Field Strengths

Present work is about the influence of Electromagnetic field [EMF] treatment on the improvement of groundnut seeds (Arachis hypogaea L) germination. The treatment consisted of different electromagnetic field strengths 2, 4, 7 and 10 milli Tesla [mT] in different exposure times 10, 20, 30 and 40 min. In every measurement, the relative humidity and room temperature were recorded. The germination [G] of seed in terms of percentage [% ], the stems length [SL] and roots length [RL] in millimeter [mm] at 6th day and 12th day after experiment, and the total weight [TW] in milligram at 12th day have been measured. Best results have been obtained for variants with exposure time of 30 min and field strength of 7 mT at south pole. Result obtained in the present investigation revealed that the energy absorbed by molecules was high at lower output strength and shorter exposure time improved biologicalfunctions, stimulation effect could be achieved.

Field Emergence

Abstract Late-maturing peanut cultivars including DP-1, C-99R, Hull, Georgia-01R, and Florida MDR-98 (Arachis hypogaea L.) have improved resistance to late leaf spot, white mold, and tomato spotted wilt virus. The improved disease resistances offer potential cost savings for farmers. However, poor field emergence resulted in unacceptable plant stands and caused commercial seed companies to stop producing Florida MDR-98, DP-1, and Hull even though germination tests usually showed acceptable germination. Reduced field emergence seldom occurs when seed of these cultivars is grown, harvested, and stored in small batches in research storage facilities. To determine the effect of storage environment, pods of four cultivars were stored in four environments and the seeds were subjected to standard germination tests and immediately followed by field emergence evaluations. Cultivar affected both field emergence and germination. Storage environment affected field emergence, and to a lesser extent, germination (P = 0.0847). Peanut pods stored in a traditional peanut warehouse experienced elevated temperature and relative humidity compared to seeds stored in climate controlled facilities and those seed had reduced field emergence. There was a cultivar by storage environment interaction. Field emergence was maintained when seed was stored where temperature was below 16 C and relative humidity (RH) was less than 70%. This work suggests that seed vigor of the cultivars like DP-1 and Hull deteriorates faster than that of other cultivars when stored in commercial warehouses even though germination tests indicate that the seed should produce satisfactory plant stands.

Objetivo: Evaluar la germinación de cacahuate (Arachis hypogaea L.) mediante el uso de diferentes dosis de ácido giberélico (GA3). Diseño/metodología/aproximación: Se empleó un diseño completamente al azar. Se utilizaron tres tratamientos con 20 repeticiones. Tratamiento 1: 0.05gr/L de ácido giberélico (GA3), Tratamiento 2: 0.10gr/L de ácido giberélico (GA3), Tratamiento 3: 0.15gr/L de ácido giberélico (GA3) y Tratamiento 0: Testigo. Se utilizaron semillas de cacahuate de la variedad Virginia. Los parámetros a evaluar fueron, la altura de plántula, número de hojas, medida de raíz y biomasa.  Las medias fueron comparadas por la prueba de Tukey a un nivel del 5% de confianza. Resultados: Los tratamientos indicaron que el Tratamiento 0 (Testigo) obtuvo un porcentaje de germinación de 85%, siendo mayor que el tratamiento 3 (0.15gr/L de GA3) con un 75% de germinación, sin embargo, el tratamiento 1 (0.05gr/L de GA3) y 2 (0.10gr/L de GA3) presentaron una mejor respuesta al obtener un 95% de germinación cada uno. Limitaciones del estudio/implicaciones: El tratamiento 3 causa efectos negativos en la germinación de la planta. Hallazgos/conclusiones: Es necesario dar seguimiento a la investigación para un mejor control del ambiente y ampliar las dosis de GA3, así como aumentar la velocidad de germinación aplicando 0.15gr/L de GA3.

<p><em>Penelitian ini bertujuan untuk mempelajari pengaruh sistem tanam alur dan pemberian jenis pupuk terhadap pertumbuhan dan produksi kacang tanah (Arachis hypogaea L.). Penelitian dilaksanakan di KP Leuwikopo IPB Dramaga, Bogor pada bulan Februari - Juni 2013. Percobaan menggunakan rancangan petak terbagi (Split Plot Design) dengan perlakuan terdiri dari dua faktor, yaitu sistem tanam alur sebagai petak utama dan jenis pupuk sebagai anak petak. Hasil penelitian menunjukkan bahwa perlakuan sistem tanam alur meningkatkan daya hasil pada produktivitas biji kering, produktivitas polong kering, dan bobot kering biji per tanaman lebih baik dibandingkan sistem tanam konvensional. Hal tersebut ditunjukkan dengan perlakuan sistem tanam alur yang memiliki produktivitas 2.93 ton/ha polong kering, sedangkan sistem tanam konvensional sebesar 2.55 ton/ha polong kering. Sistem budidaya kacang tanah pada sistem tanam alur dapat meningkatkan efisiensi tanaman dalam memanfaatkan unsur hara yang telah diberikan baik pupuk organik maupun anorganik, sehingga pertumbuhan dan hasil tanaman kacang tanah menjadi lebih baik. Pemberian jenis pupuk kandang ayam + Dolomit + NPK memberikan respon terhadap pertumbuhan dan  daya hasil rata-rata tanaman yang lebih baik dibandingkan jenis pupuk lainnya.</em></p>
