The Response of Improved Lentils to P Application on Vertisols: the Performance of Lentils and Their Responce to P

When considering profitable agriculture from a practical perspective, the factors affecting plant growth and harvestable productivity are the utmost important. A number of factors, such as genetics, environment and irrigation management, affect yields independently and through their interactions. Knowledge of these factors, the interactions, and how to manipulate them make it possible for the farm operation to maximize the return. Of course, all are not under the control of the grower. However, crop nutrition and soil fertility can be managed for good yields and production efficiency The performance of improved lentils to vertisols of Haramaya and their response to phosphorus application were studied, accordingly different performance of the varieties to the agroecology as well as different response to Phosphorus were observed. The varieties' maximum yield was also recorded in different rate of P application and few of plant characters were behave differently due to P. it seems, different varieties will be recommended based on availability of the nutrient in interest (P).
