To investigate the combined effect of location, transplanting date and transplanting density on phenology, growth, yield and
radiations use efficiency of rice, a 2-year experiment was conducted at 3 locations (Gujranwala, Hafizabad and Faisalabad) in
Punjab (Pakistan). Six transplanting dates (10th June, 20th June, 30th June, 10th July, 20th July and 30th July) and three
transplanting densities (1, 2 and 3 seedlings per hill) were randomized in main and sub-plots, respectively under Randomized
Complete Block Design with split plot arrangement. The results indicated that most of the studied parameters were affected
significantly. In case of locations, both years average maximum Paddy yield (3249 kg ha-1
), Leaf area index (5.56), Crop
growth rate (25.35 g m-2 day-1
),Paddy yield radiations use efficiency (1.26 g MJ-1
) and Biological yield radiations use efficiency
(5.23 g MJ-1
) were recorded at Gujranwala. Among transplanting dates, average maximum Paddy yield (3688 kg ha-1
), Leaf
area index (6.05), Crop growth rate (28.94 g m-2 day-1
),Paddy yield radiations use efficiency (1.38 g MJ-1
) and Biological yield
radiations use efficiency (5.37 g MJ-1
) were recorded in 30th June, 20th June, 20th July, 30th June and 20th July transplanted rice,
respectively. In case of transplanting densities, maximum Paddy yield (3186 kg ha-1
) and Paddy yield radiations use efficiency
(1.25 g MJ-1
) were observed in 2 seedlings per hill and maximum Leaf area index (5.88), Crop growth rate (24.11 g m-2 day-1
)
and Biological yield radiations use efficiency (5.14 g MJ-1
) were recorded in 3 seedlings per hill transplanted rice.
