 ABSTRACT

The field experiment was laid out in the experimental field of department of Horticulture, College of Agriculture, Rajmata Vijayaraje   Scindia Krishi Vishwa Vidyalaya, Gwalior (M. P.) during autumn-winter season. Experiment was conducted in factorial randomized blocked design with three replication comprised of eight treatments combination (K1VC0, K1VC1, K2VC0, K2VC1, K3VC0, K3VC1, K4VC0, K4VC1). On the basis of both the year, the data reveals that the treatment K3 (150 kg K2O) was observed significantly  maximum in all physiological parameters followed by K2 (100 kgK2O/ha) as compared to other treatments .However, it was recorded minimum in treatment K1 (50 kgK2O/ha).In case of vermicompost, the treatment VC1 (20 t VC ha-1),recorded significantly maximum in all the parameters while minimum was observed in VC0 (0 t VC ha-1).Significantly maximum in all parameters (Leaf area plant ,leaf area index, NAR and CGR) were noted in treatment combination K3VC1 (150 kgK2O/ha + 20 t VC/ha) followed by K2VC1 (100 kgK2O/ha+ 20 t VC/ha) at 30, 60 and 90 DAP, respectively. While, it was recorded lowest in treatment K1VC0 (50 kgK2O/ha + 0 t VC/ha). The interaction effect of year and potassium (YXP), year and vermicompost (YXV) and year, potassium and vermicompost (YXPXV) on leaf area plant-1 were non-significant in all parameters (Leaf area plant-1, leaf area index, NAR and CGR) at 30,60, and 90 DAP respectively.

Key words: NAR, CGR, LAI, Vermicompost, Potassium
