ProGibb - improves water deficit tolerance in maize plants

What is ProGibb?

Active Ingredient is:

• Gibberellic Acid (GA3)

• Naturally occurring plant hormone

• Promotes cell division and cell elongation

• Improves early season plant vigor and helps plants recover from stressful conditions caused by adverse weather.

• More crop vigor for increased Yield potential

• Increased no of grains per cob

• Increase in grain weight and overall grain Yield

Gibberellins:

• Produced by natural fermentation

• Fermentation utilizes natural strains of G. fujikuroi selected for high GA3 production yield 

• Highly sophisticated fermentation and recovery processes deliver a highly purified technical

grade material

• In the USA, gibberellins are classified as biologicals, and are exempt of the requirement of residue tolerance for all crops, rates and applications

ProGibb Demonstrations:

Plot selection:

1. Select plot with proper germination

2. Having good irrigation facility

3. Soil should be fertile.

4. Plot should be properly leveled

Method:

Time of application :

Crop satge : 4-7 leaf stage (20-25DAS)

Dosages : 7g/acre

Process:

1. Dissolve promix in 1 lt water

2. Add ProGibb to promix solution and stir well to have uniform solution

3. Add water to ProGibb solution to Make final volume 8Lt.

4. Fill half tank of Knapsack sprayer with water and add 1Lt ProGibb solution. Fill the tank with water and spray in the field. Total 8 tanks required per acre for thorough spraying.

Field visit:

Time : Visit plots at cob maturity and look for following parameters:

1. Cob length : Measure cob length for 20 cobs from ProGibb treated and non-treated plots

2. Column in each cob: Count no. of column from 25 cobs from each plot

3. No. of grains: Count no. of grains from 10 cobs from treated as well as untreated plots.

4. Weight of grains: Weigh grains from 10 cobs from each plot.

Important things to consider

1. Field should not have any kind of fertilizer/moisture stress

2. Proper dose and water volume

3. Don’t mix any foliar fertilizer, copper or sulphur fungicide along with ProGibb application.

4. Spraying should be done during morning or evening hours.

Remember Early application always pay more ProGibb in Maize Crop

• Spray ProGibb on 20-25 days crop that’s when there is 5-8 leaf stage.

• Dose - 1 gm per spray pump and farmer is using 6-7 pumps per acre.

• Farmer is asking for broadcasting method, but it is observed that Maize is growing mostly as rain- fed crop, so ProGibb application with broadcasting is possible only when there is optimum moisture in the soil.(Will test ProGibb as broadcast method 10 gm per acre in irrigated area in next season)

• Used flat- fan or holo-cone type nozzle in application.

• Field free from weeds and water stress condition.

Instructions:

• ProGibb should be mixed in ProMix solution first .

• At spraying time, optimum moisture content in the soil gives better result.

• Check the field conditions thoroughly before claiming about ProGibb result like

a) In low land area where water drainage is not good ProGibb is not giving good results.

b) In field where there is stalk -rot problem or same hybrid is growing from so many years ProGibb result can be affected.

c) In fields where there is shadow of trees , the ProGibb result is less visible.

• During ProGibb spray the insect attack should be checked i.e. during this stage farmer is using products for early shoot fly ,borer ,termite and beetle so DanTotsu and DaniTol can be promoted for better control.

• In field shows , its better if farmer starts telling about difference between ProGibb and untreated ,sometimes he explains better!!!

Hence, ProGibb gives yield equal to 11 Acres from 10 Acres of land. i.e. ProGibb can increase 10% of farmer holding of -course by 10 % minimum extra yield.
