Environmental pollution is the major threat confronting the world and the rampant use of chemical fertilizers and pesticides can contribute to the deterioration of the environment. This illpractice can lead to loss of soil fertility which may have a huge impact on agricultural productivity. Vegetable wastes provide a good amount of nutrients for inhabiting microbes and thus can be a potential alternative for transforming into an organic biofertilizer. Therefore the present research work was undertaken to formulate the vegetable waste compost in association with microorganisms (Rhizobium spp., Azotobacter spp. and Lactobacillus spp.) and Spirulina that can act as a potential biofertilizer and its comparative assessment with synthetic fertilizer. The formulated compost mixtures were inoculated with variant combinations of organisms, Test Control and Control. These microbial cultures were combined with different combinations of vegetable wastes like corn and cabbage, cabbage and onion, corn and onion with soil which were utilized to formulate into a potential biofertilizer. It was observed that there was increase in shoot length (24.4cm) and root length (6.0cm) in the consortium treated plant in combination with corn+onion. The comparative assessment undertaken in the current study gave the major outcome that the formulated biofertilizer was better than the synthetic fertilizer and hence can serve as the potential substitute to the hazardous chemical or synthetic fertilizer. Towards the end the positive outcome substantiated that microbial biotechnology can be a powerful tool for the decomposition of kitchen waste into a value added material.

环境污染是世界面临的主要威胁,化肥和农药的猖獗使用会导致环境恶化。这种不良做法可能导致土壤肥力丧失,从而可能对农业生产力产生巨大影响。蔬菜废弃物为居住的微生物提供了大量的营养物质,因此可以成为转化为有机生物肥料的潜在替代品。为此,开展了与微生物(根瘤菌、固氮菌和乳酸菌)和螺旋藻结合的蔬菜垃圾堆肥的研制及其与合成肥料的对比评价研究。配制的堆肥混合物分别接种不同的微生物组合、试验对照和对照。这些微生物培养物与蔬菜废物的不同组合相结合,如玉米和卷心菜,卷心菜和洋葱,玉米和洋葱与土壤,这些被用来配制成潜在的生物肥料。玉米+洋葱组合处理植株的茎长和根长分别增加了24.4cm和6.0cm。本研究进行的对比评估得出的主要结论是,配方生物肥料优于合成肥料,因此可以作为危险化学品或合成肥料的潜在替代品。最后,积极的结果证实了微生物生物技术可以成为将厨房垃圾分解成增值材料的有力工具。关键词:微生物堆肥;蔬菜废弃物;生物肥料

The research work was conducted in the year 2017-2018 to study the “A study on disposal pattern and marketing of Saffron in Ghoryan district, Herat province of Afghanistan” The study was conducted with the objectives to find out the marketing system of saffron and marketing channels followed by the growers, producer’s share in consumer’s rupee in marketing costs and margin. For realizing the objectives of this study the researcher used interview schedule, distribute the questioner and interviews and focus discussions with the farmers, wholesalers, retailer with sample size 66 along with cooperative societies and private saffron processing companiese. The result showed that price spread was higher channel 1 followed by II, III and IV channel respectivly. Whereas producer’s share in consumer’s rupee and marketing efficiency was also higher in same trend. Saffron is plant which has volitle aroma and flavour. Hence the drying, packing, transportaion and storage cost from the place of orgin to the place of consuming also effects the marketing cost and margin.
该研究工作于2017-2018年进行,旨在研究“阿富汗赫拉特省Ghoryan地区藏红花的处理模式和营销研究”。该研究的目的是找出藏红花的营销系统和营销渠道,以及种植者、生产者在消费者卢比中所占的营销成本和利润份额。为了实现本研究的目标,研究者采用访谈计划,分配提问者和访谈,并与样本量为66的农民,批发商,零售商以及合作社和私人藏红花加工公司进行重点讨论。结果表明,渠道1的价差较大,其次是渠道II、渠道III和渠道IV。而生产者在消费者卢比和营销效率中所占的份额也在同一趋势下更高。藏红花是一种具有淡紫色香味的植物。因此,从原产地到消费地的干燥、包装、运输和储存成本也影响着营销成本和利润。

This study was carried out at the Demonstration Farm, Agricultural Research Corporation, Shambat, Khartoum North, Sudan in 2014/2015 and 2015 /2016 seasons. The objective was to come up with a compost preparation procedure to improve the quality of the compost and hence crop productivity. Farm yard (FYM) and Chicken manures (CHM) were collected from the Top Farm and the Faculty of Animal Production, University of Khartoum, respectively and were mixed at a ratio of 10:1 (FYM:CHM) and moistened to 50% of its volume. The mixed material was divided and composted into four preparations; aerobic, forced aeration at the rate of 10 CFM, anaerobic (buried in 90cm auger holes) and vermin (1kg vermin/2kg organic matter). The experiment was laid out in a completely randomized design (CRD). The composts prepared were sampled every month and analyzed for organic carbon (OC); nitrogen (N); phosphorus (P) and potassium (K). Microbiological examinations were made every month. Compost maturation was reached by reduced volume, brown color and crumbly with earthy smell. It was observed that the best and appropriate time of opening compost was after three months. The results obtained showed that the best treatment was the aerobic, followed by forced aeration in the two seasons. The results illustrated that the bacteria population was significantly (P<0.05) different from the aerobic and the vermin treatments. The nitrogen, phosphorus and potassium were significantly (P<0.05) different in the two seasons in the aerobic treatment compared with other treatments, whilst potassium and phosphorus were significantly (P<0.05) lower for the anaerobic treatment in the first season.
本研究于2014/2015和2015 /2016年度在苏丹喀土穆北部Shambat农业研究公司示范农场进行。目的是提出一种堆肥制备程序,以提高堆肥的质量,从而提高作物产量。分别从喀土穆大学动物生产学院和顶级农场收集猪粪(FYM)和鸡粪(CHM),按10:1 (FYM:CHM)的比例混合,并湿润至其体积的50%。将混合后的物料分成四种制剂进行堆肥;需氧、强制曝气(10 CFM)、厌氧(埋在90cm的螺旋孔中)和除虫(1kg害虫/2kg有机物)。实验采用完全随机设计(CRD)。每个月对堆肥进行取样,分析有机碳(OC);氮(N);磷(P)和钾(K)。每月进行微生物学检查。堆肥成熟时体积减小,颜色呈褐色,易碎,有泥土味。结果表明,开堆肥的最佳和适宜时间为3个月后。结果表明,两个季节中以好氧处理效果最好,其次为强制曝气处理。结果表明,与好氧处理和害虫处理相比,细菌数量差异显著(P<0.05)。好氧处理两季氮、磷、钾含量显著低于其他处理(P<0.05),厌氧处理第一季钾、磷含量显著低于其他处理(P<0.05)。

Traditional paired row system of mulberry plantation raised in [(3’x2’)X5’] spacing accommodating 13,888 plants/hectare as low bush plantation resulted in practical problems viz. difficult to cultivate in limited water resource, prevents mechanization, inconvenient for cultural and intercultural operations, susceptible for drought stricken conditions, involves manpower drudgery and prevents silkworm rearing during summer period due to low and poor quality leaf production. Therefore, tree mulberry farming accommodating limited number of plants grown in wider spacing supplementing limited water, manure and fertilizer inputs with reduced manpower drudgery is gaining popularity among the Southern Tropical Zones. Keeping the above thrust area of research, efforts were made to develop suitable and sustainable tree mulberry farming technology for enhanced quality leaf production was attempted. It was noticed that tree mulberry raised in wider spacing (8’x3’) accommodating 4547 plants/ha yielded higher leaf (67,072kg/ha/yr) over the traditional paired row spacing [(3’x2’)x5’] with 13,888 plants/ha (60,144kg/ha/yr) followed by (8’x5’) spacing with 2728 plants/ha (51,174kg/ha/yr). However, 10’x10’ spacing with 1093 plants resulted in 70% reduction of leaf yield (21,084kg/ha/yr) indicating that economically not viable for the welfare and benefit of sericulturist. Other plant growth and leaf quality parameters also indicated the similar trend.
传统的[(3'x2 ')X5 ']双行制桑树人工林作为低灌丛人工林,种植面积为13888株/公顷,存在水资源有限,栽培难度大,机械化程度低,不便于文化和跨文化作业,易受干旱影响,人力劳动多,产叶质量低,不利于夏季养蚕等实际问题。因此,桑树种植可以容纳有限数量的植物,种植间距更宽,补充了有限的水、粪便和肥料投入,减少了人力劳动,在南部热带地区越来越受欢迎。在坚持上述研究重点的基础上,尝试开发适宜的、可持续的桑树栽培技术,提高桑树优质产叶质量。我们注意到,与传统的双行间距[(3'x2 ')x5 '](13,888株/公顷(60,144kg/公顷/年)和(8'x5 ')(2728株/公顷(51,174kg/公顷/年)相比,更宽间距(8'x3 ')种植的桑树(4547株/公顷)产量更高(67,072kg/公顷/年)。然而,1093株的10'x10 '间距导致叶片产量减少70%(21,084公斤/公顷/年),这表明从经济上不适合养蚕者的福利和利益。其他植物生长和叶片质量参数也表现出类似的趋势。
