Research on ischolar_mainstock in mango is very limited in our country. Kalapady was reported to be a dwarfing ischolar_mainstock. Recent trend among mango growers is to high density orcharding with dwarfening nature of the varietie. Efforts were made at Agriculture Research Station, Mulde, to study comparative performance of Ratna, Alphonso and Kesar mango on Vellaikolamban and mixed ischolar_mainstock i.e., heterozygous seedling stock and the effect of ischolar_mainstock on a scion under high density of 5m x 5m spacing. Results indicated that use of Vellaikolamban ischolar_mainstock reduced plant volume in scion cv. Alphonso by 39.1%, followed by 24.9% in Ratna and 26.5% in cv. Kesar. As volume of the canopy was reduced, it directly influenced fruit yield cvs. Alphonso and Ratna. However, reduction in canopy volume had a positive influence on yield in cv. Kesar. Net returns of Rs.38,629/- per ha were maximum for Kesar with the ischolar_mainstock Vellaikolamban.Keywords

A field trial was conducted at Regional Fruit Research Station, Vengurle, Dist. Sindhudurg, (Maharashtra) to assess the efficacy of Ethrel® in relation to flowering behavior and yield enhancement in cashew on seven year old Cashew trees of Vengurle -7 variety during 2008-09. Three sprays of Ethrel® @ 100 ppm, 200 ppm and 400 ppm along with water spray were given before flushing, after flushing and during fruit-set. Control consisted of no. spray. Among treatments, Ethrel® @ 100 ppm significantly increased number of flowering panicles m-2 (12.0), number of perfect flowers per panicle (52.8), fruit-set m-2 (28.8), number of nuts per panicle (2.9) and yield tree-1 ( 1.51 kg tree-1) than control and water spray. Thus, lower concentration of Ethrel® had a beneficial effect on cashew.Keywords
