An experiment was conducted during kharif season of 2016 and 2017 at College of Agriculture, Gwalior. To optimise plant population and fertility levels an experiment was laid out in split plot design, replicated thrice in fixed plots and the test variety of the crop groundnut (Mallika) was used. The plant geometry of 30 × 10 cm, 25 × 10 cm and 20 × 10 cm was adopted with three fertility levels as 75, 100 and 125% recommended dose of fertilizers. The yield and economics were increased by optimization of plant geometry and nutrient management under kharif groundnut. Sowing of crop at 30×10 cm spacing resulted in 7.3 and 4.3 % higher pod yield over 25×10 cm and 20×10 cm spacing, respectively and 3.0 % higher haulm yield over 25×10 cm. Similarly, application of 125% RDF resulted in 3.0 and 9.3 % higher pod yield over 100% RDF and 75% RDF, respectively but application of 100% RDF resulted in 18.6% higher haulm yield over 75% RDF and was at par with 125 % RDF application. The highest gross, net returns and B:C ratio was obtained at the spacing of 30×10 cm with 125% RDF.

A field experiment was conducted to study the effect of integrated nutrient management on productivity, quality and nutrient uptake in summer groundnut (Arachis hypogaea L.) during summer 2018 at Dantiwada, Gujarat. The treatment consisted of ten different integrated nutrient management treatments practices. The integration of inorganic fertilizers along with seed inoculation of biofertilizers viz., Rhizobium and phosphates solubilising bacteria (PSB) recorded significantly higher pod and haulm yield of summer groundnut as compared to rest of the treatments. Combined application of 75 % recommended dose of nitrogen (RDN) and 25 % RDN through vermicompost or farm yard manure (FYM) along with seed inoculation of Rhizobium and phosphates solubilising bacteria (PSB) recorded higher pod and haulm yield and also higher net returns and B- C ratio in summer groundnut.

Background: Irrigation and proper nutrient management that determines the productivity of the groundnut especially during the critical stages of the crop growth. Methods: The experiments laid out in split plot design comprising of three levels of irrigation scheduling [0.8 IW/CPE ratio (I1), 0.6 IW/CPE ratio (I2) and 0.4 IW/CPE ratio (I3)] in main plots and four nutrient management practices viz., N1- 75% of RDF with 5 t of charred rice husk, N2 - 50% of RDF with 5 t of charred rice husk, N3 - 75% of RDF with 5 t of charred rice husk along with seed treatment of Abuscular mycorrhiza and N4 - 50% of RDF with 5 t of charred rice husk along with seed treatment Arbuscular mycorrhiza in sub plots and replicated thrice. Result: Highest pod yield (2003, 2099 and 2063 kg ha-1 during summer, kharif and rabi 2017, respectively) of groundnut was registered with irrigation scheduling at 0.8 IW/CPE ratio along with 75% of RDF and 5 t of charred rice husk as basal with seed treatment of Arbuscular mycorrhiza. The maximum water use efficiency was also recorded under of the same treatment (4.16, 7.07 and 4.86 kg ha-1 mm-1 during the various seasons respectively). The highest B:C ratio of 2.2, 2.4 and 2.2 was recorded during summer, kharif and rabi 2017, respectively were also registered with same combination irrigation and nutrient management.

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.
