Influence of Spacing and Varieties on Growth and Yield of Baby Corn (Zea mays L.)

Abstract

A field experiment was conducted during kharif, 2021 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U. P). The soil of given experimental plot was sandy loam in texture, neutral in soil reaction (pH 7.1), low in organic carbon (0.36 %), available N (171.48 kg/ha), available P (15.2 kg/ha) and available K (232.5 kg/ha).The experiment was laid in Randomized Block Design with Ten treatments and three replications. The treatments are as follows, T1: G-5414 + 40 cm x 15 cm, T2­: G-5414 + 50 cm x 15 cm, T3: G-5414 + 60 cm x 15 cm, T4: G-5417 + 40 cm x 15 cm, T5: G-5417 + 50 cm x 15 cm, T6: G-5417 + 60 cm x 15 cm, T7: Shine-60 + 40 cm x 15 cm, T8: Shine-60 + 50 cm x 15 cm, T9: Shine-60 + 60 cm x 15 cm are used. The results showed that application of treatment Shine-60 + 60 x 15 cm was recorded highest plant height (172.38 cm), No. of leaves/Plant (12.75), Plant dry weight (90.00 g/plant) whereas, Crop Growth Rate (39.77 g/m2/day) and Relative Growth Rate (0.036 g/g/day) was recorded significantly highest in treatment G-5414 + 40 cm x 15 cm. However, No. of Cobs/Plant (2.82), length of the Cob/Plant (17.55 cm), Cob weight with husk (44.18 g), Cob weight without husk (17.94 g), Cob yield with husk (28.78 t/ha) and Cob yield without husk (6.87 t/ha) was obtained in the treatment of Shine-60 + 60 cm x 15 cm as compared to the other treatments.
