Abstract
The field investigations were conducted to study the effect of date of sowing, spacing and sowing method on yield, quality and incidence of diseases on single harvest garden pea for two years (2016-17, 2017-18) at Vegetable Research Farm, Department of Vegetable Science, Punjab Agricultural University Ludhiana, India. The experiment was laid out in split plot design with 30 treatments comprising five dates of sowing, viz. 20th October, 5th November, 20th November, 5th December and 20th December in main plots and 2 different planting methods (flat and bed) sown at three different spacing (20 × 5 cm, 20 × 7.5 cm and 20 × 10 cm) in subplots and replicated three times. It is concluded that sowing of garden pea cv. Punjab-89 on 5th November at intermediate spacing of 20 × 7.5 cm using bed sowing method resulted into significantly higher green pod yield (12.75 kg/9m2) in single harvest. The non-significant interactions were observed between date of sowing and spacing for pod length, pod weight, plant height, shelling percentage, dry matter content, alcohol insoluble solids and reducing sugar. It was observed that late sown (20th December) crop took minimum days to 50% flowering and had least incidence of rust disease but resulted into lower green pod yield (4.50 kg/9m2) due to availability of shorter duration from flowering to harvest. However, powdery mildew disease symptoms do not appear in field during both the years (2016-17 and 2017-18) but the rust incidence was maximum (44.42%) on 20th November sown crop which was significantly higher than 5th November and 20th October sown crop.
