Abstract
The research deals with phosphorus fertilization to obtain higher yields in garlic cultivation. The objective was to determine the appropriate dose of foliar phosphorus fertilization, to obtain a higher yield in garlic cultivation. The methodology is based on applied and experimental research; Therefore, the Completely Random Block Design was used, composed of 4 blocks and 5 treatments which were T1 = 00, T2 = 250, T3 = 500, T4 = 750, T5 = 1000 mL of phosphorus (Wuxal phosphorus)/200 L. water and were applied 15, 30 and 45 days after sowing. They were evaluated from sowing to postharvest and the data were processed with analysis of variance and Duncan. Likewise, phosphorus concentrations in leaves were analyzed. The results determined that T4 stood out in stem length with 35.28 cm, commercial yield with 11.208 tn/ha, bulb weight with 34.28 g, number of bulblets with 13 and foliar analysis highlighted T5 with 0.48 g/100 g d.s. (dry material). It is concluded that the T4 dose with 750 mL of phosphorus (Wuxal Phosphorus)/200 L of water increased 13.01% in yield in relation to T1; being significant.
Highlights
Fertilizers have not been properly applied for many years; since the variation in the use of chemical inputs has affected the crops in the area, causing problems such as stress in the plant due to accumulation or deficiency of nutrients, pollution to the environment and an increase in the cost of production
Soil analysis For the soil analysis the following procedures were carried out, soil samples were taken in a staggered manner and it was poured into a blanket it was stirred and from there a representative sample of 1 Kg of soil was taken, which was taken to the National Institute of Innovation Agrarian (INIA) - Huaral, which was determined that the soil does not present danger of salts, pH is neutral, has a low concentration of potassium with 92 ppm (12 ppm - 250 ppm) and available phosphorus with 8% (12ppm - 36 ppm). ), average concentration of organic matter with 2.62% (2% - 4%), nitrogen with 0.13% (0.1% - 0.2%) and normal concentration of calcium carbonate
According to the results of the application of the foliar phosphorus in the garlic crop that are detailed in table 5, it was determined that there was only dose effect on commercial yield and number of bulblets; in the other evaluations there were no significance
Summary
Fertilizers have not been properly applied for many years; since the variation in the use of chemical inputs has affected the crops in the area, causing problems such as stress in the plant due to accumulation or deficiency of nutrients, pollution to the environment and an increase in the cost of production This is due to the fact that synthetic fertilizers are increasingly used in order to increase yield without taking into account soil analysis, according to Rodríguez et al (2019) show that modern agricultural practices accelerate soil contamination by the intensive use of fertilizers and pesticides to increase productivity and reduce crop losses. That is why it is essential for photosynthesis and in its physiology and essential for development
