The Effect of Plant Spacing and Planting Model on Multiple Cropping of Red Chili (Capsicum annuum L.) and Shallot (Allium ascalonicum L.) under Saline Soil Conditions

A field experiment was conducted from October 2018 to April 2019 at Sidomukti Village, Brondong Sub-District of Lamongan Regency, Province of East Java. The research was performed with the aim of examining and obtaining appropriate combinations of plant spacing and planting model for red chili (Capsicum annuum L.) and shallot (Allium ascalonicum L.) plants in saline soil conditions. The utilized design on this research was randomized block design. This research consists of 6 combinations that are repeated 4 times, resulting in 24 experimental units. Based on the research, it was found that the treatment of multiple cropping of red chilies i.e. 2 rows of shallot plants between rows of red chilies have land equivalence ratios (LER) greater than 1, being 1.32 and 1.41, which indicates that the treatment of multiple cropping leads to higher land effectiveness.
