background and objectives: potato (solanum tuberosum l.) plant is one of leading agricultural products in the world. it is the fourth most cultivated food crop after wheat, rice and maize. planting density and weight of minituber are the factors influencing on the yield and yield components on seed tuber production in potato. plant density strongly affected yield, both by number and by weight a...

This study aimed to determine plant performance and added value of soybean farming by applying tillage spacing. was conducted two treatments, namely treatment I: no-tillage scatter planting system on farming, II: spacing farming. Primary data were in the form performance, production, The analyzed descriptively using average growth productivity, RCR, BCR, MBCR. results showed that with resulted ...

Invasive soilborne plant pathogens cause substantial damage to crops and natural populations, but our understanding of how to prevent their epidemics or reduce their damage is limited. A key and experimentally-tested concept in the epidemiology of soilborne plant diseases is that of a threshold spacing between hosts below which epidemics (invasive spread) can occur. We extend this paradigm by e...

A field experiment was conducted at wondo genet Agriculture research center under irrigated condition to determine the effect of intra and inter-row spacing on growth and yield of Artemisia (Artemisia annua L.) during the two successive seasons of 2013 and 2014. Factorial combinations of four intra-rows (40, 60, 80, 100 cm) and four inter-row plant spacing’s (60, 80, 100, 120 cm) were laid out ...
