloe barbadensis.
