Response of Snap beans to Increasing Plant Density

Insecticide Seed Treatments for Snap Beans

The most damaging insect pests are those that attack the pods and result in either damage or contamination of the processed product. The European corn borer (ECB) and to a lesser extent the corn earworm (CEW) are the major pod feeding pests with damage primarily from 2 generation ECB and late flights of CEW in August/September. Damage from both species occurs from flowering to harvest, creating...

Yield and Yield adjustments of nonprolific maize hybrids in response to plant population density

Stomatal Diffusion Resistance of Snap Beans. II. Effect of Light.

The effect of light on the stomatal resistance of abaxial and adaxial leaf surfaces of snap beans (Phaseolus vulgaris L.) was studied in the growth chamber and in the field. The adaxial stomata required more light to open than the abaxial stomata; the abaxial stomatal apertures were still about 50% open at 1% full sunlight and light-induced closure was never observed under daytime field conditi...

Effect of plant density and different irrigation strategieson crop yield and canopy cover of red beans, Phaseolusvulgaris L. cv. Akhtar

ABSTRACT- In order to study the effects of different irrigation regimes and plant density on yield and yield components of bean, a split plot arrangement was conducted in complete randomized block design during two years. The foremost variable was four levels of irrigation: 60, 80, 100, and 120% of the potential evapotranspiration. The second variable was within the row spacing of 5 cm (D1), 10...

Stomatal diffusion resistance of snap beans. I. Influence of leaf-water potential.

Concurrent measurements of abaxial and adaxial stomatal resistance and leaf-water potentials of snap beans (Phaseolus vulgaris L.) in the field and growth chamber show that the stomata on the 2 surfaces of the leaflet react differently to water deficit. The stomata on the abaxial surface, which are about 7 times more numerous than on the adaxial surface, are not significantly affected at leaf-w...
