Abstract

The aim of the study was to determine the viability of kidney bean seed varieties Inerie is organic priming with different concentrations of young coconut water. This research was conducted in the Horticulture laboratory and screen house in the month of October 2021. The research design used was a Randomized Design Complete with 7 concentration treatments which were 4 repeated. The treatment used is the concentration of young coconut water that is 0% (control), 10%, 20%, 30%, 40%, 50%, and 60%. The results showed that a concentration of 30% young coconut water as organic priming can increase seed germination (83.00%) and seed growth speed (22.02%/day), and a concentration of 10% can increase seed growth synchrony (81.00%).Key Words:  Invigoration, Kidney Bean, Organic Priming, Young Coconut Water

Abstract

The research objective  to examine the best concentration of BioBoost and MKP, as well as their interaction, in enhancing the production of kidney beans of the Inerie variety in lowlands. The study was designed using a Factorial Randomized Complete Block Design with treatments including BioBoost concentrations (10 ml/l, 15 ml/l, 20 ml/l, 25 ml/l) and MKP concentrations (5 g/l, 10 g/l, 15 g/l). The data were analyzed for variance and tested with Honestly Significant Difference at 5%. The research results indicate that 1) BioBoost at 25 ml/l resulted in the lowest number of empty pods (1.67 pods), the highest number of seeds per plant (44.61 grains), the heaviest seed weight per plant (15.80 g), and the heaviest weight of 100 seeds (36.29 g), 2) MKP at 15 g/l resulted in the highest number of seeds per plant (40.14 grains), the heaviest seed weight per plant (14.30 g), and the heaviest weight of 100 seeds (34.61 g), and 3) the interaction between BioBoost concentration at 25 ml/l and MKP at 5 g/l  was the best for the highest number of filled pods (15.89 pods) and the lowest number of wrinkled seeds (0.75 grains).

Abstract

Kidney beans (Phaseolus vulgaris), belonging to the Leguminosae family and classified as C3 plants, typically exhibit slower photosynthesis and lower biomass production under high light intensity and hot temperatures. To overcome these limitations and enhance photosynthetic efficiency, external stimulation of plant physiological processes is crucial. One promising approach involves the application of Photosynthetic Bacteria (PSB), known for their independent photosynthetic capabilities. This study aimed to evaluate the impact of PSB application at various growth stages on leaf chlorophyll content and the yield of 'Inerie' variety kidney beans, and to identify the optimal application timing. A Randomized Block Design (RBD) was employed, comparing seven PSB application treatments: a control, single applications at the exponential growth, flower initiation, and pod formation stages, and combined applications (exponential + flower initiation; exponential + pod formation; flower initiation + pod formation; and exponential + flower initiation + pod formation). The results indicated that PSB application at different growth stages significantly influenced both chlorophyll content and kidney bean production. The optimal application time was identified as the flower initiation phase, which significantly increased chlorophyll a content to 8.51 mg/g, total chlorophyll to 14.69 mg/g, and enhanced yield components, resulting in 22.22 pods per plant, 63.06 seeds per plant, and a seed weight of 24.44 g.
