Two field trials were conducted during 2009/2010 and 2010/2011 seasons, in Tamia District, El-Fayoum Governorate, Egypt, to study the effect of two cease irrigation before harvest periods (10 and 20 days) and three spaces between hills (15, 20 and 25 cm) on performance of three varieties (Pleno, Samba and Lola). Cease irrigation 10 days before harvest significantly increased root and top fresh weight, while cease irrigation 20 days before harvest significantly increased sugar yield/fed, percentages of sucrose, TSS and purity. Root and sugar yield /fed, and sucrose% were significantly increased with reducing spacing hills. Spacing of 15 to 20 cm between hills had the best quality traits. Samba variety had the highest values of root and sugar yields /fed as will as sucrose and purity percentages. Ceasing irrigation and varieties interaction had a significant effect on quality traits, as well as root and sugar yields/fed. Under this study sugar beet can be cultivated on 20 cmhill spacing with cease irrigation at 20 days before harvesting to maximize sucrose% as well as yields of root and sugar yields/fed.
Two field experiments were conducted at Agric. Exp. Res. Sta., Fac. Agric., Cairo Univ., during 2011/2012and 2012/2013 seasons to study the effect of five foliar application of micronutrients (F1: control "spraying water only, F2: Fe+ Mn at 5 g L -1 , F3: Fe+Zn at 5g L -1 , F4: Mn+Zn at 5 g L -1 and F5: Fe+Mn+Zn at 5 g L -1 ) on yield and seed quality of three cultivars of faba bean (Giza 3, Sakha 1 and Giza 716). A spilt plot design in a randomized complete blocks arrangement with three replications was used. Micronutrients treatments were randomly assigned for main plots while, faba bean cultivars were randomly arranged for sub plots. Results showed that foliar application treatments significantly increased all yield traits and protein content compared with control treatment in both seasons. Spraying Fe+Mn+Zn mixture produced the greatest plant height (103.3 and 107.3 cm), number of branches plant -1 (3.46 and 3.60), number of pods plant -1 (18.40 and 18.80), pods weight plant -1 (38.67 and 40.03 g) , number of seeds pod -1 (3.39 and 3.42), 100-seed weight (65.53 and 65.77 g), seed yield plant -1 (35.80 and 37.90 g), seed yield (1746 and 1786 kg/fed.), straw yield (4536 and 4618 kg/fed.) , biological yield (6283 and 6405 kg/fed.) , harvest index (27.97 and 28.55%) and protein content (27.97 and 28.55 %) in both seasons, respectively. Giza 3 cultivars was superior in yield traits and protein content followed by Sakha 1 cultivar. However, Giza 716 cultivar gave the lowest values of yield traits and protein content in both seasons.
Two field experiments were conducted at Agric. Exp. Res. Sta., Fac. Agric., Cairo Univ., during 2011/2012and 2012/2013 seasons to study the effect of five irrigation treatments (I1; normal irrigation "control" ; I2: skipping the second irrigation ; I3: skipping the third irrigation; I4: skipping the fourth irrigation and I5: skipping the fifth irrigation) on yield and seed quality of three cultivars of faba bean (Giza 3, Nubaria 1 and Sakha 3 ). A spilt plot design in a randomized complete blocks arrangement with three replications was used to conduct all trials. Irrigation treatments were randomly assigned for main plots while, faba bean cultivars were randomly arranged for sub plots. Results showed that skipping irrigation at various growth stages had significant effect on all studied traits in both seasons. Skipping the fourth or the fifth irrigation gave the greatest reduction in all yield traits except, seed protein content which increased in both seasons compared with other irrigation treatments. Regarding faba bean cultivars, differences among the three faba bean cultivars were significant except, number of pods plant -1 , pods weight -1 , number of seeds pod -1 and harvest index (%) in both seasons. Giza 3 cultivar gave the highest values all yield traits and seed protein content (%) followed by Nubaria 1. However, Sakha 3 cultivar gave the lowest value of all yield traits and seed protein content (%) in both seasons. For interaction between irrigation regime and faba bean cultivars, all faba bean cultivars were affected by skipping irrigation in both seasons. Giza 3 cultivars was more tolerant to skipping irrigation followed by Nubaria 1 however, Sakha 3 was more sensitive to drought stress.
Two field experiments were carried out during 2013/2014 and 2014/2015 winter seasons at Agric. Res. Stat., Fac. Agric., Cairo Univ. Giza, Egypt to study the effect of two seeding rates i.e.50 and 65 kg seed/ faddan (4200 m 2) and seven treatments of N, P and K fertilizers with or without Cerealin inoculation on wheat growth, grain yield and its components. These seven treatments were T1 (0-0-0 NPK), T 2 (50-30-24 NPK), T 3 (65-37.5-36 NPK), T 4 (80-45-48 NPK), T 5 (T 2 + Cerealin), T 6 (T 3 + Cerealin), and T 7 (T 4 + Cerealin). A split plot design in randomized complete blocks arrangement with three replications was used. Seeding rates were randomly assigned for the main plots while, fertilizer treatments were randomly arranged for the sub plots. The obtained results showed that seeding rates had no significant effect on all yield attributes except, number of shoots m-2 , number of grains spikes-1 in 2013/2014 season, number of shoots m-2 , number of spikes m-2 , straw yield /faddan and harvest index in 2013/2014 season. Mineral NPK fertilizers with bio-fertilizer (Cerealin) had significant effect on yield and its components except, spike length in both seasons. Grain, straw and biological yields and its attributes i.e. plant height, number of shoots m-2 , number of spikes m-2 , number of grains spike-1 , grains weight spike-1 , 1000-grain weight were significantly increased by adding bio-fertilizer compared to none adding in both seasons, respectively. Adding 75% of recommended dose of NPK mineral fertilizer combined with Cerealin inoculation resulted in significant increment in plant height, number of shoots m-2 , number of spikes m-2 , number of grains spike-1 , grains weight spike-1 , 1000-grain weight, grain, straw and biological yields as well as harvest index compared with other combination treatments. The interaction between seeding rate and fertilizer treatments was significant for all characters under study in both seasons. The highest grain yield (4.31 and 4.07 ton / faddan) in both seasons, respectively was recorded by sowing 65 kg seed faddan-1 with adding 65 kg N + 37.5 kg P 2 O 5 + 36 kg K 2 O + Cerealin inoculation compared with other tested treatments.
