Abstract:
An investigation was carried out at the College of Horticulture, Dapoli, Ratnagiri (Dist.), during the period Rabi season to study the effect of consecutive sowings and spacing on growth and yield of amaranthus. The study was conducted with three consecutive sowings of radish viz. C₁- Sowing during second fortnight of October., C₂-Sowing during second fortnight of November and C₃- Sowing during second fortnight of December viz., T₁-20 cm spacing between two rows., T₂-30 cm spacing between two rows., T₃-40 cm spacing between two rows and T₄-Broadcasting. The C₁ i.e. (Sowing during second fortnight of October)_, C₂ i.e (Sowing during second fortnight of November) observed better performance in number of leaves and average leaf area However, C₃ i.e., sowing during second fortnight of December was performed better and found significantly superior over other sowing time in respect of weight of per plant and yield per plot. However, days to germination, plant height, dry matter of leaves and ascorbic acid content was found significantly superior in C₁ i.e., sowing during second fortnight of October. In respect of spacing, the spacing T₁ i.e., 20 cm row spacing was found significantly superior in plant height and average leaf area while, the spacing T₃ i.e., 40 cm row spacing significantly superior in dry matter of leaves, however the spacing T₄ i.e, broadcasting significantly superior in yield per plot. In respect of interaction of consecutive sowings and spacing, the treatment combination C₁T₃ was found significantly superior in plant height while, average leaf area was and highest yield per plot was found in C₃T₁ and the maximum dry matter of leaves was found in C₁T₄. Hence, the treatment C₁T₃ (October sowing with 40 cm row spacing) was found to be most profitable.
