Phenological Traits of Rice as Influenced by Seedling Age and Number of Seedling Per Hill under Temperate Region

The research study “phonological traits of rice crop as influenced by seedling age and number of seedling per hill in temperate zone” was conducted at Agricultural Research Institute (N) Mingora, Swat, Khyber Pakhtunkhwa, Pakistan, during summer 2014. Rice was transplanted at three different seedling ages 20, 25 and 30 days after sowing and with various number (1, 2 and 3) of seedlings hill-1. The experiment was conducted using Randomized Complete Block Design (RCBD) with split plot arrangement having four replications. Seedlings age were kept in main plot while number of seedlings hill-1 in sub plot. NPK was applied at the rate of 120:60:40 kg ha-1 respectively. Data was recorded on flag leaf area plant-1 (cm2), number of tillers hill-1, plant height (cm), panicle length (cm), number of primary branches panicle-1 and number of secondary branches panicle-1, All the parameters were significantly affected by seedlings age and number of seedlings hill-1. Maximum flag leaf area plant-1 (22.26 cm2) was observed at seedling age 25 days after sowing, more number of tillers hill-1 (17), higher plant height (100.16 cm), higher panicle length (29 cm), more number of primary and secondary branches panicle-1 (12, 37), Maximum flag leaf area plant-1 (22.47 cm2), more number of tillers hill-1 (18), higher plant height (100.27), higher panicle length (29 cm), more number of primary and secondary branches panicle-1 (12, 38). It was concluded on the basis of above results that phonology of rice crop influenced by seedling age and number of seedling hill-1under temperate region
