“…In addition, continuous cropping of soybean causes an increase in organic compound (sugars, amino acids, organic acids) content in soil and promotes the growth of root rot pathogens [13]. Most sterilization techniques for killing spores indirectly leads to the dominance of fungal colonies in continuously cropped soils [18,19]. …”

Recent studies have shown that continuous cropping in soybean causes substantial changes to the microbial community in rhizosphere soil. In this study, we investigated the effects of continuous cropping for various time periods on the diversity of rhizosphere soil arbuscular mycorrhizal (AM) fungi in various soybean cultivars at the branching stage. The soybean cultivars Heinong 37 (an intermediate cultivar), Heinong 44 (a high-fat cultivar) and Heinong 48 (a high-protein cultivar) were seeded in a field and continuously cropped for two or three years. We analyzed the diversity of rhizosphere soil AM fungi of these soybean plants at the branching stage using morphological and denaturing gradient gel electrophoresis (DGGE) techniques. The clustering analysis of unweighted pair-group method with arithmetic averages (UPGMA) was then used to investigate the AM fungal community shifts. The results showed that increasing the number of years of continuous cropping can improve the colonization rate of AM fungi in different soybean cultivars at the branching stage. The dominant AM fungi in the experimental fields were Funneliformismosseae and Glomus spp. The number of years of continuous cropping and the soybean cultivar both had obvious effects on the diversity of AM fungi, which was consistent with the results of colonization rate analysis. This study establishes a basis for screening dominant AM fungi of soybean. In addition, the results of this study may be useful for the development of AM fungal inoculants.

The present investigation was conducted in the farm of Sakha Agricultural Research Station, Kafr El-Sheikh Governorate during 2015/ 16 and 2016/ 17 to determine the influence of sowing dates on the major piercing-sucking insect pests which infested faba bean and soybean plants. On faba bean plants, Emposca spp. ranked in the first category with the highest average number in October cultivated (60. 35 ± 12.08 and 89.55 ± 11.29 indiv.) followed by M. persicae (37.30 ± 12.08 and 61.85 ± 12.74 indiv.) in both seasons, respectively. Meanwhile, in November implanted A. craccoivora was recorded the highest average number (72.85 ± 23.86 and 270.45 ± 80.49 indiv.) followed by Emposca spp. (51.15 ± 7.76 and 69.25 ± 12.73 indiv.) in the two successive seasons, respectively. While, in December grown Emposca spp. came in the first category (53.30 ± 10.90 indiv.) in the first season and M. persicae observed the first category (63.35 ± 10.95 indiv.) during the second season. P. solenopsis was found the lowest average number in the different planting dates at the two successive seasons. On the other side, on soybean plants, A. gossypii arranged in the first category in the three plantations and observed the highest average number in the June plantation with values (

“…The identification of the most suitable planting date for sugar beet is pivotal for sustainable production and cultivation of sugar beet (Curcic et al 2018). However, taking into account some other influencing factors such as pests' activity and marketing and industrial-related considerations, the most suitable planting date is defined as the time of sowing that enables the crop to achieve the required heat units without excessive heat-or cold-shocks (Abdallah 2012;Alsadon 2002). Plant density and geometrical distribution of plants (bed width and hill spacing), which are crucial for the conservation of water and the efficient use of fertilizers, have to be taken into account for improving the productivity and quality of sugar beet.…”

Sugar beet is the most important sugar crop that can be grown commercially in a wide variety of temperate regions. The beet sugar industry in the tropical and subtropical regions, which are mostly developing countries is growing as an important component of sugar production. A field experiment was conducted at Delta Sugar Company Research Farm, El-Hamool, Kafr El-Sheikh, Egypt to evaluate the response of sugar beet varieties to inter-and intra-row distances. The analysis of variance (ANOVA) revealed significant effects of inter-and intra-row distances on all studied traits, i.e., sucrose content (Pol%), Na%, K%, α-amino-N%, quality index (Qz)%, root yield (RY), recoverable sugar (RS)%, recoverable sugar yield (RSY), sugar loss (SL)% and sugar loss yield (SLY) either in one or both growing seasons except for the effect of inter-row planting distances on Na% and loss sugar yield in both growing seasons. The results revealed that increasing the inter-row planting distance from 50 to 60 cm led to a significant reduction in sucrose content, Na%, RY, RS% and RSY. However, increasing the inter-row planting distance from 50 to 60 cm is associated with a significant reduction in the Qz%, RS%, SL% and SLY. Increasing the intra-row planting distances from 10 to 15 cm led to a significant reduction in sucrose%, Na%, Qz% and RS%. Additionally, significant variations in all studied traits were observed among varieties.The interactions between the studies factors and varieties exhibited significant effects on all studied traits. Planting the variety Garrot at 15 and 50 cm intraand inter-row distances produced the highest Qz%, RY and RSY. The lowest SLY resulted from planting the sugar beet variety Husam at 10 and 60 cm intra-and inter-row planting distances. The results of the present study of great importance for a sustainable production of sugar beet in Egypt.
