This study aimed at: 1. Identify the level of modernization between respondents in the Minufiya Governorate in Egypt, 2. Study the relationship between the farmers’ characteristics and level of modernity. The present study was conducted in two villages of Minufiya governorate which were Kafer Betibs from Tala districts and Met Faris Barket El- Sabah districts. A random sample of 100 farmers was chosen from each village. Data were collected by interviewing respondents through using a pretested questionnaire. It were statistically analyzed by using frequencies, percentages, simple correlation coefficients, T Scores, Z Scores and logistic regression analysis . The results revealed that 1. The highest proportion of farmers was between 28 and 60 years. Mean values for family size in the different study areas were 5.49, the main occupation of respondents was agriculture (60%) A large share of farmers (70%) received formal education, while (30%) of farmers did not receive any formal education. Farmers in the study area were small-scale farmers, it showed that the average size of land owned was one feddan, the average level of living was 12.19, the average annual gross farm income in the study area was 11362 L.E per household. All farmers in the study areas were members of the agricultural cooperative, which exist in all villages. Membership of these cooperatives was mandatory for those farmers who had reasonable access to it; 51.5% of farmers have a medium level of cosmopoliteness, 37% have a high level. More than 75% of farmers were falling in the medium level of communication with agricultural information, more than 65% of farmers had a medium level of aspiration, only 1.5% of farmers had a high level of aspiration, The highest proportion of farmers was a medium degree of filiations to community. 2. The results showed that non of the respondents from the sample size had a high level of agricultural modernity, 76.5% had a medium level and 23.5 % only had low level. 3.The coefficients of the logistic model used to investigate factors affecting the modernity of farmers. The chi-square test showed the level of significance of the parameters included in the model (at P <0.01). Modernity of farmers was correctly predicted for 77.5% of the farmers. The factors that contribute to modernity of farmers according to the Wald chi-square statistic were in order of importance: degree of affiliation, cosmopoliteness, family size, farm size, and aspiration level.

Field trials were conducted during 2005 and 2006 seasons at Minofia governorate to evaluate the effect of planting date of three cowpea cultivars on their infestation rate with cowpea pod borer, Etiella zienckenella. For each cowpea cultivar planted at each tested date, the numbers of bores and larvae were counted in green and dry pods as well as in dry seeds and the means were obtained to estimate the degree of insect infestations. Results indicated that, regardless the planting date in both seasons, Kream7 was the highest resistant cultivar to insect infestation followed by Kaha1 and then Kafr El Shikh1. On the other hand, regardless the cowpea cultivar, the rate of insect infestation was greatly reduced at the early plantation. Thus, selection of Kream7 cultivar and early plantation could be involved in reducing E. zinckenella infestation and subsequently increase the cowpea yield. These studies clearly demonstrated that several non-insecticidal approaches have great potential for cowpea pod borer Etiella zinckenella management. These approaches include some of integrated pest management strategies which can effectively prevent or reduce infestation

Fusarium wilt disease is one of the major plant diseases that affect tomato production. The effects of neem (Azadirachta indica) and willow (Salix babylonica) aqueous extracts on fusarium wilt disease in tomato seedlings were investigated. Four weeks old tomato seedlings were treated with 10% of either neem and willow aqueous extracts and then infected with Fusarium oxysporum after 4 days of treatment. The results showed that the percentage of disease incidence was increased in non treated tomato seedlings in time dependent manner and reached the maximum level (65%) after 6 weeks of infection. Treatments of tomato plants with neem and willow aqueous extracts reduced the percentage of disease incidence to the level of 25.5% and 27.8% after 6 weeks of infection respectively. The results show that infection of tomato seedling with Fusarium oxysporum led to many morphological and biochemical changes including, reducing the growth of tomato shoot and root, increasing the level of lipid peroxidation and marked increase in the activities of antioxidant defensive enzyme i.e. POX, CAT, and SOD. Treatment with neem and willow aqueous extracts significantly exhibited a growth promotion of tomato shoot and root in infected or non infected seedling. Moreover, application of neem and willow aqueous extracts with fusarium, significantly reduce the level of lipid peroxidation and induce high activities of antioxidant defensive enzymes after 3 and 7 days of infection. Electrophoretic pattern of POX demonstrated that Fusarium oxysporum caused up regulation of several POX isoenzymes. It could be concluded that neem and willow aqueous extracts reduced the disease incidence of fusarium wilt in tomato seedlings by increasing the activities of antioxidant defensive enzymes and decreasing the level of lipid peroxidation.

2011
A.L. Iskander | Khald E.M. | Sheta A.S.
Understanding the sorption process in natural zeolite and bentonite is necessary for effective utilization of these minerals as nutrient adsorbents and on the other side for controlling release of plant nutrients. This research was undertaken to characterize the ability of natural zeolite and bentonite minerals to adsorb and release zinc and manganese. The potentials for sorption of these ions were evaluated by applying the Langmuir and Freundlich equations. The results showed that Langmuir constant [maximum adsorption (b mmol kg-1)] of both Zn and Mn were for bentonite > zeolite While the [binding strength values (k in L.mmol-1)] for zeolite > bentonite Zn in case of zeolite showed the lowest desorbed percentage particularly at high levels of sorbed Zn. Only, 74.7 % is readily extractable by DTPA after three successive extractions leaving, 25.3 % Zn retained by the mineral. In case of bentonite, 82.26 % of sorbed Zn is readily extractable by DTPA after three successive extractions leaving, 17.74 % Zn retained by the mineral. In case of Mn, 84.63% of Mn sorbed by zeolite is readily extractable by DTPA after three successive extractions leaving, 15.37% Mn retained by the mineral. In case of bentonite, 89.79 % of adsorbed Mn is readily extractable by DTPA after three successive extractions leaving, 10.21 % Mn retained by the mineral. This finding may reflect clearly the possibility of using natural zeolite and bentonite as a slow release fertilizer for Zn and Mn and on the other hand preventing soil pollution with heavy metals.

Among 17 fungal isolates isolated from soil of El-hawia, El-hada, El-kaym and Karwa in Taif governorate in Saudi Arabia, two isolates showed high efficacy in producing cellulases enzymes. They were identified to be Alternaria alternata and Aspergillus wentii. Some factors such as carbon and wheat bran as a raw material, nitrogen, pH and incubation temperature were investigated. Results indicated that glucose and cellulose were the most effective as a carbon source while, urea was the best nitrogen source for cellulases production. Initial pH 5.0 and incubation temperatures at 25 or 35ºC achieved high cellulases production.
