A set of studies was conducted to evaluate the effect of two seed . Lemmon, H.E. Whisler, F.D. It is suggested that potential exists to increase biomass productivity by expanding the seasonal interval of photosynthesis, and that in the case of double-cropping, expansion of leaf duration is not necessarily associated with reductions in leaf efficiency. The interaction effect of the two factors brought about significant variation on aboveground biomass, leaf fresh weight, leaf dry weight, and Essential oil yield. Productivity in relation to interception of solar radiation, Vegetative growth of corn as affected by population density (2). Light seems to be the major factor controlling grain yield in this variety of soya bean, low light intensity under the plant leading to a reduction in the number of side branches, number of pods per plant and number of nodes with pods. Over the range of the densities studied grain yield was positively related to number of side branches but negatively related to dry-matter production, leaf area duration and percentage of light intercepted. Until 1948, the USDA recommendation for pickling cucumber spacing was 6 to 7 feet between rows and 3 to 4 feet between plants in the row, for a planting density of 1,500 to 2,500 plants per acre. Therefore, it could be concluded that Artemisia annua could be planted at an optimum spacing of 40 x 60 cm in the Wondo genet area to attain maximum yield. There was a greater positive relationship between total tuber yield and leaf area duration between tuber initiation and the final sampling period than that between it and absolute Leaf area duration. The effect of Abutilon theophrasti on dry matter, branching and flowering node, and seed production of soybean was evaluated and the effect was most pronounced on soybean seed yield, and less on flowering node and dry weight production. 3H55F4/149/1) grown in Tanzania, the total dry matter per plant, pod weight/stem weight, shelling percentage, number of nodes per plant, number of pods per plant. 6.
