The aim of this research was to investigate the impact of different saline water irrigation levels plus potassium sulphate (K2SO4) application on growth and yield potential of pepper plants. The treatments consisted of three saline water irrigation levels (2.5, 4 and 6 dS m-1) and tab water as control. Each treatment was supplemented with different levels of K2SO4 at (zero, 2 and 4 gm K2SO4 per plant), except for the control. Plant observations were collected to evaluate plant length, fruit number per plant, fruit yield per plant, stem water potential, plant transpiration, photosynthetic rate and dry matter of shoots and roots. Results of this study indicated that K2SO4 application played a positive impact on alleviating salinity stress and improving plant growth parameters mainly under saline water irrigation levels of 2.5 and 4 dS m-1 plus 2 gm K2SO4 compared to saline water irrigation treatments which were not supplemented with K2SO4.

`Jupiter' and `Verdel' bell pepper (Capsicum annuum L.) transplants set to the depth of cotyledon leaves or to the first true leaf yielded more fruit than transplants set to the top of the rootball. Increased yields and early stand establishment criteria (number of leaves, leaf area, plant weight, and plant height) suggest that planting pepper transplants deeper than is now common is commercially beneficial in Florida. Deeper plantings may place pepper roots in a cooler environment and reduce fluctuations in soil temperature. Moderated soil temperature, in conjunction with earlier fertilizer and water acquisition, may give deeper-planted pepper plants a competitive edge in growth.

Saline Water Irrigation

Use of saline water for irrigation is essential to mitigate increasing agricultural water demands in arid and semi-arid regions. The objective of this study is to address the potential of using straw biochar as a soil amendment to promote wheat production under saline water irrigation. A field experiment was conducted in a clay loam soil from eastern China during 2016/2017 and 2017/2018 winter wheat season. There were five treatments: freshwater irrigation (0.3 dS m−1), saline water irrigation (10 dS m−1), saline water irrigation (10 dS m−1) combined with biochar of 10, 20, 30 t ha−1. Saline water irrigation alone caused soil salinization and decreased wheat growth and yield. The incorporation of biochar decreased soil bulk density by 5.5%–11.6% and increased permeability by 35.4%–49.5%, and improved soil nutrient status. Biochar also reduced soil sodium adsorption ratio by 25.7%–32.6% under saline water irrigation. Furthermore, biochar alleviated salt stress by maintaining higher leaf relative water content and lower Na+/K+ ratio, and further enhanced photosynthesis and relieved leaf senescence during reproductive stages, leading to better grain formation. Compared to saline water irrigation alone, biochar application of 10 and 20 t ha−1 significantly increased wheat grain yield by 8.6 and 8.4%, respectively. High dose of biochar might increase soil salinity and limit N availability. In the study, biochar amendment at 10 t ha−1 would be a proper practice at least over two years to facilitate saline water irrigation for wheat production. Long-term studies are recommended to advance the understanding of the sustainable use of straw biochar.

The Impact

Nitrogen (N) and Phosphorus (P) deficiency is a major yield limiting factor across the globe and their proper management plays a vital role in optimizing crop yield. This field experiment was conducted to assess the impact of soil and plant nitrogen N and P ratio on the growth and yield of wheat (Triticum aestivum L.) in alkaline calcareous soil. The study consisted of various levels of nitrogen (0, 40, 80, and 160 kg ha−1 as urea) and phosphorus (0, 30, 60, and 90 kg P2O5 ha−1 as diammonium phosphate), and was carried out in randomized complete block design (RCBD) with factorial arrangement having three replications. The result showed that the addition of 160 kg N ha−1 significantly improved biological yield (10,052 kg ha−1), grain weight (3120 kg ha−1), chlorophyll content at tillering stage soil plant analysis development (SPAD) value (35.38), N uptake in straw (33.42 kg ha−1), and K uptake in straw (192 kg ha−1) compared to other N levels. In case of P, 90 kg P2O5 ha−1 had resulted maximum biological yield (9852 kg ha−1), grain yield (3663 kg ha−1), chlorophyll content at tillering stage (SPAD value 34.36), P (6.68 mg kg−1) and K (171 kg ha−1) uptake in straw. The sole use of N and P have positively influenced the biological and grain yield but their interaction didn’t response to biological yield. The present study reveals that SPAD value (chlorophyll meter) is the better choice for determining plant N and P concentrations to estimate the yield potential.

Jojoba (Simmondsia chinensis [Link] Schneider) was tested at several sites and on various soil types to assess its production potential under rainfed conditions in semi-arid areas of New South Wales. Stands were established using either plants grown from seed or cuttings taken from selected plants. With good nutrition and weed control, plant height increased at a similar rate over the experiment at all but the most sandy site, where growth was consistently poorer despite similar climatic conditions and management. Stands established from seed had extremely variable yields. Some plants failed to produce seed after 8 years while other plants consistently produced fruit after year 4, with yields as high as 1 kg clean seed per bush by year 8. The average yield was well under 200 g plant-1 except at Trangie in 1986-87 (590 g plant-1). At year 3, 50-100% of female plants were unproductive and by year 8, between 8 and 26% of plants remained unproductive. The variation in yield of the sampled population was consistently high irrespective of seasonal conditions, and usually the upper quartile yield was only marginally higher than the mean. However, the maximum yielding plant produced up to 10 times the mean yield. By contrast, the variation in yield of individuals within a clone was low regardless of the yield potential of that clone and the maximum yielding plant rarely exceeded twice the mean yield. Some clones (A, B and F) show promise as agricultural lines as they are relatively consistent yielders and show early yield development. The highest yield obtained extrapolates to 1.1 t ha-1 at year 7 at a site which averages 417 mm rainfall per year. Further research is needed to identify the reasons for the high variability and fluctuations in yield.

The Impact

Applying biochar to the soil can mitigate problems that hinder agricultural production, such as water scarcity and low fertility soils. The objective of this research was to evaluate the impact of dry coconut husk biochar and sewage sludge combinations on soil chemical characteristics, growth, yield and water productivity of okra crop. The experiment was arranged in randomized blocks, with 6 treatments (CHB+BSS -coconut husk biochar + biochar of sewage sludge, CHB+RSS-coconut husk biochar + raw sewage sludge, BSS+RSS -biochar of sewage sludge + raw sewage sludge, CHB -coconut husk biochar, BSS -biochar of sewage sludge, WB -without biochar (control)). Plant height, number of fruits per plant, yield and water use productivity were evaluated. To evaluate the effect of biochar on soil, soil samples weretaken to determine pH, CEC, P, K, Ca, Mg concentrations after incorporation of biochar into the soil. The BSS + RSS and BSS treatments provided better results on okra production and growth characteristics with a 421.15% and 419% productivity increase, respectively, compared to the control treatment. The BSS and BSS + RSS treatments provided better water productivity,with values of 14.5 and 13.3kilogramproduced for each cubic meter of water applied, respectively.All soil chemical characteristics analyzed were modified when the biochar was incorporated into the soil. The results provide valuable insight that okra growers can embrace the use of the combination BSS+RSS and BSS, providing better yields and lower water use in growing this plant.

Irrigation Levels

Cucumber (Cucumis sativus L) is mostly cultivated by family-based farmers worldwide and processed to pickles by small to mid-sized industries generating employment and income. But irrigation management needs better investigation for adapting adequate sustainable practices. The rational use of irrigation water still has been neglected nowadays, but can improve cucumber production. The objective was to evaluate different irrigation levels on growth and yield parameters of the Amour F1 cucumber hybrid through time under greenhouse. Treatments consisted of five irrigation levels (amounts of water applied of 62, 93, 124, 155 and 186 mm), ranging from water stress to excess water. The experimental design was randomized blocks, with four replications. Vegetative growth and yield showed different responses to the irrigation levels. Plant height and internode length were less influenced by the irrigation levels, throughout the time, than stem diameter and root length. Cucumber yield was low with 62 mm and 93 mm, higher with 124 mm irrigation, and delayed in time at 155 mm and 186 mm. Water excess (186 mm) was not beneficial for pickling cucumber plants, and the amount of 124 mm was satisfactory for their development and yield. The results of this study may allow adoption of sustainable irrigation practices with no waste of agricultural water, a scarce resource worldwide

Thermal units or degree day systems can both be used to quantify relationships between plants and air temperature. The Northern Fluminense region holds no tradition for irrigated papaya (Carica papaya L.) cropping and, because of the need for irrigation, it is important knowing its growth and development characteristics under these conditions. This study aimed to determine the relationship between growth rate of papaya plants and degree days, and its effect on crop productivity, under different irrigation levels. An experiment was set up with the cultivar "Improved Sunrise Soil 72/12", in a randomized blocks design, with seven irrigation water depths and three repetitions; crop growth and yield parameters were evaluated. There were significant correlations between water depths and degree days. Polynomial models of 2nd and 3rd order appropriately fitted the relationships degree day versus plant height, stem diameter, crown diameter and number of emitted leaves, for each water depth. Growth parameters related to degree days and to the applied treatments are indicative of yield potential. The total water depth that promoted the greatest fruit yield was 2,937 mm.

The Impact

Soil salinity is a serious problem that negatively affects the productivity of plant. Reducing the impact of salinity to sustain production is the goal of scientists. The objective of this study was to determine the effect of potato peel amendments at different rates in reducing the negative impact of saline water. Common bean (Phaseolus vulgaris L. cv. Valentine) was grown in soil mixed with potato peel at different rates (0, 2.5, 5 and 7.5%). To achieve this objective, plants were irrigated with three levels of saline water (0, 50 and 100 mM) to induce stress at the vegetative stage. The result showed that significant reduction in physiological parameters, plant growth and yield of common bean after irrigation with saline water. Soil amendment with different rates of potato peel significantly increased number of pods per plant, weight of pods per plant, pod length, chlorophyll content and relative water content of common bean irrigated with saline water (50mM) as compared to non-amended soil. Potato peel application also reduced electrolyte leakage and improves soil properties by reducing the salinity of soil. Furthermore, among all potato peel rates used in this investigation, the 7.5% rate had a better result for common bean production. Conversely, potato peel did not improve the yield of beans grown under high concentration of saline water (100 mM). In conclusion, soil amendments with potato peel at 7.5% rate could be successfully used as a cost effective management practice to enhance bean production in soils stressed with high salt content
