Abstract
A research study was conducted to find out the effect of phosphorus and potassium on seed production performance of berseem Egyptian clover (Trifolium alexandrinum L) which belongs to the family Papilionaceae. The experiment was conducted at Research Farm of Khyber Paktunkhwa, Agricultural University Peshawar, Pakistan during 2004 to 2005. The experiment was carried out in randomized complete block design (RCBD) with four replications. Treatments including phosphorus (30, 60 and 90 kg P ha-1) and potassium (0, 30 and 60 kg K ha-1) were applied to berseem. These treatments produced significant effect on the number of heads (m-2), number of seeds head -1, biological yield (kg ha-1), seed yield (kg ha-1) and thousand seed weight (g). Maximum number of heads (2430 m-2), number of seeds head-1 (41.50), biological yield (1310 kg ha-1), seed yield (240 kg ha-1) and thousand seed weight (2.18 g) were recorded in plots having 60 kg P ha-1 x 30 kg K ha-1, while minimum number of seeds (1680 m-2), number of seeds head-1 (30.06), biological yield (1072 kg ha-1 ), seed yield (120kg ha-1) and thousand seed weight (1.90g) were obtained from plots having no fertilizers (control or 0 kg ha-1). The findings of this study shows that berseem had better performance in terms of seed production when fertilized with of 60 kg P ha-1 and 30 kg K ha-1 in irrigated areas of Peshawar valley. Key words: Berseem, seed production, phosphorus, potassium.

Summary
The berseem (Tifolium alaxandrium L) is one of the most important forage legumes in Pakistan and India which belongs to the family Papilionaceae and order Leguminale. In Pakistan, major fodder crops grown in winter (Rabi) include berseem, shaftal, lucerne, oats, barley and mustard; while during summer (Kharif) the ones grown include maize, sorghum and millets These crops cover 16 to 19% of the total cropped area in the country. Improved fodder varieties are available at research level and this need to be made available to the farmers through extension department in order to exploit their full genetic potentials so as to meet the requirements of our live stock These varieties have the potential to increase fodder yields 2 to 3 times when compared to local varieties currently in use (Singh, 2000). The present study was designed to determine the effect of different levels of phosphorus and potassium in order to maximize seed production from berseem in the irrigated areas of Peshawar valley
