Abstract: A field experiment was conducted at Metu Agricultural sub – centre on station in 2015 and 2016 cropping seasons to evaluate the effectiveness and economic feasibility of weed management methods on maize grain yield at Metu area. BH 661 at 25 kg/ha used as seed source. The experiment comprised of nine treatments laid out in randomized complete block design (RCBD) with three replications. The result revealed that the highest average grain yield 62.8 q/ha was obtained from Integrity EC 668g/l 1.0 liter with two supplementary hand weeding followed by 61.6 q/ha from Integrity EC 668g/l 1 liter with one hand weeding. Similarly, the minimum above ground wee dry biomass mean 0.07q/ha, 1.5 q/ha obtained from three hand weeding at 30, 60 and 90 days after planting and Integrity EC 668g/l 1.0 liter with two supplementary hand weeding respectively. Consequently highest weed control efficiency 99.93% and 98.5%obtained from the same treatment. In economic feasibility aspect the highest net benefit Accordingly the highest net benefit 61296.4 ETB ha-1 was obtained from Integrity EC 668g/l at 1.0 L/ha + two time supplementary hand weeding with 3042.86 MRR% followed by 60146.2 ETB ha-1 net benefit with 5661.90% MRR obtained from Integrity EC 668g/l at 1 l/ha + one times supplementary hand weeding whereas the minimum net benefit 50551.2 ETB ha-1 and 53224.2 ETB ha-1 obtained from one hand weeding at 30 & 454 days after planting respectively. Therefore, Integrity EC 668g/l at 1 l/ha + two times supplementary hand weeding and Integrity EC 668g/l at 1 l/ha + one time supplementary hand weeding treatment consecutively more profitable weed management practices to control weeds in maize and there by improve crop production up to 56.94% than other treatments and can be recommended for maize production at Metu area.

Abstract: Grass peas are one of the most nutritious foods and are widely harvested and consumed in many developing countries. They are an inexpensive source of protein and contain large amounts of essential amino acids. The potential of grass peas to improve food security, nutrition and household income generation remains largely untapped. However, the naturally occurring amino acid β-diaminopropionic acid (β-ODAP) leads to limited neurotoxic activity. Lathyrus sativus β-ODAP exists in two isomers (α and β isomers) in nature. The α isomer accounts for approximately 5% of the total ODAP content and is less toxic, but the β isomer is also more toxic. Decreased β-ODAP levels through food processing such as overnight soaking, cooking bean sprouts, fermentation, and roasting. Most food pretreatment processing methods can effectively improve the nutritional quality of grass bean grains and reduce anti-nutritional factors. Grass peas, a variety of traditionally treated seeds, serve as a staple food for poor farmers in countries such as Ethiopia and are primarily consumed during times of drought and famine. Grass pea seeds are valued as a nutritious staple food and feed plant mainly due to their high protein content.

Abstract: Comparing hybrid maize to open-pollinated varieties, the former is widely recognized for its higher producing capacity. However, the production potential of hybrids varies depending on the region and the season. Maize inbreed lines are relatively week and low in yield when compared to hybrid formed from them and open pollinated variety. Hence their seed production is challenged by weather condition like rain fall and temperature. This experiment was conducted on thirteen released inbridlines to calculate the Amount of growing degree days and production potential using a randomized complete block design with 3 replications. The mean GY for inbred lines was 4.08t/. L10 had the highest yield (5.53 t/ha), followed by L13 (5.18 t/ha) and L4 (5.13t/ha). L12, L7 and L3 had grain yield above the mean with the mean values of 5.03, 4.14, and 4.10 (t/ha). The ANOVA for Anthesis-Silking Intervals (ASI) showed highly significant differences (p< 0.01). Among inbred parents, L7, with an average of (6.66 days) had the longest ASI followed by L5, and L12 with five days of ASI. And The mean of ASI was four days for L1, L3, L4 and L10. The mean of ASI was 3.58 days, which has highly significant effect on yield. The shortest ASI was observed for L9 with (1day) followed by L6 (1.33 days), L2 (2days) and L8, L11, L13 with 3days. L10 had the highest score of Growing Degree Days (GDD) (°C) for DA and DS with 957.3 and 998, respectively. Whereas the lowest scores of GDD (°C) for DA and DS, observed on for L2, Were 815°C and 835°C), respectively.
