Meen, Jitendr Singh, Poonm 1 nd Bhrt Bhusn Centrl Institute of Post Hrvest Engineering nd Technology, Abohr, Punjb ABSTRACT A field tril comprising totl ten tretments viz control three coloured shde nets (Green 35% nd 50%, Red & Blck 50%), one insect net 50 mesh t three metre height, two evportive cooling tretments (over tree fogger nd micro sprinkler) t 2.5 meter height nd two folir spry tretment (Kolin 4% nd Borx 0.4%) during the fruit development stge) ws undertken on pomegrnte Cv. Mridul during Study ws imed to evlute the efficiency of different tretments ginst sunburn ttck nd pomegrnte fruit qulity under high solr rdition during summer months. Significnt difference ws recorded in fruit weight nd yield. No significnt difference ws observed in TSS ( 0 Brix). Sun burn ttck ws recorded less (3.2%) in blck colour shding compred to control (9%). No significnt difference ws found for bcteri burnt disese in openly grown nd TSS but cidity nd Vitmin-C ws reduced in shdnets. 1 funs'kky; Qly iz.kkyh vuql/kku] eksnhiqje] esjb (m-iz-) 1 Project Directorte for Frming System Reserch, Modipurm, Meerut (M.P.)
