The study was conducted to evaluate the use of agricultural wastes as useful growing media for pomelo (citrus grandis) as compared to fertile soil. This agricultural research aims to determine the higher-value uses of agricultural wastes such as animal manure, rice hulls and bran by using it as media for growth of pomelo. The scope included only the utilization native duck manure, fresh rice ban, fresh rice hulls and parboiled rice hulls.
The process involves the preparation of pomelo seedlings, preparation of growing media, transplanting method, sustaining growth and monitoring growth of pomelo seedlings in terms of height of the plant and the number of leaves.
The pomelo seedlings were observed to survive during the experimentation period. However, the growth varied from one medium to another. To compare the growth rate of pomelo seedlings in agricultural wastes and soil, the t-test was used.
It is determined by the mean sample of growth of pomelo plant in the growing to media as labeled T1 to T3 as compared to a standard mean sample, that of the soil, T4.
The computed value of t at p>. 05 is 1. 23 and 2. 47 less than the critical value 2. 920. This result revealed that there is no significant difference between soil and animal manure-parboiled rice hulls as growing media of pomelo plant.
While the greater tcomputed value of T1 and T2 divulged that there is a significant difference between the growth rate of pomelo in the soil and in fresh rice bran (T1) and hulls (T2). This proves that agricultural wastes can be used as growing media for pomelo seedlings. This also affirms that agricultural wastes can help plant breeders to lessen expenses in terms of growing media necessary for plant growth.
