Twenty growing crossbred male lambs (¾ chios. ¼ ossimi and ½ chios. ½ ossimi) of 15.25 ± 2.00 kg initial average body weight and three months old were divided into four groups. All groups were fed on concentrate feed mixture plus 1% of live body weight wheat straw for 169 days. Four levels (zero, 200g, 400g and 600g) of leucaena hay were used. Final weight and carcass traits were evaluated. Color (L, a, b), proximate composition, pH, acidity, expressible water, water holding capacity, cooking loss, amino acid and minerals contents of meat were determined. Sensory evaluation of cooked meat was also evaluated.The results revealed that, Hindquarter, shoulder, and sets weight were significantly (p ≤ 0.05) different. Moisture, protein, fat and ash content of fresh meat were ranged from 73.72 to 76.23%, 20.06 to 20.80 %, 2.41 to 4.12% and 1.01 to 1.08%, respectively. Expressible water, water holding capacity and pH were significantly (p ≤ 0.05) different. No significant (p ≤ 0.05) differences were found in color (L, a, b), acidity and cooking loss of meat. Amino acids and minerals contents of all meat samples were varied. Cooked meat of group four had the highest scores of tenderness, juiciness, flavor and over all acceptability 4.6, 4.5, 4.4 and 4.5, respectively. This study suggested that the leucaena hay is suitable for lamb feeding. Produced lamb meat had high chemical and sensory quality.

This study was conducted during two successive seasons (2016/2017 first ratoon and 2017/2018 second ratoon) of Williams banana plants. The plants grown in a private banana orchard, where clay loam soil under flood irrigation system, at 3.5x3.5m apart located at Nakada district, Quena Governorate, Egypt. Forty eight stools each containing three plants were chosen to evaluate the effect of yeast applied as soil drench and spraying ascorbic acid (V.C) on growth, yield and fruit quality. These treatments were arranged in a randomized complete block design in split plot arrangement with three replicates. The obtained results could be summarized as follows. Ascorbic acid spraying significantly increased the length and circumference of pseudostem, leaf area and total leaf area/plant as well as percentage of N, P and K of leaves compared to unsprayed ones. Also, these treatments significantly increased the yield components and improved the fruit quality compared to unsprayed ones. Yeast application was very effective in enhancing all growth aspects, yield and fruit characteristics compared to untreated ones. All combinations of ascorbic acid spraying on the yeast treated plants resulted in a significant increament in all growth aspects, yield components and fruit quality as compared to check treatments. The best results regarding the growth and fruiting were obtained with ascorbic acid spraying (at 200 ppm) accompanied with yeast application (at 40 g/plant) compared to other tested treatments. It is evident from the foregoing results that the application yeast at 40 g/plant and ascorbic acid at 200 ppm application four times during growth season (April, June, August & October), singly or in combination improved the growth and yield of Williams banana plants.

Grapevine fertilization is one of the most sensitive practices, particularly interested in management package. Three years study (2004, 2005 & 2006) has been conducted in a private vineyard located at El-Khatatba region, Menofia Governorate to investigate the effect of ureaform (UF) as a slow release nitrogen fertilizer and ammonium nitrate (AN) as an ordinary one with or without application of farmyard manure (FYM) on yield and quality parameters of Thompson seedless grapes (Vitis Vinifera L.).Results indicate that no significant effects for the different treatments on the morphological characters have been observed except that of leaf area which has shown clear response to both UF treatment rates and FYM application. Also, it is observed that such character values were superior in the 3 rd year to those of 2 nd one. All treatments have given good quality grape yield. However, it is observed some inferiority concerning total sugar and total soluble solids as well as high acidity in condition of available nitrogen glut expected and due to high nitrogen rates or FYM application.In 2 nd year, it is observed positive effect for each FYM and UF treatment on cluster weight, yield/ vine and yield/ fed. The UF rate of 96 kg N/fed without FYM and 48 kg N/ fed with adding FYM have been the most superior. In the 3 rd year, No effective for FYM application on the yield or their components has been marked, yet on the contrary, the nitrogen treatments without FYM application have given the most yield, it is also observed that the treatments tagged (+) have given yield more than those tagged (*) regardless fertilizer type or rate.Concerning the economic evaluation, net return and investment factor (IF) of UF treatments has been superior to those of AN treatment in case of no adding FYM, the contrary has been true in case of FYM application. In the 2 nd year, it is illustrated that the optimum rates to fulfill the maximum profitability have been 96 kg N/ fed. without FYM application and 48 kg N/ fed. with FYM application. In the 3 rd year, and because of its yield has been more than that of 2 nd one, its net return has been so much comparing with those of 2 nd one.Generally, the treatments have not received N-fertilizer in the 3 rd year has been the most profitability although its net return has been less than those received Nfertilizer. This means that the highest yield does not mean the highest profitability. However, still the rate 96 kg N/ fed. without FYM application and 48 kg N/ fed. with FYM application have been the most profitability.
