INFLUENCE OF Grow Peat ON GROWTH, YIELD AND CHEMICAL COMPOSITION OF FRENCH BEAN

January 10, 2024

Soil application of potassium humate, significantly, reflected positive influences on canopy dry weight and leaf area plant. Number and weight of green pods plant, total green pods yield fed, number of dry pods plant, weight of 100 dry seeds, dry seeds yield plant and fed were positively responded to application of potassium humate, while, average green pod weight did not respond. Leaf total chlorophyll, N, P and K contents went, significantly, forward due to application of potassium humate. Leaf Cl and Na contents were, truly, depressed due to application of potassium humate, orderly. Significant increments in protein and carbohydrates content in dry seeds were observed as a result of addition potassium humate, consecutively.

The improving effect of potassium humate

up to a particular level on green pods yield and its components can be discussed on

the ground that potassium humate capable to increase availability, absorption and uptake of nutrients and augmented photosynthetic pigments which improve the plant growth with an eventual increase in green pods yield and its components. Our results are in accordance with the results of who clarified that addition of humic acid, through drip irrigation system, to snap bean plants, significantly, increased number and weight of green pods plant and total green pods yield fed. Likely, reported that increasing foliar application of humic acid up to a particular concentration accompanied with progressive increase in green pods yield of snap bean. Similar results were reported by on common bean, on pea

The study on the impact of humic acids on the growth of French beans yields compelling results, highlighting the positive influence of these organic compounds on plant development.

The observed accelerated growth and increased yield of French beans underscore the efficacy of humic acids in stimulating physiological processes in plants.

One key factor is the ability of humic acids to improve soil structure, facilitating better root penetration and nutrient absorption. This, in turn, leads to more active plant life, enhanced root formation, and increased resistance to stressful conditions.

Furthermore, the improved plant physiology observed may also be attributed to the increased content of micronutrients in the soil, resulting from the interaction of humic acids with mineral components. This phenomenon is crucial for optimal growth and the formation of healthy plants.

Thus, our research confirms that the application of humic acids contributes significantly to the noticeable improvement in the growth and yield of French beans, making them an appealing means to enhance the productivity and resilience of agricultural crops.
