Abstract:
A field investigation on “Effect of different levels of nitrogen and potassium on economics of sweet corn (
Zea mays (L). var.
Saccharata)” was carried out at Instructional Farm, Department of Vegetable Science, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during summer season of year 2018-19. The experiment was laid out in Factorial Randomized Block Design having fifteen (15) treatment combinations and three (3) replications. Among the two factors studied, the factor A
i.e. nitrogen (N) was applied in five different levels
i.e. N
1 (150 kg ha
-1), N
2 (175 kg ha
-1), N
3 (200 kg ha
-1), N
4 (225 kg ha
-1) and N
5 (250 kg ha
-1). While, another factor B
i.e. potassium (K) was applied in 3 different levels such as K
1 (60 kg ha
-1), K
2 (80 kg ha
-1), K
3 (100 kg ha
-1). Cob yield with husk per hectare was observed maximum at level N
5 (250 kg ha
-1), level K
3 (100 kg ha
-1) and treatment combination N
4K
2 (225 kg N + 80 kg K
2O ha
-1).
Green fodder yield per hectare was observed maximum at level N
5 (250 kg ha
-1), level K
3 (100 kg ha
-1) and treatment combination N
5K
3 (250 kg N + 100 kg K
2O ha
-1). Highest net return and highest benefit cost ratio were observed at treatment combination N
4K
2 (225 kg N + 80 kg K
2O ha
-1).
