SUMMARY

A field experiment was conducted at Dryland Research Area, CCS Haryana Agricultural University, Hisar (Haryana), India during rainy season (Kharif) of 2018. Two cluster bean genotypes (X-10 and HG 2-20) were grown in two crop geometries (30 cm ×10 cm and 45 cm × 10 cm) at three fertilizer levels (75, 100 and 125 per cent RDF) with split plot design in three replicates to find out the suitable genotype, crop geometry and fertilizer dose for kharif season. Among the genotypes, no significant difference was observed for seed yield. However, the seed yield of HG 2-20 was 6.07 per cent higher over X-10. Maximum B : C ratio (1.16) was fetched in HG 2-20 followed by X-10. Among different crop geometries, highest seed yield (473.9 kg/ha) was recorded at 45 cm × 10 cm which was significantly higher over 30 cm × 10 cm. Maximum B : C ratio (1.17) was fetched with the crop geometry 45 cm × 10 cm which was significantly superior over 30 cm ×10 cm. Among fertilizer levels, highest seed yield (653.76 kg/ha) was recorded with the application of 125 per cent RDF which was on a par with 100 per cent RDF. The seed yield recorded with 125 % RDF was 0.55 and 12.75 per cent higher over 100 and 75 per cent RDF, respectively. However, maximum B : C ratio (1.16) was fetched with the application of 100 per cent RDF which was on a par with 125 per cent RDF. In nutshell, the crop geometry 45 cm × 10 cm and 100 per cent recommended dose of fertilizer (basal application of 40 kg P2O5+20 kg N/ha) were found to be suitable for both the genotypes.
