<div>Background: Temperature and salinity effects on the germination and seedling growth of two subspecies of Atriplex halimus were studied in order to select the best one for the rehabilitation of degraded lands at risk of desertification. 
 
Methods: Influence of salinity levels (0, 100, 200, 300 and 400 mM) and temperature (15, 20, 25, 30 and 35&deg;C) on seed germination of two subspecies of Atriplex halimus, halimus and Schwein furthii, were assessed. Results showed optimal germination at NaCl concentration of 100 mM that decreases above 200 mM for both subspecies. In sp Schwein furthii the germination capacity is higher at NaCl concentration of 100 mM and temperatures varying between 20 and 30&deg;C. 
 
Result: High doses of salt (300 and 400 mM) strongly decrease the number of seeds germinated at all temperature regimes. In contrast, at temperatures between 30 and 35&deg;C, seed germination appears to be strongly affected in sphalimus. Salinity levels of 300 and 400 mM with temperatures of 15, 20 and 35&deg;C, reduce germination and increase mean germination time. The presence of 100 mM of NaCl in the culture medium sometimes appears to be beneficial for the growth of the seedlings. However, at high doses of salt (300 and 400 mM), length, fresh and the dry weight of the seedlings are reduced.</div>

<div style="text-align: justify;">Anthracnose of green gram caused by Colletotrichum truncatum (Schwein.) Andrus &amp; W.D. Moore occurs severely in Indo- gangetic plains every year. Experiment was conducted for two consecutive years (2013 and 2014) to assess yield losses to develop yield loss models. The linear regression models were developed by two parameters i. e. percent yield loss and avoidable yield loss as dependant variable and area under disease progress curve (AUDPC) as independent variable. The two years pooled mean revealed that a drop of 0.3 to 0.33 qha-1 in pod yield and a drop of 0.16 to 0.20% in avoidable yield loss of pod yield due to every 1% increase in AUDPC. Three sprays of Propiconazole 25 EC (0.1%) at 10 days interval beginning from 20 days after sowing resulted in lowest anthracnose under moderate disease pressure and four sprays for high disease pressure resulted in highest pod yield of 5.17q/ha and 5.08q/ha respectively. Highest avoidable losses of pod yield and percent yield loss over potential yield due to anthracnose were 48.82% and 3.55% for three sprays and 49.74% and 1.77% for four sprays respectively. The result also showed that three sprays of fungicide (Propiconazole 25 EC @ 0.1%) resulted in minimizing the disease and maximizing the profit by high benefit cost ratio (B:C) ratio.</div>
