Maharashtra state is nowadays known as the economic power of the country. Climate change makes agriculture more difficult to sustain with higher frequencies of changing temperature, erratic rainfall, increased salinity as well as a rise in sea level. These phenomena have direct impact on crop yield and quality of produce also. The various weather parameters effect on cashew nut yield. So far few studies were conducted in this direction and none of them indicated that critical periods of nut development during which weather factors play a critical role. A survey was conducted under South konkan region of Maharashtra for the year 2006-07 to 2014-15 with an objective to find out the relationship between the total yield of cashew nut influenced by various weather parameters viz., temperature, relative humidity, rainfall received and number of rainy days. The present study on weather parameters indicated that the rainy days in preceding rainy season proved the immediate determinant of yield in cashew production. The rainy days during May are considerably low and moderately high during June. This situation provides a scope of studies to the role of irrigation to cashew orchard during this particular period by modern methods such as drip irrigation. Source

The experiment was laid out to evaluate chewing type of mango varieties as well as the performance of mango varieties ideal for juicy purpose at Regional Fruit Research Station, Vengurle. The study was conducted with six different mango varieties, viz. Amrapali, Benganpalli, Pairi, Pulihara, Suvarnrekha and Karutha Kolumban with the parameters like vegetative, flowering, fruiting, yield attributes and physico- chemical properties. From these studies it reveals that, Suvarnrekha, Amrapali and Benganpalli have shown good yield attributes as compared to Pairi. However, in physico-chemical properties Benganpalli and Suvarnrekha were performing very well compared to Pairi. Amrapali, Suvarnrekha and Pairi have excellent taste compared to rest of the mango varieties under study. From the above study it could be concluded that, out of six mango varieties tasted for juicy type Pairi, Amrapali, Benganpalli and Suvarnrekha are found good and economically profitable for commercial cultivation.

Flower thrips considered to be minor pest of cashew is now becoming very serious pest in cashew growing tract of Maharashtra and Goa causing considerable yield losses. To knowing the importance of pest, it is necessary to evaluate newer insecticides against flower thrips. Hence, the study was conducted in 2007-08 at Regional Fruit Research Station, Vengurle, Dist. Sindhudurg (M.S.). On the evidence of data it is found that the treatment T 4 (Lambda-cyhalothrin 0.003%) was found most effective treatment for management of thrips in cashew followed by treatment T 3. (Triazophos 0.01%) in nut and apple stages. Source

A field survey was carried out to find out the predatory species of spider of cashew tea mosquito bug (Helopiltis antonii) during the year 2014-15at AICRP - cashew Regional Fruit Research Station Vengurle. The data revealed that total 18 species of 6 six different family observed in cashew orchard during the year 2014-15.The family oxyopidae (269 individual), salticidae (160 individual) are the most pre dominate spider family observed in cashew however the family Clubionidae and Gnaphosidae recorded less than five individual. The spider Telamonia dimididata (Salticidae) and Oxyopes shweta (Oxyopidae) was the major predator of cashew tea mosquito bug. The season of occurrence the spider of 9 species collected during summer season, 15 species collected during monsoon season and 9 species during winter season, while six species collected throughout the year.

Field screening to natural infestation of tea mosquito bug was done for seven consecutive years, in total 18 cashew accessions consisting of released cultivars, promising hybrids and other accessions. The screening trail was conducted at the Regional Fruit Research Station, Vengurle during the years 2004-05 to 2010-11. The damage to the shoot, panicle and nut surface was assessed by scoring in the 0-4 scale system. The result indicated that all the accession are susceptible to tea mosquito bug infestation with not any resistant/tolerant to the target insect pest. The intensity of percent infestation was found to vary among the accessions. Source
