Abstract

: Integrated nutrient management (INM) is an environment friendly and ecologically adoptable approach of plant nutrition to sustain crop productivity and maintain soil fertility of fragile agricultural ecosystems. A three-year field experiment on saffron was conducted involving 12 fertilization regimes: control; urea (UN) = 100 kg · ha -1 ; poultry manure (PM) = 100 kg · ha -1 ; farmyard manure (FYM) = 100 kg · ha -1 ; PM 50 + FYM 50 ; UN 75 + PM 25 ; UN 50 + PM 50 ; UN 25 + PM 75 ; UN 75 + FYM 25 ; UN 50 + FYM 50 ; UN 25 + FYM 75 ; and UN 50 + PM 25 + FYM 25 . Results showed that PM alone and combined with 50% UN (UN 50 + PM 50 ) were effective compared to the controls in increasing the number of flowers (58%), flower dry weight (59%), stigma length (70%), dry weight of stigma (40%), number of daughter corms plant -1 (35%), and corm diameter (71%) of saffron over years. In addition, the same treatment combination increased corm weight (96%), corm yield (96%), and stigma yield (35%) over controls across the years. This treatment combination was followed by UN 50 + PM 25 + FYM 25 , while UN 50 alone did not perform at par to the rest of the fertilization regimes. These results showed that UN 50 + PM 50 might be developed as potent strategy for boosting the growth and yield (stigma and daughter corms yield) of saffron in temperate climatic conditions.
有机矿施肥对温带藏红花生长和柱头产量的影响
综合营养管理(INM)是一种环境友好和生态上可采用的植物营养方法,以维持脆弱的农业生态系统的作物生产力和土壤肥力。对藏红花进行了为期三年的田间试验,涉及12种施肥方案:对照;尿素(UN) = 100 kg·ha -1;禽粪(PM) = 100 kg·ha -1;农家肥= 100 kg·ha -1;PM 50 + fym 50;联合国75 + PM 25;UN 50 + PM 50;UN 25 + PM 75;联合国75 + fym 25;UN 50 + fym 50;UN 25 + fym 75;联合国50 + PM 25 + FYM 25。结果表明,与对照相比,PM单独施用或与50% UN (UN 50 + PM 50)联合施用可有效提高藏红花花数(58%)、花干重(59%)、柱头长(70%)、柱头干重(40%)、子球茎数(35%)和球茎直径(71%)。此外,多年来,相同的处理组合比对照增加了球粒重(96%)、球粒产量(96%)和柱头产量(35%)。在此处理组合之后是UN 50 + PM 25 + FYM 25,而UN 50单独施用的效果不如其他施肥方案。这些结果表明,在温带气候条件下,UN 50 + PM 50可以作为促进藏红花生长和产量(柱头和子粒产量)的有效策略。
