A field experiment was conducted during the Rabi season of 2020-21 and 2021-22. The laid out in split-split plot design with 27 treatment combination comprising three moisture conservation practices viz. flat bed 2.5 t/ha crop residue, narrow furrow t ha-1 residue broad main seed inoculation control, rhizobium PSB sub zinc level kg Zn 5.0 sub-sub plot. Result shows that produced significantly a...

Several industrial experiments are set up using second-order splitplot designs (SPDs). These experiments have two types of factors: whole-plot (WP) factors and sub-plot (SP) factors. WP factors, also called hard-to-change factors are factors whose levels are hard or expensive to change. SP factors, also called easy-to-change factors are factors whose levels are easy or less expensive to change....

Parametric methods are commonly used despite evidence that model assumptions are often violated. Various statistical procedures have been suggested for analyzing data from multiple-group repeated measures (i.e., split-plot) designs when parametric model assumptions are violated (e.g., Akritas and Arnold (J. Amer. Statist. Assoc. 89 (1994) 336); Brunner and Langer (Biometrical J. 42 (2000) 663))...

i ABSTRACT In mixture-process variable experiments, it is common that the number of runs is greater than in mixture-only or process-variable experiments. These experiments have to estimate the parameters from the mixture components, process variables, and interactions of both variables. In some of these experiments there are variables that are hard to change or cannot be controlled under normal...

Considering general prime or prime powered factorials, we give a nite projective geometric formulation for regular fractional factorial split-plot designs. This provides a uniied framework for such designs and facilitates their systematic study under the criteria of minimum aberration and minimum secondary aberration; the latter criterion is introduced to achieve ner discrimination. We investig...

SUMMARY We propose a general and unified approach to the selection of regular fractional factorial designs which can be applied to experiments that are unblocked, blocked, with random or fixed block effects, or have a split-plot structure. Our criterion is derived as a good surrogate for the model-robustness criterion of information capacity. In the case of random block effects, it takes the ra...

Biochar and manure may be used to enhance soil quality productivity for sustainable agriculture forestry operations. However, the response of surface belowground wood decomposition (i.e., processes) nutrient flux amendments is unknown, more site-specific information about property responses also essential. In a split-plot design, was amended with three rates (whole plot; 0, 3, 9 Mg ha−1) biocha...

Abstract Select varieties with high yields and adaptive to the environment are one way increase corn productivity. The study aimed determine adaptability of growth yield characteristics superior national hybrid maize shade stress. was carried out in a community forest area, Kalices Village, Kendal Regency, from March-September 2020. designed using split-split plot randomized block design treatm...

Effects of the application potassium silicate (PS) and an arbuscular mycorrhiza fungus (AMF) (Glomus mosseae) were investigated on alleviating impacts drought stress Matthiola incana in a split-split-plot experiment two consecutive years. The main plot was assigned to at three levels irrigation (25%, 50%, 70%, field capacity) comparing with control (100% sub-plots AMF (0 200 g fungi pots) sub-s...
