Efecto de tres densidades de siembra y dos tipos de fertilización, en el crecimiento y el rendimiento en el cultivo de maní (Arachis hypogaea L. var. INIAP-380) en Zapotepamba, provincia de Loja

This research work was carried out at the Binational Technical Training Center Zapotepamba, Canton Paltas, Loja province, with the objective of studying the effect of three planting densities and two types of fertilization (chemical and organic), as well as the profitability of each treatment. A completely randomized block design (CSBD) was used with six treatments and four replications, with a total of 24 experimental units. The treatments were as follows: T1= Density 40*40 cm + Nutrisano Organic Fertilization; T2= Density 50*40 cm + Nutrisano Organic Fertilization; T3= Density 40*30 cm + Nutrisano Organic Fertilization; T4= Density 40*40 cm + 12-8-16 + Folizyme+Urea (46 % N); T5= Density 50*40 cm +12-8-16 +Folizyme+ Urea (46 % N); T6= Density 40*30 cm + 12-8-16 +Folizyme+ Urea (46 % N). The variables to be evaluated consisted of peanut crop phenology, growth variables and yield parameters. For the statistical analysis of data, the Insfotat software was used using analysis of variance (ANOVA), to evaluate the statistical differences, the Tukey test at 95 % was used, a Pearson correlation at 95 % between the variables and the benefit-cost ratio was calculated. The treatments did not significantly affect the duration time of the phenological phase, in the same way in variables of number of nodules, number of branches, aerial dry biomass, root dry biomass, weight of 100 pods with seed, weight of 100 seeds, number of pods/plant, pod/seed equatorial diameter. While the treatments that did show significant differences were the application of T4= Density 40*40 cm + 12-8-16 +Folizyme + Urea (46 % N) in the variables of plant height (35 cm) and stem diameter (7,78 cm) obtained higher values in relation to the other treatments. In the same way, there were significant differences with the application of treatment T3= Density 40*30 cm + Nutrisane organic fertilization; in the pod length variable (4,03 cm). There were significant differences in peanut yield, with T6= Density 40*30 cm + 12-8-16 + Folizyme +Urea (46 % N) obtaining the highest average with 2, 34 t/ha, while the lowest was for T5= Density 50*40 cm +12-8-16 + Flizyme +Urea (46 % N); with 1.69 t/ha. In the benefit-cost ratio, with the treatment T6= Density 40*30 cm + 12-8-16 + Urea (46 % N) a value of 1,29 was obtained, which indicates that values greater than 1 mean that the income is greater than the costs, so the project is profitable, while in the other treatments values less than 1 were obtained.
