FIELD OF INVENTION:
The present invention relates to the Improved Ortho Silicic Acid (OSA). The present invention in particular relates to the method of preparing Ortho Silicic Acid with improved efficacy.
DESCRIPTION OF THE RELATED ART:
Silicon (Si) has been recognized as an essential trace element for diatoms, Si accumulating plants and higher animals. The best documented function of silicon in vertebrates is its regulatory action in bone calcification and its chemical association with several constituents of the extracellular matrix in connective tissues (Carlisle E. (1989), Silicon, in: Handbook of Nutritionally Essential Mineral Elements, ed. B. L. O'Dell and R. A. Sunde, Marcel Dekker Inc., New York, pp. 603-618). This matrix consists primarily of fibrous proteins such as collagen, embedded in a hydrated polysaccharide gel. Silicon being bound to components of this matrix is regarded to be important for the structural integrity, the development and the regulatory functions of connective tissue. Gastro¬intestinal absorption of Si is only possible after hydrolysis of dietary Si-compounds into ortho silicic acid. The solubility of silicon compounds in the diet is low and consequently these compounds have a limited bioavailability. Organic compounds comprising Si—C bounds are not found in biological systems and several classes of synthetized products were found to have an unacceptable high toxicity. The natural soluble silicon compound, ortho silicic acid also called monomeric silicic acid is present both in fresh and sea water but only at very low concentrations.

OSA has an additive impact when used along with other components to alleviate the chilling stress.
The present invention describes the role of ortho silicic acid (OSA)formulations in alleviation of plant stresses viz. water, salinity, sun bum in fruits and chilling stress. Analysis were conducted to substantiate the impacts of described formulation in mitigating damages to crop under stressed conditions by monitoring the physiological and biochemical parameters
Example 6: Impact of OSA formulations in alleviation of water stress conditions by assessing physiological and biochemical parameters. Analysis done in vitro by simulating the stress conditions using poly ethylene glycol (PEG 6000). Two concentrations of PEG 6000 were used i.e. 10% (w/v; -0.4 MPa) iand 20% (w/v; -0.8 MPa). Experiments were conducted using maize as experimental systems. The seedlings were initially raised in the normal Hogland's solutiqn and 2-week-old seedlings were transferred to medium with PEG 6000. The impact of PEG 6000 were compared with the medium having combination of formulation described above without OSA (For w/o OSA) and with OSA (For. with OSA). Observations were recorded for various growth , physiological and biochemical parameters were recorded after 1 month of incubation. During the course of the study, medium was replaced periodically. Table 1: Impact of formulations in ameliorating the impact of osmotic stress
induced by PEG 6000.

Impact of osmotic stress reduced considerably in presence of the. formulations (Table 1). The impact of addition of OSA in the formulation has improved the crop vigorunder stressed conditions. Physiological parameters like relative water content (%) and membrane leakage was recorded for seedlings raised under

various combinations (Figure 1). Addition of formulation has significantly reduce the impact of osmotic stress for both the physiological parameters, however, addition of OSA in the formulation was recorded to have a better impact. Figure I shows amelioration of impact of PEG 6000 induced osmotic stress on maize seedlings on physiological parameters.
Field analysis was conducted where maize was allowed to grow till knee height stage under optimum levels of water. After attaining the required growth, foliar sprays of formulation was one @ 4ml/l of water. Equal volumb of water was sprayed in all treatments. Control was water sprayed. Stress was imposed by withdrawing the irrigation for three weeks. Different physiological and biochemical parameters were analyzed after three weeks. Leaves iwere harvested and analyzed by accumulation of various biochemical parameters to assess the impact of foliar spray of formulations (Table 2).

Thus the foliar spray of formulation is alleviating the impact due to; stress. Higher levels of proline are accumulated under stress condition to protect the cells due to generated ROS and also act as osmoregulant. Increased soluble sugars enables cells to maintain turgidity and its conversion to starch is reduced! considerably, which ultimately leads to reduced growth due to reduced levels of starch.
Example 7: Salinity stress was induced by addition of different levels of NaCl
and studies were conducted under in vitro conditions.
Seed germination analysis were conducted on wheat using Petri plates. Salt stress
was induced by adding two levels of NaCl (60 mM and 120 mM). Seeds were
germinated in water. Observations were recorded after 10-days of] germination.
Experiments were repeated maintaining same number of replicates all time. Ionic
content was measured in 10-day-old seedling using Flame Photometer.

i plants were irrigated with the water having aforesaid levels of NaQl. Foliar sprays

Sun burning of fruits is emerging as serious problem for horticultural crops owing
to climate change. This often reduces the quality of crop thus results in lower
market price. !
Foliar sprays were started on berried once they attained the size of 8-10 mm and
the atmospheric temperature started to rise gradually. Three applications were
taken at an interval of 10 and 15 days to assess the impact on reducing incidence

recorded in berries when three applications were taken at 10 days interval,
compared to two sprays at 15 day interval (Table 6). Formulation with OSA
performed better than the one without OSA. i
