SUMMARY :In research study conducted on mango growers in Kokan region of Maharashtra state with the major objectives of measuring the socio-economic characteristics and knowledge level of mango growers on plant protection measures. It was observed that the more than half (52.50 %) of the respondents were in middle age group, having (65.00 %) secondary to higher secondary level of education and medium size of land holding (61.66 %). More than half of the (57.50 %) of the respondents possessed 2 to 10.9 ha. of land under mango cultivation, medium size of family (54.16 %), having low to medium level of income (79.16 %) and medium level of experience in mango cultivation (77.50 %). Nearly three fourth (70.00 %) of the respondents had medium social participation, majority of respondents i.e. 71.66 per cent had medium level of mass media exposure, nearly two third (67.50 %) of the respondents had medium level risk orientation, majority of them had (84.16 %) good level of change proneness and majority of respondent had medium level of achievement motivation and economic motivation (64.16 % and 37.50 %), respectively. The majority of mango growers (65.83 %) had 'medium' level of knowledge about plant protective measures indicating need for training in this aspect of cultivation.How to cite this article : Gondkar, S.S., Joshi, Vister, Varpe, Santosh and Chaudhari, Pooja (2017).

A field experiment was carried out at Central Sugarcane Research Station Padegaon, during 2011-12 to 2013-14 to assess the crop weather relationship in preseasonal sugarcane (var. CoM 0265). Treatments were comprised of nine planting dates at 15 days interval starting from 15th October to 15th February. The results indicated that the early planting produced highest cane and CCS (commercialcane sugar) yield. Significantly the highest brix (21.3), sucrose (20.4%), purity (96.8%) and CCS (14.6%) were observed under early planting of sugarcane on 15th October, which was at par with the treatment 01st November, 15th November, 1st December planting. At harvest cane and CCS yield of sugarcane was positively correlated with maximum temperature, wind velocity and pan evaporation. Significantly positive correlation of millable cane, weight per cane was observed with cane and CCS yield.
