The experiment was conducted in one of the private fields in Diyala governorate. Cultivation was carried out in Autumn on September 15, 2013, and the harvest of tubers was on 25 December 2013. Reverie Elite class was used. A factorial experiment was carried out in Randomized Complete Block Design using two factors in three replicates. The differences between the averages were tested according to the L.S.D test at the level of probability 0.05. The first factor was mulching M included two treatments M1: mulching by wheat straw and M2: mulching by black plastic, the second factor F fertilization included four levels; F0 control without addition, F1 Chemical fertilizers as recommended (200, 240 and 600 kg/ ha for K2SO4, P2O5 and urea respectively), F2: fertilized by sheep compost at 5% and F3 spraying of amino acid proline with a concentration of 200 ppm. The results of the study showed that the treatment of black plastic (M2) is superior in the percentage of field maturity (100.00%), the number of plant stems (4.26), plant height (62.84 cm), the weight of the tuber (143.60 g) and plant yield (961.75), but The total number of tubers was not significantly different from wheat straw mulching. While fertilization treatments, proline (F3)was significantly increased number of stems (4.87), plant height (65.16) cm, tubers weight (159.80), plant yield (1158.16) g and the total yield (46.33) t ha-1. The germination rate did not differ significantly between the treatments. The interaction between fertilization with sheep compost and black plastic mulching with proline (M2F3) showed significant increasing in plant height (70.77) cm, number of tubers (7.60) weight of tuber (164.58) g, plant yield (1251.81 g) and total yield (m) 50.07 tons ha-1 except for germination ratio

Nitrate Concentrations

Thirteen field trials were conducted on ferrosols and tenosols in Tasmania to assess the response of potatoes (Solanum tuberosum L., cv. Russet Burbank) to basal and topdressed nitrogen fertiliser. The objectives of this study were to assess whether petiole nitrate concentrations could be used to indicate potato nitrogen status and crop response to nitrogen topdressing, and whether various soil nitrogen measures could be used to determine the responsiveness of potatoes to nitrogen fertilisation. Petiole nitrate-nitrogen concentrations in the youngest fully expanded leaves were found to be an indicator of nitrogen status. Critical nitrate concentrations varied in a linear fashion from about 25 000 mg/kg at tuber initiation to less than 5000 mg/kg when tubers were 100 mm long (about 100 days after planting). These concentrations are consistent with those determined for Russet Burbank in other studies. In contrast to petiole measures, various pre-plant and early season soil nitrogen measures (mineral, mineralisable and total nitrogen) did not adequately (adjusted R2<0.25) explain variation in crop nitrogen responsiveness and could not be recommended as diagnostic or predictive tests. Soil nitrogen mineralisation rates in spring varied from 0.4 to 5 kg N/ha.day and were higher at sites previously in pasture than at continuously cropped sites. Although petiole nitrate concentrations responded to nitrogen topdressing, most nitrogen-deficient crops in this study did not show yield responses to topdressed nitrogen. This limited the usefulness of petiole nitrate-nitrogen tests.

Objetivo: Establecer una línea base como fundamento para la intervención e inducción de innovaciones a través de escuelas de campo y planes de negocios. Diseño/metodología/aproximación: El estudio se desarrolló en San José del Carmen, San Cristóbal de Las Casas, Chiapas, México. Se elaboró una encuesta como instrumento para recabar en campo información de familias de la localidad con la finalidad de conocer su situación actual. La localidad de trabajo se eligió utilizando como criterio las poblaciones que se encuentran dentro de Cruzada Nacional contra el hambre y en la clasificación de la pobreza extrema Resultados: La localidad de San José del Carmen es considerada como de alta marginación, la población es bilingüe, su principal lengua es el Tzotzil, el nivel de estudios promedio es hasta el tercer año de primaria, las principales actividades productivas son la siembra de maíz (Zea mays L.), frijol (Phaseolus vulgaris L.), papa (Solanum tuberosum L.) y haba (Vicia faba L.) que son utilizadas principalmente para autoconsumo.  No cuentan con agua potable ya que su sistema es a través de la recaudación de agua de lluvia o a través de un jagüey. Sus principales actividades económicas son la albañilería por parte de los hombres, y venta de productos, tales como el pozol (bebida energética a base de maíz y cacao (Theobroma cacao L.), tostadas y algunos vegetales por parte de las mujeres. Las tostadas son producidas en forma artesanal con un proceso de doble nixtamalización y vendida en bolsas de 20 tostadas cada una, a un costo de MX$10.00 en los mercados de San Cristóbal de las Casas, una a dos veces por semana alrededor de 40 bolsas por día de venta. Limitaciones del estudio/implicaciones: La afiliación zapatista de alguno de los pobladores y el hecho de que algunos habitantes no hablen español, fueron factores que limitaron desarrollar al 100% el estudio; sin embargo, se considera que se tienen los elementos necesarios para establecer la línea base de la situación de San José del Carmen. Conclusiones: El diagnóstico servirá como una herramienta para establecer una intervención a través de innovaciones y planes de negocios en la comunidad de estudio. Los pobladores cuentan con herramientas necesarias para obtener nuevos conocimientos que ayuden a un desarrollo de su producción. El idioma no deberá de ser una limitante para ello.

Kebutuhan kentang yang semakin tinggi menyebabkan permintaan semakin meningkat. Rendahnya produksi kentang mengakibatkan berbagai upaya untuk peningkatan produksi terus dilakukan. Penggunaan metode kultur jaringan yaitu metode untuk mengisolasi bagian tanaman seperti protoplasma, sel, sekelompok sel, jaringan dan organ dalam kondisi aseptik, sehingga dapat diperbanyak dan beregenerasi menjadi tanaman utuh dapat dijadikan alternatif pemenuhan kebutuhan. Penelitian ini bertujuan untuk mengetahui kecepatan pembentukan umbi mikro kentang (Solanum Tuberosum L.) varietas granola kembang secarain vitro dengan menggunakan dua faktor dan 3 kali ulangan. Faktor pertama yaitu aspirin dengan tiga taraf (5,10,15) ppm. Faktor kedua yaitu kinetin dalam tiga taraf (8,10,12) ppm. Penelitian menggunakan seluruh propagul kentang yang berumur 30 hari setelah subkultur dan data yang didapat dianalisis menggunakan ANOVA. Hasil penelitian menunjukan bahwa interaksi aspirin dan kinetin tidak berpengaruh terhadap jumlah akar, kedinian umbi, dan bobot umbi. Interaksi perlakuan terbaik bagi pembentukan tunas yaitu A2K1 aspirin 10 ppm dan kinetin 8 ppm sedangkan Interaksi perlakuan terbaik pada parameter jumlah umbi yaituA3K2 aspirin 15 ppm dan kinetin 10.

Clavibacter Michiganensis

В статье обсуждается влияние на проращивание клубней монойодацетата натрия (МИА) совместно с прогреванием (45 °C, 1 ч) в качестве потенциального агента для борьбы с Clavibacter michiganensis ssp. sepedonicus (Cms) перед закладкой картофеля на хранение. В работе использованы клубни картофеля (Solanum tuberosum L.) сорта Лукьяновский. В эксперименте присутствовало четыре варианта обработки клубней, в каждом варианте было 30 клубней. После проведенных обработок клубни помещали в условия овощехранилища на 8 месяцев. Весной подсчитывали количество ростков, измеряли длину проростков у клубней и проводили клубневой анализ. Полученные результаты статистически обрабатывали с использованием пакета программ Excel. Показано, что заражение клубней Cms снижало способность клубней к прорастанию. Обработка МИА и прогревание здоровых клубней картофеля перед закладкой на хранение подавляло прорастание клубней, что полезно для продовольственного картофеля. Результаты клубневого анализа показали, что прогревание снижало общее количество больных клубней примерно на 39 %, клубни были менее поражены кольцевой и бурой гнилями. Обработка МИА также способствовала снижению количества клубней, пораженных бурой и кольцевой гнилями. Обработка клубней МИА совместно с прогреванием снижала общее количество больных клубней, пораженных проволочником и пустотелых, кольцевой и сухой гнилями, а также паршой. Обработка МИА и прогреванием инфицированных клубней картофеля перед закладкой на хранение снимала подавляющий эффект бактерий на прорастание. Полученный результат актуален для обработки семенного картофеля, так как кольцевая гниль является латентным заболеванием.
