Experiment was conducted at agronomy rsearch field, SKUAST-K, Main Campus, shalimar srinagar (J&K), India in
kharif 2005 and 2006. Experiment was laid out in Split-Split Plot design with treatment of two irrigation : I1 = assured irrigation and I2 = at disappearance of water and development of hair cracks in soil, two age of seedling : A1 = 20 days old and A2 = 40 days old, and in sub plot assign four plant spacing : S1 = 20x15 cm, S2 = 25x15 cm, S3 = 20x20 cm & S4 = 40x10 cm.Temperate climate prevails at experimental site.
Results :
Effect of irrigation: It is revealed from the results (Table: 1) that application of water at disappearance of water and development of hair cracks in the soil found statistically significant for number of grains per panicle and seed yield (qha-1) over the assured irrigation (i.e. pounded water round the season). The similar treatment was remained at par for number of tillers/panicle, grains/panicle, panicle length, test weight (g) and straw yield (qha-1).
Effect of the age of seedling: Transplanting of 20 days old seedling proved superior over 40 days old seedling for the number of tillers/hill panicle length, seed and straw yield (q ha-1). Contrary to this, number of grains/panicle and test weight (g) did not show significant difference for the age of seedling.Effect of spacing: Significantly higher seed and straw yield was recorded under a hill spacing of 20X15 over 20X20, 25X15, and 40X10, whereas, the difference was not significant for number of tillers, grains/panicle, panicle length and test weight (g).
Conclusion :
Application of water at disappearance of ponded water and development of hair cracks in the soil was found more effective and economic over the assured irrigation (i.e. ponded water round the season). Transplanting of 20 days old seedling prooved superior over 40 days old seedling.
