ginning percentage with the prevailing mixture of Broach 

 and Ghogari. This is the first year of the trials on a field 

 scale with the ghogari types and as the character of the 

 season was very unfavourable to the cotton crop it is pre- 

 mature to say anything on the relative merits of these types. 

 The outturn results and the ginning percentage of each of 

 the three types are almost equal this year. Pure Broach 

 compares favourably in outturn with the ghogari type but 

 its ginning percentage is low, being 38 against 44 of 

 ghogari. The ginning percentage of all the cotton seems 

 to be very high this year at the expense of quality. No doubt 

 the ghogari type is superior in ginning percentage but the 

 quality of cotton is inferior; in fact, it is Bengal cotton 

 and can never be compared with Broach. 



Dohad. This does not come within the actual zone of 

 the cotton-growing tract. Trials were undertaken to test 

 the behaviour of Bhuri, Cambodia, and N. R. one of the 

 neglectum types, during the last five years with the result 

 that the former two varieties were found quite unsuitable 

 to this tract. They grew very vigorously during the early 

 part of the season but later on they invariably suffered from 

 attacks of pests and were destroyed by frost (the occurrence 

 of which is common) as they occupied the ground for a 

 longer period. It has, however, been found that N. R. 

 cotton is the suitable variety for the black soil area though 

 the period of maturity is rather prolonged on account of 

 the retentive character of the soil. The percentage of 

 cotton to seed is low, 36 against 38 on the Jalgaon Farm 

 whence the seed is obtained. 



In N. R. cotton, some plants produce perfectly naked 

 seed, the naked seed type has been found to possess a very 

 low ginning percentage — 35 only though the fibre is good. 

 The plants are dwarf in size and mature two weeks earlier 

 than the ordinary N. R. It has been proposed to try this 

 type on a fairly large scale during the ensuing year to test 

 both outturn and ginning percentage results. 



The area under cotton in these parts will be restricted 

 as the soils can be double cropped. There is a difficulty
