128 EXPERIMENT STATION RECORD. 



As shown by the table, the result of irrigating bush beans was very 

 satisfactory, the yield from the irrigated plat being 45 lbs. of pods, while 

 the average yield of 9 unirrigated plats was 17 lbs. 1 oz. The quality 

 of the irrigated beans was also superior. 



The period of fruitage with peppers was prolonged and the yield 

 nearly doubled, the irrigated i^lat giving 147 lbs. against 80 lbs. from 

 an unirrigated plat. In addition, the fruit from the watered plants was 

 firm and plump and of fine color and quality, thus being of greater 

 market value. 



The leaf development of turnips was greatly increased by irrigation, 

 but, although there was an increased growth of roots, they were 

 destroyed by the club root, which raged with unusual virulence in the 

 moistened soil. 



The soil of the celery plat was not the most favorable, but the yield 

 of the irrigated plat was 42 lbs., while the unirrigated plat gave only 

 17^ lbs. The market value of the crop produced from the irrigated 

 plat was 8 times tliat produced without the aid of artificial watering. 

 The loss from outside leaves and roots in preparing the plants for market 

 was 28 per cent in the case of the irrigated plants against 40 per cent 

 in the uonirrigated plants. 



Cassava, O. Clute {Florida Sta. Bui. 35, pp. 331-339, pis. 4.)— This 

 discusses the propagation, manuring, culture, and harvesting of cassava 

 {Maniliot aipi), and the value of the roots as food for ujan and animals. 



The use of cassava for preparing tapioca, starch, and glucose is 

 briefly mentioned, and the botanical relationships of cassava among the 

 Euphorbiaceae are discussed. An analysis of cassava root is taken from 

 Bulletin 44 of the Division of Chemistry of this Department. The 

 illustrations are from photographs showing cassava plants and roots. 



Taro and tropical yam, O. Clute {Florida Sta. Bid. 35, pp. 346- 

 348). — This gives brief notes on taro {Colocasla antiquornm) and the 

 tropical yam {Dioscorea sp.) now being grown on the station grounds. 

 Both plants produce roots of considerable size and of agreeable flavor, 

 although they are not thought to be as desiral)le as potatoes or sweet 

 potatoes. 



The pole Lima beans, L. H. Bailey {Neic Yorii Cornell Sta. Bui. 

 115, pp. 293-314, Jigs. 17). — This bulletin comprises descriptive, com- 

 parative, and cultural notes on Lima beans {Phaseolus lunatiis) as grown 

 at the station. All the 3 types of Lima beans — sieva, flat, and potato 

 Limas — were grown. Three varieties of the sieva type, 9 of the large 

 flat Limas, and 2 of the potato variety are noted. 



The sievas are valuable chiefly because of their earliness, since the 

 beans are neither as large nor as rich as those of the large Limas. The 

 Willow Leaf variety is interesting on account of its peculiar foliage. 

 Of the large flat Limas the variety Kaighn proved best, although Jersey 

 and May Champion were also satisfactory. Of the potato Limas Dreer 

 Improved produced a good yield of beans of high. quality.
