Abstract

A field experiment was conducted at College of Agriculture, V. C. Farm, Mandya during Kharif 2021-22 to evaluate the effect of lime application for neutralizing fertilizer acidity on growth and yield of maize in Alfisols. There were eight treatments that include 500 kg lime (T3) and 250 kg granular dolomite (T4) + FYM and recommended dose of fertilizers (RDF), 100% RDF and FYM + 100 and 50% fertilizer acidity neutralization with lime (T5 and T6) and granular dolomite (T7 and T8), absolute control (T1) and FYM + 100 % RDF (T2). The experiment was laid out in Randomized Complete Block Design with three replications. The results revealed that application of lime @ equivalent to 100% neutralization of fertilizer acidity with 100% RDF and FYM (T5) recorded significantly higher plant height (221.56 cm), number of leaves (13.01 plant-1), leaf area (6389 cm2 plant-1) and total dry matter accumulation plant-1 (168.74 g plant-1) which was on par with T8, T6, T7 and T4. Similarly, significantly higher yield parameters like cob length (21.98 cm), cob girth (20.01 cm), number of rows cob-1 (16.86), number of kernels row-1 (36.98) and test weight (35.98 g) were recorded in T5 when compared to T2, T3 and T1. Kernel and stover yield (81.57 and 90.67 q ha-1, respectively) was observed to be significantly higher in T5 treatment which was on par with T6 which clearly indicated that 100% neutralization of fertilizer acidity with lime along with 100% recommended dose of fertilizer and FYM is necessary for obtaining higher growth and yield of maize.

施用石灰中和肥料酸性对阿尔菲斯土壤中玉米生长和产量的影响

2021-22 年 Kharif 期间，在 Mandya 的 V. C. 农场农业学院进行了一项田间试验，以评估施用石灰中和肥料酸性对 Alfisols 玉米生长和产量的影响。共有八个处理，包括 500 千克石灰（T3）和 250 千克粒状白云石（T4）+冻土和推荐剂量肥料（RDF）、100% RDF 和冻土+100% 和 50%肥料酸性中和石灰（T5 和 T6）和粒状白云石（T7 和 T8）、绝对对照（T1）和冻土+100% RDF（T2）。试验采用随机完全区组设计，三次重复。结果表明，施用相当于 100%中和肥料酸性的石灰（100% RDF）和青壤土（T5）可显著提高株高（221.56 厘米）、叶片数（13.01 株-1）、叶面积（6389 平方厘米-1）和总干物质积累（168.74 克-1），与 T8、T6、T7 和 T4 相当。同样，与 T2、T3 和 T1 相比，T5 的产量参数，如棒长（21.98 厘米）、棒围（20.01 厘米）、棒行数-1（16.86）、棒仁行数-1（36.98）和试验重量（35.98 克）都明显较高。据观察，T5 处理的籽粒和秸秆产量（分别为 81.57 q ha-1 和 90.67 q ha-1）明显高于 T6 处理，这清楚地表明，要获得更高的玉米生长和产量，必须用石灰中和 100%的肥料酸性，同时施用 100%的推荐剂量肥料和生土。
