RESUMEN
A field trial was conducted during Rabi 2020-21 in randomized block design with three replications and seven treatments comprising individual and combined application of various organic and inorganic nutrient sources at Research Farm, MMU Sadopur (Ambala), Haryana. The experiment was intended to evaluate the effect of vermicompost, biofertilizers and inorganic fertilizers applied in chickpea on nutrient uptake and physico-chemical properties of soil pH (8.24). The highest organic carbon (0.58%), electrical conductivity (0.51 dS m-1), particle density (2.50 g/cm3) and porosity (48.47%) along with maximum available N (126.5 kg ha-1), P (23.2 kg/ha) and K (98.33 kg/ha) were observed in the treatment of T6 i.e., 3 t/ha Vermicompost + Rhizobium + PSB. Similarly, the nutrient content (N, P and K) was maximum in seed and stover of chickpea harvested from the plots receiving 3 t/ha Vermicompost + Rhizobium + PSB, which was statistically at par with T7 i.e., 2.5 t/ha Vermicompost + Rhizobium + PSB. The highest net return was recorded in plots treated with 50% RDF (Recommended dose of fertilizer) + Rhizobium + PSB and 75% RDF + Rhizobium + PSB with a benefit cost ratio (B: C) of 3.2 and 3.1, respectively. However, the seed yield in integrated nutrient management was comparable to recommended dose of chemical fertilizers

RESUMEN
Coleus forskohlii L. is an important medicinal plant species found in tropical regions of India. Roots and tubers are used for treating a variety of purposes, including treating asthma, bronchitis, insomnia, epilepsy and angina.Due to diverse use, the species has been largely exploited from natural habitat leading to its threatened status. A field experiment was conducted to study the influence of organic and inorganic fertilizers on its growth and yield. Six treatments including T1 Control -No Manures; T2: 100% NPK recommended dose (N- 40 kg ha-1), T3: 50% NPK + 10 Tonnes of Farm Yard Manure / ha-1, T4: 50% NPK + 5 Tonnes of Vermicompost/ ha, T5:20 Tonnes of Farm Yard Manure / ha and T6: Vermicompost 10 Tonnes/ha-1. Results indicated the improvement in the growth and yield. Combination of organic and inorganic fertilizers is very productive than the application of manures or fertilizers alone for achieving higher growth and yield in C.forskohli.
RESUMEN
Phytoremediation is an ecologically sound biotechnology directed to cleaning up contaminated soils. The study of tree species to treat petroleum contaminated soils is scarce; moreover, the combination of phytoremediation with bioaugmentation and biostimulation processes is also limited. Thus, this work evaluated the effects of the inoculation of Glomus intraradices, a bacterial consortium (M2BOS1-R2 and M2BOSI-F4) and Trichoderma viride, on the growth of Casuarina equisetifolia, fertilized with Floranid® or Triple 17, when sown in a diesel-contaminated soil (7 500mg/kg). The factorial experiment 2x5x3 included 30 treatments with 10 replicates in a completely randomized design under greenhouse conditions for 120 days. Diesel significantly diminished plant height, total biomass, and plant index quality (PIQ). Glomus or bacterial consortium significantly increased plant height, total biomass and PIQ when compared to the inoculation of the three microorganisms or to the control. Floranid had negative effects on plant growth and PIQ at diesel contamination. Fertilization with Triple 17 combined with the three microorganisms stimulated plant growth in the absence of diesel, whereas in the presence of this contaminant the treatments combining Triple 17 with the bacterial consortium or with Trichoderma had better plant growth and PIQ. Mycorrhizal colonization was inhibited due to diesel contamination, and especially when Floranid was applied. The fertilizer Triple 17 (biostimulation) combined with the beneficial microorganisms (bioaugmentation) improved growth responses of C. equisetifolia in diesel-contaminated soil.
La fitorremediación es una biotecnología ecológicamente racional que está dirigida a la limpieza de suelos contaminados; sin embargo, el estudio de especies arbóreas para la fitorremediación de suelos con hidrocarburos del petróleo es limitado. Más aún, la combinación de la fitorremediación con procesos de bioaumentación y bioestimulación es también limitada. Por lo anterior, este estudio evaluó el efecto de la inoculación de Glomus intraradices, un consorcio bacteriano (M2BOS1-R2 y M2BOSI-F4) y Trichoderma viride en el crecimiento de plantas de Casuarina equisetifolia L. fertilizadas con Floranid® o Triple 17, en suelo contaminado con diésel (7 500mg/kg). El experimento factorial 2x5x3 incluyó 30 tratamientos y 10 repeticiones, distribuidos completamente al azar en invernadero, durante 120 días. El diésel disminuyó significativamente la altura, la biomasa total y el índice de calidad (ICP) de planta. Glomus o las bacterias aumentaron significativamente la altura, la biomasa seca total y el ICP con respecto al tratamiento sin inocular o con la triple inoculación. El Floranid redujo el crecimiento vegetal y el ICP, en presencia de diésel. El Triple 17 combinado con los tres microorganismos produjo mayor crecimiento vegetal en ausencia de contaminación, pero en presencia de diésel, el Triple 17 combinado con bacterias o con Trichoderma, estimuló la biomasa seca total y el ICP. La colonización micorrízica fue inhibida por el diesel, especialmente con la fertilización del Floranid. El Triple 17 (bioestimulación) combinado con los microorganismos (bioaumentación), favoreció el crecimiento de Casuarina en suelo contaminado con diésel.
