Abstract


A field experiment was conducted at Tamil Nadu Agricultural University, Coimbatore during late Samba season (2017-18) to study the effect of varieties and methods of planting on productivity of organic rice. The experiment was laid out in split plot design with three replications. Four varieties (V1 - Rice CO-52, V2 - Jeeraga samba, V3 - Kitchili samba and V4 - Improved white ponni) were grown in main plot and three planting methods (P1 - Random planting, P2 - Line planting and P3 - SRI method) were allotted to sub-plots. The experimental results revealed that Rice CO-52 registered lesser plant height (113.2 cm), higher drymatter (10330 kg/ha), LAI (4.70), total number of tillers (441/m2), number of productive tillers (394/m2), total number of grains and filled grains, grain yield (3780 kg/ha) and harvesting index. Among methods of planting, SRI method of planting registered higher growth characters, yield attributes and yield of rice than other methods of planting. Hence, it is inferred that SRI method enhanced productivity of rice under organic farming.
Key words: Organic farming, Traditional rice, Planting methods, Performance of rice.

to increase the postharvest life. AIB is an ethylene biosynthesis inhibitor which inhibits the ethylene synthesis by inhibiting ACC oxidase enzyme. Banana fruits were treated with different AIB concentrations (50, 100, 150, 200 ppm along with control) and spraying methods (Dipping and Spraying). AIB @ 150 ppm dipped for 5 minutes showed decreased finger dislodge from the hands (50-70 per cent at 11th day after treatment) compared to control fruits (100 per cent at 9th day after treatment). On comparing AIB with ethylene inhibitor (1-MCP) and chemicals (Hexanal and calcium chloride) under cold and ambient storage condition, AIB showed better result with reduced finger drop. At 11th day of cold storage AIB treated fruits exhibited minimum finger drop of 50 per cent followed by 1-MCP vaporization with finger drop percentage of 60 and control fruits reported the maximum number of finger drop (90 per cent). Under ambient condition at 7th day itself the AIB treated fruits showed 60 per cent finger drop. Hence from the present study, the external temperature would alter the storage life of the fruits which may be an important factor and noted for further improvement of postharvest life of fruits by storing under required temperatures and minimizing the postharvest losses.

Key words : : Weak neck, α- Amino isobutyric acid, Storage condition.
