The present invention relates to synergistic plant growth stimulating composition of potassium salt of organic acids with nitrogenous compounds. The composition of the present invention combats both biotic and abiotic stress, resists waterlogging stress, eliminates ROS thereby alleviates oxidative damages and enhances the yield and quality produce of the plants/crops.
The plant growth and development as well as productivity of the crops, fruits, flowers etc. are known to be regulated by mineral components, growth hormones and small molecules that signal for expression of genes which enhance the level of plant productivity. The traditional methods of improving the plant growth include supplementing the soil or the plant with nitrogen, phosphorous, potassium (NPK) nutrients and other micro nutrients.
The present traditional methods are insufficient in the wake of growing pollution, environmental changes, rapid depletion of soil quality due to excessive use of fertilizers and other abiotic stresses such as increase level of salts in the soil, drought, cold, heat and heavy metal stresses, waterlogging stress and biotic stress on plants by living organisms specially viruses, bacteria, fungi, nematodes, insects, arachnids and weeds. These agents directly deprive their host of its nutrients can lead to death of plants. Biotic stress can become major problem because of pre- and postharvest losses.
Potassium is normally required by a growing plant to stimulate early growth, to increase protein production, and to activate beneficial enzyme and hormone systems within the plant which impact the plant's ability to withstand biotic and abiotic stress.
The typical potassium sources used are the inorganic potassium salts such as potassium chloride, potassium magnesium sulfate, potassium nitrate and potassium sulfate. The use of inorganic potassium salts, however, is found to have damaging effect on the environment.
Fertilizers are now provided with potassium derived from environmentally friendly organic potassium source.
WO2017/040938 provides fertilizer comprising soluble nitrogen, a phosphate source and a potassium source, wherein, the potassium source is an organic potassium source, animal manure, carboxylic acid salts of potassium, potassium silicate and combinations thereof. The nitrogen source is selected from the group consisting of urea, nitrate, triazone urea, ammonia, ammonium salts, ammonium hydroxide, amino acids, fish meal or extract, compost extract, kelp extract, shrimp extract, shellfish extract, and combinations thereof. The carboxylic acid salt of potassium is selected from potassium formate, potassium acetate, potassium propionate, potassium butyrate, potassium valerate, potassium hexanoate, potassium oxalate, potassium malonate, potassium succinate, potassium glutarate, potassium adipate, potassium lactate, potassium malate, potassium citrate, potassium glycolate, potassium tartrate, potassium glyoxylate, potassium pyruvate, and combinations thereof.
Plant hormones such as auxins, cytokinins, gibberellins, ethylene and abscisic acid greatly improve plant vigor, promote growth of roots and shoots and reduce stress.
