Comparative Study of the Effect of Date Palm Compost and Other Organic Amendments on the Soil and Growth of a Barley Crop
摘要
The use of chemical fertilizers and organic amendments is costly for farmers, especially in the arid region. The recovery of date palm waste into compost is an alternative for soil fertility. This study aims to compare the effect of different organic amendments with date palm compost on soil and a barley crop in vegetation pots. The treatments are date palm compost with 3 doses DPC1, DPC2, and DPC3, sheep manure SM, poultry manure PM, industrial compost IC, ground dried palm leaves with poultry manure GP + PM and humic acid HA. The results show that the addition of organic amendments improves soil properties and plant growth in a salty environment. However, the very notable effect is obtained by date palm compost especially for the highest dose DPC3. Its positive effects were marked on the plant: growth, grain yield, weight of 1000 grains and straw yield as well as on the soil especially the increase in organic matter content. It seems that its richness in organic matter has greatly contributed to the physical and chemical improvement of the soil, which has reflected on the good growth of the plant. Finally, date palm compost can create a favorable growth environment for the plant by reducing the aggressiveness of salinity, especially when used in high doses.
