Comparison of Pebbles Growing Media from Agricultural Waste Materials on Productivity Growth of Melon (cv. Orange Man and cv. Galia 248) Cultivated in Greenhouse Conditions

Abstract

The objective of this research project was to compare the results from the use of pebbles growing media made from agricultural waste suitable for the growth and productivity of two cultivars, Orange Man melon and Galia 248 melon in a greenhouse. Pebbles growing media could reduce cost from the traditional material used for growing melon and have higher productivity for farmers. The experiment was divided into 5 experimental sets, namely, set that uses 100% of pebbles from agricultural waste (T1), set that uses normal planting material(coconut husk and chopped coconut coir in the ratio of2 to 1), 25 percent mixed with pebbles from agricultural waste at 75 percent (T2), 50 percent mixed with pebbles from agricultural waste at 50 percent (T3), 75 percent mixed with pebbles from agricultural waste at 25 percent (T4), and normal planting material 100 percent (T5).The research methodology is CRD, with one-way and two-way analysis of variance (ANOVA). In addition, the pair test with Scheffe’s method to compare the difference that affects fruit weight of the melon at 42 days after pollination was used. The comparison of the means and standard deviation were performed by Scheffe’s method at P ≤ 0.05 significance level. From the growth and productivity records of two cultivars melon, it was found that the experimental set that is most suitable is T2 which gave high yield of fruit width, fruit length, fruit weight and Brix value. Orange Man cultivars grown with T2 exhibited the average fruit width, fruit length, fruit weight and Brix value at 23.6±1.8 cm, 23.7±1.9 cm, 1.9±0.1 kg and 16±0.0 degrees Brix, respectively and Galia 248 cultivars grown with T2 exhibited the average fruit width, fruit length, fruit weight and Brix value at 23.2±0.8 cm, 24.4±1.2 cm, 1.9±0.1 kg and 15±0.6 degrees Brix, respectively. These results indicated that the factors of cultivar and treatment at the time of pollination are not different from each other with the statistical significance and confidence level of 95 percent compared with melons grown with T5 (normal planting material). These findings can lead to benefit farmers by reducing the cost of growing material for as much as 75 percent per time. The new material are easily manageable as well as having a long service life.
