Response of mustard and linseed to thermal power plant wastewater supplemented with nitrogen and phosphorus

  The effect of thermal power plant discharged waste water (TPPW) on growth, yield and quality of mustard (Brassica juncea L. cv. Alankar) and linseed (Linum usitatissimum L. cv. Neelam) was studied. TPPW increased growth characteristics, net photosynthetic rate, seed yield, oil content and oil yield of the two crops. In mustard, treatments TPPW N112P60 (112 kg N/ha + 60 kg P/ha), TPPW N112P30 (112 kg...

Induction of anti-oxidative enzymes by cadmium stress in tomato (Lycopersicon esculentum)

  In the present study, the cadmium’s effect on anti-oxidative enzymes in tomato (Lycopersicon esculentum) plants was evaluated. Plants treated with increasingly CdCl2concentrations (0, 20, 40, 80, 100 and 200 μM respectively) were grown in a basic nutrient solution for 7 days. APX (Ascorbate Peroxidase) and GPX (Guaïgol Peroxidase) activities showed to increase below 100 μM concentration after...

Morphological and agronomical characterization of sweet potato [Ipomoea batatas (L.) Lam.] germplasm collection from Tanzania

  One hundred and thirty six sweet potato (Ipomoea batatas) landraces collected from three different agro-ecological Zones of Tanzania [Lake Victoria basin (LZ), Eastern (EZ) and Southern Highlands Zones (SHZ)] were characterized morphologically and agronomically using International Potato Centre (CIP) descriptors in two seasons. The cluster analysis revealed existence of two major groups, 1 and 2...
