<strong>Some essential oils isolated from Egyptian plants viz, </strong><strong><em>Mentha microphylla</em></strong><strong> C. Koch.,</strong><strong> of</strong><strong><em> Artemisia judaica</em></strong><strong> L.,<em> Eucalyptus camaldulensis</em> Dehnh. and <em>Majorana hortensis</em> Moench, were evaluated against </strong><strong>the rice weevil, <em>Sitophilus oryzae</em> (L.) and</strong><strong> the </strong><strong>rust red flour beetle,</strong><strong><em> Tribolium castaneum</em></strong><strong> (Herbst)</strong><strong> in stored wheat grains under laboratory conditions. The essential oils were applied on the wheat grains at rates of 0.5, 1 and 5 mg/g except for</strong><strong><em> M. microphylla</em></strong><strong> oil which was applied at lower rates of 0.01, 0.05 and 0.1 mg/g, because of its higher toxicity, to the two tested insect species. All tested essential oils had significant toxic effect to the two insects in sorted wheat. At all of the application rates, oils treatments showed significantly higher mortality of adults of both insects after one and two weeks compared with untreated wheat grains except for the treatments of the oil of </strong><strong><em>E. camaldulensis</em></strong><strong> at 0.5 mg/g and the oil <em>M. hortensis</em> at 0.5 and 1 mg/g with</strong><strong><em> S. oryzae</em></strong><strong>. The oil of</strong><strong><em> M. microphylla </em></strong><strong>was the most toxic one among the tested oils against both insects. The oil treatments also </strong><strong>significantly reduced progeny production of </strong><strong><em>S. oryzae</em></strong><strong>compared with the untreated control</strong><strong>. No</strong><strong> progeny emerged after 6 and 12 weeks</strong><strong> on treated wheat with</strong><strong><em> M. microphylla</em></strong><strong> oil at 0.5 mg/g and with<em> A. judaica</em> and<em> E. camaldulensis</em> oils at 5 mg/g. The treatments with tested essential oils significantly reduced grain weight loss, particularly at the higher application rates and all treatments with<em> M. microphylla</em> oil. These promising oils,<em> M. </em></strong><strong><em>microphylla</em></strong><strong> and <em>A. judaica</em>, could be recommended for use as part of</strong><strong> integrated pest management program of </strong><strong><em>S. oryzae</em></strong><strong> and</strong><strong><em> T. castaneum</em></strong><strong> in stored wheat. </strong><strong> </strong><strong> </strong>

<strong>The effects of salicylic acid, flax and caraway oils in either enhancing or inhibiting the lima bean plant’s defense against the feeding activity of cotton leafworm <em>Spodoptera littoralis</em> were tested. Treatments of salicylic acid as sodium salicylate (NaSA), flax and caraway oils were exogenously applied to lima bean seedlings. Antifeeding activity using cotton leafworm larvae for 48 hrs exposure as well as long-term effect of 12 days exposure were recorded. Plants treated with NaSA had encouraged the feeding ability by <em>Spodoptera</em> larvae that showed larger mass after 12 days of feeding with about 49.5% increase in larval growth rate. Flax oil with linolenic acid as the main component and the precursor of jasmonic acid (JA) increased the resistance of the host plants leading to an increased insect antifeeding activity and lower caterpillar growth rate by 39%. Treatment of caraway oil (23.5% carvone, 31.8% limonene) decreased the eating ability of the plant by caterpillars and hence inhibited larval growth rate by about 45% as well as increased average days to pupation with about 1.7 day. The present results indicate the importance of using elicitors of plant resistance in pest control programs that lead to activation of self induced resistance in treated plants. Flax oil and caraway oil have reasonable effects as potential inducers of lima bean plant resistance against cotton leafworm larvae.</strong>

<strong>The present study was conducted to investigate the effect of chicken manure at zero, 10 and 20 ton/fed.rates and biofertilization (phosphate dissolving bacteria PDB (<em>Bacillus megaterium </em>var. <em>phosphaticum</em> inoculation)) on growth, chemical composition, yield and sugar quality of two sugar beet varieties ('Lados' and 'T</strong><br /> <strong>WS 1436'). The experiment was carried out at South Tahrir Region – El-Behira during the two successive growing winter seasons of 2006/2007 and 2007/2008. The experimental design used was a split split plot with four replicates. All data showed that Lados gave the highly significant difference compared to TWS 1436 in all growth attributes and sugar beet quality parameters except for purity%, Na% and extractable sucrose%. Also, the results showed that with increasing chicken manure rates from control to 10 and 20 ton/fed. , the means of growth attributes and sugar beet quality parameters tended to increase significantly at the different sample dates in both seasons, except T.S.S.% and A.C. which were reduced significantly in both seasons. All growth attributes values at the different sample dates in both seasons were increased significantly by inoculation with phosphate dissolving bacteria. On the other hand, there was no significant difference in extractable sucrose%, A.C. and </strong><strong>µ</strong><strong>-amino-N between both varieties with and without PDB inoculation. In contrast, K, Na and T.S.S. percentages were decreased significantly with inoculation by PDB. In each plant varieties, the response of sugar beet plants without PDB to the increasing of chicken manure (OM) application was vigorous and highly significant. On the other hand, the sugar beet plants inoculated with the PDB had a slight difference and not significant at different OM rates in both varieties. In general, the bacteria have a significant effect when an organic matter level was very low. It can be concluded that inoculation with phosphate dissolving bacteria singly or application of chicken manure singly or combination of them had significantly increased all sugar beet growth attributes and quality parameters under the same conditions of this experiment. Also, Lados variety produced higher sugar beet growth attributes and quality parameters compared to the other variety TWS 1436</strong>

<strong>The objective of the present study was to investigate the effect of potassium rock (from the Eastern Desert of Egypt) and K-spraying as alternative potassium sources for the common potassium fertilizer in the presence of boron on sugar beet yield and juice quality. Two field experiments were carried out at Sakha Agricultural Research Station Farm during two winter seasons of 2007/2008 and 2008/2009. Split plot design was used with four replicates. The main plots assigned with two boron treatments: (1) without boron fertilization, and (2) spraying with boron solution two times (2.4 kg boric acid ha<sup>-1</sup>). The sub-plots were assigned with six potassium treatments: (1) without potassium fertilization, (2) application of 115 kg K<sub>2</sub>O ha<sup>-1</sup> as potassium sulphate 48%, (3) application of 57 kg K<sub>2</sub>O ha<sup>-1</sup> as potassium sulphate, (4) application of 115 kg K<sub>2</sub>O ha<sup>-1</sup> as K-rock (7.5% K<sub>2</sub>O), (5) application of 57 kg K<sub>2</sub>O ha<sup>-1</sup> as K-rock and (6) spraying with potassium 40% K<sub>2</sub>O(4.8 Lha<sup>-1</sup>). The obtained results can be summarized as: </strong><br /> <strong>Boron fertilization led to increase root yield by 15.6 and 13.9% in the first and second season, respectively and increased top yield by 33.6 and 38.1%, increased white sugar by 16.2 and 15.2%, increased sodium%, potassium%, quality % in the root, nitrogen % and K% in the leaves. The response to boron was less under K-rock source. It also increased sugar beet root and top yields. The highest root and white sugar yields were obtained with the K-rock. K-spraying had the high top yield and root and sugar yields under boron fertilization. </strong><br /> <strong>Potassium fertilization increased N, P and K% in the leaves, N and K in the roots and decreased available N in the soil after harvesting.</strong><br /> <strong>The obtained results showed that K-rock was the best source of potassium are present in Egypt. K-spraying in the suitable stage (critical periods) is a good helpful tool in correcting K-insufficiency.</strong>

<strong>Field experiments was carried out at the Experimental Farm of the Faculty of Agriculture (Saba Bacha) Alexandria University, during 2006/2007 and 2007/2008 winter seasons</strong><strong>. The aim of the present work was to evaluate the influence of N-fertilizer levels (30, 60 and 90 kg N/fed) applied alone or in conjunction with biofertilization (Rhizobacteria, nitrobein and VA-mycorrhizal fungi) on plant growth. Application of bio-fertilizers either alone or in combined with inorganic nitrogen fertilizer lead to significant increases in barley yield characters as compared with their respective control. However, this response differed according to type of bio-fertilizers. The results revealed that biofertilization performed significant improvement in plant productivity. The highest stimulatory effect and the maximum enhancement were exerted in plants treated with VA-mycorrhizal fungi and Nitrobein with 60 kg N/fed.</strong> <strong>The highest grain and straw yield, and the highest content of phosphorus and potassium in grain were obtained from the inoculation with VA-mycorrhizal fungi and N fertilizer rate of with 60 kg N/fed. treatment, while the highest N content in grain was obtained from the inoculation with VA-mycorrhizal fungi and 90kg N/fed.</strong> <strong>treatment. The combination between seed inoculation (N<sub>2</sub>-fixer) and reduced level of N-fertilizer (60 kg N/fed.) is recommended for reducing the excessive use of mineral N- fertilizers and hence minimizing the adverse environment and human health in agro ecosystems.</strong>

<strong>Since ancient times, cinnamon and propolis have been used as folk medicine with reported beneficial effects on various clinical conditions. According to previous studies cinnamon and propolis may have a positive effect on glycemic control in diabetes mellitus. The present investigation was assigned to study the effect of cinnamon , propolis ,or their combination on blood glucose levels, body weight, feed efficiency ratio, body weight gain, and relative organs’ weights in diabetic rats compared to normal rats. Thirty male albino rats were randomly divided into two main groups. The first group (n=6) was considered as negative control non diabetic rats (group 1). The other group of rats (24 rats) was subjected for intravenous injection with recrystalyzed alloxan to induce hyperglycemia. The diabetic rats were randomly assigned to four equal groups. (Group 2) alloxan induced, untreated rats (n=6) were chosen as positive control and the other three groups (groups 3,4 and5) were given stomach tube with cinnamon, propolis ,or mixture of cinnamon and propolis, respectively. The concentration of dry material were 10 mg cinnamon /ml, and 3 mg propolis /ml and mixture of 10 mg cinnamon and 3 mg propolis /ml for groups 3,4 and 5 respectively intragastrically once daily for 6 weeks(all groups were fed the basal diet). The results showed that treatment of diabetic rats with cinnamon, propolis and their combination led to decrease in serum glucose levels, compared with diabetic control group. The best treatment that improved serum glucose level was the combination of cinnamon &propolis.</strong><strong> Regarding BWG% and FER of rats, there were very highly significant differences between positive and negative control groups. Body weight of normal control group rats was significantly higher than the three treated groups as well as the FER. But there was no significant difference between CINN, PROP and CINN+PROP in BWG either in BWG% or FER. There were no significant differences among the treated groups in liver weights. Also, there were insignificant differences among the mean values of relative weights for kidney, heart and spleen in the treated groups (3,4and5) .While, these values were significantly lower than those of diabetic control group. For relative brain weight, normal control group showed significantly higher value compared to the other groups. While, there were insignificant differences among the relative brain weights in the treated groups (3, 4&5) which demonstrated significantly lower values compared to those in the positive control group. </strong><br /> e use of mineral N- fertilizers and hence minimizing the adverse environment and human health in agro ecosystems.<br /> <br />
