Abstract: | Studies were initiated for two consecutive years to find out the effect of time of transplanting and seedlings hill−1 on the productivity of rice in Dera Ismail Khan district of North West Frontier Province (NWFP), Pakistan. The experiment
was laid out in a randomized complete block design with split plot arrangements. Main plots consisted of four transplanting
dates viz. 20th and 27th of June and 4th and 11th of July while sub-plots contained 1, 2, 3 or 4 seedlings hill−1. Among transplanting dates, June 20th planted crop gave highest paddy yield and net return with 1 seedling hill−1. It explains that the use of more seedlings hill−1 not only adds to cost but is also a mere wastage of natural resources. Based on research findings, we conclude that the use
of 1 seedling hill−1 is most appropriate for timely sowing otherwise 4 seedlings hill−1 should be used to compensate for the yield gap in late transplanted rice. |
