“…The efficacy of potassium nitrate on the seedling height of horned melon, with 2.5 % KNO 3 recording the highest, could be attributed to nitrogen in potassium nitrate, which induces and speeds vegetative growth. The results from this study agree with the findings of Oliveira and Steiner [43] in an experiment on cucumber seed priming. The hypocotyl length rose from 59.0 to 62.8 mm when the seeds were primed with KNO 3 .…”

The horned melon (Cucumis metuliferus) is mostly grown in tropical and subtropical countries, where it thrives on deep to shallow, well-drained soils. Seed dormancy, which causes poor and delayed germination, has remained a problem for farmers in several African countries, including Zimbabwe, who have begun producing horned melon. Midlands State University conducted a laboratory experiment to evaluate the effects of potassium nitrate on seed germination and early seedling growth of horned melon. The experiment was set up in a Completely Random Design (CRD) with seven different potassium nitrate (KNO3) concentrations (0 %, 0.5 %, 1.0 %, 1.5 %, 2.0 %, 2.5 %, and 3.0 %), each duplicated three times. The data was analyzed using a one-way Analysis of Variance (ANOVA) in Genstat 18th edition. The characteristics of germination and early seedling development were assessed. All germination and early seedling development characteristics were significantly affected by potassium nitrate. Germination %, mean germination rate, germination index, mean daily germination percent, synchronization of germination, peak value for germination, and germination value all had a significant influence. Potassium nitrate had a significant influence on mean germination time and time to 50 % germination, with the lowest values obtained on seeds primed with 3 % KNO3. There was a significant difference in seedling height, root length, seedling length, fresh biomass, and dry weight between seeds primed with 2.5 % KNO3 and seeds not primed with 2.5 % KNO3. Farmers are advised to use 2.5 % KNO3 concentration for seed priming for optimal germination and early plant development of horned melon

“…For instance, the seed germination, emergence rate and growth of young seedlings of sugar beet (Beta vulgaris L.) [19,20], Phaseolus mungo [21] and Dianthus chinensis L. [22] decreased by NaCl treatments. Quantitatively, the salinity condition decreased the seed germination of nut (atropha curcas L.) by 50% [23], coriander (Coriandrum Sativum L.) by 65.67%, cultivar Kalmiand Pant Haritma by 55.56% [24], oat (Avena sativa L.) by 60.87% [25] etc. Berseem clover (Trifolium alexandrinum L.) is one of the best forage sources for feeding live stock and is considered as anon-bloating and high-quality forage [26].…”

Developing seeds with a high level of tolerance against salinity and water shortage scan guarantee best seedling establishment in arid and semi-arid agricultural lands. This three-year field, laboratory and greenhouse study proposes the surfactant application to effectively prevent the detrimental impacts of severe environmental conditions on the development of parental plants. The germination rate of six parental seeds of berseem clovers (Trifolium alexandrinum L.) from I 100 (100% irrigation water)/I 100 +s (irrigation water with surfactant, s), I 75 /I 75 +s and I 50 /I 50 +s treatments are studied under seven osmotic salinity potentials (0, -0.2, -0.4, -0.6, -0.8, -1, and -1.2MPa). Plants from seeds developed by surfactant in full and moderate limited irrigation (I 100 and I 75 ) show a favorable germination percentage when under saline stress treatments of -0.4 and -0.8MPa. The highest seedling lengths of 10.2 and 10.3cm were achieved for the seeds produced from I 75 and I 100 +s treatments, respectively. Utilizing the surfactant across all field treatments had a positive effect on the weighted germination index compared to the counterpart treatment. In addition, Seedlings from seeds treated by surfactant in the germination tests have higher shoot/root ratios, which show the efficiency of surfactant application in promoting a better root and shoot development under saline/drought stresses. Core ideasa) Surfactant application enhanced parental seeds tolerance against salinity conditions. b) Seeds developed by severely limited irrigation (I 50 ) had a higher G% (75%). c) Highest seedling lengths (10.2cm) obtained from plants treated by I 75 + surfactant treatment. d) Shoot/root ratio enhanced by surfactant application under salinity stress.

“…Due to the high demand for castor oil in the chemical industry, there has been consolidation of cropping systems in Brazil to meet the needs of the market; furthermore, the use of the castor bean in the Brazilian program of biodiesel production has seen a significant increase in areas where this euphorbia is cultivated in other states of the Northeast. However, for this expansion of the cultivated area to be economically viable, it is necessary for the farmers to implement new low-cost technologies of simple application for oil crops, with the aim of greater verticalisation of the entire production chain (Azevedo et al, 2001;Oliveira, 2014;César and Batalha, 2010).…”

The use of appropriate spacing when planting large crops is a technology that can be very easily applied, and that can result in a significant increase in yield. The aim of this work was to estimate the best spacing between rows in the Castor Bean cv. ‘BRS Energia’ (Ricinus communis L.), with a view to optimising maximum yield. The experiment was carried out on the Juá farm, in Itatuba, in the State of Paraíba, Brazil, in the 2015 agricultural year. The experimental design was of randomised blocks, with four replications and six treatments of different spacing between rows (0.5, 0.75, 1.0, 1.25, 1.50 and 1.75 m). Values for plant height, stem diameter, number of racemes and yield were determined at the end of the crop cycle. Reducing the spacing promoted an increase in plant height. At the smallest spacing, plants reached heights of more than 2.0 m. At the larger spacings, the plants achieved greater stem diameter and number of racemes. The highest yield was obtained at the two smallest spacings, where yields of more than 2000 kg ha-1were achieved.
