Importance Of Silicon fertilizer In Agriculture

 

Benefits of silicon | beneficial effects of silicon (si) in agricultural crops :-

WATCH NOW

Leaf erectness :-

Silicon give cell wall rigidity and Max Live erect due to this sunlight reaches all areas to the plant that make them to do more photosynthesis properly that's make more growth and higher yield. 

Counteracts negative effect of high nitrogen supply :-

Silicon contracts negative effect of high nitrogen supply, due to high nitrogen application there is high vegetative growth of plants and plant becomes very heavy then plant lodging occurs ( mainly in rice) and also disease and pest attack becomes high when nitrogen fertilizer ( mainly urea) are high, so silicon stops the uptake of nitrogen when there is no need in plant.

Resistance to disease and pest:- 

1.Produse more Lignin so that fungal infections are less. 

2. Make a very thin Silicon layer into the leaf epidermal cell so that leaves become harder and pest can't sucks the SAP through injecting their mouthparts( needle like structure). 

Controls abiotic stress:- 

1. Silicon alliviate the abiotic stresses such as lodging, drought, UV radiations, high and low temperature, freezing, and rainfall. 

2. Minimise the effect of strong wind( from lodging)  because the leaves and stems of plants are become harder due to Silicon application. 

3. Filters the UV rays coming from sun light( mainly in sunlight and paddy ) by biosynthesis of phenolic compound. 

Enhance  availability of internal phosphorus:- 

when the movement of phosphorus in soil occurs then excess of iron(fe) and manganese(mn) stops the Phosphorus movement so this Silicon Stops the excessive uptake of iron and magnese and this enhances Phosphorus availability. 

Alleviate the Magnus toxicity:- 

Silicon oxidized Magnese, and hence this oxidised Magnese will can't taken by plants. 

Also alleviate heavy metals toxicity such as zinc, aluminum, cadmium etc.

Reduces salt stress:- 

(especially in rice) silicone blocks the transpiration path through which salt is taken (example sodium) . 

Silicon also deposited in roots and inhibits the salt entry. 

Several beneficial effect in rice and sugarcane:-

Rice:-

1.Silicon reduces brown crop hopper pest in rice.

2.reduces lodging in rice

Sugarcane:- 

Silicone increases sweetness in sugarcane:- Silicon reduces activity of invertase enzyme in sugarcane due to this sucrose content increases does sweetness increases in sugarcane.
