Abstract
Field experiment was conducted at the experimental farm of the Central Laboratory for Agricultural Climate, Agricultural Research Center, Giza, Egypt, during two successive seasons of 2017 and 2018. This experiment aims to improve the organic production of sweet corn via some organic extracts under different sowing dates. The seeds of sweet corn (Misthi F1 Hybrid) were planted on three different dates on 15 April, 10 May and 5 June in both seasons. Extracts of compost, vermicompost and chicken manure with applying half dose of compost were compared to full dose of compost. Results showed that early sowing had positive effect on growth, yield and ear properties of sweet corn. Applying half dose of compost with adding vermicompost extract gave the highest growth, yield and ear properties of sweet corn without significant differences compared to 50 % compost + chicken manure extract treatment in plant height and leaves number per plant. The treatments of the half dose of compost with adding any organic extracts were superior to the full dose of compost in all studied traits. This study revealed that early planting (April 15) with applying a half dose of compost + vermicompost extract produced the highest yield and quality of sweet corn ears.
