Hi,

Ft2 and square meter are the same (units)？Could you explain what are kernel weight and 1000 grain weight mean? For the time being I do not have so much comment or questions.

Thanks

One square meter is 10.8 square foot. Kernel weight refers to the weight of each individual rice grain, and 1000 grain weight is the weight of 1000 grains, usually in grams. This can vary with grain type and size.

I am responding to the question: Need your help in solving this. Given: Density/m2 = 260 Avg No. of filled grains per panicle = 136 Test weight of rice = 20 g Rice yield t/ha = ?

I am assuming that the 20g test weight is the that 1000 grains weighs 20g. If that is the case the yield is 7070 kg/ha. The 260 panicles/m2 is low. In CA rice systems we would like to see about 700 panicles/m2 to maximize yields. The low number of panicles is somewhat compensated by having large panicles.
