Abstract

Maymunah Horticulture Station, Agriculture Directorate of Maysan. The experiment included 24 treatments of possible combinations between three sowing dates (T1=15/12, T2=31/12 and T3=15/1), two soil mulching treatments (M2=mulching the soil by black polyethylene, M1=Without mulching) and four concentrations of calcium fertilizer (Ca) (0, 0.5, 1 and 1.5 ml.l-1), to study its effect on the quantitative yield characteristics of Okra plant cultivar "btayrh". The results showed that cultivated plants at date (15/1) showed significant increase in number of pods per plant, weight of pod, length and diameter of pod, the yield per plant and early yield compared to plants of dates (15/12 and 31/12). The cultivated plants in mulching soil were significantly higher in all studied quantitative yield characteristics. The sprayed plants with calcium (1ml.l-1) were superior in all studied quantitative yield characteristics. The interactions between the studied factors were significant in all the quantitative yield characteristics. The cultivated plants at date (15/1) with mulching and the sprayed by calcium fertilizer (1 ml.l-1) gave the highest values of length & weight of pod, the yield per plant and early yield per plastic house (6.31cm, 4.08g, 81.32g and 0.180 Kg.m-2) respectively. While the cultivated plants at (15/12) and un mulching soil and unfertilized gave the lowest values (2.49cm, 3.58g, 38.50g and 0.085 Kg.m-2) respectively. In conclusion the present study indicated that growth and yield of okra cultivar increased by the addition of 1ml.l-1 calcium which planting on 15 January and mulching soil.
