Sensor-Cloud based Precision Agriculture Approach for Intelligent Water Management Int. J. Plant Prod. (IF 1.169) Pub Date : 2019-11-09 M. Jayalakshmi; V. Gomathi
Water deficits reduce plant growth. Moisture stress affects the development of plant organs, which in turn can have very profound effects on plant growth. Initiation and differentiation of vegetative and reproductive organs, as well as cell division and cell enlargement, are very sensitive to water stress. The size of the vegetative organs in part determines the yield of grain crops, and therefore

Crop and Soil Response to Organic Management Under Mediterranean Conditions Int. J. Plant Prod. (IF 1.169) Pub Date : 2019-11-07 Rita Leogrande; Carolina Vitti; Alessandro Vittorio Vonella; Domenico Ventrella
Organic agriculture can contribute to maintain the long-term sustainability of the agroecosystems, preserve and improve soil quality and guarantee good quality food products. The objective of this study was to investigate the effects of different organic fertilizers and a biostimulant on crop performance and soil properties. The research was performed in an experimental farm in Southern Italy and covered

Effectiveness of physiological traits in adopting safflower ( Carthamus tinctorius L.) genotypes to water deficit condition Int. J. Plant Prod. (IF 1.169) Pub Date : 2019-11-04 Khadijeh Alizadeh Yeloojeh; Ghodratollah Saeidi; Parviz Ehsanzadeh
Water deficit is the most limiting factor for seed yield of crop species in the arid and semi-arid regions. Due to increasing limitation of fresh water resources and importance of safflower (Carthamus tinctorius L.) as a significant oilseed crop in Iran, it is necessary to evaluate physiological responses of drought tolerance and its association with seed yield of this crop in water stress condition

Optimized Planting Density Maintains High Wheat Yield Under Limiting Irrigation in North China Plain Int. J. Plant Prod. (IF 1.169) Pub Date : 2019-11-01 Dongxiao Li; Di Zhang; Hongguang Wang; Haoran Li; Qin Fang; Hongye Li; Ruiqi Li
Regulating plant density is an important practice to improve winter wheat productivity under limited irrigation in North China Plain. Field experiments were carried out over two seasons (2014–15 and 2015–16) under three plant densities (Dh: 480–570, Dm: 360–390, Dl: 240–270 104 plants hm−2) and three irrigation levels (W0: no irrigation; W1: irrigated 80.0 mm only at the jointing stage, which also

Intercomparison and Performance of Maize Crop Models and Their Ensemble for Yield Simulations in Brazil Int. J. Plant Prod. (IF 1.169) Pub Date : 2019-10-31 Yury C. N. Duarte; Paulo C. Sentelhas
Maize yield prediction is of extreme importance for both identifying those locations with high potential for this crop and determining the yield gaps of the crop where it is currently produced. The most feasible way to estimate crop yields is with the use of crop simulation models, since well calibrated and evaluated. Even though, these estimations have uncertainties once the crop models are not complete

Modeling Canopy Carbon and Water Fluxes Using a Multilayered Model over a Temperate Meadow in Inner Mongolia Int. J. Plant Prod. (IF 1.169) Pub Date : 2019-10-28 Nina Chen; Anzhi Wang; Juan An; Yushu Zhang; Ruipeng Ji; Qingyu Jia; Ziqi Zhao; Dexin Guan
To incorporate canopy vertical structure in a process-based model over a temperate meadow, a multilayered model estimated canopy carbon flux (Fc) and water flux (LE) was applied by comparing with eddy covariance measurements in Inner Mongolia, China. Simulations of diurnal, seasonal CO2 and H2O fluxes and model sensitivity to parameters and variables were analyzed. The results showed that the model

Nutritive Value and Enteric Methane Production of Brachiaria spp. Under Elevated [CO 2 ] Int. J. Plant Prod. (IF 1.169) Pub Date : 2019-10-24 A. L. Abdalla; A. L. Abdalla Filho; A. S. Natel; H. Louvandini; M. C. Piccolo; K. L. Nechet; A. Torre Neto; R. Ghini
Despite tropical grasses being the main feed source for major part of ruminant livestock, information about nutritional quality changes under climate changes scenario are still scarce. The novelty of this work was to determine the effects of season and elevated CO2 under field conditions upon biomass production and nutritional value of Brachiaria decumbens during 2 years. The Free-Air Carbon Dioxide

Differential Responses of Seed Yield and Yield Components to Nutrient Deficiency Between Direct Sown and Transplanted Winter Oilseed Rape Int. J. Plant Prod. (IF 1.169) Pub Date : 2019-09-16 Rihuan Cong; Yin Wang; Xiaokun Li; Tao Ren; Jianwei Lu
Both transplanting and direct-sowing are the dominated methods for establishing winter oilseed rape in China. It is important to understand crop performances and responses to nutrient deficiency between transplanted oilseed rape (TOR) and direct sown oilseed rape (DOR). We estimated the effects of establishment methods (transplanting and direct-sowing) and nutrient deficiency (N, P, and K) on rapeseed

Evaluation of Both SPAD Reading and SPAD Index on Estimating the Plant Nitrogen Status of Winter Wheat Int. J. Plant Prod. (IF 1.169) Pub Date : 2019-09-09 Xianlu Yue; Yuncai Hu; Huaizhi Zhang; Urs Schmidhalter
Rapid non-destructive estimation of the plant nitrogen (N) status is needed for the precise management of N in small-scale farms. Our objectives were to describe the responses of the soil–plant analyses development (SPAD) measurements to the plant N status of winter wheat, and to evaluate whether the SPAD index is more precise than SPAD readings in estimating the plant N status. During 2009–2011, a

The Impacts of Interplant Variation on Aboveground Biomass, Grain Yield, and Harvest Index in Maize Int. J. Plant Prod. (IF 1.169) Pub Date : 2019-08-21 Ioannis S. Tokatlidis; Emmanouel Remountakis
Stability of maize (Zea mays L.) hybrids has been major research topics. So far, more emphasis has been placed on the per area grain yield variation, rather than on the plant-to-plant variability within the crop stand, i.e. intra-crop variation. The acquired intra-crop variation of different hybrids was recorded across five environments via the coefficient of variation (CV) of plant-to-plant variability
