Growth and Yield of Organically Grown Bush Snap Beans (Phaseolus vulgaris) Intercropped in Between Satsuma oranges

Abstract

Two varieties of bush snap beans were evaluated as intercrops on Satsuma oranges applied with five different organic fertilizers at BSU pomology project. Results showed that earlier development of harvestable pods were observed on Cv. Sablan bush beans with a mean of 17.27 days; while Cv. Snap Black bush beans produced heavier pods per plant weighting 27.93 g with heavier marketable pods per plot at 1, 016 g; and heavier computed yield per hectare at 6.78 tons. Earlier harvesting of pods were promoted with the application of vermicompost and siglat at 10t/ha for both bush bean varieties after 16.83 days from 1cm pod setting. Plants applied with Siglat fertilizer at 10 t/ha resulted to taller plants at 52.17 cm; heavier marketable pods per plant at 30.8 g; heavier marketable pods per plot at 1,205 g; heavier marketable seed yield per plot at 304.0 g; heavier computed pod yield per hectare at 8.03 tons; and heavier seed yield per hectare at 2.20 tons. The longest pods of bush beans were obtained with the application of 20 t/ha alnus compost and 10t/ha BSU Growers compost with comparable means of 14.00 and 13.25 cm, respectively. Lower non-marketable pods per plot were obtained from plants applied with 2 tbsp Nextgen humic acid per 16 L of water and 10 t/ha vermicompost with comparable means of 44g and 36g, respectively. On the other hand, lower non-marketable seeds per plot were obtained from plants applied with BSU Growers compost at 10t/ha with a weight of 12.7 g. Heavier weight of 1, 000 seeds were obtained from plants applied with 10t/ha BSU Growers compost and 10t/ha siglat fertilizer with a comparable mean of 241.0g and 238.9 grams, respectively. Highly significant interaction effects were obtained on the days from fruit setting to first harvest; pod length at harvest; weight of non-marketable pods per plot; marketable seed yield per plot; weight of 1000 seeds; and computed seed yield as affected by the bush beans varieties and kinds of organic fertilizers. The application of vermicompost and siglat fertilizer at 10 t/ha to Cv. Sablan hastened earlier harvesting. While the application of alnus compost at 20 t/ha to Cv. Snap black produced the longest pods compared to the shortest pods harvested from plants applied with nextgen Humic acid. Cv. Sablan produced its longest pods with the application of BSU Growers compost at 10 t/ha while the shortest pods were gathered in plants applied with of Nextgen humic acid. The application of vermicompost at 10 t/ha to Cv. Snap black produced lower non-marketable pod weights; while with the application of siglat fertilizer; higher non-marketable pods were harvested per plot. On the other hand Cv. Sablan with the application of next gen humic acid yielded lower non- marketable pods harvested but with the application of BSU Growers compost higher weight of non-marketable pod were obtained per plot. The application of siglat fertilizer at 10 t/ha to both varieties had produced the highest marketable seed yield per plot in which Cv. Snap black had a 329.3 g seed weight while Cv. Sablan had 278.7 g seed weight. However, the application of vermicompost at 10t/ha and Next gen humic acid at 2 tbsp/16L made Cv. Snap black produce the lowest weight of marketable seeds per plot. Likewise, Next gen humic made Cv. Sablan produce the lowest weight of marketable seeds per plot. The application of BSU Growers’ compost at 10 t/ha on Cv. Sablan promoted the production of heavier seeds. Snap black had its highest weight of 1000 seeds with the application of siglat fertilizer at 10t/ ha. Lowest weight of 1000 seeds on Cv. Snap black was noted when applied with Nextgen Humic acid while the application of alnus compost at 20 t/ha and vermicompost at 10 t/ha resulted to the lowest weight of 1000 seeds in Cv. Sablan. The highest computed seed yield per hectare on both varieties were taken when both were applied with siglat fertilizer at 10 t/ha. Cv. Sablan produced its lowest computed seed yield per hectare with the application of nextgen humic acid at 2 tbsp/16 L. On the other hand, application of alnus compost at 20 t/ha and next gen humic acid at 2 tbsp/16 L caused Cv. Snap black to produce the lowest seed yield per hectare. The highest return on investment (ROI) was obtained from plants fertilized with siglat. Black snap variety had the higher return of investment (ROI) with 122.89 % while for Cv. Sablan the ROI 101.76 %.
