Results of 2 on-farm trials carried out in Peru during 1986 are presented in table form. In 1 of the trials, drought-tolerant bean var. were evaluated with 1 and 2 irrigation treatments. In the other trial, potentially rust- tolerant var. were evaluated at 2 plant densities. For drought condition...

Se presentan los resultados en forma de tabla de 2 ensayos realizados en Peru durante 1986. En un ensayo se evaluaron var. de frijol tolerantes a la sequia con 1 y 2 riegos. En el otro se evaluaron var. potencialmente tolerantes a roya a 2 densidades de siembra. Para sequia las var. promisorias f...

Sowing density is a major management factor that affects growth and development of grain crops by modifying the canopy light environment and interplant competition for water and nutrients. While the effects of sowing density and plant architecture on static vegetative and reproductive growth trai...

Arachis pintoi is a valuable forage legume for tropical savannas, persisting with vigorous tropical grasses under widely differing management systems. However, seed is expensive, so that vegetative planting is an option, particularly for small farmers. We studied the growth and development of A. ...

The effect of cycle on root system and shoot development was studied for two crop cycles (plant crop and first ratoon). The study revealed that shoot and root system development declined from the plant crop to the first ratoon for plants grown on degraded Ultisols in south-eastern Nigeria.

El efecto cíclico en el sistema radical y en el desarrollo de otras partes de la planta fue estudiado durante dos ciclos de producción (siembra y primer renuevo). El estudio reveló que el desarrollo del sistema radical y otras partes de la planta declinó desde el momento de la siembra hasta el pr...
