Abstract
The field experiment was conducted during kharif-2024 at Pearl Millet Research Station, JAU, Jamnagar to find out the “effect of photosynthate partitioning & remobilization on growth and yield of pearl millet under rainfed condition”. The experiment was laid out in randomized block design with six selected hybrid and replicated thrice. To evaluate the effect of photosynthate partitioning and remobilization on the growth attributes, dry matter accumulation and yield performance of different pearl millet hybrids under rainfed condition. The selected hybrids were MPMH 17, MPMH 21, RHB 173, ABH 1200, Pusa composite 443 and Pusa composite 612 in the field under rainfed condition. The results showed that maximum plant height (166.67 cm) was recorded in AHB-1200 at maturity stage of the crop. The hybrid, AHB-1200 exhibited the maximum leaf dry weight (34.17 and 22.80 g), stem dry weight (54.90 and 177.70 g) and panical dry weight (20.97 and 109.33 g) at anthesis and maturity stage of the crop, respectively. The hybrid, AHB-1200 exhibited significantly highest grain yield (73.92 g/plant) and Harvest Index (23.84%).
