“…These claims are a clear contradiction that warrants investigation for a definitive perspective on the link between row planting and xenobiotic use. Devi et al (2018) and Mahajan et al (2019) offer empirical precedent of association between row planting and xenobiotic use. Althother, these factors are considered within a package of farming innovation .…”

To settle inconsistent findings in the farming innovation and productivity nexus, this inquiry examines the land management practices of 7,625 households in rural Ethiopia. Specifically, the net effects of (1) improved seeds, (2) mixed cropping and (3) row planting on the use of (4) pesticides, (5) herbicides and (6) fungicides are assessed. Using a structural equation technique, the study probes how these six practices predict households' expected harvest. It is found that while improved seeds increase pesticide, herbicide and fungicide use, mixed cropping and row planting generally reduce these practices. Moreover, mixed cropping moderately increases expected harvest while improved seeds and row planting have the reverse effect. The interrelations of these factors increase knowledge in contingency-driven agronomics, and provoke reflection on the sustainability of land management practices. Particularly, opposed to prevailing views, it is demonstrated that sowing traditional seeds will reduce households' reliance on pesticides, herbicides and fungicides. The inherent findings speak to policy-makers tasked with supporting peasant life in rural Ethiopia and similar contexts.

“…The number of market entry of herbicides with new mode of action has reduced. For effective management of complex weed flora, there is need to use mixture of existing herbicides (Devi et al, 2017a), which should have a wide spectrum of weed control without crop injury and residual effect on succeeding sensitive crops and can enhance the productivity of crop (Devi et al, 2017b). Every (crop) plant has a definite temperature requirement for attaining certain phonological stages.…”

“…It is considered a noxious weed in grain, vegetable and oilseed crop's fields like wheat, mustard, pea, chickpea, fenugreek, berseem, lucerne, potato, oat etc. (Devi et al 2018b). Along with other winter weeds, Melilotus species caused more than 45% yield losses in winter season crops.…”

Influence of environmental factors on germination and seedling emergence of Melilotus indicus

et al. 2020

To find out the effect of temperature, osmotic stress, light, pH, salt stress, burial depth, mulching and flooding duration on seed germination and seedling emergence of Melilotus indicus, laboratory and screen house experiments were conducted at CCSHAU, Hisar, during rabi seasons of 2015-16 and 2016-17. All the experiments were conducted in a completely randomized design with each treatment having four replications. Based on research results, it was observed that the optimum temperature range for the germination of M. indicus was 15-30oC day temperature and 10-20oC night temperature. It was more sensitive to moisture stress, as its seed germination decreased from 95% to 38% with increasing moisture stress (from 0 to -1.2 MPa), whereas it was less sensitive to salt stress: as more than 50% seed germination occurred at 125 mM NaCl salt concentration. The optimum pH for its seed germination (90%) was neutral (pH 7). It was non-photoblastic in nature, as dark and light period had no significant effect on its seed germination. The optimum burial depth for higher seedling emergence was 1 cm (>90%), but its emergence decreased as burial depth increased further. The seedling emergence was reduced by the application of rice straw as mulch, though a high amount (4 to 10 t/ha) of straw was required to suppress its emergence significantly. Continuous flooding for different durations significantly reduced the seedling emergence of M. indicus over no-flooding condition, and was not able to emerge after 32 days of continuous flooding. The information gained from this study would help in developing effective weed management strategy against M. indicus.
