The objective was to evaluate the agronomic characteristics and productivity of peanuts BRS 423 OL submitted to different spacing and populations in two consecutive harvests. The experiments were carried out in the agricultural years 2018/19 and 2019/20 in the experimental area of the Federal Institute of Education, Science and Technology of Mato Grosso -- Campus São Vicente, Campo Verde Reference Center, located in the municipality of Campo Verde -- MT. The experimental design used was in randomized blocks, with five replications, and the plots consisted of two lines three meters long, with an interval of two meters between plots. The cultivar used was BRS 423 OL, and the treatments were: 1 -- Population of 222,222 plants ha-1 in the spacing of 0.90 m between rows and 20 plants m-1, 2 -- Population of 222,222 plants ha-1 in the spacing 0.73 m x 0.17 m between double rows and 10 plants m-1, 3 -- Population of 285,714 plants ha-1 in the spacing of 0.70 m between rows and 20 plants m-1 and 4 -- Population of 214,285 plants ha-1 in the spacing of 0.70 m between rows and 15 plants m-1. In the field conditions in which this research was developed, it can be concluded that: Plant heights, dry weight per plant, number of branches per plant and number of grains per pod were not significantly influenced in the two agricultural years due to the different peanut spacing and population densities BRS 423 OL. In the 2019/20 agricultural year, pod yields differed statistically, with a population of 222,222 plants ha-1 under spacing of 0.73 m x 0.17 m and 10 plants m-1 and a plant population of 214,285 plants ha-1 under spacing. 0.70 m and 15 plants m-1 were the most productive.

An experiment was conducted according to randomized complete design to determine best plant spacing and agronomic traits at research farm PMAS Arid Agriculture University Research Farm Chakwal Road, Rawalpindi, during 2008-2009. Three plant spacing's (5, 10, 15 cm) and three row spacing's (10, 20, 30 cm) comprised of the following treatment combinations (T1= 5?10 cm, T2= 5?20 cm, T3= 5?30 cm, T4= 10?10 cm, T5= 10?20 cm, T6= 10?30 cm, T7= 15?10 cm, T8= 15?20 cm, T9=15?30 cm) under rain-fed conditions. The net plot size was 2?6 m with three replications. Days to emergence, plant height at maturity, number of branches per plant, number of capsules per plant, number of seed per capsule, 1000- seed weight, seed capsule ratio, seed yield per plot, biological yield, harvest index, oil concentration and fresh weight of weeds was observed. All agronomic attributes were significantly effected at 15?30 cm spacing, along with oil concentration and fresh weight of weeds, while 10?10 cm row to row and plant to plant spacing had no significant effect. Plant height (cm), number of capsules per plant was maximum for plant geometry of 15?30 cm and lesser amount of weeds. An increase in row and plant spacing led to significantly higher of branching. Higher plant and row spacing resulted in non- consistent increase in the number of seeds per capsule. Seed yield increased with higher row to row and plant to plant spacings. Yield were lower at the narrow (10?10 cm) row and plant spacing's, compared to higher of 15?30 cm spacing. Thus, it is concluded from this study that Linola should be grown at 300-450 cm grids for higher yield output. [ABSTRACT FROM AUTHOR]
