Implications of Experimental Design on Predicting Economic Optimum Nitrogen Rates in Rice

Agronomy, 2021
Nitrogen (N) response studies in rice (Oryza sativa L.) are conducted to provide grower recommendations with economically optimum N rates (EONRs). This study was conducted to determine if experimental design alters the predicted EONR for rice.

Order Restricted Randomized Block Designs

Journal of Agricultural, Biological and Environmental Statistics, 2023
AbstractField experiments are run under two competing objectives, high precision and minimal cost. The precision can be increased either by using sound experimentation techniques that account for the sources of variation with reasonable statistical models or by increasing the sample size.

Impact of Production Inputs and Timing on Crackness of Rice in Northern Ghana

International Journal of Agronomy, 2021
Under rain-fed conditions, perfumed rice production in Northern Ghana is associated with high paddy cracking during milling. In this study, 4 perfumed rice varieties, 6 staggered planting times, 6 staggered harvesting cycles, and staggered storage ...
