COMPARATIVE STUDY ON POMEGRANATE (Punica granatum L.) Cv. MRIDULAUNDER COLOUR SHADE NETS, EVAPORATIVE COOLING AND FOLIAR SPRAY

OF KAOLIN & BORAX APPLICATION IN SEMI ARID REGION OF PUNJABV.S. Meena, Jitendra Singh, Poonam1 and Bharat Bhusan

Central Institute of Post Harvest Engineering and Technology, Abohar, Punjab

ABSTRACTA field trial comprising total ten treatments viz control three coloured shade nets

(Green 35% and 50%, Red & Black 50%), one insect net 50 mesh at three metre height,two evaporative cooling treatments (over tree fogger and micro sprinkler) at 2.5 meterheight and two foliar spary treatment (Kaolin 4% and Borax 0.4%) during the fruitdevelopment stage) was undertaken on pomegranate Cv. Mridula during 2012-13. Studywas aimed to evaluate the efficiency of different treatments against sunburn attack andpomegranate fruit quality under high solar radiation during summer months. Significantdifference was recorded in fruit weight and yield. No significant difference was observedin TSS (0Brix). Sun burn attack was recorded less (3.2%) in black colour shading comparedto control (9%). No significant difference was found for bacteria burnt disease in openlygrown and TSS but acidity and Vitamin-C was reduced in shadnets.
