Modeling of longitudinal data from agricultural experiments using growth curves helps understand conditions conducive or unconducive to crop growth. Recent advances in Geographical Information Systems (GIS) now allow geocoding of agricultural data that help understand spatial patterns. A particularly common problem is capturing spatial variation in growth patterns over the entire experimental d...

Unsupervised learning algorithms (e.g., self-supervised learning, auto-encoder, contrastive learning) allow deep models to learn effective image representations from large-scale unlabeled data. In medical analysis, even unannotated data can be difficult obtain for individual labs. Fortunately, national-level efforts have been made provide efficient access biomedical previous scientific publicat...

Tillage practices can influence crop root development. Root distributions were determined for wheat (Tdicum aestivum L.) grown in a wheat-fallow rotation during the 1977-1978 winter wheat crop year on an Alliance silt loam (Aridic Argiustoll). The fallow tillage treatments were plow, subtillage, and chemical (no tillage). Each tillage treatment was split into subplots for N application of 0 or ...

The objective was to evaluate the effect of different irrigation systems and harvest frequencies on cultivation cactus pear. study conducted in semi-arid region, municipality Russas, CE, Brazil. experiment a split plot randomized block design, with four replications. Plots were represented by (surface drip, microsprinkler, Micro Spray Jet, conventional sprinkler) subplots (6, 9, 12, 18 months)....

Restricting the randomization of hard-to-change factors in industrial experiments is often performed by employing a split-plot design structure. From an economic perspective, these designs minimize the experimental cost by reducing the number of resets of the hard-tochange factors. In this paper, unbalanced designs are considered for cases where the subplots are relatively expensive and the exp...

1 Although it is well established that nitrogen and light play major roles in structuring plant communities across the landscape, it is not as clear how they structure communities within forest stands. Virtually nothing is known about within-stand structure of understorey communities of herbs and small shrubs in near-boreal forests. 2 We tested the hypothesis that fine-scale (5–20 m) variabilit...

We compared white-tailed deer (Odocoileus virctinianus) use of 15 field corn (Zea mays) hybrids grown in food plots near 3 deer wintering areas in southwestern Minnesota, 1987-88. Physical and morphological characteristics of corn varied significantly among sites, subplots and among hybrids. Deer use of hybrids was significantly different and 5 use groups of hybrids were identified. A significa...

water and soil salinity in some regions of isfahan, east azerbaijan, and west azerbaijan provinces and also other parts of the iran are the main hindrance for crop planting. seeds of the tolerant crops to salinity such as cotton and sugar beet may have optimal germination and give acceptable performance if they become far from salt accumulation areas. to evaluate the effects of different planti...

The objective of this study is to assess the possibility using unmanned aerial vehicle (UAV) multispectral imagery for rapid monitoring, water stress detection and yield prediction under different sowing periods irrigation treatments common bean (Phaseolus vulgaris, L). used a two-factorial split-plot design, divided into subplots. There were three (plots; I—mid April, II—end May/beginning June...
