Ludhiana, July 14, 2017: The experts of Punjab Agricultural University (PAU) have advised the farmers to not practise direct seeding of rice in light/sandy soils as there is a serious problem of iron deficiency, which results in heavy yield losses. Seed rice directly only in water logged/bet areas (where water table is not deep) with medium to heavy soils, they added.
Dr Ranvir Singh Gill, Senior Plant Breeder, disclosed, “It has been noticed that in direct seeded basmati rice crop, the attack of neck blast is more as compared to transplanted crop. The excessive use of nitrogenous fertilizers also predisposes the crop to neck blast attack.” To check the attack of neck blast, the choice of right chemical and its timely and judicious use is very important, he stressed. Dr Gill recommended the use of Amistar Top 325 SC @ 200 ml or Indofil Z 75 WP or 78 WP @ 500 gm per acre in 200 litres of water for checking the neck blast disease. The first spray should be applied at boot stage and second just before flowering, he added. The delayed application of chemicals not only proves ineffective but may pose a problem of residue in the grains, thereby, affecting the exports, he cautioned.
Dr Gill further revealed, “It has also been noticed that un-recommended basmati varieties are more prone to neck blast, as the pathogen is soil borne. It may create problem for popular basmati varieties, thereby, jeopardizing their cultivation in the state/region.” He stressed upon the farmers to cultivate only PAU recommended basmati rice varieties for sustainable basmati cultivation.
