Two field experiments were carried out at the
agricultural Research and Experimental Station, Faculty of Agriculture at Moshtohor, Qalubia, Egypt, during 1984/85 and 1985/86 seasons to study the effect of irrigation number and NP fertilizer treatments on lentil yield and its component. Each experiment included 24 treatments which were the combination of four irrigation treatments and six NP fertilizer treatments. The results showed that, by increasing irrigation frequency up to three times significantly increased plant
eight, number of branches/plant, number of pods/plant, ‘umber of seeds/pod, number of seeds/plant, yields of seeds, straw, biological and protein/fad, in the two successive ;seasons. Harvest index was significantly increased with increasing irrigation number up to two times in both casons. On the other hand, irrigation number had no effect in protein (%) and phosphorus content of seeds. In the both seasons, plant height and number of branches er plant were significantly affected with fertilization. increasing levels of N and P up to 15 kg N + 48 kg P205/f ad. )roduced higher values of seed yield/fad, and P content
.n lentil seeds in both seasons, also harvest index and rotein (%) in the first season only. The effect of the interaction between number of irrigaions and NP fertilizers was not significant in all studied haracters, |
