摘要

在2019- 2020年拉比季节,在Jaunpur (up) Tilak Dhari研究生院农学系农业研究农场(Pili Kothi)的沙质壤土上进行了田间试验。试验由2个因素组成,即:(1)两种种子率分别为120和140 kg/ha;(2) 4种养分,即(i) 100% RDF, (ii) 125% RDF, (iii) 75% RDF +25% N - FYM和(iv) 75% RDF +25% N - VC。品种HD-3118对小麦的生长性状有显著影响。最大记录生长性状为株高87.11cm,分蘖数592.32 m2,干物质积累量1010.01gm2,叶面积指数3.38。记录的最小生长性状为株高81.81cm,分蘖数542.57 m2,干物质积累量980.90gm2,叶面积指数3.13。因此,在12月23日播种时,可施用125% RDF和140 kg/ha-1的种子率,以实现小麦作物生长最大化。

Effect of seed rate and nutrient management on growth of wheat under late sown condition
A field experiment was conducted during rabi season of 2019-20 on sandy loam soil at Agricultural Research Farm (Pili Kothi), Department of Agronomy, Tilak Dhari Post Graduate College, Jaunpur (U.P.). The experiment comprised of two factors namely (1) two seed rate viz.120 and 140 kg/ha-1 (2) four nutrient namely (i) 100% RDF, (ii) 125% RDF (iii) 75% RDF +25% N through FYM and (iv) 75% RDF +25% N through VC In RBD design with eight treatment and four replication. Variety HD-3118 recorded significantly influenced the growth characters of wheat crop. The maximum recorded growth character are as follows, plant height (87.11cm), number of tillers (592.32 m2), dry matter accumulation (1010.01gm2) and leaf area index (3.38). And minimum growth character was recorded are as follows, plant height (81.81cm), number of tillers (542.57 m2), dry matter accumulation (980.90gm2) and leaf area index (3.13). Thus sowing on 23 December, 125% RDF and 140 kg/ha-1 seed rate can be practiced for maximizing of growth of wheat crop.
