Abstract


A field experiment was conducted from February to April 2015 at College of Horticulture, Vellanikkara to identify suitable varieties and optimum plant spacing of baby corn (Zea mays L.) in summer rice fallows of Kerala, to be used as vegetable and fodder. The treatments included planting of three baby corn varieties viz., G 5414, CO 6 and NSC 1009 B under four different plant densities viz., 60 cm x 15 cm, 50 cm x 15 cm, 40 cm x 15 cm and 30 cm x 15 cm. Green cob and baby corn yield were similar among the  varieties, whereas green fodder yield was highest for CO 6 (32 Mg ha-1). Among different spacing levels, 30 x 15 cm spacing gave higher green cob (12.48 Mg ha-1), baby corn (3.22 Mg ha-1) and green fodder yield (34 Mg ha-1). The variety NSC 1009 B was superior in terms of least number of days for tasseling and silking . The variety G 5414 produced highest number of three cobs per plant. The variety CO 6 at 30 x 15 cm resulted in the highest B:C ratio.
