Yield of habanero pepper (Capsicum chinense Jacq.) under different NPK levels in Campeche, Mexico

In the Yucatan Peninsula, the habanero pepper ( Capsicum chinense Jacq.) Is one of the most in -demand and valuable agricultural products . Improving field productivity implies fostering the development of regional producers. This research aimed to evaluate different NPK (Nitrogen, Phosphorus, and Potassium) fertilization formulas in open-field cultivation of habanero peppers. The experiment was conducted at the Xamant & uacute;n Experimental Field of the Chin & aacute; Institute of Technology, Campeche, Mexico. Five fertilization formulas were assessed: 150-50-200, 200-100-240, 250-150-280, 300-200-320 , and 350-250-360, using a fertigation system for habanero pepper plants. The study variables evaluated were the number of flowers per plant (NFP), number of fruits per plant (NFRP), fruit length (FL), fruit diameter (ED), and fresh fruit yield per plant (FFY). The results indicate that the 350250-360 formula was the best treatment for NFRP, FL, ED , and FFY, obtaining an average yield of 41,259 kg ha -1 . The findings suggest that using higher doses than recommended increases fruit production per plant.
