Planting density and selection method in rice plant

open access: yesJapanese Journal of Breeding, 1963
1. An investigation was made on the interaction between genotype and planting density in rice -plant, with the aim of contributing to the breeding of varieties adapted to high planting density. 2. The experiment consisted of two different forms of culture, i. e., early season culture and ordinary season culture.

Modelling diverse root density dynamics and deep nitrogen uptake — a simple approach [PDF]

open access: yes, 2009
We present a 2-D model for simulation of root density and plant nitrogen (N) uptake for crops grown in agricultural systems, based on a modification of the root density equation originally proposed by Gerwitz and Page in J Appl Ecol 11:773–781, (1974). A

Reducing Irrigation and Increasing Plant Density Enhance Both Light Interception and Light Use Efficiency in Cotton under Film Drip Irrigation

open access: yesAgronomy, 2023
High-density planting is an effective technique to optimize yields of mulched cotton. On the other hand, deficit irrigation is an emerging water-saving strategy in cotton cultivation, especially suitable for arid and water-scarce areas.

Pathogenicity of the root-knot nematode Meloidogyne javanica on potato [PDF]

open access: yes, 2005
Host–parasite relationships and pathogenicity of Meloidogyne javanica on potatoes (newly recorded from Malta) were studied under glasshouse and natural conditions. Potato cvs Cara and Spunta showed a typical susceptible reaction to M. javanica under

Different soybean plant arrangements affect ground beetle assemblages

open access: yesJournal of Plant Protection Research, 2019
It was expected that there would be a relationship between plant density and arrangement within soybean plantations and ground beetles due to changes of abiotic habitat conditions.

Estimation of Wheat Plant Density at Early Stages Using High Resolution Imagery

open access: yesFrontiers in Plant Science, 2017
Crop density is a key agronomical trait used to manage wheat crops and estimate yield. Visual counting of plants in the field is currently the most common method used. However, it is tedious and time consuming.

Influence of Seeding Rates on Seed yield, Oil Content, Oil Yield and other Yield Attributes of four Linseed (Linum usitatissimum L), Varieties in Horo Guduru District, Western Ethiopia

open access: yesCogent Food & Agriculture, 2022
Seed rate is one of the agronomic factors that decreases seed yield by subjecting plants to lodging and competition. The field experiment was conducted in 2019/20, and 2020/2GC main cropping seasons on Harato and Gitilo sites to determine the effect of ...
