EXPERIMENTS WITH RICE. 



The following account of the experi- 

 ments with rice carried on under the 

 control of the Director of the Depart- 

 ment of Science and Agriculture at the 

 Experimental Fields of the Botanic 

 Gardens is printed from the Report al- 

 ready referred to under " Sugar-cane 

 Experiments." 



Varieties under Experiments. 



In April 1906, seventy-nine different 

 varieties of rice were sown on the seed- 

 beds at the Experimental Fields. Among 

 these were included the ordinary Creole 

 rice, the Berbice Creole rice, Carolina 

 Golden Grain, Japan rice, Honduras rice 

 and Carolina rice, forty-two Ceylon 

 varieties and twenty-two varieties 

 received from Dr. Van Hall, the Royal 

 Commissioner of Agriculture for the 

 Dutch West Indies. Of the varieties 

 sown thirty-seven were Upland, Hill or 

 dry rice, the remainder being Lowland 

 or wet rice. 



Manurial Experiments with 

 Phosphates. 

 The rice-beds were prepared and 

 manured in May, the manures used being 

 slag-phosphates, super-phosphate of lime 

 and the so-called " Basic super-phos- 

 phate of lime," a super-phosphate neutra- 

 lised by addition of lime in accordance 

 with a suggestion of Mr. John Hughes, 

 F. I. C, etc., Chemist to the Ceylon 

 Planters' Association. The experiments 

 were arranged so as to allow of a com- 

 parison of the increases, if any, due to 

 these various phosphatic manurings. 



The fii'st-metioued was applied at the 

 rate of 6 cwts, to the acre, the two latter 

 at the rate of 4 cwts. per acre 



The tranfer of the youne: rice-plants 

 from the seed-beds to the Experimental 

 Fields was commenced in the first week 

 of June and completed by the 20th. 



The varieties were practically all in 

 ear in August whilst the Japan dwarf 

 rice ripened during that month and was 

 reaped on the 29th. A commencement 

 was made of the general reaping in the 

 second week of September and this was 

 completed in the first week of October. 



In January, 1907, a clearance was com- 

 menced for an extension of the rice- 

 field. After the land was cleared it was 

 fenced with barbed wire so that the 

 whole of the experimental rice-field is 

 now surrounded by a ring-fence. 



In February the irrigation system was 

 re-modelled so that the water for this 

 field is now obtained independently of 

 the wide trench in the Avenue of the 

 Botanic Gardens, thus preventing wast- 

 age. By the end of March all the beds 

 in the extension which are to be used 

 for rice-experiments were ready for this 

 purpose. They were forked and prepared 

 for actual planting early in May. 



The seed-beds were sown on April 17, 

 and the young plants were transferred 

 to the experimental plots from the 

 22nd to the 30th of May. Certain of the 

 plots were again manured in accordance 

 with the system mentioned above.
