Thank you for completing this exercise.

Now you may review this Module or select next Module i.e. Module VI from Course contents.



Module V


You are right.

Low pearl millet yield in India is mostly due to the crop being traditionally cultivated under unfavorable conditions.

Module V


Your answer is not correct.

Pearl millet is a non-legume.

The correct answer is:


Continue



Module V


Your answer is partly correct, but:



Continue



Module V


You are right.

Application of manures and fertilizers is important in pearl millet to take advantage of the high yield potential of improved varieties and hybrids of pearl millet.

Module V


You are right.

The recommended rate of nitrogen for irrigated pearl millet is 100 to 120 kg N/ha.

Continue



Module V



30 to 60 kg N/ha is recommended for pearl millet under good rainfall conditions.


The recommended rate of nitrogen for irrigated pearl millet is 100 to 120 kg N/ha.

Continue



Module V


Your are right.

Ammonium sulfate in addition to nitrogen also contains sulfur (16%), which will be needed to pearl millet in soils deficient in sulfur.

Continue



Module V



Ammonium sulfate is neither cheaper or higher in nitrogen than urea.


Ammonium sulfate in addition to nitrogen also contains sulfur (16%), which will be needed to pearl millet in soils deficient in sulfur.

Module V


You are right.

The need to apply potassium to pearl millet depends on its availability in the soil. So, soil testing information is required for taking the decision.

If the soil test reveals that the available potassium is less than 150 kg of K2O/ha, then there is a need to apply potassium in that field.
