seed yield and yield attributes of onions as influenced by surface cutting, weight, and planting date of mother bulbs

Purpose: this investigation aimed to study the effect of mother bulbsurface cutting, weight and date of planting on plant growth, seedyield and seed quality of onions. research method: the experimentwas conducted during 2020 at the agriculture research farm ofkabul university. the study was designed in split-split plotrandomized complete block design (rcbd) and data for plantbiometry, seed yield and seed quality was recorded. the recordeddata were statistically analyzed with r software. findings: the studyrevealed that, surface cutting of mother bulbs alone does notinfluence plant growth and seed yield. however, the interaction oflarge bulb and bulb surface cutting was significant on seed yield. thelarge sized whole bulbs produced higher seed yield (938.33 kg ha^-1)as compared to other treatments. early planting produced vigorousplants as compare late planting. large bulbs (126-175 g) producedvigorous plants and highest seed yield (820.83 kg ha^-1). however,the seed yield (805.83 kg ha^-1) produced by plants obtained frommedium bulbs (76-125 g) was on par with those produced fromlarge bulbs. research limitations: no limitations to report.originality/value: based on the findings of the study, the farmersare recommended to avoid the surface cutting of mother bulbs andfollow early planting (20th march) of medium sized bulbs (76-125 g)for vigorous plants and higher seed yield of onion.
