摘要
2018年秋季,在印度贾坎德邦兰齐Birsa农业大学Dumka区域农业研究站实验农场进行了田间试验,以评估雨养中低地对土壤酸度和相关养分限制的耐受性。试验结果用粮食产量、作物对石灰的反应(%)、石灰利用效率(LUE)、作物对磷和钾的吸收来解释。试验采用分畦设计,以施肥水平(2)[氮磷钾(RD),即@ (100:50:25)kg/ha和氮磷钾(RD) +石灰@3q/ha]为主畦,水稻基因型(14)为次畦。结果表明,石灰(与品种无关)和基因型差异(与石灰水平无关)对籽粒产量和养分吸收(P和K)有显著影响。氮磷钾+石灰处理的籽粒产量(55.20 q/ha)、吸磷量(17.21kg/ha)和吸钾量(19.13kg/ha)显著提高(与品种无关)。JKRH3333和BINADHAN-75处理对石灰的响应最高(26.9%),石灰利用率最高(4.74 kg kg粒/kg石灰),BINADHAN-8和PUP-223处理对磷素和钾素的吸收分别提高了19.1%和33.0%。
Screening of rice genotypes for tolerance to soil acidity and related nutritional constraints
A field experiment was conducted in the experimental farm of Zonal Agricultural Research Station, Dumka, Birsa Agricultural University, Ranchi, Jharkhand during kharif 2018 to evaluate location specific genotypes for tolerance to soil acidity and related nutrient constraints in rainfed medium low lands. The experimental findings have been interpreted in terms of grain yield, crop response (%) to lime, lime use efficiency (LUE), P and K-uptake by the crop. The experiment was laid out in split plot design in which fertilizer levels (two) [NPK (RD) i.e., @ (100:50:25) kg/ha and NPK (RD) + lime @3q/ha] were taken as main plots and rice genotypes (fourteen) as sub-plots. It was found that the grain yield and nutrient uptakes (P & K) by the crop were significantly influenced by lime (irrespective of vars.) and genotype differences (irrespective of lime levels). Significantly higher grain yield (55.20 q/ha), P-uptake (17.21kg/ha) and K-uptake (19.13kg/ha) were recorded with (NPK + Lime) (irrespective of vars.). The highest crop response to lime (26.9%) and lime use efficiency (4.74 kg grain /kg lime) were recorded with JKRH3333 and BINADHAN-75, respectively, whereas the maximum increase in P-uptake (19.1%) and K-uptake (33.0%) were obtained with BINADHAN-8 and PUP-223, respectively.
