  Grain yield potential in relation to other important agronomic characters of 13 graypea (Pisum arvense L.) germplasm during rabbi 1999-2000 was investigated in order to identify the high yielding promising germ plasm for further studies. Germplasm GP-01 ranked first by producing maximum yield of 1000 kg/ha, while germplasm GP-12 with 9444 kg/ha ranked second. Minimum yield of 49 kg/ha was obtained by GP-09, followed by GP-02 with 67 kg/ha. The germplasm in group 1 viz. GP-01 and GP-12 gave 63 and 93% higher yield than group II and group III, respectively. The higher yield in the germplasm of group I, was mainly due to more branches and pods per plant, pod length and seeds per pod and maximum dry matter than the germplasm of group II and III. GP-01 and GP-12 are the most promising germplasm recommended for further investigation.

  Total four experiments were conducted in the different ecological zones of the province i.e. Southern, Northern and Central zones in order to find out the suitable time of earthing up for obtaining maximum yield of sunflower crop in NWFP. The average data of four locations revealed that sunflower gave highest yield if the earthing up is completed before bud formation. However, seed yield is decreased when earthing up is delayed. It is, therefore, recommended that earthing up before bud formation is necessary for obtaining higher returns from sunflower with respect to seed yield.

  Grain yield potential in relation to other important agronomic characters of 1 1 vegetable pea (P. sativum L.) germplasm was tested during rabi 1999-2000. Germplasm PS-02 ranked first by producing maximum yield of 3167 kg ha-1, while germplasm PS-10 with 3056 kg ha-1 ranked second. Minimum yield of 91 1 kg ha-1 was obtained by PS-07, followed by PS-11 with 1389 kg ha-1 Average grain yield of group I was 45% higher than the average yield of group II. The average values of grain yield decreased in descending order from 2756 to 1513 kg ha-1 in group I and group II, respectively. Similarly the average values of plant height, branches per plant, dry matter yield and pods per plant decreased in descending order i.e. 1 37 to 89 cm, 2.5 to 2.2, 8490 to 3759 kg ha-1 and 1 1 to 7 in group I and group II, respectively and showed positive relationship with grain yield. The average values of pod length and harvest index increased in descending order i.e. 4.2 to 4.9 cm and 31.7 to 43.9 % in group I and group II, respectively. The relationship of days to maturity, seeds per pod and 100-seed weight with grain yield was not very well established. The association of harvest index with dry matter yield was significantly negative.

  In order to test the correlation between grain yield and yield components five promising mungbean (Vigna radiata L.) germplasm i.e. two each from Swat, Dir and one from Chitral were planted at the Research Farm of NWFP Agricultural University Peshawar on May 22, 1997. Grain yield varied significantly from 719 (CH.MB.1) to 1121 kg/ha (D.MB.7). Grain yield showed positive correlation with pod length, pods per plant, 100-seed weight and harvest index and negative correlation with days to maturity, plant height, branches per plant, seeds per pod and dry matter yield. Dry matter yield showed positive correlation with days to maturity, plant height and branches per plant and negative correlation with pods per plant. Pods per plant showed negative correlation with days to maturity, plant height and branches per plant. Days to maturity showed positive correlation with plant height and branches per plant. The correlation between plant height and branches per plant was also positive.

  An experiment consisting of 11 blackbean (Vigna mungo (L.) Hepper) germplasm was carried at the Research Farm of NWFP Agricultural University Peshawar on June 9, 1999, to know the yield potential of these germplasm in relation to other important agronomic characters. Germplasm BB14 ranked first by producing maximum grain yield of 844 kg ha -1, followed by germplasm BB7 (755 kg ha-1). Average values of grain yield decreased in descending order from 799 kg ha -1 in group I to 375 kg ha -1 in group II and then further decreased to 243 kg ha -1 in group III. Similarly, the average values of days to maturity, plant height, branches and pods per plant, 100 seeds weight, dry matter yield and harvest index decreased in descending order, and showed positive association with grain yield.

  Grain yield potential in relation to other important agronomic characters of 20 lentils (L. culinaris) germplasm collected from FATA (Federally Administered Tribal Areas) and neglected pockets of NWFP was tested at the Research Farm of NWFP Agricultural University Peshawar during 1999-2000 growing season. Based on the grain yield potential, the germplasm were divided into three groups in descending order.

Germplasm LT-05 ranked first by producing maximum yield of 1459 kg ha–1, while germplasm LT-03 with 1070 kg ha–1 ranked second. Minimum yield of 180 kg ha–1 was obtained by LT-04, followed by LT-01 with 209 kg ha–1% The germplasm in group I viz. LT-05 and LT-03 gave 64 and 82% higher yield than group II and group III, respectively. The average values of grain yield decreased in descending order from 1264 kg ha–1 in group 1 to 456 kg ha–1 in group II and then further decreased to 231 kg ha–1 in group Ill. Similarly, the average values of branches per plant 100-seed weight, pods per plant and harvest index decreased in descending order and showed positive relationship with grain yield. The association of days to maturity, plant height, and dry matter yield with grain yield was negative because their average values increased in descending order in group I to group III.

  More than 50 germplasm of common beans (P. vulgaris L.) collected from FATA (Federally Administered Tribal Areas) and neglected pockets of NWFP were evaluated at the sub-Research Station of Kalam-Swat during summer 1999. The grain yield performance of 25 each yielding germplasm including 9 from Swat (CB-01, 03, 07, 09, 11, 13, 16, 17 and 39), 4 each from Tirah (CB-15, 31, 32 and 33) and Gilgit (CB-08, 18, 19 and 25), 3 from Dir (CB-02, 06 and 14), 2 each from North Waziristan (CB-05 and 15) and Chitral (CB-10 and 20) and one from Mansehra (CB-04) in relation to other important agronomic characters was tested again at the sub-Research Station of Kalam-Swat during summer 2000. Based on the grain yield potential, the germplasm were divided into three groups in descending order. Germplasm CB-16 ranked first by producing maximum yield of 3457 kg ha-1, followed by germplasm CB-09 with 3086 kg ha-1 while, minimum yield of 1111 kg ha-1 was obtained by germplasm CB-25. Average grain yield in groups decreased in descending order from 3003 kg ha-1 in group I to 2356 kg ha-1 in group II and then further decreased to 1609 kg ha-1 in group III. Similarly the average values of 100-seed weight, pods per plant and harvest index decreased in descending order and showed positive relationship with grain yield. Plant height and branches per plant showed positive association with dry matter yield.

  Grain yield potential of 20 cowpea (Vigna unguicalara (L.) WaIp) germplasm collected from FATA (Federally Administered Tribal Areas) and neglected pockets of NWFP was tested at the Research Farm of NWFP Agricultural University Peshawar during summer 1997. Based on the grain yield potential, the germplasm were divided into three groups in descending order.
Germplasm SW.C.31 ranked first by producing maximum yield of 2028 kg/ha, while germplasm SW.C.8 with 1724 kg/ha ranked second. Minimum yield of 22.7 kg/ha was obtained by CH.C.302, followed by SW.C.15 with 26.7 kg/ha. The germplasm in group I viz. SW.C.31, SW.C.8 and MN.C.1 gave 95 and 98% higher yield than group II and group III, respectively. The higher yield in the germplasm of group I, was mainly due to more branches and pods per plant, pod-length and seeds per pod, heavier seeds and maximum dry matter than the germplasm of group II and III and vice versa.
