“…Signi cantly higher levels of ascorbic acid content in garden pea could be due to increased accumulation of carbohydrates and conversion of more organic acids into sugars with sludge doses. Similar ndings were reported by (Aminifard et al, 2012;Dhotre et al (2018).…”

The productivity of plants is a direct variant of the countless biotic and abiotic stresses to which a plant is exposed in an environment. This study aimed to investigate the capabilities of leguminous plant garden pea (Pisum sativum L.) to resist water de cit conditions in arid and semi-arid areas when applied with varied doses of sludge for growth response. The effect of sludge doses was evaluated on crop yield, antioxidant enzymes viz., ascorbate peroxidase APX, dehydroascorbate reductase (DHAR), superoxide dismutase (SOD), glutathione reductase (GR) and metabolites (ascorbic acid, glutathione and total protein content). The effective sludge concentrations with respect to seed weight and crop yield were found to be in the following trend: D 2 (6.25%) > D 3 (12.5%) > D 1 (2.5%) > D 0 (control) under organic amendment (OA). Conversely, a high dose of the sludge reduced the seed weight and total crop yield. The sludge doses D 2 under arid and semi-arid conditions along with organic amendments (OA) signi cantly enhance the antioxidant enzyme activity whereas, sludge dose D 3 with OA ominously regulates the activity of these enzymes. Besides, seeds depicted a considerable increase in ascorbic acid, glutathione and total protein content in arid and semi-arid conditions upon the application of sludge with OA. Sewage sludge as a source of nutrients indirectly enhances crop yield, antioxidant enzymes and antioxidant metabolites. Thus, it improves the defence mechanism, reduces abnormal protein glycation, and depletes susceptibility of protein to proteolysis.

“…Fertigation has also been widely used, but salinization is a risk mainly caused by salt fertilizers, which negatively affects seed germination (Maciel et al, 2012). Dhotre et al (2018) concluded that the combination of irrigation replenishment at 60% of ETc and fertigation with 75% recommended fertilizer dose was optimal to obtain higher bell pepper yields and better fruit quality. ------------------------Germination (%)------------------------ According to Sheldon et al (2017), the seeds of a salt-sensitive plant at higher salinities has the NaCl toxicity as the dominant factor, which consequently reduces the seed water use capacity due to the low osmotic potential of the salty soil solution.…”

Bell pepper (Capsicum annuum L.) is the third most cultivated Solanaceae species in Brazil and is highly sensitive to osmotic stresses. The increasing soil salinity is a frequent problem that hinders the plant absorption of water and nutrients by the roots, limiting agricultural production. Therefore, this study’s objectives were to evaluate the germination, vigor, and development of bell pepper commercial cultivars after NaCl treatments to simulate osmotic stress. Five cultivars (Yolo wonder, SF134 yellow, Marta, All big red, Cascadura) were submitted to four osmotic potentials (salt stresses of 0, -0.3, -0.6, -0.9 MPa) in a factorial scheme of 5×4, with four repetitions. The results indicated that the bell pepper germination is highly affected according to the presence of NaCl. The bell pepper germination supports NaCl concentrations equal to or higher than -0.3 MPa osmotic potential. Significant reductions in germination, germination speed index, seedling length, and dry mass as the salinity increases - osmotic potential decrease. The yellow bell pepper ‘SF134’ presented similar germination down to -0.6 MPa and can be cultivated in regions with salinity problems. The green bell pepper ‘Cascadura’ presented great germination, germination speed index and dry mass, and superior seedling length, being indicated for cultivation in more diverse environments.

A field experiment aimed to study the response of deficit irrigation water under both traditional and drip irrigation systems combined with soil amendments, on yield and quality. The experiment tested 30 treatments arranged in strip split plot design. The horizontal plots were allocated to the irrigation systems (surface and drip irrigation), whereas the vertical plots were devoted to the irrigation regimes of 40, 60 and 80% of the irrigation water requirement (IWR), while the sub plots were included five soil amendments (without, 250, 500 kg.fed -1 potassium silicate ore and 35, 70kg.fed -1 potassium humate). The results showed that the drip irrigation system produced significantly higher values of No. of flowers/plant, fruit setting %, early yield, total fruit yield and total seed yield per fed. compared to surface irrigation system. Results indicated that significantly highest values were recorded from the irrigation regime at 80% following irrigation at 60 % of the irrigation water requirement (IWR). Results also showed that, the higher values were obtained from soil amendments at 70 kg/fed from potassium humate following with 500 kg/fed from potassium silicate. In addition, the results showed that a higher average for all the above parameters were obtained from soil amendments at 70 kg/fed from potassium humate following with 500 kg/fed from potassium silicate under drip irrigation system at 80% (6922 m 3 /fed.) following irrigation at 60% of IWR (5192 m 3 /fed.). Finally, we recommend this treatment because it saves water irrigation (4091and 5821 m 3 /fed. respectively) and obtains the best yield with improved quality of pepper fruits.
