A field experiment was conduced during the summer seasons of 2005 and 2006 at Disuq district, Kafr El-Sheikh Governorate to study the combined effect of inoculation with Halex-2 (as biofertilizer) and mineral nitrogen levels on cowpea yield and their net return.Split plot design was used with four replicates. The main plots were assigned by two treatments of uninoculated (control), and inoculated with Halex-2. Whereas, the sub-plots were assigned by five N levels (0, 10, 20, 30 and 40 kg N fed -1 ). Four polynomial quadratic equations were established to show the following results:1. The maximum and optimum N rates were decreased as Halex-2 used in the two seasons. 2. The maximum and optimum cowpea yields were increased as Halex-2 used in the two seasons. 3. The highest maximum yield (1413.2 kg fed -1 ), the highest total value of yield (7065.0 L.E fed -1 ) and the highest return of bio and N fertilizer (2936.6 LE fed -1 ) were obtained as Halex-2 used in the first season. 4. The average of efficiency and the efficiency of nitrogen fertilizer at optimum rate were increased as Halex-2 used. 5. The soil nitrogen content during plant growth (Xs) was increased as Halex-2 added. 6. The contribution of soil N was increased as Halex-2 used in the two seasons. 7. The contribution of N fertilizer was increased as N levels increased in the two seasons.

This investigation carried out in cooperation work between Horticulture Department, Faculty of Agriculture, Kafr El-Sheikh and Horticulture Research Institute during the period of 2001 to 2010 through two stages. The first stage: Six strains of okra were obtained after six generations of inbreeding and selection from the local cultivars. The six selected strains and the original cultivars were evaluated during the summer season of 2006 for yield and horticultural characteristics. Evaluation results indicated that the, Strain No. 1 had the lowest values of vegetative traits and it produced the largest values of early and total yield as a number and weight of pods, therefore, this strain was chosen as a new cultivar under name of Sakha-1 after produced their seeds in isolated area in two successive years. The second stage: The new cultivar and two commercial cultivars, i.e., Balady Green and Sabahia-1 cultivars were evaluated in summer seasons of 2009 and 2010 in the Experimental Farm of Sakha Agricultural Research Station. The new cultivar Skha-1 surpassed the Balady Green and Sabahia-1 cultivars for early and total yield as a number and weight of pods and pod quality.

Most of farmers in Kafr El-Sheikh area accustomed to grow pea as cash vegetable crop in the short period lied between summer and winter crops before growing summer season and they need to control weeds in such crop. Thus, this investigation was carried to study the response of pea plant Master B, variety and their associated weed in two field experiments were during 2013/2014 and 2014/2015 winter seasons at Sakha Horticultural Research Station Farm, Kafr El-Sheikh Governorate. A split plot in a randomized complete blocks design with four replications was used. Where the response of pea plants, two inoculated with the rhizobium bacteria and some weed control treatments. The main plots included rhizobium bacteria inoculation and uninoculated control, the sub plots included eight weed control treatments i.e pendimethalin at 1.7L/fed, pendimethalin at 1.25L/fed plus hand hoeing once, pendimethalin at 1.0 L/fed plus hand hoeing twice; butralin at 2.5L/fed; butralin at 2.00 L/fed plus hand hoeing once; butralin at 1.0 L/fed plus hand hoeing twice, hand hoeing twice and untreaded control. The main findings in this study were as follow: Rhizobial inoculation with pea seeds caused significant increases in both seasons in number of nodules plant-1 , fresh, dry weight of nodules plant-1 and increased yield ton/fed by (

This investigation was conducted during two successive seasons of 2019 and 2020 on 36 years old trees of Manfalouty pomegranate cultivar cultivated in a clay loam soil at the experimental orchard of Faculty of Agriculture, Assiut University, Assiut Governorate, for studying the effect of four irrigation methods: flood surface (control), terraces, ring and drip irrigation on vegetative growth and fruiting, yield, fruit physical and chemical properties and water use efficiency (WUE).The obtained results indicated that, use modified flood irrigation (terraces), ring or drip irrigation significantly increased shoot length, number of leaves per shoot and leaf area. Using drip or modified irrigation recorded the highest water use efficiency (WUE). It is clear from the current results the importance of irrigation via modified surface irrigation (terraces) which leads to improve the growth and nutritional status of trees, hence increase the packable yield. In addition, such irrigation methods increase the water use efficiency and reduce the cost of production and avoid problems with drip irrigation.
