Probably because you had too much hot, dry wind at the blooming. This is one of the most frequent troubles with beans in the hot valley, but the pink bean resists it better than other varieties. As the heat moderates you are likely to get blossoms which will come through and form pods, and then the crop will depend upon how long frost is postponed. You have also treated the plants a little too well with water and cultivation. You had better let them feel the pinch of poverty a little now; they will be more likely to go to work.
Blackeye Beans.
What is the best way to prepare land for Black-eye beans? How much seed is required per acre, and what is the estimated cost of growing them? The soil is a well-drained clay loam.
The cost of growing is not particularly different from other beans, and will vary, of course, according to the capacity and efficiency of the plows, harrows, teams, tractors, men, etc. Every man has to figure that according to his conditions and methods of turning and fining the land. Sow 40 pounds per acre in drills 3 feet apart, and cultivate as long as you can without injuring the vines too much. Sowing must of course be done late, after the ground is warm and danger of frost is past, though the plowing and harrowing should be done earlier than that.
Blackeye Beans are Cow Peas.
I sent for some Blackeye cow peas; they look like Blackeye beans. Am sending you a sample of what I got. What are they?
Yes, they are in the cow pea group, but there are other cow peas which would not be recognized as having any relation to them. All cow peas are, however, beans, and they have not much use for frost. They are not hardy like the true pea group.
Growing Horse Beans.
Does the soil need to be inoculated for horse beans? I intend to plant five acres about January 1, on the valley border in Placer county and they get heavy frost in the morning. Does frost hurt them? How shall I plant them?
California experience is that horse beans grow readily without inoculation of the seed. Quite a good growth of the plant is being secured in many parts of the State, particularly in the coast region where the plant seems to thrive best. It is one of the hardiest of the bean family and will endure light frost. How hardy it will prove in your place could be told only by a local experiment. Whether it can be planted after frost danger is over, as corn is, and make satisfactory growth and product in the dry heat of the interior summer must also be determined by experience.
