Influence of Different Spacing and Organic Manure on the Yield and Economics of Groundnut (Arachis hypogea L.)

Aim: The trail was taken to find out the influence of different spacing and organic manure on the yield and economics of the groundnut (Arachis hypogea L.)

Study Design: Factorial randomized block design.

Place and Duration of Study: The experiment was taken during the kharif season of 2021 at G.H. Raisoni University at Agronomy farm, Chhindwara, M.P.

Methodology: The set of nine treatment combination consist of three different spacing and three different OM which is applied at 12 kg/ha of FYM, at 6 kg/ha VC and at 6 kg/ha of PM. The experiment was carried out in Factorial Randomized Block Design with three replication and the treatment combination is T1: S1O1 (30 cm x 10 cm + FYM), T2: S1O2 (30 cm x 10 cm + VC), T3: S1O3 (30 cm x 10 cm + PM), T4: S2O1 (30 cm x 15 cm + FYM), T5: S2O2 (30 cm x 15 cm +VC), T6: S2O3 (30 cm x 15 cm + PM), T7: S3O1 (45 cm x 10 cm + FYM), T8: S3O2 (45 cm x 10 cm + VC) and T9: S3O3 (45 cm x 10 cm + PM) and total number of plots is 27. At the time of experiment, the maximum mean of temperature was 41.60C whereas the minimum mean temperature was 5.680C. The economics of groundnut crop was calculated as per the fundamental market prices of the input and produced during the kharif season 2021.

Results: Maximum no. of pods/plant (30.67), length of pod (2.72), no. of kernels/pod (2.07), seed index (43.22 g), shelling percentage (74.76 %), pod weight/plant (18.66 g), pod yield/plot (1.53 kg), pod yield (63.01 kg/ha), kernel yield (23.45 kg/ha), haulm yield (39.56 kg/ha) and harvest index (24.07 %) were recorded with T3–30 cm x 10 cm with Poultry manure at 30, 60 and 90 DAS.

Conclusion: Based on this experiment, it was said that with spacing 30cm x 10cm in combination with poultry manure gives the maximum and significantly higher kernel yield (23.45 kg/ha), gross return Rs.1,72,022.00/ha) as well as highest net return Rs.99,367.00)/ha).
