Abstract:
The field experiment was conducted at National Seed Project, UAS, GKVK, Bangalore during Rabi-Summer, 2019-2020 to know the influence of designer seed on seed quality, crop performance and seed yield in maize. Experiment was laid out in randomized complete block design (RCBD) with three replications consisting nine treatment combinations. The results revealed that, all the pelleting treatments for designing the seed has enhanced the crop performance and seed yield. Among the treatments, seeds pelleted with Polymer @ 4.0 ml/kg + Metalaxyl @ 3.0 g/kg + (Cyantraniliprole + Thiamethoxam) @ 4.0 ml/kg + Zinc @ 2.0 g/kg + Atrazine @ 10 g/kg+ Azotobacter chroococcum @ 2 g/kg seeds (T₅) recorded less seed mycoflora (2.00%), plant height at 15, 30, 60 DAS and harvest (21.08 cm, 57.02 cm, 132.31 cm and 211.41 cm respectively), number of leaves per plant at 30, 60 DAS and harvest (6.73, 11.53 and 13.73 respectively) and took least days to initiation of 50% tasseling (54.93), least days for.50% silking (58.07), higher cob length (19.86cm), number of cobs per plant (1.53), 100 seed weight.(35.97g), cob dry weight (317.53 g) and seed yield per hectare (107.59 q) with cost-benefit ratio of 1:2.69.
