| Abstract | ||
| Field and storage experiments were conducted during 2014 and 2015 seasons. The field experiment was carried out at the experimental station of the Faculty of Agriculture, Cairo university ,Giza, Governorate Seeds of field corn , 352 and 323 triple hybrids were sown 1st May,1st June and 1st July and harvested 1, 2 and 3 days after silk emergence. Ears from the previous experiment (three planting dates and three harvesting dates) were stored at 5 °C and 90 – 95 % relative humidity for 15 days to investigate the effect of hybrid, planting date and harvesting date on accumulated heat units growing degree days (GDD), vegetative growth, ear characters, yield and storability of baby corn ears. Results showed that baby corn plants needs 1747.6, 1694.2 (GDD) for 323 hybrid and 1822.8 and 1745.4 for 353 hybrid to reach the optimum harvest stage of ears with the best quality ( 2 days after siliking) for the first and second seasons, respectively. Results revealed that 353 hybrid had significantly increment in vegetative growth parameters and produced higher total yield and its components per Fadden than those obtained by 323 hybrid. 353 hybrid planted on 1 st May and 1 st June had the highest vegetative growth and total yield and its components (ear weight and number of cobs / m 2 while 323 hybrid planted in 1 st June was the lowest ones in these characters.The best value of ear length and ear diameter concerning to marketability were obtained from 353 hybrid which planted in 1 st May and harvested after 2 days from silk emergence being about 9.32 cm and 10.38 mm, respectively. For storability, General Appearance (GA) in ears obtained from planting on 1 st May and harvested after 2 days from silk emergence did not exhibit any changes in their appearance till the end of storage period (15 days).,also gave the lowest weight loss % , had highest L value ( indicating lighter color) and b value ( indicating light yellowing) and maintained total sugars during storage. | ||
