Grain Filling, Test Weight and Returns

Understand the connection between grain filling, grain quality, test weight and returns.

Grain Filling, Test Weight and Returns

TopGrain® is India's first dedicated Grain Filling Technology, designed specifically for paddy and wheat. It works at the physiological level to strengthen the crop's natural grain-filling process and help transfer the plant's growth potential into developing grains.

It supports efficient sugar movement and starch formation during grain development, helping the crop convert growth into yield.

Better Grain Filling • Improved Grain Weight • Higher Yield Potential

Grain Weight

Grain filling contributes to final grain weight. TopGrain® is positioned to increase grain weight and size through better filling.

Grain Uniformity

Uniform filling across the panicle or ear head supports more consistent grain development and uniform grain size.

Test Weight and Quality

The stated benefits include bolder, heavier and well-filled grains and improvement in key quality parameters such as test weight.

Marketable Yield and ROI

Better grain filling is positioned to convert existing crop potential into harvestable yield, with increased quality supporting profitability and value for money.
