The Arid Regions

Eleven onion (Allium cepa L.) cultivars were selected to evaluate their yield performance under the arid conditions of the Riyadh area in the Central region of Saudi Arabia during the 1996–97 and 1997–98 growing seasons. The selected cultivars were: Colossal PVP 234, Contessa, Dorado, Red Creole, Ring Master, Rio Sultan, RioTalat, Texas Grano 502, Texas Early Grano 502, Und Grande and Yellow Spanish. Yield (ton/ha) and yield attributes such as bulb diameter, length, weight and dry matter were assessed. Transplants grown in plastic trays for 45 days under greenhouse conditions were transplanted in the field on 7 Jan. 1997 and on 29 Dec. 1997 and harvesting was carried out on 19 May 1997 and on 15 May 1998 for the first and second season, respectively. Significant differences were observed between cultivars and among growing seasons, with significant interaction for yield and bulb weight. The top high yielding cultivars in the first season were Und Grande, Texas Early Grano 502, Colossal PVP 234, Contessa and Dorado. In the second season, Dorado, Red Creole, Contessa, Ring Master and Und Grande outyielded other cultivars. Under the conditions of this study, Contessa, Dorado, Red Creole, Texas Early Grano 502, and Und Grande had the highest yield attributes that made them recommended for growing in the arid regions. The yield and yield attributes of each cultivar will be discussed.

Rice is the world’s largest food crop, and its production needs to be doubled by 2050 to cope with population growth and associated demand. In addition to the value of improving yields, quality is also important for breeders and consumers, but it pays less attention in arid regions. During two successive summer growing seasons, the experimental material focused on 34 genotypes developed from different crosses on Fn generation after fixation as well as six of the most recent commercial cultivars used for comparisons. The results showed that a high yield of grain followed by high milling and grain quality characteristics were observed among the 34 genotypes used in this analysis. Highly important and positive correlations between the percentage of hulling and the percentage of milling (0.424) and the yield ability could be accomplished by choosing the number of panicles per plant and the weight of the panicles. Selection criteria for good quality should be met by the percentage of head rice and many mineral elements, particularly zinc and iron. As a consequence, the genotypes M.J 5460S/SK105-1, M.J 5460S/GZ7768-1, M.J 5460S/G177-1, M.J 5460S/SK105-3 and M.J 5460S/SK106-4 had desirable high yield and quality characteristics and could be used as promising accessions to the rice breeding program in arid regions. In addition to commercial genotypes, improved Japonica rice genotypes could be produced in arid conditions for higher yield and quality, leading to an increase in total production, supporting food security and nutrition.

This research was conducted to investigate the effect of different herbicides with weed management practices on growth and yield performance of mungbean genotypes. The experiment consisted of two factors were mungbean genotypes and weed management. There were two genotypes namely BARI Mung 6 and BARI Mung 8. While there were five weed management practices namely control/no weeding and without herbicide application (T1), hand weeding at 20 and 40 DAS (T2), pre emergence herbicide (Panida) at 1-2 DAS (T3), pre emergence herbicide (Neon) at 2-3 DAS (T4), and post emergence herbicide (Neon) at 10-15 DAS+hand weeding (T5). The results revealed that BARI Mung 6 stand superior to BARI Mung 8 in respect of dry matter content/plant, pods/plant, seeds/plant, seed yield, and 1000 seed weight. Among weed management practices, maximum plant height (53.70 cm), dry matter weight/plant (17.96 g), pods/plant (18.31), seeds/plant (171.47), maximum weed control efficiency (33.78 %) obtained from T3 treatment. Based on the interaction effect showed that BARI Mung 6 weeded with pre emergence herbicide (Panida) at 1-2 DAS produced maximum seed yield (1.79 t/ha) as well as yield attributes showed 2.29 % higher seed yield.

ABSTRACT Knowledge of how climatic conditions affect plant morphophysiology is essential for understanding how to manage the growth cycles of different crops. The aim of this study was to evaluate the effects of the growing seasons in a semi-arid area on the morphophysiological variables of ornamental sunflower plants. The experiment was carried out in a randomized block design in a split-plot arrangement with four replicates. Six cultivars (‘Bonito de Outono Sortido’, ‘Sol Noturno’, ‘Sol Vermelho’, ‘Jardim Amarelo Alto’, ‘Girassol F1 Sunbright Supreme’ and ‘Girassol F1 Vincents Choice’) were evaluated in the main plots and two different growing seasons (GS) in the subplots (GS1 - warm climate and GS2 - mild climate). Evaluations of gas exchange, chlorophyll indices, and leaf surface area were carried out at the reproductive stage (R5.5). The cultivation of ornamental sunflowers in semi-arid regions was significantly affected by the growing season. Changes in gas exchange variables and the morphophysiology of ornamental sunflower plants in the two growing seasons reflected the high phenotypic plasticity characteristic of this species. The cultivation of ornamental sunflowers under semi-arid conditions in the growing season, when air temperature and solar radiation are high, could be limited due to elevated transpiration rates. Therefore, it is recommended that they are grown mainly during the moderate climatic season in semi-arid regions.

Low-fertility soil is considered a major challenge for growing wheat (Triticum aestivum) in organic systems. The objective of this study was to identify spring wheat genotype(s) adapted to growing in organic systems with low-fertility soil compared with conventional systems in the central region of Saudi Arabia. Organic and conventional trials were established during the 2010, 2011 and 2012 growing seasons in the arid environment of central region of Saudi Arabia. Both trails were seeded in a sandy loam soil. Eight bread wheat genotypes were evaluated for the following parameters: grain and straw yields, grain-filling rate (GFR), days to heading (DTH), days to maturity (DTM), number of kernels per spike and 1000-kernel weight. The experiment was a randomized complete block design (RCBD) with four replications. The findings showed that there were significant differences in grain and straw yields between the two systems and among genotypes. The Egyptian genotypes 'Sids 12' and Early-line produced the highest grain yields (7.8 tons ha-1) in the conventional system, whereas in the organic system, Yocora Rojo (control genotype) and Early-line produced the highest yields (5.8 and 5.9 tons ha-1, respectively). Grain and straw yields were higher in 2011 and 2012 growing seasons compared to 2010. Early-line and ICARDA genotypes (IC8 and IC17) had the highest grain-filling rate, whereas the Australian genotypes (P5 and P3) and the local genotype 'Sama' had the lowest grain-filling rate. The genotype Early-line had the shortest time to heading and maturity in both systems. Therefore, Early-line and Yocora Rojo are promising bread wheat genotypes for organic production systems in low-fertility soil.
