Effect of planting dates and plant spacing on growth, yield and chemical constituents of Moringa oleifera plants

A field experiment was carried out in Sohag governorate, Egypt, during two successive seasons, 2017 and 2018, to evaluate the effect of planting dates and plant spacing on growth, yield and some chemical constituents of moringa plants. The planting dates were (May 1st, May 15th and June 1st), and the plant spacing were (10, 20 and 30 cm). The results showed that, generally, planting dates improved growth characters, yield and chemical constituents. The highest values were observed when planting moringa on May 1st. In regard plant spacing, all of them led an increase the growth characters, yield and chemical constituents. The best results when plant spacing was 30 cm between plants, the combined effect between planting dates and plant spacing on moringa parameters was statistically significant. In most cases, planting moringa on the May 1st with plant spacing of 30 cm was the most effective treatment concerning growth, yield as well as chemical constituents.
