This study used an expert consensus Delphi technique in three rounds to identify drivers and barriers for organic rice production in the Guilan Province, Iran. The Kendall’s coefficient of concordance was used for assessing experts’ consensus. Informing about the benefits of organic rice consumption and obtaining an ID card for eco-labelling of organic rice by governmental regulatory bodies were the most important drivers for organic rice farming. On the other hand, the high cost of inspection and supervision of organic farms by the Iranian Organic Association and the lack of attention to the role of branding in the promotion of organic rice consumption were the main barriers for organic rice farming. In addition, farmers’ risk aversion due to reliance on rice as the only source of annual income and thus farmers’ economic dependence on rice was another important barrier. The findings of this study highlighted the vital role of the government and the agricultural extension agencies in promoting organic rice production in Iran. It is recommended that the government should consider providing direct incentives to organic rice farmers and extension services should support organic farmers to maintain or enhance grain yields.","PeriodicalId":8904,"journal":{"name":"Biological Agriculture & Horticulture","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2020-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/01448765.2019.1698464","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45045923","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Selected biocontrol organisms, including two naturally occurring hypovirulent strains of Rhizoctonia solani (Rhs1A1 and Bs69) and a commercially available Bacillus subtilis (GB03), were evaluated, both individually and in combination, for control of soilborne diseases of potato under organic production practices over three field seasons in Maine. Varying rainfall conditions over the 3 years significantly affected crop growth, tuber yield, and disease development. However, multiple biocontrol treatments resulted in significant reductions in black scurf and common scab under a variety of environmental conditions, reducing incidence and severity of each by 15–47%. Most biocontrol treatments reduced black scurf, but only specific treatments reduced common scab and silver scurf (by 15–40% and 16–24%, respectively). Combinations including both a hypovirulent strain and GB03 tended to be the most effective treatments overall. Although tuber yield varied greatly by year, Rhs1A1 and GB03 treatments, as well as combinations, increased yield by 11–37% over all three seasons. Use of hypovirulent R. solani, along with other biocontrol organisms, may provide reductions in soilborne diseases and enhanced yield in organic potato production.","PeriodicalId":8904,"journal":{"name":"Biological Agriculture & Horticulture","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2020-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/01448765.2019.1706636","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42404552","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Single node stem cuttings were treated with rooting preparations containing either 0.4% IBA (Ukorzeniacz Aaqua) or 0.2% NAA (Ukorzeniacz Baqua) or with biostimulants Bio Rhizotonic, Root JuiceTM or Bio Roots. The phenological stage of the stock plant shoots had an important role in the propagation of the cultivars. Effects of IBA, NAA and the biostimulants depended on the phenological stage and the cultivar. Cuttings of all cultivars from shoots with closed flower buds had good rooting ability despite low concentrations of total soluble and reducing sugars in the plant tissue. In Hurdals and Maiden’s Blush, none of rooting stimulators improved the rooting percentage in cuttings from shoots collected at 7–14 days after petal fall, which had a low rooting ability. Concentrations of reducing and total carbohydrates in leaves and shoots of cuttings harvested at 7–14 days after petal fall were not correlated with the rooting parameters.

For most species, seed-based multiplication is effective and convenient, but for rosemary, seed germination is a problem due to the mucilaginous seed coat, and sometimes the germination is no more than 10–20% resulting in non-uniform crop establishment. This investigation was carried out to improve seed germination by using low-cost organic seed priming techniques. Eleven pre-sowing seed treatments were tested, based on locally available resources, including: soaking seeds in water (cold and hot), bovine urine (5%, 10%, 15% and 20% concentration), bovine dung slurry, buttermilk, compost tea and Agnihotra ash, and comparing with an untreated control. All the pre-sowing seed treatments increased the percentage of seed germination in rosemary compared with the control, except buttermilk, which had an adverse effect. Among the different treatments, seed germination was significantly increased to 46.7% for seeds treated with bovine dung slurry and to 42.0% for seeds treated with bovine urine5.0%, compared with those in the control where the germination was 9.7%. The bovine dung slurry treatment also recorded uniform and early germination (9 days for initiation and completion at 43 days) resulting in a significantly higher rate of germination (1.4) than the control. The number of leaves, the root length and the seedling vigour were also recorded to be the highest for seeds treated with bovine dung slurry, followed by bovine urine5.0%.","PeriodicalId":8904,"journal":{"name":"Biological Agriculture & Horticulture","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2020-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/01448765.2019.1649193","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44921187","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Notably, horn-manure preparation (HMP) is fermented cow manure sprayed at low concentrations onto biodynamically cultivated fields. The present study investigated the effect of HMP on the growth of garden cress (Lepidium sativum L.) cultivated in a bioassay (randomized block design, n = 20). Seedlings were cultivated in a water medium. Treatments of a drop of HMP suspension (1 µl or 0.1 µl) or of water (Control) were added to the medium. Long-term series of trials, with two different HMPs, were conducted over 18 and 9 months with 76 and 38 trials, respectively. In the first series, the effect of a 1 µl drop of HMP suspension on root growth was significant overall (−2.4%, p = 0.004, Tukey-Kramer-test) and in 35.5% of the individual trials (p < 0.05). However, the effects fluctuated strongly between the trials (from −25.7% to +19.1%). The effect of a 0.1 µl drop was similar, but lower in magnitude. The results of the second series were analogous. Comparison of statistical models provided significant evidence of a growth-stabilising effect. An additional series of 22 negative control trials indicated an acceptable false positive rate. It was concluded that HMP, at low doses, significantly influenced root growth at early stages, with a stabilising pattern of action. Further development of the bioassay should improve its power and stability over time. A stabilising effect may induce an increased resilience of the agricultural system.","PeriodicalId":8904,"journal":{"name":"Biological Agriculture & Horticulture","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2020-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/01448765.2019.1644668","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47811096","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a second factor, VC was applied at three different rates of application (3, 6 and 9 t ha−1 for R and B, and 2, 4 and 6 t ha−1 for U). In both years, the different rates and placement methods had no significant effect on the fresh yield of tomatoes. However, in 2015, the treatment with the higher rate and the U placement of the VC increased the dry matter (DM) yield of the plants by up to 48% (8.4 t ha−1). Evidently, treatments with the U method had 23 % higher nitrogen (N) uptake (156 kg ha−1) compared with the treatments where VC was broadcast in the field (121 kg ha−1).

David Hodges was born in 1934 and spent his early childhood years in places close to London and then in Devon, England. Hodges studied Zoology at Exeter University, where he met his wife Ursula (nee Rumley). After graduating in 1957, Hodges moved to London to undertake research for a PhD at the Institute of Urology of London. Just at the point of submitting his thesis in 1960 Hodges was drafted in for national service at the Royal Army Medical Corps, hence the completion of his PhD had to be delayed until 1962. According to Hodges himself, one of the most valuable things he learnt from his time with the army was the futility of war and he became a pacifist not long afterwards (Hodges 1988). Ursula and David Hodges were married in 1958, and in 1962, after Hodges’ national service, they moved to Ashford in Kent, England, where he took up a lecturing post at Wye College, the School of Agriculture of the University of London. Hodges’ role at Wye College was initially intended to be mainly associated with research into the physiology of laying hens and he spent a number of years investigating calcium metabolism and digestive function in battery hens. Hodges’ research experience in intensive poultry production opened his eyes to what was happening in industrial food production, and this, together with reading Rachel Carson’s Silent Spring, soon began to change his whole outlook. Hodges was convinced that the industrial approach to agriculture was morally wrong and that in practice it would create more problems than it would solve (Conford 2011a, 2011b). He developed a strong interest in all matters related to organic agriculture and, although his work at Wye College was mainly teaching and to undertake research in the field of animal physiology, being in a School of Agriculture gave him the necessary justification to become involved in the wider aspects of organic farming. In the years that followed, Hodges came to have a very a prominent role in the organic agriculture movement in Britain. Indeed, with his specific interest in the scientific exploration of organic agriculture and pursuit for developing the scientific case for organic farming, the remarkable work of Dr David Hodges was the subject of an agricultural history paper written by Conford (2011a). Hodges acknowledged that, academically, his work in organic farming had not always been an easy task and it had often been an uphill struggle to convince those with whom he worked that the organic option was something worth looking into.

The ASCs (Poaceae, i.e. rye, barley, wheat, spelt and their mixture), were characterised in terms of aboveground biomass, N uptake, C : N ratio and degradation rate. During the melon growth cycle, soil mineral N (SMN), weed density and biomass were measured and the design of trial included weeded and unweeded plots. The yield and concentrations of soluble solids of the melon was measured. The ASC mulches differed in their N supply capacity and degradation rate. Rye and spelt were the best in terms of weed control, with approximately 80% lower weed density and weed biomass for either rye or spelt compared with the control. Wheat was the least effective against weeds, but it enhanced SMN. Melon yields were similar in plots with spelt and rye, weeded and unweeded treatments, but were reduced in the unweeded control (−58.5%) and barley treatment (−41.2%), compared with the respective weeded treatments. The low melon yield in the plots with rye suggested a negative allelopathic rye-melon interaction.
