Effect of phosphorus doses to obtain higher yields in the cultivation of garlic (Allium sativum L.), at the district of Barranca [Efecto de las dosis de fósforo para obtener mayor rendimiento en el cultivo de ajo (Allium sativum L.), en el distrito de Barranca]

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.
