Association Of Digital Photo Parameters And Ndvi With Winter Wheat Grain Yield In Variable Environments, Alexey Morgounov, Nurberdi Gummadov, Savaş Belen, Yüksel Kaya, Mesut Keser, Jamala Mursalova

The normalized difference vegetation index (NDVI) is gaining popularity as a complementary selection tool, even though it requires an instrument not readily available in the developing world. We evaluated several parameters (originating from the analysis of digital photos using BreedPix software) as potential selection criteria in 23 winter wheat yield trials grown over 4 years at 2 sites. NDVI and digital photos were taken at key development stages from stem elongation to maturity. The correlations between digital photo parameters a and u and grain yield, as well as correlations between NDVI and grain yield within individual trials, varied depending on …
Siberian Elm Responses To Different Culture Conditions Under Short Rotation Forestry In Mediterranean Areas, Ignacio Pérez, Javier Pérez, Juan Carrasco, Pilar Ciria
Siberian Elm Responses To Different Culture Conditions Under Short Rotation Forestry In Mediterranean Areas, Ignacio Pérez, Javier Pérez, Juan Carrasco, Pilar Ciria
Turkish Journal of Agriculture and Forestry
This work explores the possibilities of biomass production, for energy purposes, of Siberian elm in Mediterranean areas, including marginal lands with poor soil and low water availability. To achieve this, the influence of soil type, planting density, and water availability on biomass production were analyzed after the first 3 years of the growing cycle in 2 different locations. Moreover, a method to estimate biomass production as a function of some morphological parameters of the trees, as well as the use of leaf water potential as a good indicator of trees' water status, are discussed. The analysis of parameters having an …
Growth, Biomass, Carbon Stocks, And Sequestration In An Age Series Of Populus Deltoides Plantations In Tarai Region Of Central Himalaya, Gurveen Arora, Sumit Chaturvedi, Rajesh Kaushal, Ajeet Nain, Salil Tewari, Nurnabi Meherul Alam, Om Prakash Chaturvedi
Growth, Biomass, Carbon Stocks, And Sequestration In An Age Series Of Populus Deltoides Plantations In Tarai Region Of Central Himalaya, Gurveen Arora, Sumit Chaturvedi, Rajesh Kaushal, Ajeet Nain, Salil Tewari, Nurnabi Meherul Alam, Om Prakash Chaturvedi
Turkish Journal of Agriculture and Forestry
Growth, biomass, carbon storage, and carbon sequestration potential along an age series in Populus deltoides plantations were assessed. The growth rate of diameter at breast height and height was higher in trees of 4 to 7 years and 2 to 5 years, respectively. The total aboveground biomass (AGB) increased with age and reached its maximum (180.2 Mg ha^{-1}) at 11 years of age. Mean carbon concentration in aboveground components varied from 39.7% to 51.7%. Allometric equations were developed to estimate biomass and biomass carbon in different tree components, which had adjusted R squares greater than 94%. Aboveground carbon stocks in …

The objective of this study was to investigate the responses of peanut genotypes to midseason drought, regarding in particular nutrient uptakes and their correlations with biomass production and pod yield. The experiment was conducted during the dry seasons of 2011/12 and 2012/13. Five peanut genotypes with different levels of drought tolerance and 2 water regimes (well-watered and midseason drought) were laid out in a split-plot design with 4 replications. Midseason drought was imitated by stopping irrigation at 30 days after planting (DAP) and then rewatering at 60 DAP. The data were recorded for contents of N, P, K, Ca, and …
