title: Growth and yield of rice as affected by transplanting dates and seedlings per hill under high temperature of Dera Ismail Khan, Pakistan.
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.
