“…The result of this study was in line with that of Osman and Mohamed (1981) who reported that abundant supply of seed rates delay physiological maturity in wheat. The result was also in agreement with Seleiman et al (2010) who reported that increasing seeding rates from 250-400 mG 2 grains prolong the number of days from sowing to maturity of wheat. In contrast, Melaku (2008) reported that increasing levels of seed rate promoted early physiological maturity of tef.…”

“…Similar result was obtained by Salem (1999) who found that increasing seeding rate from 60 up to 120 kg haG 1 delayed the flowering and maturity of wheat crop. Likewise, Seleiman et al (2010) reported that increasing seeding rates from 250-400 mG 2 grains caused a significant increase in the number of days from sowing to 50% heading in wheat. In contrast, Gafaar (2007) found that increasing sowing density from 200 up to 400 grains per meter square in wheat crop significantly decreased the number of days to 50% heading.…”

A B S T R A C TWith the objective of determining the effect of seed rates on the growth parameters, yield components, yield and protein content of bread wheat varieties, a study was conducted at Kulumsa Agricultural Research Center from July to November 2012. Four varieties (Digalu, Danda'a, Kakaba and Shorima) and five seed rates (100, 125, 150, 175 and 200 kg haG 1 ) and RCBD with three replications were used. The results showed that days to 50% heading, days to 90% physiological maturity, plant height, spike length, hectoliter weight and Harvest Index (HI) were affected highly significantly (p<0.01) by the main effects of variety and seed rate whereas, grain protein content was affected highly significantly (p<0.01) only by variety and above ground dry biomass yield was affected highly significantly (p<0.01) only by the main effect of the seed rate. Furthermore, the interaction effect of variety and seed rate significantly affected thousand kernels weight, number of effective tillers and number of kernels per spike and grain yield. The use of 150 kg haG 1 seed rate for variety Shorima resulted in highest thousand kernels weight (39.48 g), number of kernels per spike (60.23) and grain yield (5339.3 kg haG 1 ). From the result of this study, the use of 125 kg haG 1 seed rate for variety Danda'a; 150 kg haG 1 for varieties Shorima and Kakaba and 175 kg haG 1 for variety Digalu were identified for good crop stand and finally the yield.

“…Similarly, Iqbal et al, (2012) also found that biological yield was increased as seeding rate increased from 125 kg ha -1 to 150 and 175 kg ha -1 . Moreover, Seleiman et al (2010) confirmed that increasing seeding rates up to 350 or 400 grains m -2 increased grain, straw and biomass yields.…”

A field study was conducted at Kulumsa Agricultural Research Center from June to November 2018 croping season, with the objectives of to determine the optimum plant population rate by identifying the most cost-effective bread wheat variety. Three bread wheat varieties (Shorima, Dendea and Hidassie representing different seed sizes of small, medium, large respectively and four plant populations of 250, 300, 350 and 400 seeds m-2 were tested. The main effect of varieties on days to 50% of heading, days to 90% of maturity, thousand kernel weight and hecto liter weight showed significant (p<0.01) varitions, while number of tillers and spike length indicated statisticaly significant (p<0.05) variations. The use of 300 seeds m-2 plant populations for the variety Hidassie resulted in highest seedling number (25.33), of tillers (7.67), days to 50% of heading (61), days to 50% of maturity, (115), spike length, (7 cm), thousand kernel weight (47.28 gm), hecto liter weight (77.67 kg/hL). The interaction effects of variety & plant population on harvest index, indicated significanct (p<0.001) variation, while grain yield showed statisticaly significant (p<0.01) variation, likewise biomass yield and straw yield indicated significant (p<0.05) variations. The harvest index, resulted in (43.63%), while grain yield is (4070 kg ha-1), similarly biomass yield and straw yield are (10994 kg ha-1) and (5275 kg ha-1) respectively, and it suggests that these traits are generally inhenced by the genetic makeups of the variety Hidassie. Economic analysis using partial budget procedure was performed on grain yields to determine the treatment with most profitable returns. The beneficial marginal rate of return (795%) and benefit cost ratio (7.57) was obtained from the variety Hidassie at a plant populations of 300 seeds m-2 follwed by a marginal rate of return (899%) and benefit cost ratio (7.55) were also recorded again from the variety Hidassie at plant populations of 250 seeds m-2. So the most cost-effective variety and plant population level for farmers with low cost of production and higher benefits were identified to be the variety Hidassie at the plant population level of 300 seeds m-2 in the rain fed cropping season is identified as low cost of production with highest benefit and can be recommended as 1 st option for the producers of wheat crop. The plant populatios of 250 seeds m-2 for variety Hidassie was also cost-effective with highest net-benefit and can be recommended as 2 nd option. However, since this study was only at one location for a single croppingseason, it is advisable to repeat the experiment across locations, soil type, and over-seasons to mak agronomically consistent recommendations and economically feasible levels of plant populations for bread wheat.

“…Gafaar (2007) also stated that increasing sowing density from 200 up to 400 grains m -2 significantly decreased spike length. Similarly, Seleiman et al (2010) reported that the longest spikes were obtained from 250 and 300 grains per m 2 but without significant differences between both of them.…”

Rice (Oryza sativa L.), is one of the most important food crops and is considered as a major source of calories for more than half of the global population (Carrijo et al., 2017), covers 11% of total arable land (Khush, 2005). Rice has become a commodity of strategic significance across many African countries (Hegde and Hegde, 2013). It is also the most rapidly growing food sources across the continent due to the great urbanization in Africa more than any other region in the world. Rice consumption is increasing faster than that of any other food staple in Africa at about 5.5% per year (2000-2010 average). This increase is driven by urbanization and related changes in eating habits, and population growth (Seck et al., 2012).Africa has sufficient land and water resource to produce enough rice to feed its own population and, in the long term, generate export revenues. Rice cultivars, rice-based cropping systems and the rice itself will, however, have to undergo adaptations and improvements in order to meet future demands for both food security of the growing population and environmental conservation (Asch and Brueck, 2010). Rice productivity in Africa is generally low about 1 t ha-1 in uplands, 1 to 2 t ha-1 in rain fed lowlands and 3 to 4 t ha-1 in the irrigated zones and a range of factor explains this low productivity (African Rice, 2010). Ethiopia has a huge potential in both rain-fed and irrigated areas for rice production, which is, estimated about thirty million ha (MoARD, 2010; CSA, 2012) According to the National Rice Research and Development Strategy of Ethiopia, the trend in the number of rice producing farmers, area allocated and production showed high increase especially since 2006 (NRRDSE, 2009). Area rose from 6,000 hectares in 2005 to nearly 222,000 hectares in 2010 and paddy production from 15,460 tons to 887,400 tons, at the same time, the number of rice farmers increased from 18,000 to more than 565,000 (MoARD, 2010).At the Fogera plain, rice plays an important role in relaxing the problem of food-insecurity of the farming community. Besides, rice is among the target commodities
