Lasit fáddágilkoriid | Čoahkkáigeassu: | Peanuts are an oilseed which is highly valued worldwide and is present in the diet of a large part of the population and for many peoples is the main source of protein and lipids. The optimal density of plants is determined by the requirements of the species considered and by environmental factors that directly influence the development of plants and, consequently, the final productivity of the crop. The objectives of this research were: i) Validate the agronomic adaptation of two peanut varieties on yield. ii) Measure the effect of four seed densities on peanut yield. iii) Carry out the economic analysis of partial budget (AEPP) and calculate the marginal rate of return (TMR %). The present essay was carried out in the province of Los Ríos, Urdaneta canton, Ricaurte parisha and San José de Pijullo. The experimental material used was two varieties of peanuts from the National Oilseeds Program of the National Institute of Agricultural Research-INIAP, EELS: INIAP-380 and INIAP-382 Caramelo. The variety that best adapts and had the highest yield. Factors under study were Factor A: Peanut varieties, with two types: A1: INIAP-380 A2: INIAP-382 Caramelo. Factor B: Four seed densities. Design Type: Random Blocks in factorial arrangement of 2 x 4 x 3 repetitions. We performed Variance Analysis, Tukey test for interactions and polynomial trends. The agronomic characteristics and yield of the two varieties of peanut were very different and depended on the population densities of seed and their genotype-environment interaction. For this agro-ecological zone was INIAP-382 Caramelo with 1771.32 kg/ha. The density that yielded the highest yield was B2: (20 plants/m2), with 1818.35 kg/ha. The increase in peanut yield was directly related to the components: Pods per plant (VP), Grains per plant (GP) and Grain weight (PG). The variety with the highest yield potential, selected for this agroecological zone and at the planting time of October 26, 2015 was: INIAP-382 Caramelo. |
