“…A study showed that the allelopathic compounds could be phenolic in nature (Hedberg and Edwards, 1989). Other researchers (Kahi, 2003;Humaid and Warrag, 1998) showed that P. juliflora foliage and pods contain autotoxin that can inhibit growth of other plants. However, the impact of the species on tropical food and feed crops in general and under Ethiopian condition in particular, was not studied before.…”

Phytoinhibitory effect of Prosopis juliflora aqueous extracts on tropical crops were tested under laboratory conditions. Maize, Cotton, and forage grasses (Rodus and Panicum) were used as test plants. Litter fall and under canopy soils were tested for checking allelopathic effects under natural conditions. All the extracts showed significantly negative effects on both germination and seedling growth of test crops. The effect of leaf extract was the highest, followed by litter fall, root extracts and soils respectively. However, at low concentration litter fall and root extracts showed unbalanced root growth stimulation on Zea mays, but hampered shoot growths. Since radicle growth alone cannot increase recruitment, unbalanced growth is eventually harmful to crops. Thus, we conclude that P. juliflora contains water-soluble allelochemicals capable of inhibiting tropical crops and not good for agroforestry.

“…These effects are not universal, however, and some species are more vulnerable to these chemicals than others. Specifically, the chemicals have been shown to retard the growth of Cynodon dactylon, a crucial fodder grass in Godwar (Al-Humaid and Warrag, 1998). Thus, the carpet of leaf-litter spilled yearround by the invasive babul tree removes the competitive growth of some local grasses, making way for the herbaceous species of the hardy invasive complex 4 .…”

Tracking Invasive Land Covers in India, or Why Our Landscapes Have Never Been Modern

The effects of rationalization and bureaucratization on the landscape are myriad and contradictory. The unforeseen environmental consequences resulting from modern planning create new geographies far beyond those of the planner’s design. This article explores the land‐cover effects of state‐sponsored modernization efforts in the semiarid Godwar region of Rajasthan, India. Using satellite imagery, historical data, household production information, and the discourse of state planners, the research described here explores the land covers that result from agricultural intensification, biodiversity preservation, and resource conservation in postindependence development. The study demonstrates that through these efforts, state planners have attempted to physically partition those land uses seen as “social” from those seen as “natural” and thereby enforce a modernist purification of land covers. Despite these efforts—indeed, because of them—hybrid and “impure” land covers, which mix social and natural characteristics and combine exogenous and indigenous species, have proliferated across the landscape. Moreover, these quasiforests have proven impossible to control or quarantine. The results of analysis, therefore, suggest that these sorts of unexpected land‐cover changes necessarily grow out of the very attempts to halt them through modernization, and that, despite our best efforts, following Bruno Latour, our landscapes have never been modern.

Direct Analysis in Real Time Mass Spectrometry (DART-MS) was applied to identify and study the distribution profile of piperidine alkaloids in different parts of Prosopis juliflora, without isolation and separation of the compounds by standard chromatographic techniques. With the help of DART-MS, chemical fingerprint of raw plant parts were generated, which revealed the presence of piperidine alkaloids in leaf, pod and flower. A comparative study of the distribution pattern, showed variation in the presence and distribution of these alkaloids in various parts of P. juliflora. The leaves and pod displayed the largest alkaloid pattern with a total of 12 different alkaloids in each part, whereas only 4 alkaloids were present in flower. Alkaloids: julifloridine, prosopine, prosopinine and prosafrinine were ubiquitously distributed in all the alkaloid rich plant parts. Juliprosopine was pre-eminet alkaloid in leaf, whereas pod and flower displayed copious amounts of julifloridine.
