PLOT-SIZE IN YIELD SURVEYS

Distance Plot ( B ) Size Plot ( C ) Time

Clustering is an important data exploration task. A prominent clustering algorithm is agglomerative hierarchical clustering. Roughly, in each iteration, it merges the closest pair of clusters. It was rst proposed way back in 1951, and since then there have been numerous mod-iications. Some of its good features are: a natural, simple, and non-parametric grouping of similar objects which is capab...

Estimation of Optimum Field Plot Size and Shape in Paddy Yield Trial

This paper is to estimate the optimum plot size with the shape for field research experiments on paddy yield trial considering the effect of plot size on variability in yield of crop as well as studying the coefficients of variation of different plot sizes and shapes of plots. The maximum curvature technique and comparable variance methods were exercised to estimate optimum plot size and shape ...

Optimising the Selected Neighbourhood for Yield Mapping by Comparing Plot and Monitor Yield Values

This paper deals with yield mapping on the basis of monitor yield data. Every value of the yield map is determined by fitting paraboloid yield surface textures on floating neighbourhoods, but in a robust way so that the influence of outliers is bounded or completely annihilated. The neighbourhood used for fitting the paraboloid cone looks like a huge butterfly flying along the harvest track. In...

The Effects of Plot Shape and Size on Determining the Distribution Pattern of Astragalus verus Olivier

The distribution pattern of plants is an important characteristic of plant communities, being of critical importance in ecological studies and sampling plans. This study was designed to investigate the efficiency of different shapes and sizes of quadrants to delineate the spatial patterns of Astragalus verus Olivier by using dispersion indices. At Mayan Rangeland (Khorasan Razavi), a digital ca...
