The DNA replication sequence in sex chromosomes of female and male cells of Melandrium album suggests that their pattern is similar to that of mammalian sex chromosomes. Expand
Potato in West Bengal
Genetical Studies in West African Eggplant
The height of plants, leaf indices and weight of fruits in F1 hybrids far exceeded the mean values of two parents in S. melongena L. Expand
Chemical Nature of Chromosomes
It is clear that if the Stedmans' interpretation of the mechanism of the normal Feulgen technique is correct, it should be possible to stain chromosomes directly with the developed nucleal stain, as shown by the results, illustrated in the accompanying photomicrographs, which are obtained with this stain on plant cells.

Effect of gibberellic acid on sprouting, growth of internodes, tuber shape and yield in different varieties of potatoes
Sprouting was hastened by one week by treatment for 5 min, with gibberellic acid (GA) at a concentration of 25 p.m. in newly dug potatoes ofRoyal Kidney andUp-to-Date andVoran, with increased extention of internodes following treatment with GA. Expand
Spray tests for control of potato blight in the hills of West Bengal
Spray tests have been carried out with various fungicides for the control of late blight in high rainfall conditions in the hills of Darjeeling, West Bengal, and under severe late blight conditions Perenox and Dithane gave better results than did the other fungicides. Expand
Fertilizer trials with different sizes of seed potatoes and different planting distances
The highest yield was obtained by using seed tubers of 1 1/2 inches in diameter, 12 tubers to the pound, in combination with 80pound of N2; 160 pounds of P2O5, and 80 pounds of K2O per acre. Expand
Spray tests for control of potato blight in the hills of West Bengal II
Under severe late blight conditions in the hills the disease was succesfully controlled until 136 days after planting in all test plots with different fungicides when sprayed at an interval of 8 and 6 days since there was no appreciable difference in the incidence of infection between plots sprayed at 8-and 6-days’ intervals.
