Resource use efficiency of mandarin orange production in Tinsukia District of Assam

The study was conducted in Tinsukia district of Assam to examine the resource productivity and resource use efficiency in orange production. Results of the ordinary least square (OLS) estimates of the parameters for the sampled orange farms showed that regression co-efficient of plant population was positive and significant in all the size categories of farms. The regression co-efficient of manure and fertilizer was found positive and significant at 1 per cent probability level in marginal and medium farms. The regression co-efficient of human labour was found positive in all the size categories of farms, whereas it was found significant at one per cent probability level in marginal and medium farms. The regression co-efficient of plant protection chemical was found significant at 1 per cent probability level in marginal and small farms showing significant contribution of plant protection chemical to gross income in these farm sizes and there is still scope for increasing the expenditure. The returns to scale in all size categories of farms were well above unity.
