Composition and diversity of soil macrofauna in
saffron fields of Pampore, Kashmir
Abroo Ali and GA Bhat
Abstract
Saffron (Crocus sativus L.) has a significant place in agricultural economy of Kashmir, but it has
remained under exploited and unrefined and needs to be managed to increase and sustain its yield. This
study assessed the diversity and composition of macrofauna and effect of intercropping on the same.
Macro fauna was sampled in transects, for which the ideal size was 40 x 4m in accordance to Anderson
and Ingram (1993)
[4]
. During the study a total of 33 taxa, belonging to 19 families, 9 orders, 5 classes
and 2 phyla were recorded. Amid the entire developing season, Shannon wiener index of 0.99 ± 0.05 was
recorded for the macro faunal community of the study area. The area was found to be more diverse in
terms of genera belonging to order Coleoptera with a diversity index of 0.76 ± 0.13. Results additionally
pointed almond intercropping in saffron field did not conspicuously affect the diversity and the
composition of soil macrofauna. As no examination in such manner has been directed, it will go about as
basic and standard information for future investigations to help decision makers and managers to take
wise choices while dealing the saffron agro frameworks, to maintain them.

Introduction
Saffron (Crocus sativus L.) has a significant place in agricultural economy of Kashmir as it is
the most noteworthy estimated flavor and highly priced spice in the world. As revealed by
Kamili and Wani (2006)
[25]
, the crop has remained under exploited and unrefined. The
intensive cultivation and monoculture of saffron in saffron-growing belts of the Kashmir
valley is prompting to nutrient depletion and pest infestations reported in many investigations
(Nehvi, 2003; Zaki and Mantoo, 2008; Kirmani, 2010)
[35, 52]
. What is more, disappointment in
irrigation system at time of growing season has expanded the input costs in development of the
yield (Munshi et al., 2002; Kirmani, 2010; Nehvi and Makhdoomi, 2007b)
[33]
. This has
brought about the region under saffron development from past years. This investigation was an
endeavor to investigate the impacts of intercropping almond in the saffron fields.
Monocultures are a case of agro biological systems with low diversity and might be more
susceptible to pest or disease outbreaks (Theunissen, 1994; Rusch et al., 2016)
[46, 42]
. Perennial
plants intercropped with yearly harvests, can enhance the sustainability of those cropping
systems which support low diversity agro ecosystems. Biodiversity conservation in
agricultural ecosystems is of growing concern, since it is essential to support and sustain
ecosystem services (Altieri, 1999; Norris, 2008)
[2, 36]
.
Bioindication exists as a valued tool, as it empowers the appraisal of protection of an
ecosystem in light of the living organisms that it comprises. Soil macro fauna specifically, has
been seen to express as delicate markers to modifications in plant cover (Lavelle and
Pashanasi, 1989; Mathieu et al., 2005; Sileshi et al., 2008)
[28, 32, 43]
and can, thus, have
considerable impacts on soil processes. A few investigations utilized arthropods as
bioindicators, generally pointing on a particular group. For some arthropods, survival in
agrosystems relies upon the suitability of the habitat, which in turn is sturdily affected by
agricultural management, along with the characteristics of the surrounding landscape
(Jeanneret et al., 2003)
[23]
. Many authors have proposed the deployment of higher taxonomic
levels, such as order or family in addition to lower (Balmford et al., 1996; Biaggini et al.,
2007; Cotes et al., 2011)
[7, 9, 13]
, to develop bioindication methods. Most farming practices are
detrimental having effect on the Soil macro fauna. Cover crops can turn out to be a noteworthy
way of conserving beneficial insects and
