“…One of the reasons for low yield is waterlogging (30 days the water table depth was less than 30 cm, as shown in Table 13) or shallow mean of water table (Table 12). In evaluations, a high reduction (14%-23%) in canola yield (rapeseed) was observed with a prolonged period of waterlogging, especially during winter [46,47]. In the second and fourth seasons, the canola under the Bi-level and D 0.90 L 30 treatments had the highest grain yield, respectively.…”

Subsurface drainage is a prerequisite to grow winter crops in the consolidated paddy fields in Northern Iran. A four-year study (2011)(2012)(2013)(2014)(2015) was conducted to quantify the effects of subsurface drainage on the saturated hydraulic conductivity, water table, drain discharge and winter crop yields. Subsurface drainage systems with two drain depths of 0.65 and 0.90 m and two drain spacings of 15 and 30 m were installed at the consolidated paddy fields of Sari Agricultural Sciences and Natural Resources University, Iran. During four successive winter seasons, the water table depth and drain discharge were measured daily. Soil saturated hydraulic conductivity was measured twice; before drainage system installation and four years following the installation. Canola grain yields were determined at harvest of each cultivation season. During the study period, the soil saturated hydraulic conductivity increased with the highest increase in the top 0-30 cm. The deeper drains were more effective in controlling the water table compared to the shallow, and the daily drain discharge of the deeper drains in the fourth year were higher than those of shallow drains. The canola grain yield of all drainage systems increased significantly by the seasons, and the largest difference in canola grain yield between first and fourth seasons was 2191 kg¨ha´1 (318% increase) in the fields with 0.90 m drain depth and 30 m drain spacing. Totally, it became clear that installation of subsurface drainage systems with 0.90 m depth and 30 m spacing in the paddy fields of Northern Iran can be recommended to achieve high yield of winter crop, soil condition improvement, and multi-purpose land use.

“…This could be a major reason that the podding stage maps showed a different trend than the crop growth. As for the response of crops to waterlogging, most of the previous studies put more emphasis on the impacts of waterlogging on photosynthesis and the transpiration rate, plant hormones, antioxidant enzymes, and other physiological and biochemical indices [11,13,47], and the influence of waterlogging stress on plant morphological indices, such as plant height, green leaf number, effective pod number, yield per plant, and 1000-grain weight [3,4,8,10,12]; few studies have been done on the vegetation growth and health information, such as LAI and AGB under waterlogging conditions [69,[72][73]. In this study, we find that waterlogging stress can reduce the oilseed rape biomass, which has a similar consequence with previous studies [3,4,74].…”

“…Few studies have been conducted on different growth stages of field-grown oilseed rape under varying soil moisture [4,10,11]. Detailed field experiments have been predominantly directed toward analyzing the impacts of soil water content variability on physiological parameters and fruit yield [8,12,13]. Indeed, water productivity relates crop production to water use and is a key indicator for evaluating agricultural water management [9].…”

Abstract:Oilseed rape (Brassica napus L.) is one of the three most important oil crops in China, and is regarded as a drought-tolerant oilseed crop. However, it is commonly sensitive to waterlogging, which usually refers to an adverse environment that limits crop development. Moreover, crop growth and soil irrigation can be monitored at a regional level using remote sensing data. High spatial resolution optical satellite sensors are very useful to capture and resist unfavorable field conditions at the sub-field scale. In this study, four different optical sensors, i.e., Pleiades-1A, Worldview-2, Worldview-3, and SPOT-6, were used to estimate the dry above-ground biomass (AGB) of oilseed rape and track the seasonal growth dynamics. In addition, three different soil water content field experiments were carried out at different oilseed rape growth stages from November 2014 to May 2015 in Northern Zhejiang province, China. As a significant indicator of crop productivity, AGB was measured during the seasonal growth stages of the oilseed rape at the experimental plots. Several representative vegetation indices (VIs) obtained from multiple satellite sensors were compared with the simultaneously-collected oilseed rape AGB. Results showed that the estimation model using the normalized difference vegetation index (NDVI) with a power regression model performed best through the seasonal growth dynamics, with the highest coefficient of determination (R 2 = 0.77), the smallest root mean square error (RMSE = 104.64 g/m 2 ), and the relative RMSE (rRMSE = 21%). It is concluded that the use of selected VIs and high spatial multiple satellite data can significantly estimate AGB during the winter oilseed rape growth stages, and can be applied to map the variability of winter oilseed rape at the sub-field level under different waterlogging conditions, which is very promising in the application of agricultural irrigation and precision agriculture.

“…The oil content of rape is an important quantitative trait influenced by environmental conditions (Jensen et al, 1996;Gutierrez Boem et al, 1996) but phenotypic variation in oil content is also mainly controlled by the genotype and genetic and environmental (GE) interaction effects.…”

Analysis of genetic main effects and genotype x environment (GE) interaction effects on the oil content of oilseed rape (Brassica napus L.) was conducted by using a genetic model for the quantitative traits of seeds in diploid plants. The experiments were carried out over two years with 8 parents and a diallel mating design, which produced F 1 and F 2 generations. We found that the oil content of rape was simultaneously controlled by embryo genetic effect, cytoplasmic effects and maternal genetic effect as well as GE interaction effects, with the cytoplasmic and maternal effects playing the main role. The results indicate that selection of maternal plants for high oil content would be more efficient than selection based on single seeds. Since the GE interaction effects accounted for 73.69% of the total genetic effects and were more important than the genetic main effects it seems that selection might be influenced by environmental conditions. The estimate of narrow-sense heritability for oil content was 73.52% with the interaction heritability being larger than the general heritability, indicating that the early generations can be used for selection for high oil content. The prediction of genetic effects suggested that the parent cultivars Youcai 601 and Gaoyou 605 were better than the other cultivars for increasing oil content during the breeding of B. napus. The implications for the quantitative trait loci mapping of seed traits interfered by these three genetic systems is also discussed.
