The Use of Organic Farming to Conserve Biodiversity of Wheat In Palestine

The effect of different fertilizer treatments was studied on the growth and productivity of several wheat varieties . Among these varieties three were of local races (Baladi) and the rest were of the commonly cultivated varieties (Anbar, 870). One level of manufactured organic fertilizer (450kg/dunum) compared with the chemical fertilizer treatment, a combination of both organic and chemical treatment was also included. The experiment was conducted at Biet Qad station. The treatments were randomized in a completely randomized Design (CRD). The experiment revealed the positive effect of organic fertilizer alone and in combination with chemical fertilizer. The production was 1069, and 1070 kg/dunum, respectively. The results also showed significant differences Among the productivity of the different varieties. Regarding tiller numbers, spike number, and spike length differences were also exhibited among the different fertilizer treatments. The fertilizer treatments didn’t affect the plant length, number of seeds per spike and the weight of 1000 seeds. The harvest index was similar for the three local varieties, however, both Anbar and 870 varieties have a higher harvesting index than the other varieties, similar harvest index was obtained in the chemical treatment. The result of this work proved the ability of the local wheat varieties to grow, produce and respond to both organic and chemical fertilizer. The seed content of protien and potassium didn’t differ among the different treatment. On the other hand, the soil analysis revealed a higher nitrate content in the samples obtained from (chemical+ organic) treatment
