Fig. 31 covered with nodules, thus insuring added nitrogen to the soil. In Fig. 30 is shown a Southern California grove with a luxuriant §22 CITRUS J^KUITS UNDER IRRIGATION 35 cover crop of common vetch. Note the excellent stand of the plants and how completely the ground is covered by the crop To secure the best results in Southern CaHfomia, vetch seed should be planted the latter part of August or the first part of September. When planted eariy in the season, vetch makes a good growth before cold weather and continues growing dur- ing the winter. Plantings in October are sometimes made but, as a rule, they are not satisfactory on account of the small growth made before cold weather. In the northern sections common vetch may be sown about October 1. This late plant- ing IS possible on account of the heavy winter rainfalls that occur m this section, which does not permit the turning under of the crop as early as in the southern section. The rate of seeding varies from 40 to 60 pounds per acre In a grove where the trees are 12 years old or older, from 40 to 50 pounds of seed is required per acre. For younger trees, from 50 to 60 pounds per acre is sown. The seed of common vetch usually vanes in cost from 3^ to 5 cents per pound. At the rate of 60 pounds to the acre, the cost for seed is, therefore, from $ to $3 per acre. When bariey is seeded with vetch, the average rate of seeding is 30 pounds of vetch and 30 pounds of bariey. A planting of bariey and vetch is illustrated in Fig. 31. Note the large quantity of foliage. 37. The Canada field pea was the first crop to be used extensively for winter cropping in citrus groves of the West and
