TECHNICAL FIELD
The present disclosure is related to the technical field of Agrochemicals. More particularly, the present disclosure provides a synergistic combination, a process to prepare it and a method of delivery to plants for their efficient and economical growth.
BACKGROUND
Plants have always remained to every civilization as the primary source of life. They need water, sunlight, air and soil for its growth. The leaf part of the plant is a "process house" where photosynthesis takes place and food in the form of cellulose/carbohydrates/ protein/ fat is produced. The efficiency of photosynthesis depends on the availability of various essential nutrient(s) to achieve superior growth and productivity. Generally, plants growing on the land pick up nutrients from the soil and those growing in water pick it up from the water. If the nutrients are not present in the soil/water, or in a biologically available form then deficiencies are caused to plants, leading to loss of crop yield. Promoting plant growth is a desirable way to improve plants and their cropping. Over a period of time there were various compositions and methods adopted to promote the growth of plants [US Patent Nos 3873296, 3738822, 3742002 and 4960452]. Growth promotion by improving soil fertility is one of the most common tactics used to augment the growth of plants. However, such a tactic has not always helped in having economical and efficient plant growth, reason being that there is lack of availability of essential nutrients to all parts of the plants due to the impact of various factors namely soil pH, humus content etc.
Another known method of supplying nutrients to plants is by "Foliar Feeding". This is a technique where feeding of plants is done by applying liquid fertilizer directly to their leaves. Currently, this technique is limited to feeding inorganic or chelated nutrients. Foliar feeding of inorganic nutrients forms chalk like precipitate over the surface of leaves and there by creating impediment for absorption of essential nutrients. Additionally, it may also cause leaf bums, closing of pores or stomata etc. A mix of all inorganic micronutrients is not possible as all these get oxidized and precipitated out of the solution. Individual chelated nutrients have to be separated and then sprayed. Macronutrients like Urea, phosphate. Calcium etc cannot be sprayed in combination with all EDTA chelated micronutrients due to interaction, ion interference, and other problems like precipitate, disassociation of EDTA etc. Thus, there is a need to provide all the essential nutrients to plants as a composition and delivery by suitable method so as to achieve ^economical and efficient growth of various parts of the plant.
OBJECTIVES
The primary objective of the present disclosure is to provide a synergistic combination to achieve economical and efficient growth of plants.
Another objective of the present disclosure is to provide an agrochemical composition with synergistic combination of compounds to have remarkable growth and yield of crops, plants and trees.
Yet another objective of the present disclosure is to provide a method for preparing synergistic combination to promote growth of plants.
Still another objective of the present disclosure is to provide a method for promoting plant growth by means of a synergistic combination delivered to plants as an aqueous foliar spray or foliar feeding.

The present disclosure is in relation to an agrochemical composition comprising synergistic combination of essential nutrients, urea, diammonium phosphate and muriate of potash optionally along with acceptable additives.
In an illustrative embodiment of the present disclosure said essential nutrients include macro nutrient(s) selected form a group comprising phosphorous, potassium, nitrogen, sodium, calcium, magnesium and sulphur or combination(s) thereof and micro nutrient(s) selected from a group comprising iron, manganese, zinc, cobalt, copper, molybdenum, nickel, vanadium, boron, selenium, chromium, iodine, fluorine, and cadmium or combination(s) thereof.
In an illustrative embodiment of the present disclosure the concentrations of macro nutrient(s) and micro nutrient(s) is ranging from about 0.001 % to 10 %, preferably about 0.1 % to about 4 %; concenfration of urea is ranging from about 0.2 % to about 0.5 %, preferably about 0.3 % to about 0.4 %; diammonium phosphate is ranging from about 0.02 % to about 0.05 % preferably about 0.03 % to about 0.04 %; and muriate of potash is ranging from about 0.003 % to about 0.005 % preferably about 0.004 % to about 0.0045 %.
In an illustrative embodiment of the present disclosure said composition is in a readily dispersible form.
The present disclosure is in relation to a process for preparing synergistic combination comprising essential nutrients, urea, diammonium phosphate and muriate of potash, said process comprising steps of: adsorbing essential nutrients over the surface of alumina modified silica sol to obtain a powder; and dispersing the powder in water followed by addition of urea, ^diammonium phosphate, muriate of potash to obtain the synergistic combination.
In an illustrative embodiment of the present disclosure said combination is delivered to plants as an aqueous foliar spray.
The present disclosure is in relation to a method for promoting plant growth by means of a synergistic combination comprising essential nutrients, urea, diammonium phosphate and muriate of potash, said method comprising steps of preparing synergistic combination as specified in the above embodiments and followed by delivering to plants as an aqueous foliar spray.
The disclosure is focused to provide a novel combination of essential nutrients in readily absorbable form along with other compounds to form a composition of matter, which composition is significantly more effective in making essential nutrients available to plant tissues and increasing plant growth, regardless of the endogenic synthesizing capability of the plants, than individual compounds of the composition administered separately.
It is vital to note that the concentration of urea is preferably maintained less than 0.5 % so as to prevent leaf bums. The foliar spray has more than 90 % absorption efficiency and the soil application has less than 10 % absorption efficiency. Hence, in the present disclosure the synergistic combination is delivered to plants in the form of foliar spray or foliar feeding to achieve better results.
The technology of the instant Application is further elaborated with the help of following illustrative examples. These illustrative examples are for the purpose of showing the superiority of the present disclosure and are not intended in any way to be self limiting as to the scope of the disclosure. In short, these examples should not be constmed to limit the scope of the invention.
Example: 1 Preparation of essential nutrients powder
It involves adsorbing essential nutrients over the surface of metallate modified silica sol. More particularly, alumina modified silica sol is used for adsorption of essential nutrients. The procedure involved in preparation is described in Indian Patent No. 209364 to obtain the product in powder form. The concentrations of macro nutrient(s) and micro nutrient(s) can be varied at a concentration ranging from about 0.001 % to 10 %, preferably about 0.1 % to about 4 %.
The essential nutrients could be macro nutrient(s) picked up form a group comprising phosphorous, potassium, nitrogen, sodium, calcium, magnesiimi, sulphur and micro nutrients(s) picked up from a group comprising Iron, manganese, zinc, cobalt, copper, molybdenum, nickel, vanadium, boron, selenium, chromium, iodine, fluorine, and cadmium. Also, various combinations of these nutrients are also possible based on the nature of nutrient required by the plant or the nature of deficiency seen in plants.
Example; 2 Preparation of synergistic combination
100 gm of nano nutrient powder, as obtained under example 1, is dispersed in 200 liters of water followed by addition of one kilogram of Urea, 100 gm of Diammonium phosphate [DAP] and 10 gm of Muriate of potash [MOP] to obtain a solution, synergistic combination. The concentration of urea can be varied and is critical in promoting the growth. Hi^er urea concentrations may result in leaf bums. Hence, an optimal concentration ranging from about 0.2 % to about 0.5 %, preferably about 0.3 % to about 0.4 % can be used. As regards DAP, its concentration is ranging from about 0.02 % to about 0.05 % and preferably about 0.03 % to about 0.04 %. MOP concentration can be varied from about 0.003 % to about 0.005 % and the preferable concentration can range from about 0.004 % to about 0.0045 %.
Example; 3 Field study - Napier Grass
As an initial trial study, five plots of land were created by labeling them as below, table 1:
Table 1: Plot numbers and treatment details
Plot 1 Control
Plot 2 Treated with urea only
Plot 3 Treated with diammonium phosphate only
Plot 4 Treated with muriate of potash only
Plot 5 Treated with essential nutrients only
Plot 6 Treated with synergistic combination obtained as per example 2
Plot 2 to plot 6 was treated as per the above table. It was observed that the grass treated with the synergistic combination, plot 6, grew faster and taller when compared vdth the grass in other plots. Additionally, when physically compared for color, it was evident that the plot 6, treated grass, was dark green in color when compared with the other plots which were in lighter green color. The grass of plot 2 was the poorest in color as it involved treatment only using urea. All these results were evident within 30 days time in treated plot 6 whereas the other plots could not achieve the same results within the specified time of 30 days. Thus, from these observations it was evident that the combination used for freating plot 6 is associated with synergistic properties. This was ftirther substantiated with the following experimental studies.
Example: 4 Experimental studies
One gallon each of the following solutions were made up with water and were labeled in the following manner:
> C - Control solution of water
> U - Solution of urea
> D - Solution of Diammoniimi phosphate [DAP]
> M - Solution of Muriate of Potash [MOP]
> EN - Dispersion of essential nutrients
> SYN - Synergistic combination as obtained under example 2
All the solutions are made in comparable concentrations. The solutions were tested in the following manner. Six portions of land for growing potatoes were made and were identified as C, U, D, M, EN and SYN respectively. Each portion of land was treated evenly with respective equal volume of solutions as a foliar spray or foliar feeding. The resuhs of the study are provided below in table 2.
Table 2: Experiment With Potato Crop for 3 Months [ sprayed on 26th, and 75th day]
30 Days
Percentage increase of height, weight of potatoes, dimensions of leaves and other characteristics as evident from portion of land labeled as "SYN" clearly convey that the product is synergistic in nature. The results obtained in "SYN" plot are extraordinary and are on unexpected lines when compared with other plots. None of the results obtained in other plots are no where comparable to the results obtained in plot labeled as "SYN".
Similar studies were conducted using tomatoes, ginger, beans, com, carrots, onions, banana etc. In all the cases the plots which were treated with synergistic combination of example 2 performed synergistically extraordinary. In conclusion, it is evident that final product obtained as per example 2 exhibits synergistic effect on growth, development and nutrient uptake by plants.
