Abstract:
A field experiment was conducted during Rabi 2014-15 and 2015-16 at BAC, Research Farm Sabour to access the effect of precession nitrogen management and tillage practices on growth parameter of wheat. The experiment was carried two tillage practices (conventional tillage, CT and Zero tillage, ZT) in main-plots and six different nutrient management practices [viz.N1-Recommended dose of nutrients (150:60:40 kg NPK/ha, full P & K and ½ N at basal +1/2N in two splitting at 1st & 2nd irrigation- Top dressing after irrigation, N2-Recommended dose of nutrients (150:60:40kg NPK/ ha, full P & K and ½ N at basal +½ N in two splitting at 1st & 2nd irrigation-Top dressing before irrigation, N3-SSNM Based on Nutrient Expert (NE), N4-70% N of SSNM based on NE+ remaining N as guided by Green Seeker, N5 Nitrogen enriched plots (225:60:40Kg. NPK/ha.) and N6-SPAD based nutrient management, (75Kg. N as basal +25Kg. N as 1st top dress +25Kg. N at 42 SPAD reading) in sub plots with 3 replications. The experimental results revealed that different tillage practices failed to exert any significant differences on growth parameter of wheat, while higher plant population were observed in conventional tillage (93.10 and 94.56m-2). Different nutrient management practices failed to exert any remarkable effect on plant population of wheat at 25 days of sowing, while maximum plant population (94.21 and 95.90 m-2) of wheat were recorded with treatment, N5 (225kg N) during rabi 2014-15 and 2015-16. Tillage practices failed to exert any significant differences on plant height of wheat during Rabi 2014-15 and 2015-16. The tallest plant of wheat was recorded in conventional tillage practices at all the growth stages of wheat, while differences was non-significant. Precession nitrogen management practices showed significant differences on plant height of plant at 60 DAS, 90 DAS and at maturity, while differences were non-significant at 30 DAS. Tallest plant of wheat was recorded with treatment N5 (225kg N) at all the growth stages of wheat during Rabi 2014-15 and 2015-16. Similar trend also follows for leaf area index (LAI) of wheat. Maximum dry matter accumulation of wheat was recorded with treatment N5 (225kg N) at 30 DAS and 60 DAS during Rabi 2014-15 and 2015-16. Whereas, higher dry matter accumulation at 90 DAS and at maturity were recorded with treatment N4 (SSNM & Green Seeker) during Rabi 2014-15 and 2015-16. Different tillage practices failed to exert any significant difference on mean crop growth rate (CGR) of wheat during Rabi 2014-15 and 2015-16. In among precession nitrogen management practices significantly higher mean CGR were recorded with treatment, N5 (225kg N) at 30-60 DAS. Whereas, higher mean CGR at 60-90 DAS were recorded with treatment, N4 (SSNM & Green Seeker).
