This study assessed the effects of irrigation with desalinated water on the growth of lettuce (Lactuca sativa L.). Two experiments, the first using saline and the second desalinated irrigation water, respectively, were designed to grow lettuce in plots (22 m × 0.4 m × 0.4 m) under controlled greenhouse conditions. Three levels of saline irrigation water and tap water (control) were used for the first experiment. In the second experiment, the three saline levels underwent a desalination process. Each experiment was carried out twice, in succession, with two replications. The results from the first experiment showed that the use of saline irrigation water caused an increase in the salinity level of soil and, consequently, adversely affected lettuce growth and yields. The results from the second experiment showed that the use of desalinated irrigation water does not negatively affect soil salinity and lettuce growth and yield. However, the need for additional application of the elements such as Ca2+ and Mg2+ was also identified since continued use of desalinated water irrigation correlated with a decrease in the sodium adsorption ratio (SAR), leading to increased risk of soil sodicity. This is due to the elimination of nutrients during the desalination process.

This study documents changes in yield, growth, soil salinity (ECe) and leaf sodium (Na) and chlorine (Cl) concentrations in mature Valencia orange [Citrus sinensis (L.Osbeck)] trees on sweet orange (Citrus sinensis) rootstock in response to increased levels of Na and Cl in irrigation water. Four levels of salt, ranging from the river-water control (0.44 dS/m) to 2.50 dS/m, were applied over a 9-year period through an under-tree microsprinkler system to trees in the Sunraysia area of the Murray Valley in south-eastern Australia. A salt-balance model showed that evapotranspiration was reduced by salinity, whereas leaching fractions increased from an average 24% in the control to 51% in the most saline treatment. The high leaching fractions were achieved as a result of freely draining soils and good irrigation management, and allowed us to maintain low to moderate levels of soil salinity throughout the trial and minimised the effect of salt treatment on fruit yield. Soil salinity increased almost linearly in response to irrigation-water salinity during the first year, and fluctuated seasonally thereafter; however, very few readings exceeded 3 dS/m, even in the highest treatments. By contrast, leaf Na and Cl concentrations in the highest salt treatment continued to increase over the first 4 years. The relationship between yield and soil salinity was extremely weak, but yield did decrease as foliar concentrations of Na and Cl increased: in Year 9, leaf Na in the highest treatment relative to the control was associated with a predicted reduction of 17% in yield and 59% in annual trunk-diameter growth.

Three cultivars of Poinsettia (Annette Hegg Lady, V-14 Pink, and Topwhite) were each treated with the same three concentrations of Na and Ca, plus a Tap water and Distilled Water Control. Plants were evaluated for the following parameters: quality (bract diameter, height, foliar blemishes), dry weights (root and shoot), and Na and Ca contents (root and shoot). Postharvest keeping quality was evaluated in a subsequent study with the same cultivars and treatments. It was found that high levels of Na reduced bract size, height, and overall quality. Root tissue did accumulate Na, but only to a certain level (approx. 300 g/kg). Shoot tissue continued to accumulate Na as concentration of Na increased in the irrigation water. Na accumulation in shoot tissue was approx. doubled in Topwhite when compared to V-14 Pink and Annette Hegg Lady. Postharvest keeping quality was not reduced by increased Na concentrations in irrigation water.

Main Factor

Irrigation with saline water adversely affects rice production and degrades land productivity in the coastal zones of many countries in the world. This study aimed at developing a suitable irrigation management practice to reduce the harmful effects of salinity on rice production under saline water irrigation. An experiment in raise-bed lysimeters was set in a split-split-plot design with irrigation–drainage practice as the main factor, irrigation water salinity as the sub-factor and rice variety as sub-sub factor; main factor and sub-factor comprised four treatments and the sub-sub factor comprised three treatments, each with three replications. The treatments of the main factor were – T1: 2-5 cm continuous ponding, T2: continuous saturation, T3: changing irrigation water after 3 days of application by maintaining 2-5 cm ponding depth, and T4: changing irrigation water after 5 days of application by maintaining 2-5 cm ponding depth. The sub-factor comprised – SL1: fresh water as control, SL2: saline water of 6 dS m-1, SL3: saline water of 9 dS m-1, and SL4: saline water of 12 dS m-1. The sub-sub factor comprised three salt-tolerant rice varieties V1: Binadhan-8, V2: Binadhan-10, and V3: BRRI dhan-47. The irrigation–drainage practices T2 and T3 provided significantly (p£0.05) improved growth and yield attributes of the rice varieties under salinity water level SL3 and SL4 compared to T1 and T4 treatments. The treatment T3 maintained least exposure of the crop to high degree of salinity and produced satisfactory plant attributes by inhibiting the detrimental effects of salinity. Therefore, T3 is suggested for adoption in practical fields when provision for removing high saline water from the rice fields can be arranged.

Four Levels

Lettuce (Lactuca sativa L.) is a horticultural plant that is beneficial for health. Efforts are being made to expand the plant area. One of them is by utilizing marginal land such as peatlands.  Peatlands in Indonesia are the most extensive soils in various tropical countries in the world that have low soil fertility and high acidity so that they are not optimal for lettuce growth. The provision of organic material can increase soil fertility by improving physical, chemical, and biological soil properties so that it can support lettuce growth. This study aims to determine the dose of cow manure and the dosage of oil palm empty fruit bunch fertilizer and the optimal dose interaction for growth and yield of lettuce. This research was conducted from June 2019 to August 2019 in Bengkulu City. This study uses a Completely Randomized Design consisting of two factors, which are repeated three times. The first factor is the dose of cow manure with three levels, namely: 0 tons ha-1, 15 tons ha-1, and 30 tons ha-1. The second factor is the dose of oil palm empty fruit bunch fertilizer, which consists of four levels, namely 0 tons ha-1, 5 tons ha-1, 10 tons ha-1, and 15 tons ha-1. The results showed that the dosage of cow manure 15 tons ha-1 and without the application of empty fruit bunches fertilizer gave the best results in leaf length of 18.674 cm. The best dose of cow manure for growth and yield of lettuce is 15 ha-1. The application of OPEFB fertilizer has not been shown to affect the growth and yield of lettuce.

[GROWTH AND LETTUCE YIELD (Lactuca sativa L.) BY GIVING MANURE AND RICE HUSK ASH IN INCEPTISOL].  Increasing market demand for lettuce (Lactuca sativa L.) makes the prospect of developing lettuce very promising. Bengkulu Province is dominated by inceptisol soil types which have low soil fertility, making it less optimal for lettuce growth. Giving organic matter can increase soil fertility through improving soil physical, chemical and biological properties so that it can support the growth of lettuce. This study aims to determine the dosage of manure, the dose of rice husk ash and the optimal dose interaction for lettuce growth and yield. This research was conducted from May 2018 to July 2018 in Medan Baru, Muara Bangkahulu Subdistrict, Bengkulu City. The research design used was a Completely Randomized Design (CRD) consisting of two factors and repeated 3 times. The first factor is the dosage of cow manure with three levels, namely: 0 tons/ha, 15 tons/ha, and 30 tons/ha. The second factor is the dose of rice husk ash which consists of three levels, namely 0 tons/ha, 3 tons/ha, and 6 tons/ha. Data from the observations were analyzed statistically by Analysis of Variance (ANOVA) using the F test at the level of 5%. To determine the dosage of manure, the dose of rice husk ash and the optimal combination of doses for growth and yield of lettuce used the Polynomial Orthogonal method. The results showed that there was no interaction between cow manure and rice husk ash on the growth and yield of lettuce. The effect of cow manure has not shown the optimum dose for growth and yield of lettuce. The addition of manure doses up to 30 tons/ha was able to increase the value of plant height, number of leaves, leaf area, and fresh weighted plant weight of 0.189, 0.038, 0.931 and 0.104 respectively. Giving rice husk ash up to a dose of 6 tons/ha did not have a significant effect on all observed variables.

ABSTRACT: The present research work was undertaken to find out the phytotoxic effects of different concentrations of aqueous extracts of leaves, stems and root of milkweed (Calotropis procera) in the Agronomic Research Area of Department of Agronomy, Faculty of Agriculture, Gomal University, Dera Ismail Khan, Khyber Pakhtunkhwa (KPK), Pakistan during 2013-14 and 2014-15. The treatments consisted of different concentrations of aqueous leaf, stem and root extracts (10, 20, 30 and 40%) of milkweed, which were compared with tap water (control). The results showed that the reduction of all studied parameters, including weeds, growth and yield of wheat was proportional to the concentration of aqueous extracts of milkweed in use. The level of inhibition was concentration-dependent as inhibition increased with an increase in the concentration of aqueous extracts of all three plant parts of milkweed. Therefore, application of maximum concentration (40%) of aqueous leaf, stem and root extracts correspondingly reduced all the studied parameters. On the basis of the findings, it is concluded that the Calotropis procera should be removed near the cultivating wheat fields because it contains some phytotoxic substances, which may be leached out by the roots and cause serious losses to the growers and crop species.
