Abstract:
... Interseeding cover crops into standing grains can promote both agronomic and environmental benefits within agroecosystems. Producers must decide which cover crops are the best fit for their goals, and whether diverse cover crop mixtures provide benefits that are worth the increased seed cost. Broadcast seeding is an accessible strategy to try interseeding but can lead to patchy establishment; it i ...

Abstract:
... Accurate prediction of flowering is an essential step in understanding the plants’ growth and yield. For this purpose, a field experiment was conducted with 12 sowing dates (across 2012 and 2013) on four cultivars of safflower (Esfahan, Goldasht, Sofeh, and Padideh). Six combinations of functions including three temperature-related and two photoperiod-related functions were compared in a developme ...

Abstract:
... Global warming is expected to affect yield-determining factors of soybean (Glycine max (L.) Merr.), including the number of flowers and pods. However, little is known about the effects of high temperature on the temporal patterns of flowering and pod set. Experiments in the temperature-controlled greenhouses were conducted to examine the temporal pattern of flowering in determinate soybean cultiva ...
... Anthesis stage has been proved a typically sensitive period to heat stress in maize (Zea mays L.), but effects of short–term heat stress around anthesis (tasseling–silking period) are not known. A temperature–controlled experiment was conducted using one heat–sensitive maize hybrid and two temperature levels, 40/30 °C (heat stress) and 32/22 °C (control) in eight different short–term episodes arou ...
... An FNR project entitled “Promotion of Saffron (Crocus sativus L.) cultivation for the profit of arid and semi-arid regions’ women” is led by the CRSTRA. The investigations made during 2013 and 2014 in different arid and semi-arid regions of Algeria have permitted to install Saffron (Crocus sativus L.) cultivation in five principle sites: Ain Zaatout, Beni Souik, Branis, Djemorah and Maafa (Algeria ...
... As practitioners promote passive restoration as a complementary approach to technical reclamation, it is imperative to know its drivers. Although the consequences of endozoochory can be crucial to passive restoration success, few experimental studies assess the use of heavily disturbed sites by seed dispersers such as carnivores and how the seeds they bring in emerge and survive. Using an indoor s ...
... The reduction of yield gap and achievement yield potential of oil plants make a significant contribution to yield increases and oil production in developing countries. This research was carried out to investigate the factors causing yield gap associated with rape seed crop management in the Neka region, east of the Mazandaran province, Iran, through a field study during 2015-2016 and 2016-2017. Bo ...
... Grain growth and leaf senescence are the main processes during post-silking in maize. An unanswered question is how changes in sink strength (the number of grains to be filled) affect leaf senescence. We studied the effect of changes in the source-sink ratio during grain filling on the dynamics of green leaf area and photosynthetic rate. Maize plants were exposed to ear removal, pollination preven ...
... To investigate the effects of agronomic practices and farmer demographics on levels of weed infestation in chickpea fields, a survey was conducted during 2015 in Sanjabi district, Kermanshah, Iran. Two sets of data were collected: (a) weed sampling from the selected chickpea fields, and (b) questionnaire recording of farmer demographics and agronomic management. The farmers were asked about their ...

Abstract:
... Soybean (Glycine max (L.) Merr.) may contribute to the agro-ecological transition of cropping systems in Europe, but its productivity is severely affected by summer drought. New drought-avoidance cropping strategies, such as early sowing, require cultivars with high early plant growth under suboptimal conditions. This study aims at phenotyping early-stage root and shoot traits of 10 cultivars comm ...

Abstract:
... Safflower (Carthamus tinctorius L.), a multipurpose plant grown in many areas of the world primarily for oil extraction from seeds for food and industrial application, recently has been drawn attention as a source of natural colourants. A two-year study was carried out to examine the combined effects of sowing time (24 February, 28 March, 26 April, in 2017; 21 February, 28 March, 24 April, in 2018 ...
... The global mussel aquaculture industry relies heavily on the use of wild seed mussels or spat to initiate aquaculture production. However, production efficiency is often compromised by the poor performance of spat following seeding onto aquaculture substrates such as grow ropes. A potential cause of poor performance of spat is compromised nutritional condition that can be associated with poor natu ...
... Glebionis coronaria (L.) Cass. ex Spach is a troublesome weed in cereal cropping systems in northern Tunisia. Recently, failures in controlling this weed have been reported by farmers. Field surveys and farmers interviews were conducted to highlight the potential causes of G. coronaria occurrence and the associated yield losses in wheat. Survey results revealed a significant correlation between fa ...

Abstract:
... Water is a key driver of agricultural production, the scarcity of which the production is adversely affected; hence, it is critical for the agriculture system and global food security. Water use efficiency (WUE) can be an effective measure to reduce water demand against crop yield as it depends upon water consumption. Thus, the purpose of this research was aimed to estimate the effect of variation ...
... To solve the energy crisis and protect the ecological environment has been the central concern of the sustainable development debate. The reproducibility and lower environmental impacts of bioenergy have attracted increasing attention in the debate. This research investigates the potentials of growing rapeseed in winter fallow fields across the Yangtze River Basin (YRB) to serve the goal of boosti ...
... Little is known about optimising the productivity of intercropping through exploiting differences between genotypes. Our study evaluates the performance of three winter wheat cultivars and eight winter faba bean genotypes (experimental inbred lines) sown as replacement row intercrops with sole cropping comparisons. Detailed agronomic, physiological and soil-based measurements were taken over three ...

Abstract:
... Changes in the environment that are associated with different sowing dates can be expected to alter canola (Brassica napus L.) growth and development. The objective of this work was to study the effect of sowing date and chitosan on some characters of canola genotypes. Five genotypes (RGS003, Sarigol, Zafar, Dalgan, and Julius) were sown in three sowing dates (October 7, 17, and 27), for two years ...

Abstract:
... Garlic is an important economic crop whose planting areas has been annually increasing. Studies have shown that the direction of garlic cloves at the time of sowing has important effects on the germination time, yield and visual appearance of garlic. In order to ensure that the garlic cloves are upright when garlic is planted, an adjustment device based on computer vision has been designed to re-d ...
... Sowing time and cultivar choice have major effects on chickpea yield in the Mediterranean climate, but the effects on nutrient requirements are not well known. Information regarding nutrient requirements and utilization efficiency by crop species is necessary to optimize nutrient management in agricultural systems.
