Abstract: Inadequate disposal of coffee waste have led to serious environmental problems, and requiring efficient measures to recycling these wastes. Composting is thus, environmental friendly option for utilization of this waste. Therefore this study was to evaluate some physicochemical parameters of compost produced from coffee pulp with cow dung and enset leaf (Ensete ventricosum). Treatments were built in randomized complete block design with proportions of treatment one (90% of coffee pulp and 10% of top soil), treatment two (65% of coffee pulp, 25% of cow dung and 10% of top soil), treatment three (65% of coffee pulp, 25% of enset leaf and 10% of top soil) and treatment four (50% of coffee pulp, 20% of cow dung, 20% of enset leaf and 10% of top soil). It conducted for 80 days, from December 28, 2018 to March 17, 2019. Some physicochemical parameters were determined at 25, 55 and 80 days of composting and mean value of bulk density, moisture content, pH, electric conductivity, organic matter, total organic carbon, total nitrogen, total phosphorous, total potassium and C/N ratio were 483.6kg/m3–487.11kg/m3, 50.74%–52.43%, 7.45-8.36, 3.08mS/cm-3.42mS/cm, 45.26%-46.99%, 26.19%-27.27%, 1.54%-1.61%, 0.41%-0.59%, 0.75%-1.15% and 17.5-18.44 respectively. pH of treatment four was more neutral than from all and total potassium of treatment four was more appropriate for nutrient content than the rest. Thus, experimental results showed that treatment four was better for quality compost preparation and provides baseline information for coffee pulp waste management simultaneously.

Abstract: The present study was conducted in 100 promising chickpea (Cicer arietinum L.) genotypes using Mahalanobis D2 Statistics. The divergence (D2) analysis revealed that the 100 chickpea genotypes were grouped into nine significant clusters. The intra-cluster distance values were ranged from 5.3 (cluster IV) to 77.8 (cluster VIII). The highest inter cluster distance were observed between genotypes of cluster I and cluster VIII (874.5) followed by cluster I and cluster II (837.4), cluster I and cluster V (759.3), cluster I and cluster III (480.4), cluster I and cluster VII (413.7), cluster IV and cluster VIII (390.9), cluster II and cluster IV (377.5) and Cluster II and cluster VI (309.4), cluster I and cluster IX (300.4), cluster I and cluster IV (295.2), cluster IV and cluster V (287.2). The lowest inter cluster distance (81.6) were found between cluster VI and cluster IX followed by cluster II and cluster VII (81.8), cluster III and cluster VII (87.4), cluster IV and cluster VI (90.6), cluster II and cluster III (93.6), indicating existence of closer proximity between these clusters. Based on inter cluster distances and Per se performance, hybridization among the genotypes from these clusters which showed maximum distance might produce high yielding varieties having broad genetic base. In general the genotypes JV-11, IE-16-059/1, iccx-090013-f2-p215-BP, DZ-2012-CX-0028, iccx-060045-f3-p5-BP, iccx-060039-f3-p182-BP may serve as potential parents for grain yield. IE-16-109/2, iccx-0900013-f2-p107-BP, icc-6279, JG-62, icc-15614, IE-16-059/2 can be also a parental line for earliness, while iccx-090013-f2-p265-BP, iccx-090013-f2-p107-BP, iccx-090013-f2-p103-BP, iccx-090013-f2-p215-BP for hundred seed weight. IE-16-109/2, icc-14778, icc-510, DZ-2012-CK-0253, icc-5135 also be a potential parental line for quality character of crude protein. Generally genotypes listed above may serve as a parental lines for hybridization program in the improvement of chickpea grain yield and its contributing trait.
