Simulating the effect of emex australis densities and sowing dates on agronomic traits of wheat
Parents have a right, as experts on their own children, to pursue the least restrictive environment with supports and services for their children to successfully achieve their individual goals. They will always have far longer and greater responsibility and interest in their child’s future. This study discussed the current research literature related to the rehabilitation of physically handicap...
متن کاملEvaluation of Tillage, Nitrogen Fertilizer and Crop Residue Management on some Agronomic Traits of Soybean
This study setout to investigate the effect of wheat residue, tillage, and nitrogen fertilizer management on some agronomic traits of soybean as a split split plot based on randomized complete block design with three replications. The main plots included wheat residue management: collecting and leaving residue and sub plot included tillage (without tillage and conventional tillage), and the sub...
متن کاملTropical Legume Crop Rotation and Nitrogen Fertilizer Effects on Agronomic and Nitrogen Efficiency of Rice
Bush bean, long bean, mung bean, and winged bean plants were grown with N fertilizer at rates of 0, 2, 4, and 6 g N m(-2) preceding rice planting. Concurrently, rice was grown with N fertilizer at rates of 0, 4, 8, and 12 g N m(-2). No chemical fertilizer was used in the 2nd year of crop to estimate the nitrogen agronomic efficiency (NAE), nitrogen recovery efficiency (NRE), N uptake, and rice ...
