Effect of sowing dates on qualitative traits in Vegetable Pea (Pisum sativumL.)

The effect of sowing dates on the qualitative traits of Vegetable pea (Pisum sativum
L.) was investigated to determine how planting time influences the qualitative traits of
vegetable pea. Twenty genotypes of Vegetable pea were used in the experiments which were
collected from NBPGR New Delhi, IARI New Delhi and different districts of Bihar
(Begusarai, Samastipur, Bhagalpur etc.). In this study, vegetable peas were sown at different
dates i.e., 15th October, Last week of October, and 1st week of November and various
qualitative traits, including TSS Content, Total Sugar, Reducing Sugar, Protein Content and
ascorbic acid were assessed. These all qualitative traits were observed minimum for IC-
342046 and maximum for 5438/P-2110 which was at par with all four checks (Pusa Prabhat,
Arkel, GS-10, and Punjab 89). When comparing early-planted vegetable pea on October 15 th
to other sowing dates, noticeably larger TSS Content, Total Sugar, Reducing Sugar, Protein
Content and ascorbic acid was found which indicates that the sowing date determined the
level of qualitative traits in vegetable pea. The current study found that early sowing dates
generally produced better qualitative characteristics in vegetable pea. Predicting the ideal
time to plant might be challenging due to unseasonable rains, temperature fluctuations, or
frost events. The development of crop management techniques that can adjust to climatic
variability and harsh weather events is aided by research on sowing dates. Farmers can better
adapt to variations in temperature and precipitation patterns by modifying the time of sowing.
