सवाल

Which syllabus does this course follow?

The course follows the ICAR 5th Deans' Committee B.Sc (Hons.) Agriculture syllabus used by UP agricultural universities (CSAUAT Kanpur, ANDUAT Ayodhya, SVPUAT Meerut, BUAT Banda) and agriculture colleges of UP state universities. Where your own university syllabus differs, the centre follows your university syllabus.

Will fertiliser calculations be practised?

Yes. Urea, DAP, SSP and MOP quantity calculations for a given NPK recommendation are practised many times.

Are deficiency symptoms taught with examples?

Yes. Symptoms are explained crop-wise with photos from field visits and the textbook.

Do you give tests?

Yes. Unit tests and a full syllabus test are given.
