Rice landraces of Nepal: A reflection of past

Background This is really a brash article meant to convey exactly what title hints at. Much of the contents are translated/transliterated from “Rice Science and Technology in Nepal: A historical, socio-cultural and technical compendium”, which was published in 2017.

Design and analysis of spit plot experiments

Split plot design Design and fieldbook template In a field experiment to test for effects of fungicide on crop, treatment of fungicides may be distinguised into multiple factors – based on chemical constituent, based on formulation, based on the mode of spray, etc.

Layout and visualization of experimental design

Functional approach to creating and combing multiple plots This approach highlights features of gridExtra package that allows combining multiple grob plots using function calls. We explicitly use lapply/split or similar class of purrr functions to really scale the graphics.

Design and analysis of balanced randomized complete block (RCBD) experiment

Introduction Balanced block designs are a class of randomized experimental design that contain equal number of records for a particular level of categorical variable across all blocks. Example 1 Let us generate some data from random process mimicking a single factor process consisting of 3 levels.

Varietal database of lentil in Nepal

This one is my effort to compose an updated database on the current situation of lentil germplasm in Nepal. I’ve managed to list out the varieties that have been made available so far (either through release or registration process).

Flowering phenology of Rice genotypes in irrigated tropical condition of Nepal

Dhangadhi of Kailali, Nepal remains relatively hotter during summer season with respect to average condition of terai agro-ecology. A regime of high day temperature with bright sunshine and cool night temperature along with plenty of seasonal rain during larger part of rice growing season favors good growth of rice crop in the region.
