En el Perú, el mango variedad Kent, es la fruta de mayor exportación e interés socioeconómico para el país, producida tradicionalmente bajo una fertilización convencional; sin embargo, su productividad se ve afectada debido al incremento de los costos de producción principalmente de los fertilizantes. Objetivo: Evaluar el efecto de la aplicación de compost y biol en las variables productivas del cultivo de mango var. Kent. Metodología: Se evaluaron los tratamientos T0: testigo; T1: compost 5 t ha-1 ; T2: compost 15 t ha-1 ; T3: biol 5%; T4: biol 10%; T5: compost 5 t ha-1 + biol 5%; T6: compost 5 t ha-1 + biol 10%; T7: compost 15 t ha-1 + biol 5% y T8: compost 15 t ha-1 + biol10%. Las variables evaluadas fueron: diámetro polar del fruto (DPF-mm), diámetro ecuatorial del fruto (DEF-mm), diámetro diagonal del fruto (DDF-mm), tasa de crecimiento promedio por día (TCPD-mm día-1 ...

El presente estudio se realizó en la parcela del señor Luis Raúl Córdova Córdova, ubicada en el caserío Las Mónicas, distrito de Tambogrande, provincia de Piura, entre el mes de septiembre de 2022 y marzo de 2023. El objetivo fue evaluar el efecto de la aplicación de compost y biol en el rendimiento y calidad del cultivo de mango (Mangifera indica L.) variedad Kent. Se evaluaron 9 tratamientos; T1(Compost 5 t ha-1), T2(Compost 15 t ha- 1), T3 (Biol 5 %), T4 (Biol 10 %), T5 (Compost 5 t ha-1 + Biol 5%), T6(Compost 5 t ha-1 + Biol 10 %), T7(compost 15 t ha-1 + Biol 5 %), T8 (Compost 15 t ha-1 + Biol 10 %) y un testigo, distribuidos en un diseño de bloques completamente al azar. Los parámetros de rendimiento evaluados fueron: Número de frutos cosechados por panícula, peso del fruto, diámetro ecuatorial del fruto, diámetro polar del fruto, diámetro diagonal del fruto, rendimie...

Potato (Solanum tuberosum L.) is the third most important food crop worldwide and a cornerstone of food security across the Andean region. However, its production is increasingly threatened by the potato psyllid Bactericera cockerelli (Šulc), the vector of Candidatus Liberibacter solanacearum, the causal agent of the purple-top complex associated with zebra chip disease, which severely reduces both tuber yield and quality. This study was conducted from September 2024 to February 2025 in the province of Huancabamba, Peru, to evaluate the efficacy of biological and chemical control agents against B. cockerelli under field conditions. A randomized complete block design was implemented with five treatments and four replicates, totaling 20 experimental units, each consisting of 20 potato plants (S. tuberosum L.), of which 10 plants were evaluated. Treatments included an untreated control (T0...

Background: Cotton is a crop of great socioeconomic interest in the textile industry in Peru, however, it is sown directly in the field where it presents irregular germination. Objective: To evaluate the effect of four doses of hydrogen peroxide and two imbibition times on the germination and initial growth of cotton. Methodology: The commercial hydrogen peroxide CP (H2O2 at a concentration of 3 g 100 mL¯¹) was used in the treatments: T0 (control- distilled water), T1 (10% CP), T2 (30% CP), T3 (50% CP), T4 (100% CP) subjected to 6 and 12 h of imbibition. Germination evaluations were made: germination percentage (GP), germination speed (GS), germination index (GI), Biometry: seed weight (SW), stem length (ST), number of leaves (NL) and root length (RL). Stem biomass: fresh weight (SFW) and dry weight (SDW), and root biomass: fresh weight (RFW) and dry weight (RDW). Results: T3-6 h impro...

Mango (Mangifera indica L.) is a tropical fruit tree characterized by vigorous growth and high fruit production, making it one of Peru's main export crops. However, its extensive vegetative development requires substantial space, limiting productivity per unit area. This study evaluated the effects of rootstock and interstock combinations on agronomic traits and fruit biometrics, highlighting the potential of interstocks to modulate tree vigor in mango orchards of Peru's dry forest region. A total of 216 trees were established using 'Chulucanas' and 'Chato' as rootstocks and 'Chulucanas,' 'Chato,' 'Irwin,' and 'Julie' as interstocks, apically grafted with the 'Kent' cultivar, with a spacing of 6.0 m × 6.0 m. Tree performance was assessed after 10 years during the 2017–2019 growing seasons in Piura, Peru, under a randomized complete block design (2 × 4 factorial). The combination of t...
