Stimulated growth and correction of Fe-deficiency with trunk- and foliar-applied methanol-soluble nutrient amendments

Plants treated with nutrient-supplemented methanol showed up to 100% increases in yields when maintained under direct sunlight in desert agriculture. Plants given many applications of aqueous methanol showed symptoms of nutrient deficiency. Supplementation with a source of iron and nitrogen sustained growth, eliminating symptoms of deficiency. Major and minor nutrients were selected for solubility in methanol. Treatment through bark on stems with the formulation corrected nutrient deficiencies in citrus. Foliar application of nutrient supplemented 15% aqueous methanol increased growth and early maturation of rice when applications were made without water stress. Statistical analysis of mature panicle counts and grain yield indicates earlier maturity of methanol treated plants as compared to controls. A photographic technique was utilized to determine Chl status of rice plants.
