Island guano and its effect on the yield of cabbage (Brassica oleracea L) variety Lombarda (Capitata f. rubra) in Colicocha - Huánuco

Abstract

Island guano is one of the best quality natural fertilizers in the world for its high content of nutrients and improves the physical, chemical and microbiological conditions of the soil. The objective of the investigation was to evaluate the effectiveness of island guano in the yield of the red cabbage variety lombarda. It was carried out in the Colicocha Huánuco hamlet positioned at 09 ° 53´34.5” LS, 75 ° 59´49” LO and 2 606 meters above sea level. The methodology used was the Complete Random Block Design (DBCA) with four repetitions and treatments, and they were: 3 t.ha-1 (T1), 4 t. ha-1 (T2), 5 t. ha-1 (T3) and witness (T4). The evaluated variables were: equatorial diameter, polar diameter, pellet weight per plant, experimental net area (ANE) and the yield per hectare. The results of the study indicate that the dose of 5 t.ha-1 of island guano showed a statistically significant result in all the variables evaluated, in the equatorial diameter (23.73 cm), polar diameter (24.80 cm), pellet weight per plant (4.15 kg), by ANE (66.40 kg) and the yield per hectare (70550.00 kg. ha-1).
