For hierarchical clustering, dendrograms provide convenient and powerful visualization. Although many visualization methods have been suggested for partitional clustering, their usefulness deteriorates quickly with increasing dimensionality of the data and/or they fail to represent structure between and within clusters simultaneously. In this paper we extend (dissimilarity) matrix shading with ...

The role of grass tussocks in supporting soil microbial biomass (SMB) in grazed ecosystems is not fully understood, nor is the spatial distribution of SMB in response to different grass species. We undertook a study in 1997 that examined ®ne-scale distributions of SMB in grazed experimental paddocks located in the eucalypt woodlands of northern Queensland, Australia. Levels of SMB were determin...

the performance of different yield loss models from an exponential family was evaluated in safflower-redroot pigweed systems in two field experiments conducted during 2007 and 2008 growing seasons at the research field of agricultural college of shiraz university, iran. the yield loss of safflower was recorded as relative yield loss in experimental plots laid out in split plot design with three...

to study the effect of sowing date and a single irrigation (si) on yield and yield components of barley, a field experiment was conducted in dryland agricultural research institute (maragheh, iran) in 2004-06 cropping seasons, using a split plot based on a randomized complete block design with 3 replications. main plots were assigned to 3 levels of sowing date (early, normal and late). sub-plot...

Longitudinal repeated-measures data have often been visualized with spaghetti plots for continuous outcomes. For large datasets, the use of spaghetti plots often leads to the over-plotting and consequential obscuring of trends in the data. This obscuring of trends is primarily due to overlapping of trajectories. Here, we suggest a framework called lasagna plotting that constrains the subject-sp...

Intensive tillage with no crop residue after rice harvest in conventional wheat cultivation increases the turn around time, delays sowing and affects yield. A field experiment was carried out to assess effect of dates, establishment methods mulching their interaction on growth, productivity profitability spring at agronomy farm AFU, Rampur Chitwan, Nepal from November 2020 April 2021. The laid ...
