Abstract/ Executive Summary:

The study was conducted at the farmers’ field of farming System Research and Development Site, Razakhali, Patuakhali district under Ganges Tidal Floodplain Zone (AEZ-13) during late Rabi in 2005-2006 to find out suitable plant spacing for two groundnut varieties, viz., Dhaka-1, an erect Spanish type and DG-2, a semi-spreading Virginia type. The experiment was laid out in a split plot design with six dispersed replications. The result of the experiment revealed that erect type groundnut variety, like Dhaka-1 required closer spacing (30 cm × 10 cm) to express its maximum yield potentiality, on the other hand spreading or semi-spreading type groundnut variety required wider plant spacing (40 cm × 20 cm) to express its maximum yield potentiality.

Keywords: Plant spacing, Yield, Groundnut

Location: Farmers’ field of farming System Research and Development Site, Razakhali, Patuakhali district

Start Date: 20-12-2005

End Date: 30-05-2006

Program Area: Crop-Soil-Water Management

Commodity: Ground nut

Objectives:

Objective of the study was to determine the proper arrangement of row and plant spacing for higher yield of two groundnut varieties having different growth habits.

Methodology:

The experiment was conducted during 2005-2006 in the late Rabi season at On- Farm Research Division (OFRD), Bangladesh Agricultural Research Institute (BARI), Patuakhali. The soil contained 1.3% OM with a pH of 5.9. Initial Ca, Mg and K contents were 5.9, 1.52 and 0.28 meq/100 g, total nitrogen 0.15% and P, S and Zn contents were 10.6, 28.7 and 1.2 μg/g, respectively. Fertilizers were applied at the rate of 25-30-40 kg N-P-K/ha supplied from Urea, Triple Super Phosphate (TSP) and Muriate of Potash (MP), respectively. Fifty percent of urea and 100% of TSP and MP were applied during final land preparation. The remaining 50% of the urea was top dressed at flower initiation stage. The experiment was conducted in a split- split- plot design with 3 replications. The two varieties (Dhaka-1 and DG-2) were assigned to the main plots, three row spacing (20 cm, 30 cm and 40 cm) were in sub plots and three plant spacing (10 cm, 15 cm and 20 cm) were in sub-sub-plots. The unit plot size was 4 m × 5 m. The variety Dhaka-1, an erect and DG-2, a semi spreading type were sown at 5 cm depth on 22 December 2005. Missing hills were replanted within the first week of germination and three additional irrigations were given on 25 January, 20 February and 2 April 2006. There was negligible incidence of insects and pests. Ten plants were selected randomly at the initial growth stage in each plot for sampling. Observations were made on pod yield/ha, dry weight of pods/plant (g), number of mature pods/plant, shelling percentage, 1000-seed weight (g), pod bearing length of stem/plant (cm), number of primary branches/plant and harvest index (%). Shelling percentage was calculated as weight of seeds/weight of pods × 100. The variety Dhaka-1 and DG-2 were harvested on 30 May 2006 and sun dried up to 9% moisture level. The data on all the parameters were analyzed and mean differences were measured by LSD.

Achievement/Findings:

The findings suggested that varieties of different growth habits required different spacing to express their yield potentials, Dhaka-1 required closer spacing of 20 cm × 10 cm while DG-2 required wider spacing of 40 cm × 20 cm to produce maximum yield. However, considering seed cost and oil yield, 30 cm × 10 cm spacing for Dhaka-1 and 40 cm × 20 cm for DG-2 may be considered as optimum spacing to get maximum benefit from cultivation of these two groundnut varieties.
