Description |
A field experiment was conducted during late ·Khari!, 1988 in split plot design with three cultivars viz., PHG-9, C0-1 and PDM-1 to investigate the effect of .sowing dates on phenology, growth and yield of horsegram under rainfed conditions. The sowings were done on September 6 and 20, October 4 and .18 and November 3 and 19. Sowings at different dates affected the crop ontogeny, period of vegetative growth, morphology of crop, leaf production and senescence, dry matter production, flowering date, maturity and finally the seed yield. The plant height and number of branches were higher in the September 6 sowing and decreased with every delay .in . sowing. Days to flowering and maturity were early in later sowings compared to early sowings. Days to flowering ·exhibited strong correlation with daylength while days to maturity was associated with mean temperature. Sowing on October 4 or 18 was much productive in compari~to either earlier o~ later sowings. Dry matter accumulated into stem and lamina and total dry matter produced was maximum at first sowing (September 6) and · decreased with delay in sowing. Dry matter of pods increased from Septemb~r 6 to Oct~ber 4 sowing and then decreased. Total dry matter was significantly correlated with LAI, daylength and mean temperature.Maximum and minimum values of CGR were recorded with October 4 and November 19 sowings respectively. There was increase in RGR and NAR values with every delay in sowing. LAR and SLA recorded higher values in October 4 and 18 sowings. . There ~ -2 was~ decr~ase in ·number of pods m · and increase in number ot seeds pod- with each delay in sowing. The maximum 100-seed weight was recorded with September 6 and October 4 sowings. There was~1ncrease in harvest index with delay in sowings except in last (No~ember 19) sowing where it was decreased. The highest seed yield (1457 kg ha-i)was recorded with October 4 sowing which was on par with October 18 sowing (1452 kg ha-1). Sowing beyond October 18 drastically reduced the seed yield. There was significant and positive correlation between seed yield and weight of pods while number of pods was strongly associated with weight ot pods. Amons cultivars, C0-1 produced higher dry matter (393.41 g m-2), weight of pods and number of pods and recorde~ the highest yield (1152 kg ha-1). From the study it was concluded that sowing of horsegram in the first fortnight of October gave higher seed · yield and the ev. C0-1 performed better among all the cultivars and recorded hignest yield. |
