In Cambodia, jute is generally cultivated by broadcasting and it appears to be too thick.
This test was carried out from May to September, 1962. in Tuol Samrong Battambang, to compare the broadcasting and drillings of 6 treatments - 2 different stands per area which are composed of 3 different modes of stand, that is, 2 different row width and 1 zigzag stand on a row.
Results obtained are as follows;
(1) As to the total green matter yield, there is no difference significantly, but broadcasting plot has many useless short stalks which we cannot extract fibers. These useless stalks excluded, statis-tical analysis shows that drillings are always better than broadcasting in the yield of fresh stalks significantly, but among drillings of 6 treatments there is no difference. The highest computed yield of stems (which were defoliated) is 59. 91 tons per hectare.
(2) The average stem length of drillings is superior to that of broadcasting significantly at 1.% level.
The coefficient variance of stem length - that means uniformity of length - has a tendency to increase in broadcasting, but statistically not significant.
(3) Length of fiber is highly correlated with a stem weight, and the later also being highly correlated with a fiber weight, but as to the relation between a stem weight and percentage of fiber recovery, above 90 to 100 gr of stem weight, i, e. above 240 to 250 cm stem length, there is very little difference in the percentage of fiber, staying about 7% in spite of its weight or length. But below these stems the percentage fiber recovery remarkably falls off.
To get much of such weighty or long stems which have high percentage of fiber recovery, drillings are much better than broadcasting and so far as this experiment concerned, drillings of thin spacing are preferred.
(4) It is concluded that several works such as sowing, cultivation, weeding and others considered, drilling of 40 cm row width and about 5.25 cm between hills (not zigzag) may be recommended for stem and fiber production as best.
