“…A PRB system also reduced waterlogging and increased grain yields in monoculture systems of Western Australia (Bakker et al, 2010a, 2010b). Limon‐Ortega and Sayre (2012) confirmed the effects of rainfall on wheat yields in a PRB wheat–maize rotation system in the highlands of Mexico and pointed out that wheat grain yield was mostly determined by the amount and distribution of rainfall during the cropping season. Panettieri et al (2013) investigated the effect of permanent bed planting combined with controlled traffic on soil chemical and biochemical properties under irrigated semiarid Mediterranean conditions with a maize–cotton rotation system.…”

Beijing is located in the northern part of China, with an annual mean temperature of 11.0 to 12.0°C, and growing degree days are limited during the year. Increasing the soil temperature of the seedbed is benefi cial for the winter plants the region of Beijing, where a wheat-maize annual double-cropping system is practiced. Raised beds have the eff ect of restoring the soil temperature. To make use of the advantages of no-till and raised beds, adoption of permanent raised beds is essential (Hari Ram et al., 2011).Combining no-till, permanent bed planting, and furrow irrigation with controlled traffi c, the PRB system has proven itself to be an eff ective method to improve soil properties. Th e developments of PRB technology in diff erent areas are summarized below.In arid and semiarid areas, Verhulst et al. (2011) evaluated the eff ects of tillage and residue management in an arid, irrigated bed planting system with a wheat-maize rotation in an annual double-cropping system and stated that PRB seemed to be the most sustainable option. Devkota et al. (2013) compared permanent beds and residue retention with conventional tillage combined with diff erent levels of residue cover and N fertilization in irrigated arid lands under a cotton (Gossypium hirsutum L.)-wheatmaize rotation system and found that the former can increase water productivity in wheat by 27% and in maize by 84% while increasing yields of wheat by 12% and maize by 42%. A PRB system also signifi cantly increased soil water content, soil temperature, water use effi ciency, soil structure, and spring wheat yield in arid northwestern China under a spring wheat-maize rotation system compared with TT and no-till . In another study, the PRB planting system reduced operational costs up to 40% and enhanced physical and biological soil quality parameters (compared with traditional ridge beds) in the coarse, sandy clay soils ABSTRACT As a typical semi-humid area with a wheat (Triticum aestivum L.)-maize (Zea mays L.) annual double-cropping system, Beijing has the lowest food production per capita and is su ering from severe soil degradation and low seedbed temperature in winter. is study evaluated the permanent raised bed (PRB) system in Beijing from 2005 to 2011 to investigate the e ects of combining no tillage, residue cover, and controlled tra c with raised beds for improving soil properties. We found that the overall soil bulk density (0-30 cm) in PRB plots was signi cantly (P < 0.05) lower (by 12.4%) than that in traditional tillage (TT) plots, while the penetration resistance in the 10-to 20-and 20-to 30-cm soil layers of PRB plots was 18.2 and 26.1% lower (P < 0.05), respectively, than that of TT. e percentage of water-stable soil macroaggregates (>0.25 mm) in the PRB plots was 89.8% (P < 0.05) higher than in the TT plots, while the soil temperature was approximatel...

“…Bed planting also reduced irrigation by 19-24% and hence improved water productivity by 30% [63]. Also, Limon-Ortega and Sayre [52] formulated that the use of bed planting systems has typically been associated with water management topics, which may be related to the borders of percolated water due to smaller areas exposed to the irrigation water and the cultivated area being irrigated in a shorter time. In light of the prediction of an increase in temperatures in the coming years as a result of climate change, the increase of air temperature represents a real risk on wheat production especially under the expected undesired changes in water and planting time and methods, plus the population increase and their demands.…”

Wheat (Triticum aestivum L.) is the uppermost cereal grain crop considered as a major stable food for the Egyptian people. Field experiments were conducted during two consecutive winter seasons of 2017-18 and 2018-19 to study the effect of two planting dates (PD) (20th of November and 20th of December) under four different planting methods (PM) (bed broadcast, flat broadcast, drill at 15 cm, and drill at 25 cm apart rows) on the productivity and water relations of wheat genotype (Egypt 1). The study is intended to assess the water relations for wheat planting dates and planting methods and determine the role of late planting date and planting methods on wheat productivity. Results showed that the values of grain yields and some attributed yields were highly significantly affected by planting dates and methods in the two growing seasons. Planting wheat at the optimal date (20th November) was better than sowing at the late date (20th December) for all values obtained from the studied parameters in both seasons of the study. The bed broadcast planting method gave the highest mean values for all studied parameters except the plant height which was recorded with drilling seeds at a 15 cm planting method in the two growing seasons. The highest values of water applied were recorded with the first date under the borders planting method (PD1M2), while the lowest of Aw recorded was from beds planting method with the second date. The highest mean values for WP were recorded with the bed broadcast planting method.

“…[8] reported that N losses could be minimized if N application is made before the onset of stem elongation. When N was applied at first node stage, the total N uptake was greater than at planting time [9]. Similarly, [10] reported that early application of N at planting and tillering had lower N fertilizer uptake than later application (shooting) in wheat.…”

The performance of wheat cultivars (Triticum aestivum L.) was evaluated using various nitrogen levels and urease inhibitor application stages at New Developmental Farm of The University Agriculture, Peshawar, Pakistan during winter 2012-13. The field experiment was layout in randomized complete block design with split plot arrangement having four replications. Four nitrogen levels (0, 60, 120 and 150 kg ha -1 ) and urease inhibitor stages (100% sowing stage, 50% sowing stage + 50% booting stage and 100% booting stage) were allotted to main plots, while wheat cultivars (Siran and Atta-Habib) were allotted to sub plots. Application of urease inhibitor 100% at sowing stage had maximum nitrogen uptake in root (11.40 g kg -1 ), nitrogen uptake in stem (9.95 g kg -1 ), nitrogen uptake in leaves (15.06 g kg -1 ) and nitrogen uptake in grain (32.68 g kg -1 ) as compared with urease application 100% at booting stage but maximum nitrogen in soil (7.39 g kg -1 ) was recorded when urea coated with urease inhibitor 100% at booting stage. Plots treated with 120 kg N ha -1 produced maximum nitrogen uptake in root (9.90 g kg -1 ), nitrogen uptake in stem (8.94 g kg -1 ), nitrogen uptake in leaves (14.03 g kg -1 ) and nitrogen uptake in grain (29.78 g kg -1 ) as compared with control plots while maximum nitrogen in soil (6.90 g kg -1 ) was recorded when plots treated with 150 kg N ha -1 . Wheat cultivar Siran had significantly produced maximum nitrogen uptake in root (7.04 g kg -1 ), nitrogen uptake in stem (5.86 g kg -1 ), nitrogen uptake in leaves (11.62 g kg -1 ) and nitrogen uptake in grain (25.15 g kg -1 ) as compared to Atta-Habib. It was concluded from this study that cultivar Siran treated with 120 kg N ha -1 and coated urea with urease inhibitor 100% at sowing stage for improved nitrogen uptake in root, stem, leaves and grain and thus, is recommended for general practice in agro-climatic conditions of Peshawar valley.
