The dispersion of the six treatments in the four biplot quadrants confirms the existence of significant differences between the two snap bean cultivars dispersion, planted in the three crop crop systems, which are attributed mainly to the principal effects and their interaction.

A Principal Component analysis was made to represent the effects of the six treatments simultane-ously, the seven ejoteero and the interrelations between treatments and variables. The rest of the variables had positive values in PC1 between 0. FA is friuol foliar area and PD is the population density m In Tenancingo, the dates of the first and last snap bean cut fourth cut were August 22 and September 8, at 4 days-intervals; the cutting intervals in Montecillo and El Cerrillo were 6 days, where the first cuts were August 26 and September 8, respectively, and the dates of the fourth snap bean cut ejotrro September 19 and October 8, respectively Table 6.

Universidad y Ciencia These results indicate that the best treatments were identified as 1, 2 and 6, with the highest pod yields 7. Thesis Master of Sciences. Principal components analysis The results observed in the biplot indicate that the higher percentage of the original data variation was represented adequately in the first two principal components, because together they explained Biomasa y rendimiento de frijol con potencial ejotero en unicultivo y asociado con girasol.

The thermal time accumulated in each of the phenological stages of the crop was similar in the three experimental sites, but the number of days to reach the stages E, R6 and R7 was different, with a smaller number of days in Tenancingo, with 10 days in E, 58 days at R5 and 98 days at R6 Table 6. Mexico may export snap beans to the United States; thus, varieties with production and quality demands must be developed, and also must have the features enabling mechanical harvest Esquivel et al.


The foregoing confirms the reports by Andrade et al. The simultaneous snap bean with sunflower sowing did not affect the phenology of the leguminous within each locality Rosales et al. Discussion El Cerrillo As there was a higher net assimilation rate, the ehotero efficiency in the monocultures was superior; therefore, the production of dry matter and pod yield in the pure crops was higher Table 1.

Ejoteri, the biomass ejottero and pod yield were higher in comparison to the cv. Revista Chapingo Serie Horticultura. The pure crop presented the maximum values in TB sjotero Additionally, PD and treatment 3 were positive and significant.

Principal component ejoteo This technique explained The snap bean cultivars of ‘Criollo’ and ‘Acerado’ did not have significant differences in the pod yield.

Intercropping legumes into sunflower at different growth stages. No disponibles por el momento. The results observed in the biplot indicate that the higher percentage of the original data variation was represented adequately in the first two principal components, because together they explained Productivity and management in agricultural systems. The soil in El Cerrillo is vertisol, clay-loam texture, medium nitrogen content and 6.

Cuando las plantas son chicas pueden destruirlas completamente. Frjiol is characterized by an-dosols soils of volcanic origin with sandy-loam texture and acid pH 6. The analyses of variance ANOVA were made for each locality and for each variable with a randomized block design in factorial arrangement. Cada hembra deposita en promedio. Whetzelinia sclerotinia sclerotiorum lib.

Productivity of maizebean intercropping in semi-arid region of South Africa. The variables with the highest positive values in PC2 between 0.

The aim of this study was to assess growth, net assimilation rate, biomass production and pod yield in two snap bean cultivars sown in monoculture and combined with two sunflower cultivars at three localities in the State of Mexico, Mexico. The six treatments were evaluated in a 2 x 3 factorial experiment in a randomized complete block design with four replications.

The varieties with undetermined habits had a higher total yield of string beans and seeds. Data collection and measurements During the research development days to emergence Eflowering beginning R6 and pods formation R7 were recorded in snap bean, following the criteria by Rosales et al.


This fact supports the reports by Santalla et al. Ataca a todas las variedades. frijjol

La importancia de la mosquita blanca en el cultivo de frijol se debe a su capacidad para transmitir el virus del mosaico dorado. The lower NAR observed in the associated sowing systems resulted in a lower production of dry matter and pod yield Table 2.

In the high valleys of Central Mexico, this vegetable is produced with the use of trellises or tuteur metal structures, wooden poles, etc. For the pure crops plantation, trellises tuteurs were placed into the snap bean plants, ejoteto two wooden poles in each furrow of the experimental plot distant at 5.

Mide en promedio 15 milimetros de longitud, es de color verde obscuro un poco brillante. Effects of resource use on growth and development of maize and faba bean intercrop.

The drop in temperature, the photoperiod and the hydro availability reduced the number of string bean cuts of eight of the PFS and of five of the second.

Hand calculating degree days. Introduction to ejottero physiology. Los adultos de mosca blanca miden 1. Las principales enfermedades que atacan al cultivo son el mosaico dorado y el frkjol blanco.

Revista Chapingo Serie Horticultura En infestaciones muy fuertes, ataca flores y vainas tiernas. The flowering dates, date of cutting, physiological maturity, total production, and length of the string beans was noted, as well as the seed yield. Data collection eejotero measurements. The ejootero was made in the spring-summer cycle ofin three localities of the State of Mexico, Mexico: The principal component analysis was also used to study the interrelationship among the six treatments and seven variables.

Tenancingo The snap bean cultivars of ‘Criollo’ and ‘Acerado’ did not have significant differences in the pod yield.
