The following table shows that the factors affecting production of rubber. Table 3.22 Factors Affecting Production Factors Affecting Production Taluk Kalkulam Vilavancode Thovalai Total Maintenance cost 29 (21) 25 (23) 11 (22) 65 (21) Source: Computed from Primary data Note: Figures in parentheses indicate the percentage to total The above table exhibits that 25 per cent (75) of the respondents feels that tapping, 24 per cent (71) of the respondents are feels that lack of labour, 21 per cent (65) are feels that maintenance cost, 17 per cent (53) are feels that lack of finance, and 12 per cent (36) are feels that rain/storm.

Hence, in modern day’s new technology adopted for tapping and planting rubber trees. So the awareness and training should be given to them. Co-efficient of regression, for Age and sources of production In order to find out the factors that determine the age of NR growers, and the selected nine variables have been regressed on sources of production of NR by the growers’ index. The following regression equation has been framed to ascertain the impact of the variables on awareness. Co-efficient of regression, for Age and sources of production G I = where, GI a a + b1 VC+ b2 TFU+ b3 OP+ b4 OM+ b5 NOI+ b6 MOC+ b7 QOR+ b8 TOVU + b9 MOD = Growers Index = Intercept term VC = Varieties of cultivation TFU = Types of Fertilizers Used OP = Own Plantation 96 Rain/ storm 17 (12.1) 12 (10.9) 7 (14) 36 (12) Lack of labour 24 (17.2) 35 (31.8) 12 (24) 71 (24) Tapping 43 (30.7) 20 (18.1) 12 (24) 75 (25) lack of finance 27 (19.3) 18 (16.4) 8 (16) 53 (17) Total 140 (100) 110 (100) 50 (100) 300 (100)
