Abstract:
There was an investigation regarding, Effect of seed soaking treatments on growth, yield and quality of baby corn (Zea mays L.) at farm of the Horticulture Polytechnic, ACH, Navsari Agricultural University, Navsari, Gujarat, India during the summer of 2023 on var. GAYMH-1. The experiment had a randomized block design (RBD) and included seven different treatments, including, T1: 6-Benzyl adenine (Cytokinin) 50 ppm; T2: GA3100 ppm; T3: PBZ 50 ppm; T4: Mepiquat Chloride 100 ppm; T5: CCC 100 ppm; T6: NAA 50 ppm and T7: control (Water soaked).
On the one day before sowing, seeds were soaked with all the treatments for 24 hours and kept in the shade for 3 hours. Among treatments, seeds soaked in GA3 100 ppm (T2) reached 50% germination one day earlier than the control with the highest germination percentage (93.03%). The highest plant height (77.17 cm, 211.20 cm, and 220.13 cm at 30, 60DAS, and at last picking, respectively), was recorded with NAA 50 ppm (T6) and it attained 50% silking in 57.67 days which was 0.33 days earlier than control. Effect of seed soaking treatments of NAA 50 ppm (T6) was detected in getting a higher number of cobs plant-1 (2.40), length of cob (13.50 cm), cob girth (4.84 cm), the diameter of cob (14.51 mm), average weight of cob (84.980 g with husk and 20.213 g without husk), yield of cob plant-1 (150.545 g with husk and 41.567 g without husk), cob yield ha-1 (12.144 t with husk and 2.716 t without husk) and green fodder yield (36.111 t ha-1). The fresh weight basis were used to analyze the qualitative parameters of the cobs and obtained the highest protein (26.71 mg g-1) and reducing sugar (1.82%) content with GA3 100 ppm (T2). However, higher total sugar (3.93%) and (2.04%) content was obtained with NAA 50 ppm (T6).
