Abstract:
The experiment entitled “Effect of pinching and mulching on growth and yield parameters in china aster (Callistephus chinensis L.) cv. Phule Ganesh White” was conducted during Rabi-Summer season of the year 2022-23 at College of Horticulture, DBSKKV, Dapoli, Dist. Ratnagiri, Maharashtra. The experiment was laid out in Split Plot Design with three replications and two factors i.e. Pinching and mulching. Pinching constituted four treatments viz. P₁ –Pinching after 3 weeks of transplanting, P₂ – Pinching after 5 weeks of transplanting, P₃ – Pinching after 3 and 5 weeks of transplanting, P₄ – No pinching. Mulching as sub factor constituted four treatments viz. M₁- Black polythene mulch, M₂- Silver polythene mulch, M₃- Paddy straw, M₄-No mulching. Thus, two factors with three replication and total sixteen treatment combinations were tested during this investigation. In case of mulching black polythene mulch found best with respect to minimum weed intensity. In respect of pinching methods, maximum yield was recorded with double pinching.
