Effect of Irrigating Pearl Millet with Treated Grey Water

This study was implemented in order to examine the effect of reused treated grey water on yield of 10 Pearl millet accessions (Pennisetum glaucum [L ] Leeke). The experiment was conducted in the research station of Faculty of Agriculture, An – Najah University,Tulkarm,Palestine. The seeds were planted in the summer season 2010, in separated plastic containers filled with 45 kg sandy clay soil, ten plants were planted in each container, the distribution of the plots was completely randomized plot design. The plants were irrigated with three types of water (Fresh water as control, raw grey water, treated grey water), with four replicates for each treatment. The collected data were analyzed statistically using two way analysis of variance to examine treatment effects, means were separated by Duncan's multiple range test at P≤0.05. The results show clearly that there are no significant differences of the yield under different water treatments. No significant interaction was observed between water treatments and accessions. At the same time, accessions 1,5,6, and 7 gave high total fresh weight (1152.5 g/plant , accession 1), however , accessions 6,7,8,10 gave significantly the highest root fresh weight (244.67 g/plant , accession 7), for the straw fresh weight , accessions 1 and 5 have the highest straw fresh weight (940.5 g/plant accessions 5). Regarding the plant length, accessions 2,3,4 and 10 gave the highest plant length(70 cm line 2). These results are showing a totally different pattern of production among the accessions, where accessions 1 and 5 significantly have the highest total dry weight, while for the fresh weight in addition accessions 1,5,6 and 7 significantly have the highest fresh weight . The results of seed production indicate that accessions 6,7,8, 9, and 10 gave significantly the highest seed dry weight. It is concluded that lines 1and 5 are the highest productive lines regarding both fresh and dry weight, while accessions 6,7,8,9,10 have the highest seed production
