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.

Boron is an important micronutrient, required for all plant growth, and critical for high yield and quality of crops. The aim of the present research was to determine the effects of boron on pot-grown parsley (Petroselinum sativum Hoffm.). The experimental design consisted of four treatments using Hoagland-Arnon (1950) nutrient solutions with two different boron concentrations (B1 - 15 ppm and B2 - 150 ppm), each with and without 10 ml humic acid addition (HB1 and HB2), and controls with full strength Hoagland-Arnon solutions. Growth analyses of the parsley revealed that 15 ppm boron application caused an increase in root length leaf fresh and dry weight root fresh and dry weight and leaf area compared to control values. 150 ppm B (B2) concentration decreased all growth parameters compared to controls. The two humic acid treatments (HB1 and HB2) did not increase any of those growth parameters either in controls (C) or in the two boron (B1 and B2) concentrations. Analysis by (ICP-MS) revealed that B content in the leaves increased gradually in B1 and B2, as well as in both humic treatments where in HB2 it increased to 99.38% compared to B1. In the leaves, Mn, Zn and Fe contents behaved the same as B, increasing in all treatments, with the amounts in HB2 being significantly greater than in C, B1 and B2 leaves.

The ability of benzothiadiazole (BTH), humic acid (HA) and their combination when used as seed soaking to induce systemic resistance against a pathogenic strain of Fusarium oxysporum was examined in four soybean cultivars under greenhouse conditions. Both inducers and their combination were able to protect soybean plants against damping-off and wilt diseases compared with check treatment. These results were confirmed under field conditions in two different locations i. e Minia and New Valley governorates. The tested treatments significantly reduced damping-off and wilt diseases and increased growth parameters, except number of branches plant-1, and seed yield. Application of BTH (0.25) + HA (4 g/l) was the most potent in this respect treatment. Soybean seed soaking in BTH+ HA recorded the highest activities of the testes of oxidative enzymes followed by BTH in the four soybean cultivars. Whereas, HA treatment was recorded the lowest increased of these oxidative enzymes. Also, similar results were obtained in case of total phenol but HA increased the total phenol more than BTH in all tested cultivars.

Increased use of recycled water along with inherent soil salinity problems on golf courses make salinity an important issue for golf course management. The objective of this study was to investigate if using humus on golf fairways by topdressing or spraying can alleviate soil salinity problems and improve turf quality. The study was conducted from 2015 to 2017 at Aurora, CO, and Medora, ND. Treatments included an untreated control, topdressing (sand, sand + peat), and spraying of humic acid. Our results showed that the application of humus increased the soil microbial biomass and improved turf quality on fairways either with a soil salinity problem or irrigated with recycled water. The effects on turfgrass health and turf quality were dependent on the rates of humus applied. Humic acid at 3 gal/acre was equivalent to topdressing sand + peat (80/20 v/v) and consistently showed improved turf quality over the untreated control. Soil properties also were affected by the application of humus. Soil pH, electrical conductivity (EC), bulk density, water infiltration, and microbial biomass may have had an indirect contribution to turf quality.

Rooted cuttings of crepe myrtle (Lagerstroemia indica L. × L. fauriei `Muskogee') were transplanted into 3.8-L black polyethylene containers filled with a bark-based rooting substrate and exposed for 2 months during Summer 1995 to either of three container shielding treatments: containers shielded from insolation (container shielded inside a whitewashed 11.4-L black polyethylene container), containers exposed to insolation, or containers shielded for 1 month then exposed for 1 month. Mean highest temperature in the western quadrant of rooting substrate of exposed containers was 16°C higher than for those in shielded containers. Containers exposed for 2 months had reduced root and shoot growth and increased leaf N compared with the other two treatments. Crape myrtle plants were next transplanted into 27.0-L polybags, transferred into a temperature-controlled glasshouse, and fertigated to container capacity every 3 days with humic acid extract at concentrations of 0, 50, 150, or 300 μl·L–1 for 2 additional months. Effects of the container shielding treatments for all growth parameters remained evident until the end of the experiment. Shoot and root extension growth of plants previously in containers shielded for 2 months and containers exposed for 2 months, responded in a quadratic fashion to humic acid extract concentration levels.

Due to the different agricultural practices such as second cropping or more for the increase product obtained from the areas of suitable climate, some differences in harvesting stages of plants have been occurred. The study was carried out in the Menemem location of Izmir in the coastal Aegean region of Turkey under Mediterranean climate in 2018 and 2019 to determine the performance of corn cultivars in different maturity stages. Seven varieties of corn (Everest, Aga, Kilowatt, Burak, Samada-07, P30B74 and P31Y43) were harvested at 3 different growth stages (silking, end of milk and dough stages) to determine the changes in some parameters of growing, forage quantity and quality. The highest average of dry forage yield (24159 kg ha-1 average of years) was determined at the third harvest date. The maximum cob rate was also measured at the third harvest date, but the maximum leaf and stalk rates were measured at the first harvest date. The average protein rate decreased throughout the growing period while ADF and NDF increased. Almost all of the varieties were found to have large leaf areas. The Burak variety came to the fore due to its long length and relatively thick stalk features and high green and dry yields. Moreover, P31Y43 was determined to have a high quality in addition to high green and dry grass yields. Therefore, the Burak and P31Y43 can be suggested in terms of high parameters both quantity and quality under different crop conditions for increase production.

In this research, the effects of different concentrations of jasmonic acid ( JA) on growth parameters of flower diameter, number of flowers, dry flower weight, plant height, 1000-seed weight and also, photosynthetic pigments in marigold (Calendula officinalis L.) were investigated. To achieve this aim, marigold planted in pots and jasmonic acid were sprayed on the shoots at concentrations of 0.75, 150 and 225 μM. Data were compared by Duncan test. The results showed that different concentrations of jasmonic acid significantly affected the dry flower weight, plant height and 1000-seed weight. The maximum plant height and 1000-seed weight were reached by 150 μM jasmonic acid, while 225 μM was recorded the dry flower weight.
