AGROBIOLOGICAL EVALUATION AND PRODUCTIVITY OF ARUCOLA VARIETIES IN THE DAGESTAN REPUBLIC

Abstract

The objective of the work is to optimize technological methods for cultivating arugula to obtain green mass in the Derbent district of the Republic of Dagestan. The study was conducted from 2021 to 2024 at the Dagestan Experimental station (the branch of All-Russian research institute). During the study of rare crops (arugula, Eruca sativa, wallrocket) were determined the seed and green mass productivity, commercial quality and seed plants height. To obtain green mass in the open ground of the Derbent district, the optimal sowing dates for arugula are from September to the first ten days of December, and the second ten days of February to May inclusive. In the greenhouse conditions sowing was carried out all year round. In the Southern Dagestan conditions were distinguished the following samples: by green mass per 1 m2 – Eruca sativa (3.09 kg); Eruca sativa Proito (2.99) and Olivett two-row (2.61); by the number of seeds per plot - Eruca sativa Proito (730 g), Arugula (470), Indau broadleaf (420) and wallrocket Olivette (410); by the weight of 1000 seeds - Eruca sativa Proito (2.78 pcs./g); Arugula (2.23) and wallrocket Olivette (2.17) with the maximum number of breeding valuable traits. Arugula sample may be recommended for using in breeding programs for the creating new higher-end varieties in the Derbent District and outside the Republic of Dagestan.
