The aim of the study was to assess genotypical differences over different stages for morphophysiological parameters associated with iron (Fe) deficiency and their effect on yield. The factorial pot experiment was comprised of two major factors, i) soil-Fe status of natural vertisol [Fe-sufficient and Fe-deficient soils], and ii) genotypes [CP-3443, CP- 4105, CP-3486 and CP-4069] with differential iron-induced deficiency chlorosis (IDC) response. Data were recorded and associations between different traits were estimated. Under Fe-deficient soil, tolerant genotype (CP-3443) recorded significantly higher chlorophyll content, peroxidase activity in leaves, and better yield compared to susceptible genotypes which verified usefulness as IDC tolerant potato genotypes characteristics.

Two field experiments were conducted to investigate the effects of three drip irrigation regimes (G1: 120% crop evapotranspiration (ETc), G2: 100% ETc, and G3: 80% ETc) and four nitrogen (N) source treatments (S0: non-fertilized; S1: urea, S2: ammonium nitrate, and S3: ammonium sulfate on water consumption use, water utilization efficiency, chlorophyll, yield and tubers quality of potato (Solanum tuberosum L.; cv Diamond) under a drip irrigation system during two successive winter seasons (2015/16 and 2016/17)). Nitrogen fertilization was applied at 380 kg ha−1 as standard application for potato in the investigated area. The highest tubers yield was obtained from potato grown with G1 S2 (65.8 Mg ha−1), G1 S3 (63.6 Mg ha−1), G2 S2 (64.1 Mg ha−1), and G2 S3 (62.4 Mg ha−1), while the lowest tubers yield was obtained from potato grown with G3 S0 (10.1 Mg ha−1) and G2S0 (17.4 Mg ha−1). Different treatments of N source resulted in a significant increase for water use efficiency (WUtE) compared with unfertilized treatment. For the interaction effect, the highest WUtE was obtained from potato grown with G3 S2 (18.1 kg m−3), followed by G3 S3 (17.6 kg m−3), while the lowest WUtE was obtained from plants grown with G3S0 (3.0 kg m−3). However, the highest chlorophyll content was obtained from plants grown with G1 and any N source, followed by G2S1-3, while the lowest chlorophyll content was obtained from those grown with G3S0. The highest N, S, protein, and P contents in tubers were obtained from plants grown with G3S3, G3S2, and G2S2, while the highest K content in tubers was obtained from plants grown with G1S1 and G1S2. In concussion, the integrative effects of G1 or G2 with S2 or S3 is recommended for high productivity, while the integrative effects of G3S3 and G3S2 are recommended for high quality tubers.

Effect On Yield

Potatoes (Solanum tuberosum L. ’Kennebec’) receiving similar N, P and K nutrition showed no consistent changes in yield, specific gravity and quality of boiled tubers when K2SO4 and KNO3 were substituted for the commonly-used KCl. Broadcasting three-quarters of the K as KCl the previous fall, compared with banding at planting, had no effect on yield or quality.

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.
