A field experiment was conducted at Agronomy research farm, S.K.N. College of Agriculture, Jobner during kharif, 2015 in order to evaluate the performance of groundnut (Arachis hypogaea L.) under varying levels of sulphur and its sources. Results of experiment revealed that CGR of crop during 0 - 35 DAS registered significant increase upto application of sulphur at 45 kg/ha. However, at later stages of growth the significant increase was noted upto 60 kg S/ha only. Application of sulphur at 60 kg/ha recorded a significant increase of 6.1 per cent in RGR over 15 kg/ha during 70 DAS – at harvest stage. Likewise, application of 60 kg S/ha also significantly enhanced the number of total and effective nodules as well as fresh and dry weight of nodules/plant and produced significantly higher pod and biological yields of groundnut (1832 and 5361 kg/ha) than 45, 30 and 15 kg/ha. Application of sulphur through gypsum recorded significant increase in plant height and dry matter accumulation/m row length at all the stages of crop over SSP and elemental sulphur treatments. The maximum CGR at all the stages of crop was recorded when sulphur was applied through gypsum. Sulphur application through SSP registered 13.9, 9.8 and 21.4 per cent increase in CGR over elemental sulphur at these stages, respectively. On the other hand, SSP and gypsum increased the RGR by 7.2 and 6.3 per cent, respectively over elemental sulphur. Gypsum as a sources of sulphur fertilization recorded the highest number of 62.30 total and 55.00 effective nodules/plant and as well as fresh and dry weight of nodules (229.87 and 102.00 mg/plant) thereby increasing to the extent of 22.1, 27.6, 23.9 and 18.9 per cent over elemental sulphur. Sulphur application through gypsum produced 13.1 and 10.2 per cent higher pod and biological yield of groundnut over elemental sulphur.

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>
