Performance of different paddy varieties

Sirusuwada of Kothuru (mandal), Srikakulam (Dist) flood prone village under NICRA project. Here climatic is very erratic. Some times flood immediately follows by drought. Paddy is the main crop and farmers are growing varieties like BPT 5204, SWARNA, MTU 1001 which are susceptible to flooding although have high yield potential and market demand in the district. KVK Srikakulam has demonstrated paddy varieties PLA 1100, RGL 2537 and Indra in 14 farmers’ fields covering 5.4 hectares. Merits and demerits of demo varieties are:



PLA 1100 :

Fine grain, crop duration 160 days, suitable for low lying inundated areas and tolerant to flood at any stage of crop growth. However, sprouting of grains occur if prolonged rain coincides with harvesting, the variety is of shattering type.

RGL 2537 (Srikakulam Sannalu) :

Suitable for late planting situation with over aged seedlings, also able to tolerate short period of inundation (4-5 days), but not for prolonged inundation.  Fine grain variety with crop duration of 165 days.

MTU 1061 (Indra): This is also flood tolerant non-lodging, fine grain variety with crop duration of 150 days. It has got dormancy of 2-3 weeks. It can tolerate inundation up to 10 days only at later stages of crop growth but not during early stage.

 

There was heavy rainfall at different crop growth stages and details are mentoned below in the table:
