WITHDRAWN: Standardizing agronomic practices for mechanical harvesting of the single-harvest garden pea (Pisum sativum L.) in India

Abstract

The field investigations were conducted to study the effect of time of sowing, spacing and sowing method on yield and its attributing traits on single-harvest garden pea to standardize the agronomic practices for mechanized cultivation in India. The experiment was laid out in split-plot design with 30 treatments comprising five dates of sowing in main plots and 2 different planting methods (flat and bed) sown at three different spacing in subplots and replicated three times. The bed size was standardized according to front-loading width of the pea combine. Significant interactions were observed between the date of sowing and spacing for a number of pods per plant, green seeds per pod, green pod yield per plant, green pod yield per plot; date of sowing and sowing method for pod length; spacing and sowing method for plant height. However, for all the traits, there was non-significant 3-way interaction. The late sown (20th December) crop resulted in the lowest number of pods per plant, green seeds per pod, green pod yield per plant and green pod yield per plot which was due to high temperature and low relative humidity at pod development and filling stage. It is concluded that the sowing of garden pea cultivar Punjab-89 on 5th November at an intermediate spacing of 20 × 7.5 cm using bed sowing method resulted in significantly highest green pod yield of 12.75 kg/9m2 in the single harvest.
