Soil salinity and sodicity are among the main problems for optimum crop production in areas where rainfall is not enough for leaching of salts out of the rooting zone. Application of organic and Ca-based amendments have the potential to increase crop yield and productivity under saline–alkaline soil environments. Based on this hypothesis, the present study was conducted to evaluate the potential of compost, Ca-based fertilizer industry waste (Ca-FW), and Ca-fortified compost (Ca-FC) to increase growth and yield of maize under saline–sodic soil conditions. Saline–sodic soil conditions with electrical conductivity (EC) levels (1.6, 5, and 10 dS m−1) and sodium adsorption ratio (SAR) = 15, were developed by spiking soil with a solution containing NaCl, Na2SO4, MgSO4, and CaCl2. Results showed that soil salinity and sodicity significantly reduced plant growth, yield, physiological, and nutrient uptake parameters. However, the application of Ca-FC caused a remarkable increase in the studied parameters of maize at EC levels of 1.6, 5, and 10 dS m−1 as compared to the control. In addition, Ca-FC caused the maximum decrease in Na+/K+ ratio in shoot up to 85.1%, 71.79%, and 70.37% at EC levels of 1.6, 5, and 10 dS m−1, respectively as compared to the control treatment. Moreover, nutrient uptake (NPK) was also significantly increased with the application of Ca-FC under normal as well as saline–sodic soil conditions. It is thus inferred that the application of Ca-FC could be an effective amendment to enhance growth, yield, physiology, and nutrient uptake in maize under saline–sodic soil conditions constituting the novelty of this work.

Abstract A facility of BaPS (Barometric Process Separation) and indoor incubation experiments were used to determine the effect of soil salinity on soil respiration and nitrogen transformation. The rates of soil respiration, gross nitrification, denitrification, ammonium and nitrate nitrogen concentrations and relevant soil parameters were measured. Results showed that soil respiration and nitrification and denitrification rates were all affected by soil salinity. Furthermore, the effect of soil salinity level on nitrification and denitrification rates had a threshold value (EC1:5 = 1.13 dS/m). When soil salinity level was smaller to this threshold value, the rates of nitrification and denitrification increased with soil salinity while they were reduced when soil salinity level was larger than the threshold value. Moreover, the changing law of soil respiration rate with soil salinity was similar with the nitrification and denitrification rates while the variation tendency was opposite. In addition, the transformation form urea to ammonium and nitrate nitrogen was also reduced with the increase of soil salinity and the reduced effect could be expressed by exponential functions.

SUMMARYThe groundwater in some parts of north India is generally saline and not suitable for drinking. However, it can be used for growing salt-tolerant crop plants. To explore the potential of using saline groundwater for farm production, a field experiment was conducted at Shahpur village, near Hisar in Haryana State, India, to study the effect of different qualities of irrigation water on mustard (Brassica juncea, cv. RH–30) crop growth, yield, water use efficiency and soil salinity. Treatments consisted of combinations of irrigation with saline groundwater (electrical conductivity (EC) 7.48 dS m−1), and a good quality canal water (EC 0.4 dS m−1) applied either alone, as blends or in alternate applications. In all treatments, canal water was used for pre-sowing irrigation. In mustard cultivation, saline groundwater with an EC of 7.48 dS m−1 can be used safely to supplement all post-sowing irrigations with marginal decline in crop yield. Irrigation with saline groundwater gave a yield as high as 95% of the optimum crop yield obtained with fresh canal water. The temporal variation in salinity showed that mustard yield responds to the average salinity of the soil during the growing season. Thus saline groundwater is a good water source to exploit for supplemental irrigation.

Macadamia growers have responded to increasing soil acidity in plantations by applying ameliorants, but optimum pH for production has not been identified. The effects of lime applications on the growth, yield and leaf composition of macadamia (Macadamia integrifolia Maiden and Betch) trees were investigated at each of two sites (Pomona and Cootharaba) with acidic sandy soils in south-east Queensland. Trees at the Pomona site had been established for 6 years whereas, at Cootharaba, the trees had been recently planted. The effects of annual applications of nitrogen and nitrogen plus lime were also studied at the Cootharaba site. Tree parameters and soil properties were monitored each year for 5 years after treatment application in 1988. Treatments resulted in pH (water) values ranging from 4.6 to 7.5 and 4.3 to 6.5 at the Pomona and Cootharaba sites, respectively. with a concomitant range in soil Ca and A1 levels. Despite the wide range in soil properties, lime had no significant (P < 0.05) effect on nut-in-shell yield in any year, and the results suggest that macadamia is relatively tolerant of soil acidity. However, yields from treatments with pH values greater than 5.5 tended to be lower than those with more acidic pH values, suggesting that overliming may adversely affect long-term productivity. High lime rates also resulted in a marked reduction in the number of proteoid roots. At the Cootharaba site, nitrogen treatments significantly (P < 0.05) increased nut-in-shell yield despite the juvenile growth stage of the trees precluding nut yield until the 1993 season. Although lime applications at the Cootharaba site resulted in some increase in leaf Ca concentrations, treatments at the Pomona site, with older trees, had little effect on leaf nutrient composition.

The dry matter yield of 11 tropical legumes, 10 temperate legumes and 11 tropical grasses was examined in pot experiments on a clay soil with increasing levels of sodium chloride. A mathematical model was fitted to the yield-salt level curves for each species and both the half yield soil salinity level and zero yield soil salinity level were estimated. Species were ranked in relation to their salt tolerance at half and zero yield and these values were expressed in terms of the electrical conductivity of the soil saturation extract. Grasses showed a greater ability to persist at high salt levels than the legumes. The most tolerant grasses were Chloris gayana, Panicum coloratum, Pennisetum clandestinum, Sorghum almum and Digitaria decumbens. Medicago sativa, which was included in both temperate and tropical groups, was the most tolerant legume of both groups. The tropical legumes Macroptilium lathyroides and Macroptilium atropurpureum were almost equivalent to M. sativa in their salt tolerance. The least tolerant grass was Setaria anceps and the least tolerant tropical and temperate legumes were Desmodium uncinatum and Trifolium semipilosum respectively. Both Na and Cl percentages in the plant generally increased with increasing salt but no consistent relationship was found between plant salt tolerance and Na and Cl content. The field implications of the high salt tolerance of certain grasses is discussed in relation to the establishment of permanent grass-legume pastures on saline-sodic soils.

A field experiment was carried out at the research farm of National Research Centre for Onion and Garlic, Manjari, Pune (Maharashtra), India during kharif season of 2004 and 2005 to find out the effect of application of zinc and iron and their different modes of applications on growth, yield, and quality of onion. There were 27 treatment combinations with Zn and Fe were applied either in the soil or as foliar spray with cow dung slurry/FYM/gibbrelic acid/amino acids/2,4- D to onion. Application of Zn significantly increased the bulb weight (73.9 g), bulb yield (45 t/ha) when applied with 2,4-D (3 ppm) as foliar spray. Zinc application significantly influenced the bulb quality and recorded the highest ‘A’ grade bulbs and the lowest poor quality ‘C’ grade bulbs when applied with 2,4-D (81.9%) as foliar spray. The maximum medium ‘B’ grade bulbs were obtained with the application of Fe with cow dung slurry (11.4%). Bangladesh J. Agril.
