EVALUATION OF SOME WEED CONTROL TREATMENTS ON DODDER (Cuscuta planiflora), TEN CONTROL IN EGYPTIAN CLOVER (Trifolium alexandrinum L.)
I.
Soliman
Two field experiments were conducted during the two successive seasons of 2006/07 and 2007/08 at Sakha Agriculture Research Station, Egypt, to investigate the efficacy of some herbicides i.e. Buralin, Roundup, Herbazed and Herphosate in addition to the hand combing for controlling dodder weed (Cuscuta planiflora), Ten. and their effects on some growth characters and seed yield of clover plants (Trifolium alexandrinum L.).
Results indicated that Roundup herbicide showed good control of dodder followed by Herbazed, Butralin and Herphosate treatments. Also, showed that dodder weed caused a great decrease in plant height, fresh, dry weight and seed yield of clover plants. Also, the results indicated that the hand combining treatment was not enough in dodder control, but it used only as a factor in control programs.
Clover plants infested with dodder showed the lowest chlorophyll a, b and highest carotene contents. Data also, cleared that different herbicide treatments showed least decreased on chlorophyll a and b and increased carotene content compared to un-infested and untreated plants. Data also, revealed that most herbicidal treatments slightly decreased protein content of clover plants. These results indicate that under heavy invested soil with dodder, it is possible to used of herbicides i.e. butralin, Roundup, Herbazed and Herphosate. These practices gave the highest reduction in dodder injury and increased clover yield and its components.

It is imperative to define precisely the optimal plant population of a variety in order to maximize sugar production at minimum cost. This study was carried out during 2005/2006 and 2006/2007 seasoNS at Mallawi Agric. Res., Station, El-Minia Governorate, Egypt, to investigate the changes in growth, yield and juice quality characters of some promising sugarcane varieties, i.e. G.99-103, G.98-28 and Phil.8013, compared to the commercial variety G.T.54-9 at different row spacing; 80, 100 and 120cm and seed rates (9 and 12- buds/m long) for plant cane.
The collected data pointed out that, there were significant differences in stalk length, total soluble solids (TSS), sucrose, purity, reducing sugars, sugar recovery percentages, millable cane yieldand recoverable sugar yield (ton/fed)with increasing row spacings from 80 to 100 and 120 cm in the two growing seasons.
Meanwhile, the evaluated sugarcane varieties differed significantly in all studied characters in both seasoNS. Increasing seed rates from 9 to 12-buds/m under the three tested row spacing caused significant difference in stalk length, stalk diameter, and.
Generally it is concluded that, G.99-103 variety planted in 100 cm row spacing and 12-buds/m of seed rates (48,000 buds/fed) are preferable under El-Minia for production sugarcane because it gave the highest values of millable cane (59.53 ton/fed) and recoverable sugar yield (6.28 ton/fed ).

Two field experiments were conducted in 2003/2004 and 2004/2005 seasons in Gelbana village, El-Kantra Shark, Sinai to study the effect of three sowing dates (30 September, 15 October and 5 November) and two harvesting dates ( 180 and 200 days after sowing) on productivity of five sugar beet varieties ( Top, Kawemira, Gloria, Pleno and Farida ) under sprinkler and drip irrigation systems.
Sowing sugar beet under sprinkler or drip irrigation systems, at middle October recorded the highest root fresh weight/plant, root diameter and root length. Also, when sugar beet sown on 15 October, root and sugar yields/fed attained the highest values. On the other hand, the latest sowing date, namely 5 November produced the highest values of top fresh weight/plant, sucrose %, purity % and top yield/fed.
Delaying harvest sugar beet from 180 till 200 days after sowing improved significantly the individual root characters and juice quality, as well as increased significantly root and sugar yields/fed. That held true under both irrigation systems in the two growing seasons.
It was proved that sugar beet varieties differed under each irrigation system, where, Pleno cv. gave the highest values of root and top fresh weight/plant and root diameter under sprinkler irrigation, while Kawemira and Top cvs. were the best under drip irrigation. Concerning root and sugar yield as well as juice quality, Pleno, Kawemira and Top cvs. were the best under both irrigation systems.

Two field experiments were conducted in 2003\2004 and 2004\2005 seasons in Gelbana village, El-Kantra Shark, Sinai to study the effect of transplants dates, namely 15, 25 and 35 days from sowing nursery compared with direct seeding (control) on productivity of five sugar beet varieties, namely Top, Kawemira, Gloria, Pleno and Farida. Results showed that both direct seeding and transplant 25 days age produced the highest root yield without significant difference between them. Also, direct seeding did not differ significantly from transplants 15 or 25 days age concerning sugar yield. Slight but significant differences among the five studied varieties were found in root yield, and Farida cv. recorded the highest roots and sugar yields/fad.

Two field experiments were conducted during two successive seasons of 2007 and 2008 in Meit Nagy Village, Meit Ghamr, Dakahlia Governorate, Egypt, to study the effect of some pre-or post-emergence herbicides either alone or accompanied with hoeing on soybean yield and its components and associated weeds. The results showed that the best treatments in controlling the annual bread leaves, annual grasses and total annual weeds throughout the vegetative period of soybean plants were : The pre-emergence application of Pendimethalin at 0.425 kg a.i./fed or Metribuzin at 0.140 kg a.i./fed followed by one hoeing (21 days after sowing) or post-emergence application of Bentazon at 0.180 kg a.i./fed preceded by one hoeing (21 days after sowing), or using hand hoeing twice (21 and 35 days after sowing) compared with single herbicidal treatments. Treatment of Pendimethalin at 0.425 kg a.i./fed followed by one hoeing improved the growth of soybean plants and resulting in the tallest plants, highest number of pods/plant, number of seeds/pod, seed index, seed yield/plant and per feddan and the highest oil % in the seeds as well as seed protein percentage compared to other weed control treatments.

This study was carried out during the two successive summer seasons of 2008 and 2009 at the Experimental Farm of Environmental Studies and Research Institute, Minufiya University, Sadat City, to evaluate the influence of the yield and yield attributes of groundnut to four gypsum applications (0, 250, 500 and 750 kg/fed) in a split-plot design using (Giza-kaem, Giza-4 and Giza-5) peanut cultivars of four replications. Other nutrients wereapplied uniformly.
The results from this experiment show that adding gypsum with the rate of 500 kg / fed increased significantly pods weight / plant, 100- seed weight, shelling %, oil seed % total protein and pod yield / plant.
0n the other hand Giza 5 cultivar was superior than Giza 4 and Giza kaem in plant height, number of branches / plant, number of pods / plant, 100-pod weight, shelling % oil seed %, total protein and pod yield kg /fed.
The interaction between gypsum frequency and cultivars had significant effect on pod yield / fed. The highest pod yield / fed were produced by using Giza 5 and gypsum with the rate of 500 kg / fed.
Finally, it could be concluded that the superior interaction treatments concerning yield and its components were the cultivated peanut plants Giza 5 variety when received 500 kg gypsum/fed with all other treatments.

Field experiments were carried out to investigate the effect of silicon (500 and 1000 ppm SiO2) or Putrescine (1 and 2 ppm) sprayed twice at 45 and 60 days after planting on the growth, yield and chemical composition of the two local cultivars of globe artichoke plant in Egypt i.e., Balady and French (Hyrious) cultivars. Generally, French (Hyrious) cultivar which sprayed by silicon (1000 ppm SiO2) was the best treatment on growth characters and yield components and recorded the highest values of early and total yield increases in the two successive seasons when compared with non- sprayed plants, followed by French (Hyrious) cultivar sprayed by putrescine (1 ppm). French cultivar sprayed by silicon (1000 ppm SiO2) was the best for significant increased in P concentration of leaves and it was the best interaction treatment led to increase on total sugar concentration in the tow successive seasons when compared with control- untreated plants followed by French cultivar sprayed by putrescine (2 ppm). While, French cultivar sprayed by putrescine (2 ppm) followed French cultivar with sprayed by silicon (1000 ppm SiO2) were the best treatments which caused significant increased in total free amino acids in the two successive seasons. But French cultivar sprayed by putrescine at the rate of (1ppm) was the best caused a significant decreased in total soluble phenol when compared with control plants of both successive seasons followed by French cultivar sprayed by silicon (1000 ppm SiO2).The higher level of silicon caused a significant increased in IAA and CK while, the lower level led to significant increased in GA3 and CK.

DEVELOPMENT OF SOME HIGH YIELDING RICE LINES TOLERANT TO DROUGHT STRESS CONDITIONS
A.
Abd Allah
In Egypt, rice is one of the major water consuming crops and continuous flooding is the most common methods for irrigation. The water requirement for the rice crop cause nowadays an acute problem because of the limited irrigation water available from the River Nile. The present study was carried out to develop new promising lines produce more rice with less water to be grown to the drought affected areas due to the shortage of irrigation water and at the end of the terminals which receives irrigation water irregularly. Some promising lines were derived from IET 1444/ Sakha 102, Sakha 101 / IR 65600 and Sakha 101 / Gaori populations. Attentions were paid to the traits more associated with drought tolerance among segregants, to identify genotypes that confer drought resistance through selection procedures. The progenies from each cross were advanced under drought conditions from F2 generation using the pedigree method technique until F6 generation. The best ten selected lines from Fn generation were promoted to the yield trial experiments during 2007 and 2008 seasons. Randomized complete block design with three replications was used. The amount of irrigation water applied was determined by using flow meter. In 2009 season, the lines were evaluated under different irrigation intervals (irrigation every four, eight and twelve days) to test their yield potential. These lines were found to be tolerant to drought conditions at different growth stages i.e. early and late vegetative stage, reproductive and ripening stage. These lines proved to possess useful traits associated with drought tolerance such as early maturity, medium tillering ability, intermediate plant height, deep and thick roots, high root volume, high root: shoot ratio, plasticity in leaf rolling and unrolling, in addition to high water use efficiency. Water saving ranged 50-55 % as compared to continuous submergence, with a rice yield of 7-9 tons/ ha. So, by using such lines, the total water requirements will be significantly reduced without significant reduction in the yield. Also these lines can be used as donor parents at reproductive stage to solve the problem of a lack of the donor parents in breeding rice for drought tolerance.

Two field experiments were carried out at the Agric. Experimental Station, Faculty of Agric., Mansoura University, Egypt during the two growing seasons of 2007-2008 and 2008-2009, aiming to evaluate botanically two newly tomato genotypes grown under shading and wastewater of El-Delta company of fertilizers and Talkha electricity generate mixed with sewage of the vicinity villages, at Dakahlia Governorate, Egypt. The data indicated that Cheyenne (e 448) genotypes recoded an increase in all growth characters studied compared with Gs 12 at different growth stages in both growing seasons. However, in both genotypes, Plant height, numbers of internodes, leaves and branches on the main stem, as well as, fresh and dry weight of the shoot system were increased significantly due to wastewater application at 50% level whereas decreased insignificantly at 100% level. Shading agent seemed to have a stimulating effect on different growth characters of the two tomato genotypes under the present investigation compared with the control
The interaction treatments indicated that shading enabled the developing tomato plants to withstand, wastewater at 100% level .The "S" or sigmoide growth curve was detected in both tomato genotypes studied during the two tomato growing seasons. The highest rate of increase was detected between the 1st and 2nd sampling date.
Genotype (2) bloomed earlier than genotype (1); by about 7-10 days in the first and second seasons respectively and showed shorter growing period and earlier maturation than genotype.(1). overall all treatments examined. However, irrigation with Wastewater at 50% level increased whereas shading enlowered the period elapsed from transplanting to flowering in both tomato genotypes. Similarly, wastewater at 100% level delaying flowering but only with genotype (1) by about 15-19 days and at 100% hasten following by about 12-15 days in the first and second seasons respectively. Shading with wastewater at 100% has no significant effect in this respect
