EFFECT OF NITROGEN FERTILIZATION AND FOLIAR ZINC SPRAYING ON THE YIELD, YIELD COMPONENTS AND SEED RECOVERY OF BERSEEM

Abstract
Domestic production of berseem seed is very low in Pakistan; therefore, we import a large quantity of seeds. Seeds of berseem can be produced with in the country for which research on seed production is preferred, as most of research work on berseem conducted on forage production only. Thus, an experiment comprising four levels of nitrogen (0. 15, 30 and 45 kg ha-1) and four levels of foliar zinc (0, 400, 600, and 800 g ha-1), was designed with the purpose to find out appropriate levels of nitrogen and foliar zinc to get maximum seed yield of berseem. The experiment was conducted at the agronomy Research Farm of The University of Agriculture Peshawar during winter 2014-2015 by using randomized complete block design replicated three times. The results indicated that both nitrogen and foliar zinc application significantly (P˂0.05) influenced fresh (13219.41 kg ha-1) and dry fodder yield (5538 kg ha-1), head m-2 (1963), number of seeds head-1 (50), biological yield (8535.4 kg ha-1), thousand seed weight (2.6 g), seed yield (261 kg ha-1), seed recovery (68%). A significant affect was recorded only by different nitrogen levels on number of flower head-1 (78) and harvest index (3.19%) whereas zinc significantly influenced plant height (80 cm). Both nitrogen and foliar zinc application increases fresh and dry fodder yield, plant height, head m-2, number of seed head-1, thousand seed weight, seed yield, seed recovery (%). It was concluded that the application of nitrogen (45 kg ha-1) and zinc (600 g ha-1) in the form foliar spraying produces maximum yield of berseem crop.
