Response of Summer Groundnut Varieties as Influenced by Plant Geometry

A field experiment was conducted during Zaid 2023 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P.) to study the “Response of summer Groundnut varieties as influenced by plant geometry”. The experimental treatments comprised of three types of Groundnut varieties vi, Kadiri-6, TAG-24, Kadiri Amaravathi and three different planting geometry viz, 30 cm x 15 cm, 35 cm x 15 cm, 45cm x 10 cm, forming total 9 treatment combinations each was replicated thrice and laid out in randomized block design. The results showed that the significantly highest plant height (37.78cm), maximum number of nodules/plant (125.77), highest plant dry weight (22.37 g), maximum number of pods/plant (30.20), maximum number of kernels/pod (1.50), higher seed index (32.20 g), higher seed yield (2.19 t/ha), higher haulm yield (5.20 t/ha), and higher harvest index (35.86%), shelling percentage (55.97%)was recorded in treatment 7 [Kadiri Amravati+ Spacing (30 cm x 15 cm)]. Similarly, maximum gross return (141650.00 INR/ha), net return (97386.00 INR/ha) and benefit cost ratio (2.20) was also recorded in treatment 7 Kadiri Amaravathi + Spacing (30 cm x 15 cm) as compared to other treatments. It was concluded that in Groundnut variety with the combination of Kadiri Amaravathi and spacing of (30cmx15cm) in Treatment-7 was recorded highest seed yield and B: C ratio.
