Yield of “Pipiana” squash (Cucurbita argyrosperma Huber) in Vertisol soil due to the effect of biostimulants

Abstract

Objective: Evaluate the effect of liquid (supermagro) and solid (bocashi) biostimulants on the yield of pumpkin (Cucurbita argyrosperma Huber) in a Vertisol soil.

Design/methodology/approach: The research was carried out May-August of 2018 in the “Central Flores” ranch, the treatments were: T1 = control, T2 = 400 g of bocashi + supermagro 1:20 v / v, T3 = 400 g of bocashi + supermagro 1:30 v / v, T4 = 500 g of bocashi + supermagro 1:20 v / v, T5 = 500 g of bocashi + supermagro 1:30 v / v, with four replicas (plots) of each. For the statistical analysis, agronomic data of 11 variables were registred in 10 plants per plot and 12 variables in seed, the experimental design used was completely random. An ANOVA and a means comparison test (Tukey, ??0.05) were performed with the Statistical Analysis System version 9.1 (SAS, 2003).

Results: The treatmen 4 presented the highest values in the majority of the variables evaluated, the yield of fresh fruit and dried seed is 4.48 t ha^-1 and 1.76 t ha^-1, respectively, results superior to those reported in the scientific literatura.

Limitations/implications: No limitations were found in the present study.

Findings/conclusions: The application of the foliar and edaphic bistimulant increases the quantity and quality of the fruit and seed Cucurbita argyrosperma Huber.
