Bread wheat is the most important cereal food grain crops in the world which can be grown under diverse agro ecology. However, its productivity has been limited due to various abiotic and biotic factors including weeds. The aim of the study was to evaluate the effects of post emergence broad leaf herbicides application on weed management and productivity of wheat. Four types of herbicides 2,4-D1lt ha,Pyroxulam 0.5lt ha, Florasulam 100ml ha and Florasulam + Amirpyrolid 33gm haalong with weedy check that were laid out in Randomized Completely Block Design with three replications. A total of identified 12 weed species were recorded 86 % broad and 14 % grass weeds. Relative weed density also indicated that the field was highly infested by Galinsoga pulviflora Cav. but the lowest infestation of Guizotia scabra(Vis) Chiov was recorded in the field. Results also revealed that significant effects of post emergence herbicides application on some traits studied but there is no significant difference among tested herbicides on plant height, stand count, spike length, number of seeds per spike and thousand grain weights except for weedy checks. The minimum dry biomass weeds (111.00 kg ha) and the highest weed control efficiency (79.63%) were recorded from the Pyroxulam. The highest number of productive tillers(131.66m),stand count(413.00m),seeds per spike(71.58), thousand grain weight (42.00g),grain yield (3928.25 kgha) and biological yield (8693.3kg ha) were recorded from Florasulam + Aminopyrolid while the lowest values were observed from the weedy check. Therefore, it can be concluded that Florasulam + Aminopyrolid effectively managed weeds and gave maximum yield which could be recommended for the test environment.
面包小麦是世界上最重要的谷类粮食作物，可在多种农业生态条件下种植。然而，由于各种非生物和生物因素，包括杂草，其生产力受到限制。本研究旨在评价羽化后施用阔叶除草剂对小麦杂草管理和生产力的影响。4种除草剂2,4- d1lt ha,Pyroxulam 0.5lt ha, Florasulam 100ml ha和Florasulam + Amirpyrolid 33gm，并进行杂草检查，随机完全区组设计，3个重复。共鉴定出12种杂草，其中阔杂草占86%，草杂草占14%。相对杂草密度也表明，该地区灰树花高发。但在田间记录中，黄鼠狼的侵害率最低。除草后施用除草剂对部分性状有显著影响，但在株高、林分数、穗长、穗粒数和千粒重等性状上差异不显著。干生物量杂草最少(111.00 kg ha)，防杂草效率最高(79.63%)。有效分蘖数(131.66m)、林分数(413.00m)、穗粒数(71.58粒)、千粒重(42.00g)、籽粒产量(3928.25 kgha)和生物产量(8693.3kg ha)在Florasulam + Aminopyrolid试验中记录最高，而杂草试验记录最低。综上所述，Florasulam + Aminopyrolid能有效治理杂草，产量最高，可推荐用于试验环境。

Long pepper cuttings are traditionally planted in a trench & covered with plastic sheet to get large number of transplantable seedlings. But the success of the transplant is often low hence; it is common to retain cuttings for more than a year to synchronize their stage of transplanting with start of main rainy season. This requires extra costs for nursery operation & maintenance that needs further research focus to fill the gap alleviated by identifying best growing media, suitable type of cutting type & identifying appropriate watering frequency. The present study was conducted at Jimma Agricultural Research Center (JARC) to investigate the influence of rooting media, cutting types and watering frequency on dry matter production of long pepper cuttings. Four types of media, composed of sub soil(ss), top soil(ts), farmyard manure(fym) and fine sand with the following proportion, 2top soil + 1farmyard manure + 2fine sand recommended for coffee cutting , 6top soil + 3farmyard manure + 2fine sand recommended for coffee nursery, 1/3 ss upper + 2top soil + 1farmyard manure + 1fine sand recommended for tea media and 2top soil + 1farmyard manure + 1fine sand recommended for coffee nursery, three level of cutting type soft wood (sw), semi hard wood(shw) and hard wood (hw) and four level of watering frequency were combined in split plot design with three replications, where four watering frequency levels were assigned to main plots, four media type levels were assigned to sub plot and three types of cutting (soft wood, semi hard wood and hard wood) levels were assigned to subsub plot were combined with factorial arrangement (4 x 4 x 3) with 48 treatments. Data was collected for root and shoot dry matter production after six months of planting. The analysis of variance for average dry shoot weight was significantly influenced by watering frequency, rooting media and cutting type. The main effect of watering frequency, rooting media, the interaction effect of watering frequency with rooting media, watering frequency with cutting type and media with cutting type, the three way interaction effect of watering frequency, rooting media and cutting type were very highly significant (P < 0.001) difference. Attention should also be given in selecting the cutting type and position on the stock plant while preparing the cuttings.

International rice experts argue that Green Revolution technology negatively impacts soil physicalchemical conditions and calls thwas phenomenon soil soil fatigue or soil sickness. There was a tendency for input efficiency to be lower. To achieve the same level of rice production, more inputs were needed, and the rate of increase in production tends to be sloping, even decreasing (Fagi et.al, 2009). The interaction of the contribution of water irrigation x superior varieties x fertilizing accounted for 75%. So, even though irrigation water contributes the most, but it does not have a big impact if it was not planted with superior varieties, and superior varieties need high-dose fertilization. In total irrigated rice accounts for around 54% of national rice production (FAO, 1996; Huke and Huke, 1998).
国际水稻专家认为，绿色革命技术会对土壤的物理化学条件产生负面影响，并将这种现象称为土壤疲劳或土壤疾病。投入效率有降低的趋势。为了达到相同的水稻产量水平，需要更多的投入，产量的增长率趋于倾斜，甚至下降(Fagi et.al, 2009)。灌水+优势品种+施肥互作贡献占75%。因此，即使灌溉用水贡献最大，但如果不种植优良品种，影响也不大，而优良品种需要大剂量施肥。总的来说，灌溉水稻约占全国水稻产量的54%(粮农组织，1996;Huke and Huke, 1998)。

There are two types of phospholipids present in vegetable oils namely the hydratable and nonhydratable. Simple water degumming will not remove non-hydratable gums. High phosphatide containing oil like soybean oil (700ppm) water degumming alone is not satisfactorily to reduce the phosphatide content below 10ppm. Therefore enzymatic process is used together with water degumming. Degumming is an important step in oil refining process and removes phosphatide (gum) along with some other unwanted minor compounds without destroying the beneficial ones.

The experiment was executed to analyses seed yield and related traits stability parameters for ten genotypes of linseed at Holeta, Kulumsa, Bekoji and Asassa representative areas of central highlands of Ethiopia. The experiment was carried out in a Randomized complete block design. Stability parameters for ten genotypes of linseeds were evaluated and assessed using three different stability methods. The investigation included six characters ( seed yield per plot, oil content, oil yield, date of flowering, date of maturity and plant height). Results revealed significant genotype × environment interactions were detected for seed yield, oil content, date of flowering and plant height studied traits and the response to environmental changes of each genotype differed as indicated by M.S. pooled deviation and heterogeneity items. Wider ranges of regression coefficient values were observed from the studied stability methods suggesting possibility of selection for specific genotypes patterns. Two genotypes PGRC/E10306 X Chilalo Y/3 and Omega X CI-1525/Y/44 were most stable for studied characters in the four central highlands of Ethiopian environments.

Weeds are important hosts of insect pests and pathogens in agroecosystems. Van Emden and Dabrowski (1997) cites 442 references relating to weeds as reservoirs of pests. More than seventy families of arthropods affecting crops were reported as being primarily weeds associated (Bendixen and Horn, 1981). Many pest outbreaks can be traced to locally abundant weeds belonging to the same family as the affected crop plants. Many insect pests are sufficiently polyphagous and thus, weeds unrelated to the crop may also be pest reservoirs. For example, Aphis gossypii feeds on over twenty unrelated weed species within and around cotton fields. Weedy plants near crop fields can provide requisites for pest outbreaks. Gliessman (2001) reported that weed borders are used in an agroecosystem to attract insects, facilitating colonization in the adjacent cauliflower crop.

Pomegranate (Punicagranatum L.), from family Punicaceae, has been traditionally used for thousands of years as a medicinal fruit Fig.1. Mediterranean regions (including Iran, India and Pakistan) have the highest rate of pomegranate cultivation in the world. Based on excavations of the Early Bronze Age (3500–2000 BC), it is believed that the pomegranate was one of the first cultivated fruits for its beneficial properties. Pomegranate was held sacred by many of the world’s major religions and nations.
