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.

Drip irrigation technique has proved its superiority over other methods of irrigation due to direct application of water and nutrient in the vicinity of root zone. A field study was conducted to evaluate the effect of irrigation and fertigation scheduling through drip irrigation in tomato (Solanum lycopersicum L.) during Rabi season of 2015-16 at Rajasthan College of Agriculture, MPUAT, Udaipur. There were three irrigation levels and five fertilization levels in split-plot design with three replications. Nutrient content in plant and fruit was found higher under the application of drip irrigation at 100 % PE (I1) and at 100 % RDF through fertigation (F1). Maximum nutrient uptake by tomato i.e. nitrogen (166.83 kg ha-1), phosphorus (41.59 kg ha-1) and potassium (183.08 kg ha-1) was recorded with treatment combination of drip irrigation at 75 % PE (I2) + 75 % RDF through fertigation + 2 foliar spray of 1 % urea phosphate (F3). Similarly, significantly maximum yield and growth attributes i.e. fruit yield (201.25 q ha-1), plant height (67.43 cm) and number of branches (12.33) were registered with treatment combination of drip irrigation at 75 % PE and 75 % RDF through fertigation + 2 foliar spray of 1 % urea phosphate. Drip fertigation method has proved to be very significant in improving nutrient uptake which finally resulting in enhancement of growth and yield of tomato crop.

<p>Rate of NPK fertilization on rice using NPK compound fertilizer needs to consider soil nutrient status and plant nutrient requirement. The research was aimed to determine the optimum rate of compound fertilizer and the effect of enriched S nutrient of NPKS compound (15-15-15-5S) and NPK compound fertilizer (15-15-15) on the growth and yield of rice. The experiments were conducted at two sites in Galuga, Ciampea Bogor, West Java from April to September 2013, using randomised complete block design with 3 replications. Experiment at site I consisted of 9 treatments: six levels of fertilizers NPKS i.e. 0; 150; 300; 450; 600; and 750 kg/ha, standard fertilizer, NPK compound fertilizer equivalent to standard, and standard fertilizer plus S. Rate of urea, SP-36, and KCl for standard fertilizer treatment was respectively 250, 75, and 50 kg/ha. At site II the treatments consisted of 6 levels of NPK compound fertilizer i.e. 0; 150; 300; 450; 600; and 750 kg/ha and the standard fertilizer with rate of 250 kg/ha of urea, 50 kg/ha SP-36, and 75 kg/ha KCl. Plot size was 4 m x 5 m planted with Ciherang variety. Data collection included chemical properties of soil before and after the experiment, plant height, number of tillers, straw weight, and dry grain weight and the nutrient uptake. The effectiveness of fertilizer was calculated by RAE (Relative Agronomic Effectiveness). Results showed that fertilizer NPKS (15-15-15-5S) at 600 kg/ha effectively increased dry grain weight from 3.63 t/ha to 4.67 t/ha, but was not significantly different from a standard fertilizer treatment. It increased dry grain weight by 29% compared to control. NPK fertilizer (15-15-15) effectively promoted growth and dry grain weight equivalent to standard fertilizer at rate of 300-750 kgha. The optimum rate of NPK compound fertilizer (15-15-15) was 440 kg/ha as was shown with the production performance of 4.12 t/ha with RAE by 58%. NPKS compound fertilizer with rate of 750 kg/ha showed the highest uptake of N, P, and K nutrients and significantly increased the available P in the soil. Whereas NPK compound fertilizer with a rate of 600 kg/ha indicated the highest P nutrient uptake. Fertilizer enrichment with sulfur on NPKS fertilizer (15-15-15-5S) did not significant affect on grain dry weight.</p>

The high yield of ginger is function of adequate and timely supply of plant nutrients. Among the various agronomic technologies influencing the production of ginger, nutrition is found to exert a great influence on growth and yield of ginger. Imbalance, low or no fertilizer application is one of the most important factors in obtaining the poor yield. Hence, the trial was taken to study the effect of organic manures (FYM, neem cake, vermicompost, Azospirillum) and biostimulants (panchakavya, humic acid and PPFM) on growth, yield and nutrient uptake of ginger at Department of Spices and Plantation Crops, Horticultural College and Research Institute, Tamil Nadu Agricultural University, Coimbatore. The growth parameters like plant height, number of leaves, number of tillers and leaf area were found to be higher in the plants fed with 50% N (FYM) +25% N (Neem cake) + 25% N (Vermicompost) + Azospirillum (5kg/ha) + Panchakavya (3%). The maximum green rhizome yield (23.55 t ha-1) was obtained with the application of 50% N (FYM) +25% N (Neem cake) + 25% N (Vermicompost) + Azospirillum (5kg/ ha) + Panchakavya (3%) per hectare. The highest uptake of nitrogen (119.06 kg ha-1) and potassium (197.56 kg ha-1) was found in the application of 50% N (FYM) +25% N (Neem cake) + 25% N (vermicompost) + Azospirillum (5kg/ ha) + panchakavya (3%) per hectare The maximum amount of Phosphorus uptake (14.35 kg ha-1) was recorded in the application of 50% N (FYM) +25% N (neem cake) + 25% N (vermicompost) + Azospirillum (5kg/ha) + humic acid (0.1%). In ginger cultivation, the application of organic manures and inorganic fertilizers commonly practiced to increase the yield and quality of rhizome. Considering the world demand for organic food, the improvement of soil health, productivity and the availability of local resources, cultivation under organic farming can be encouraged.

Salinity causes cellular damage, limiting crop productivity. Accumulation of proline is one of the main adaptive mechanisms to salinity in plants. The main objective of this study was to mitigate the adverse effects of soil salinity in boro rice by exogenous application of proline. The field experiment was conducted at the farmer’s field of Botiaghata, Khulna with Boro rice. The soil was silty clay loam having pH 7.2, EC 6.6 dS/m, CEC 26 meq/100 g soil and organic matter content 0.84%. Two rice varieties (salt-sensitive; BRRI dhan29 and salt-tolerant; BINA dhan-8) were used as test crops. There were ten treatment combinations with different concentrations of proline applied at seedling and/or vegetative stages. Recommended doses of N, P, K, S and Zn fertilizers were applied to the all experimental plots. The experiments were laid out in a randomized complete block design with three replications. Soil salinity caused a significant reduction in growth and yield of both salt-sensitive and salt-tolerant rice. Salt-tolerant rice produced higher grain and straw yields than salt-sensitive rice. Application of proline significantly increased growth, and grain and straw yields of boro rice under saline condition. There were no considerable variations in growth and yield of rice due to the different doses of proline. Increased nutrient uptake and K+/Na+ ratio in boro rice were observed due to proline application. The present study suggests that exogenous proline improves salt tolerance in rice by increasing K+/Na+ ratio and nutrient uptake. Progressive Agriculture 29 (4): 295-303, 2018

The effect of 2 rates of piggery waste on the growth, nutrient uptake and yield of barley (cv. Galleon) were compared with a fertiliser mixture of superphosphate and urea in the field. The piggery waste was either applied as a slurry (16 kL/ha or 32 kL/ha) or as a solid (0.5 t/ha or 1.5 t/ha). Both the fertiliser mix and the slurry significantly increased the growth and yield of barley while the dried manure failed to improve growth and yield. The effects of treatments on the nutrient concentration in plant tissue throughout the year were small and mainly not significant, while the increases in nitrogen and phosphorus content in the crop reflected the changes in dry matter production. The grain yield responses to fertiliser and to the slurry appeared due to an increase in nitrogen available to the crop rather than to the increase in the supply of phosphorus or other nutrients. The higher rate of the slurry reduced the boron concentration and increased the sodium concentration in the tissue but the concentrations of these elements were not great enough to affect plant growth adversely. However, the increase in sodium concentration following application of the slurry suggests that there may be some risk in the build up of sodium in the soil with the continued use of high rates of slurry, particularly in drier environments. The experiment indicates that the slurry was as effective as fertiliser in eliciting a response and was more effective, in the short term, than the dried form of manure.
