Abstract
The present investigation was undertaken to optimize the sowing time of edible pod
pea genotypes. The experiment comprising of 12 treatments i.e. three sowing dates
(21st October, 5th November and 20th November) and four genotypes namely, DPEPP-
15-1, DPEPP-10-1, Arka Apoorva and Meethi Phali was conducted in split plot
design in three replications at the Experimental Farm of Department of Vegetable
Science and Floriculture, CSKHPKV, Palampur for two consecutive years during
winter 2018-19 and 2019-20. Both the factors i.e. sowing dates and varieties
significantly influenced the yield and majority of its attributing traits. Early sown crop
on 21st October resulted in early flowering and first picking along with higher pod
yield, pods/plant, nodes/plant, pod length, harvest duration, total soluble solids (seeds
and whole pod), ascorbic acid, seed yield, straw yield, biological yield and monetary
gains which was followed by 5th November sown crop. Among the varieties, DPEPP-
15-1 was the most promising genotype followed by DPEPP-10-1 for yield and yield
contributing parameters viz., pods/plant, pod yield, harvest duration, seeds/pod,
average pod weight, seed yield, straw yield, biological yield, harvest index and 100
seed weight besides provided high gross return, net return and B:C ratio. DPEPP-10-1
showed significantly superior performance for early harvest, more nodes/plant, pod
length, small internodal length, high total soluble solids (seeds and whole pod) and
ascorbic acid. Both these genotypes significantly outperformed the recommended
varieties Arka Apoorva and Meethi Phali. Genotypes DPEPP-15-1 and DPEPP-10-1
had advantage of 36 and 27% for fresh yield and that of 53 and 45% for seed yield
(q/ha) over variety Arka Apoorva on pooled basis, respectively. Interaction effects
between sowing dates and varieties revealed that sowing of DPEPP-15-1 on 21st
October followed by 5th November had significantly higher pod and seed yield,
pods/plant, harvest duration, straw yield and biological yield besides provided
maximum monetary gains whereas DPEPP-10-1 got second rank but they
significantly outperformed the check varieties Arka Apoorva and Meethi Phali. They
also provided maximum monetary gains under early sown conditions with net return
of Rs.2.48 lakhs/ha and 2.35 lakhs/ha, respectively.
