A study was conducted to identify adaptable, high biomass, good quality and seed yield of Pegeon pea cultivars at Adola sub-site of Bore Agricultural research center. Four pegeon pea cultivars Tsigas, Degagsa-75, Belabas-27 and 16555 were tested in RCBD with three replications. The analysis of variance revealed that significant (P<0.05) differ in days to 90% maturity were observed among cultivars. Among tested cultivars, Belabas 27 was significantly earlier (162 days) to maturity, while the late matured cultivar was Degagsa (203 days). Analysis of variance showed highly significant differences (P<0.01) were observed among cultivars for the number of primary branches per plant. A higher branch number was recorded for Tsigas cultivar (21.6) whereas the lowest branch number was obtained from cultivar Degagsa-75 (9.75). The cultivars were significant (P<0.05) differ for pod length. The long pod was recorded from cultivar 16555 (5 cm) while the short pod length was recorded from cultivar Belabas -27 (3.14 cm). Cultivars were significant (P<0.05) varied for plant height. The long plant height was measured from cultivar Degagsa-75 (159.75 cm) followed by Tsigas (104.9 cm) whereas the short pant height was obtained from cultivar Belabas-27 (78.63 cm). Significant variations (P<0.05) in biomass yield between genotypes were observed (Table 2). Superior biomass yield was produced from Tsigas cultivar (2.17 ton/ha) followed by cultivar 16555 (1.27 ton/ha) while the low biomass yield was obtained from Degagsa-75 cultivar (0.97 ton/ha). In addition to the nutritional values were promising particularly the crude protein (CP) content in cultivar Tsigas. Based upon its adaptability, high biomass yield, seed yield and good CP of cultivar Tsigas and 16555 are recommended for further promotion in the midland of Guji zone and similar agro-ecologies. © International Journal of Ground Sediment & Water, ©Sun Jichao.

This work contributes to the monitoring of water and sediment heavy metal pollution of Are dam Rimi Local Government Area, Katsina State Nigeria, using Atomic Absorption Spectrophotometry. From the results, Pb, Ni, and Cd level in the water sample are above the safety limit. The water Pollution index (PI) and Metal index (MI) indicate a threshold threat to human and aquatic life’s utilizing the water, the Geo accumulation index (I-geo), Enrichment factor (EF), Contamination factor (CF), and Potential ecological risk index (PERI) values in sediment sample indicate unpolluted (class 0) with minimal enrichment, low contamination level, and low ecological risk respectively. The target hazard quotient (THQ) and Health risk index (HI) values for adults and children of the heavy metals in the water sample were below 1 suggestive of no non-carcinogenic adverse health hazards to the population. The Incremental lifetime cancer risk (ILCR) values were at the threshold level of 1.0 × 10−4 for Pb in children and Cd in adult and above the threshold for Cd in children and Ni in adult and children in the water sample, pointing to potential cancer risk to both adults and children from drinking the water sample. © International Journal of Ground Sediment & Water, ©Sun Jichao.
