Abstract

Sweet corn (Zea mays convar. sacharata var. rugosa) also called sweet corn, sugar corn, pole corn is a variety of maize with high sugar content (protein 3.2g, sugar 3.22g). Sweet corn is the result of a naturally occurring recessive mutation in the genes which control conversion of sugar to starch inside the endosperm of the corn kernel. Since sweet corn needs to be consumed in a short time after harvest, it fits well in peri urban agriculture. The major problems during growth period are incomplete kernel development, ears partially filled with ripe kernels, shrivelled kernels. An attempt is made to overcome this problem by spraying of liquid organic manures with regular intervals. This study comprised of eight treatments with four replications, adopting RBD. It revealed that the combined application of FYM @ 10t/ha with two sprays of panchakavya 3% at fortight interval by recording the highest values in all growth and yield parameters by maintaining the soil fertility and productivity.
