Effect of spacing and irrigations on growth and yield of groundnut (Arachis hypogaea L)

Abstract

A field experiment was conducted during Zaid 2022 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P). The experiment was laid out in Randomized block design with ten treatments replicated thrice. The treatment combinations are mentioned as T1 - 30 × 10 cm + 2 Irrigations (flowering stage, pod formation stage), T2 - 30 × 10 cm + 3 Irrigations (seedling stage, flowering stage, pod formation stage), T3 - 30 × 10 cm + 4 Irrigations (seedling stage, vegetative stage, flowering stage, pod formation stage), T4 - 35 × 10 cm + 2 Irrigations (flowering stage, pod formation stage), T5 - 35 × 10 cm + 3 Irrigations (seedling stage, flowering stage, pod formation stage), T6 - 35 × 10 cm + 4 Irrigations (seedling stage, vegetative stage, flowering stage, pod formation stage), T7 - 40 × 10 cm + 2 Irrigations (flowering stage, pod formation stage), T8 - 40 × 10 cm + 3 Irrigations (seedling stage, flowering stage, pod formation stage), T9 - 40 × 10 cm + 4 Irrigations (seedling stage, vegetative stage, flowering stage, pod formation stage), T10 - control (RDF) - 25:50:75 NPK kg/ha The important findings of the experiment have been summarized and concluded here under the objectives taken. The application of 35 × 10 cm + 4 Irrigations (seedling stage, vegetative stage, flowering stage, pod formation stage) recorded significantly higher Plant height (68.84 cm), number of branches per plant (16.73), Number of nodules per plant (26.27), Plant dry weight (42.97 g/plant), Significantly maximum number of pods/plant (50.80), Seeds/pod (2.93) was obtained in the treatment of 35 × 10 cm + 4 Irrigations (seedling stage, vegetative stage, flowering stage, pod formation stage).
