Abstract

The deficiency of water sources and soil fertility are obstacles to producing peanuts in dry land. One of effort to increase production on dry land is the utilization of PGPR biofertilizers. This study aimed to determine the growth of plants and root nodules of several peanut genotypes applied with PGPR, to understand the interaction between several peanut genotypes and PGPR on plant growth and root nodules, and to examine the relationship between water deficit conditions and the formation of root nodules. This experiment used a Complete Randomized Design-split split-plot design with the main plots being D0 = optimal conditions (no water deficit) and D1 = water deficit. The subplots were P0 = no PGPR and P1 = with PGPR. The sub-subplots consisted of five peanut genotypes: V1 = Hypoma-I, V2 = Domba, V3 = Talam, V4 = Bison, and V5 = G300-II. The observations showed that the addition of PGPR resulted in higher plant growth compared to those without PGPR and had more effective root nodules in nitrogen fixation compared to treatments without PGPR. The application of PGPR and genotype did not show significant interaction on plant growth and root nodules under water deficit conditions. Water deficit significantly affected all parameters of plant growth and root nodules. PGPR significantly affected the parameters of leaf number rate, nodule number, and nodule weight. Genotype significantly affected the plant height rate. The interaction of water deficit and genotype significantly affected the leaf number rate, while the interaction of water deficit and PGPR, and the interaction of PGPR and genotype did not significantly affect all observation parameters.

Abstract

Drought and shade stress often occur together in peanut plants. Sunlight and water are the main factors that determine the growth of peanut plants. This study aimed to determine the behavior of several peanut genotypes under conditions of sunlight and water deficit. This research was conducted using a Completely Randomized Design-Split Plot Design with three replications. The treatments to be tested were double stresses (sun light and water deficit) and no stress (control) factors as the main plot and peanut genotype factors, namely Takar-1, Domba, Bison, G2T5, and G19-UI as subplots. The results showed that the peanut genotypes had different behaviors under double stresses (sunlight and water deficit). Peanut plants under double stress caused a reduction in pod dry weight, number of pods, root dry weight, and chlorophyll-a levels compared to those without stress. Peanut genotype G19-UI resulted in the lowest percentage reduction in pod dry weight and number of pods per plant, namely 58.79% and 43.75% under double stresses, respectively
