摘要

2011-12年和2012-13年，在正在进行的全印度协调研究项目下，在2006-07年开始在Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani (ms)进行的大豆-红花长期施肥试验(典型haplusterts)中进行的一项试验表明，FYM和100% NPK施用对土壤养分有效性、养分吸收、产量属性和大豆产量都有显著影响。结果表明，100% NPK+ fym@5mg ha-1处理显著提高了大豆单株荚果(48.65个)、株高(49.77 cm)、籽粒(26.97 q ha-1)和秸秆(24.65 q ha-1)产量。与初始值相比，FYM与100% NPK联合施用改善了土壤的容重、有机碳、交换性(Ca、Mg、Na和K)、阳离子交换容量(CEC)、碱饱和度(BS)、有效N、P、K、S、Zn和Fe。然而，与所有其他处理相比，硫酸锌与100%氮磷钾的施用显著增加了有效锌。100% NPK+FYM@ 5 Mg ha 1处理显著提高了大豆对N、P、K、S、Zn和Fe的吸收。从这些试验中可以得出结论，化肥的连续平衡使用，无论是单独使用还是与有机肥结合使用，都是保持土壤肥力和作物生产力的必要条件。

Impact of Long-term fertilizer application on soil fertility, nutrient uptake, growth and productivity of soybean under soybean-safflower cropping sequence in Vertisol

An experiment conducted during 2011-12 and 2012-13 under the ongoing All India Coordinated Research Project on Long-Term Fertilizer Experiment with soybean-safflower cropping sequence in Vertisol (Typic haplusterts) that commenced form 2006-07 at Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani (M.S.) showed that the nutrients availability in soil, nutrient uptake, yield attributes and yield of soybean were significantly influenced by FYM along with 100% NPK application. The results revealed that the pods per plant (48.65), plant height (49.77 cm plant-1), grain (26.97 q ha-1) and straw (24.65 q ha-1) yield of soybean were significantly increased with 100% NPK+FYM@ 5 Mg ha-1. Conjoint use of FYM with 100% NPK improved the soil properties with respect to bulk density, organic carbon, exchangeable (Ca, Mg, Na & K), cation exchange capacity (CEC), base saturation (BS), available N, P, K, S, Zn and Fe over initial value of soil. However, a significant buildup of available Zn due to the application of zinc sulphate along with 100% NPK as compared to all other treatments. N, P, K, S, Zn and Fe uptake of soybean were increased significantly with the application of 100 % NPK+FYM@ 5 Mg ha 1 than other treatment. It can be concluded from these experiment that the balanced use of fertilizers continuously either alone or in combination with organic manure is necessary for sustaining soil fertility and productivity of crop.
