Abstract:
Green gram variety Co-1 was grown with different forms and levels
of phosphates superimposing a treatment of fully burnt lime at 500 kg/ha. The forms of phosphates compared were Mussoorie phosphate, single superphosphate
and a complex fertilizer, factomphos (16:20). The results indicate that
the response of green gram variety Co-1 is limited up to 15kg PgCyha and
that between the forms, there is no significant difference. The use of Mussoorie
phosphate entails a net saving of Rs. 50 per ha at application rates of 15 kg
PjOs/ha. After harvest, if the tops are recycled three-fourths of the N applied
will be returned to the soil. It has been shown that the pulse crop can give a
net profit of Rs, 500 per ha under Kerala conditions.
