Performance of pole sitao applied with decomposed rice straw and commercial fertilizers

Abstract

The study was conducted at Sitio Mawang Barangay Candelaria, Tapaz Capiz in the farm owned by Mr. Sulfecio G. Fundal from December 28, 2023 to April 18. 2023. The study aimed to determine the performance of pole sitao applied with decomposed rice straw and commercial fertilizers and to find out which fertilizer treatment gave the best performance in pole sitao. The experiment was composed of five treatments as follows: A- RR of commercial fertilizer (control), B- ½RR of commercial fertilizers + 5 t/ha of decomposed rice straw (DRS), C- ½ RR of commercial fertilizers + 10 t/ha of DRS, D- ½ RR of commercial fertilizers + 15 t/ha of DRS, E- ½ RR of commercial fertilizers + 20 t/ha of decomposed rice straw. Each treatment was replicated was replicated four times and was arranged in Randomized Complete Block Design (RCBD). The data was gathered, tabulated and subjected to the Analysis of Variance for RCBD. Differences among treatment means was determined using Least Significant Difference (LSD) test and was interpreted at 5% and 1 % levels of significance. In terms of growth, results of the study revealed that the length of vines were significantly influenced with the application of decomposed rice straw and commercial fertilizers. The longest vines were obtained from plots applied with ½ RR of commercial fertilizers and 10 t/ha of DRS with a mean of 2.79 meters. However, this was found similar to plants applied with ½ RR of commercial fertilizers and 5 t/ha of DRS and plants applied with RR of commercial fertilizer with a mean 2.75 meters. Similarly, plants applied with ½ RR of commercial fertilizers and 5 t/ha of DRS and plants applied with RR of commercial fertilizer were found similar with plants applied with ½ RR of commercial fertilizer + 15 t/ha of DRS and plants applied with ½ RR of commercial fertilizer + 20 t/ha DRS with a mean of 2.71 and 2.72 meters, respectively. In contrast, fresh biomass weight were not significantly influenced by decomposed rice straw and commercial fertilizer. The fresh biomass weight ranged from 2.75 to 3.38kg/plot. On the other hand, yield of pole sitao in terms of number of pods and weight of pods statistically vary, however, the length of pods did not statistically vary. In terms of number of pods, the most number of pods was obtained from plots applied with ½ RR of commercial fertilizer and 20 t/ha of DRS with a mean of 19.65. However, this was found similar with plots applied with ½ RR of commercial fertilizer +15 t/ha of DRS and plots applied with RR of commercial fertilizer with a mean of 19.02 and 18.93, respectively. Similarly, plots applied with ½ RR of commercial fertilizer +15 t/ha of DRS and plots applied with RR of commercial fertilizer were found the same with plots applied with ½ RR commercial fertilizer +5 t/ha DRS and ½ RR of commercial fertilizer +10 t/ha of DRS 18.20 and 17.93, respectively. On the other hand, the length of pods ranged from 53.3 to 55.6 cm. Finally, in terms of the weight of pods the heaviest pods were obtained from plots applied with ½ RR of commercial fertilizer and 20 t/ha of DRS with a mean of 938 grams. However, this was found similar with plots applied with RR of commercial fertilizer and ½ RR of commercial fertilizer +15 t/ha of DRS with a mean of 900 grams. These were followed by plots applied with ½ RR commercial fertilizer +5 t/ha DRS and ½ RR of commercial fertilizer +10 t/ha of DRS with a mean of 788 and 775 grams, respectively.
