Within the final 3 many years, the worldwide creation of lentils has nearly tripled because of better harvest parts but in addition extra importantly from development in examine and productiveness. Chapters define advancements in construction, corresponding to water and soil nutrient administration, agronomy, mechanization and weed administration.

The quantity of energy consumed per acre or per animal unit for each of the 18 products is shown as a total and also is divided into the three categories of energy utilization. The percen tage of the total for each category is also indicated. In an effort to emphasize differences and similarities in energy utilization the energy requirements were calculated on the basis of kcal per pound of production and also kcal per dollar value of production (1975 product prices). Tables 3 and 4 indicate these results.
Heady would change very little under an energy crisis of the magni tude analyzed. Most of the changes in overall nitrogen use under the energy crisis result in reducing inorganic nitrogen use and increasing utilization of manure and nitrogen from legume crops (Fig. 3).

Changes in nitrogen use as a function of energy shortage. 70 Commercial nitrogen use 5 10 15 Energy Reduction,% (Model A = 0 ) The average nitrogen application (lb/A) under all the energy situations is reduced below the base solution (Table 6).
