Abstract
The escalating demand for sustainable agricultural
practices has intensified research into biological alternatives to conventional
chemical fertilizers. This study investigates the synergistic effects of
co-inoculation with phosphobacteria and potash-solubilizing bacteria (PSB) on
the growth and yield of lettuce (Lactuca sativa L.). While phosphorus (P) and
potassium (K) are essential macronutrients for plant development, their low
bioavailability in soil presents a significant challenge. Conventional methods
of nutrient supplementation, primarily through synthetic fertilizers,
contribute to soil degradation, environmental pollution, and increased
production costs. This research hypothesizes that the combined action of
phosphobacteria, which convert insoluble soil phosphates into a plant-available
form, and PSB, which release fixed potassium, will significantly enhance
nutrient uptake and promote superior plant growth compared to
single-inoculation treatments or un-inoculated controls. A greenhouse
experiment was conducted using a randomized complete block design, evaluating
five treatments: un-inoculated control, single inoculation with
phosphobacteria, single inoculation with PSB, co-inoculation with both
bacteria, and a chemical fertilizer control. Data were collected on key
parameters, including plant height, leaf count, fresh and dry biomass, and
nutrient content of plant tissues. The results are expected to demonstrate that
co-inoculation is a highly effective, eco-friendly, and economically viable
strategy for improving lettuce cultivation, offering a promising approach to
reduce reliance on synthetic inputs while maintaining high yields.
