The main objectives of this expt. were to study the optimum dosage of the preemergence herbicide, oxyfluorfen, on different soil types by evaluating the chemical injury on cassava leaves; investigate the relationship between the diameter of the cutting and the initial growth; analyze aspects of m...

To evaluate the influence of the depth of a compacted layer in the yields of some vegetables, in an Andisol, (Tibaitata, Sabana de Bogota) experimental plots compacted to 5, 10, 15 and 30 cm were used. Each depth resembled the compactation caused by the constant use of rotovator, light harrow, he...

A descriptive and integrated look at the physiology of the bean plant is presented. Initially, the basic physiological processes that determine bean yields are discussed, namely (1) metabolic events such as photosynthesis, respiration, and N metabolism, which have a direct effect on growth, and (...

The effect of 2 daylength treatments (11 and 15 h) on stem elongation was determined in 5 indeterminate bean cv. (G 17650, G 2997, DOR 44, G 5475, and JU 80-11) under growth chamber conditions. Under the short day length, G 17650, a viny indeterminate var. showed the longest stem under all condit...
