ABSTRACT

Deficiency of macro and micro nutrients, especially phosphorus (P) and boron (B), reduce french bean growth, productivity, and ultimately nutrient bio-fortification, and ultimately effects human and livestock health. Limited supplies of P reduces roots growth, development, elongation and ultimately nutrients uptake while B deficiency cause faintness in plant defensive mechanism and grain development in cereal and legumes. Application of B in combination with P act as a bio-stimulant which improves biological and chemo-physical properties of the soil. Experiments were conducted to determine the effect of P and B application on the yield and yield component of french bean in the far-flung hilly area of different elevation (Madyan and Behrain) during summer 2012 to 2014. French bean variety “Paulista” was sown on a well-prepared clay loam soil. The effect of phosphorus was significantly (P < .05) increased bean yield and growth parameters such as phosphorus concentration in french bean, number of plants m⁻², plant height (cm), number of leaves plant⁻¹, number of pods plant⁻¹, number of seeds plant⁻¹, pods length (cm), thousand seeds weight (g), seed yield (kg ha⁻¹) bean yield and harvest index (%). Combine effect of P and B was found significant for number of plants m⁻², plant height (cm), number of leaves plant⁻¹, pods length (cm), numbers of seeds pod⁻¹, number of pods plants⁻¹, thousand seed weight, seed yield and harvest index. Based on results obtained from this experiment, application of 80 kg P ha⁻¹ and 12 kg boron ha⁻¹ application is recommended for better production of haricot bean.

摘要

宏观和微量营养素的缺乏，尤其是磷 (P) 和硼 (B)，会降低法国豆的生长、生产力，并最终影响营养生物强化，并最终影响人类和牲畜的健康。有限的磷供应会降低根系的生长、发育、伸长和最终的养分吸收，而 B 缺乏会导致植物防御机制和谷物和豆类的谷物发育减弱。将 B 与 P 结合用作生物刺激剂，可改善土壤的生物和化学物理特性。2012-2014年夏季，在不同海拔的偏远丘陵区（Madyan和Behrain），通过施磷和B施磷对法国豆产量和产量构成的影响进行了试验。种植了法国豆品种“保利斯塔”。在准备好的黏壤土上。P < .05) 增加豆类产量和生长参数，例如法国豆中的磷浓度、植株数 m ^-2、植株高度 (cm)、植株叶数^-1、豆荚植株数^-1、种子植株数^-1，豆荚长度（cm），千粒重（g），种子产量（kg ha ^-1）豆产量和收获指数（%）。发现 P 和 B 的组合效应对植株数 m ^-2、植株高度 (cm)、植株叶数^-1、豆荚长度 (cm)、种子荚数^-1、豆荚植株数^{-1 显着}、千粒重、种子产量和收获指数。根据从该实验获得的结果，建议施用 80 kg P ha ^-1和 12 kg 硼 ha ^-1以更好地生产扁豆。
