ABSTRACT

Field experiments were conducted to study the effect of calcium (Ca), Boron (B) and their combination, i.e., 0, (0.03%Ca), (0.06%Ca), (0.02%B), (0.04%B), (0.03%Ca) + (0.02%B), (0.03%Ca) + (0.04%B), (0.06%Ca) + (0.02%B) and (0.06%Ca) + (0.04% B) on production and quality of autumn potato crop. Results revealed that different sowing dates, Ca, B treatments and their interaction significantly affected yield and quality parameters of potato crop. The application of Ca alone @ 0.06% significantly increased the large tubers plant−1 (2.0), total yield (18.6 t ha−1), survival (78%), dry matter content (18.3%) and starch content (14.6%) as compared to control treatment. Boron @ 0.04% also significantly enhanced large tubers plant−1 (2.1), total yield (18.7 t ha−1), survival (75%), dry matter content (18.2%) and starch content (14.9%) than control treatment. Foliar application of (0.06% Ca) + (0.02% B) resulted in the maximum number of large tubers plant−1 (2.5), total yield (20.5 t ha−1), dry matter content (19.5%) and starch content (16.2%) as compared to other treatment combination. Plant survival was maximum at (0.06% Ca) + (0.04% B). Increasing Ca, B concentration decreased in number of small size tubers plant−1. Early sown potato plants with the combined application of 0.06% Ca + 0.02% B resulted in maximum yield and quality characteristics as compared to the rest. So it is concluded that early planting in the first week of October with the combined application of 0.06% Ca + 0.02% B resulted in maximum yield and quality of potato.

低温下钙和硼对秋马铃薯产量和品质的影响

摘要

进行了野外实验以研究钙(Ca),硼(B)及其组合(即0,(0.03%Ca),(0.06%Ca),(0.02%B),(0.04%B), (0.03%Ca)+(0.02%B),(0.03%Ca)+(0.04%B),(0.06%Ca)+(0.02%B)和(0.06%Ca)+(0.04%B)秋季马铃薯的品质。结果表明,不同的播种日期,Ca,B处理及其相互作用均显着影响马铃薯作物的产量和品质参数。仅以0.06%的比例施用Ca可以显着提高大型块茎植物-1(2.0),总产量(18.6 t ha -1),存活率(78%),干物质含量(18.3%)和淀粉含量(14.6%)与对照治疗相比。硼@ 0.04%也显着增强了大型块茎植物-1(2.1),总产量(18.7吨公顷)-1),存活率(75%),干物质含量(18.2%)和淀粉含量(14.9%)比对照处理高。叶面施用(0.06%Ca)+(0.02%B)导致大型块茎植物-1(2.5)的最大数量,总产量(20.5 t ha -1),干物质含量(19.5%)和淀粉含量(与其他治疗组合相比为16.2%)。在(0.06%Ca)+(0.04%B)下,植物存活率最高。小型块茎植物-1的Ca,B浓度增加。与其余部分相比,早播马铃薯植株与0.06%Ca + 0.02%B的组合施用可获得最大的产量和品质特征。因此可以得出结论,在10月的第一个星期进行早播并结合使用0.06%Ca + 0.02%B可以使马铃薯的最高产量和品质达到最高。
