Abstract:

A field experiment was conducted during kharif seasons of 2012 and 2013 at KVK Thoubal, Manipur to assess the effect of different levels of sulphur and zinc on yield of kharif rice (Oryza sativa L).The treatments consisted of four levels of suphur (0, 15, 20 and 25 kg/ha) and four levels of zinc (0, 5, 10 and 15 kg Zn/ha) laid out in factorial randomise block design and which were replicated thrice. Application of 20 kg S/ha recorded highest number of effective tillers/m2 (233.99), filled grains/panicle (100.95), grain yield (56.3 q/ha), straw yield (64.8 q/ha) and harvest index (46.27%) over the remaining treatment. Regarding test weight also 20 kg S /ha recorded the highest value and least with control (0 kg S/ha). Application of 15 kg Zn/ha recorded highest number of effective tillers/m2 (237.34), number of filled grains/panicle (99.21), test weight (23.63g), grain yield (55.90 q/ha), straw yield (64.70 q/ha) and harvest index (40.06%), but it was statistically at par with the 10 kg Zn/ha. Significant interaction effect of sulphur and zinc on number of tillers per m2 of rice was observed in both the years and at pooled with the highest value was observed at S20Zn15 (265.70) but remained at par with S15Zn15. Significant interaction effect of sulphur and zinc on rice was observed in both years and in pooled mean with highest value of 67.6 q/ha and 71.70 q/ha in S20Zn15 for grain yield and straw yield respectively. But this treatment remains at par with S15Zn15 and S20Zn10 for straw yield. Regarding harvest index also, S20Zn15 recorded significantly highest value (48.53%). Regarding the net return highest value was observed at S20 Zn15 (Rs 29278.38), however highest B: C ratio was recorded with the treatment combination of S20 and Zn5 (0.63).
