In order to study the effect of different manure and chemical fertilizer levels on qualitative and quantitative characteristics of safflower in the condition of irrigation with municipal wastewater, an experiment was conducted as split plot basis of randomized complete design in Lakhshah region locate in Zahedan city, Iran. The treatments were comprised of two levels of irrigation, W1= Well water and W2= Treated wastewater, in main plots and sub plots consisted of F1: control (without consumption of manure and chemical fertilizer), F2: Recommended manure, F3: Half of recommended manure and chemical fertilizer (N, P and K), and F4: Recommended chemical fertilizer (N, P and K). The results showed that Treatment of treated wastewater had a positive and significant influence on all yield components, and the most influence was shown on 1000 seed weight. Also, irrigation with wastewater significantly increases the dry and fresh yield and grain yield of safflower than ordinary water. Among the fertilizer treatments, complete treatment of chemical fertilizer N, P and K had the greatest effect on increase of yield and grain yield components. In this experiment, water treatment hadn’t significant effect on accumulation of Cr, pb, Fe and Mn in safflower grain, and soil. While, fertilizer treatment had only a significant influence on the accumulation of Fe and Mn in safflower grain, but between these treatments wasn’t saw any significant difference on the accumulation of Cr and pb. In general, the results of this experiment showed that irrigation with wastewater and application of complete fertilizer with manure is recommended.

In order to evaluate the yield, yield components and some physiological and qualitative traits of corn treated with nitrogen fertilizers (biological, chemical and integrated), a field experiment was conducted at the Agricultural Research Station of Khorramabad during 2016 growing season. Treatments were arranged in a complete randomized block design with four replications. Experimental treatments consisted of 100% chemical fertilizer (urea), bio-fertilizer (nitroxin), integration of bio-fertilizer + 25% chemical fertilizer, integration of bio-fertilizer + 50% chemical fertilizer, integration of bio-fertilizer + 75% chemical fertilizer and the control. Results showed that the effect of different treatments of fertilizers on all measured traits, except for number of rows in each ear and carotenoids, was significant. The results indicated that integration of bio-fertilizer + 75% chemical fertilizer affected the highest grain yield (9.31 t ha–1), dry biological yield (20.96 t ha–1), number of kernels in each row (41.67), plant height (201.02 cm), hectoliter weight (0.82 g cm–3), chlorophyll b (0.43 mg g–1 FW), total chlorophyll (1.1 mg g–1 FW) and leaf area index (LAI) (4) and there was no significant difference among this treatment and 100% chemical fertilizer (N) and integration of bio-fertilizer + 50% chemical fertilizer treatments in all measured traits. The greatest harvest index (45.8) and grain protein-content (9.1%) resulted from the integration of biofertilizer+ 50% chemical fertilizer treatment. Also the highest 1000-grains weight (281.13 g) and chlorophyll a (0.66 mg g–1 FW) were caused by 100% chemical fertilizer (urea) treatments. Results showed that integration of bio-fertilizer + chemical fertilizer could be considered as a means to reduce the consumption of chemical fertilizers for sustainable agriculture.

The objectives of this study were to determine the nutrient losses through the soil columns with the variation of soil and fertilizer. The experiment was conducted in a net house of Sher-e-BanglaAgriculturalUniversity, Dhaka, Bangladesh during July–November to study the effect of fertilizer and manure on the growth and yield of T. aman rice and leaching loss of nutrients through undisturbed soil columns. The experiment consists of 2 factors i.e. soils and fertilizer plus manure. Two soils (S1= SAU Soil and S2= Sonargaon Soil) with 4 levels of fertilization, as F0: Control, F1: 100% N120P20K45S20 (FRG 2012), F2: 50% NPKS + 5 t/ha cowdung, F3: 50% NPKS + 2.1 t/ha poultry manure were used in the experiment. T. Aman (BR11) rice was grown in the soil cores. Altogether, there were 8 treatment combinations and the treatment combinations were replicated 3 times. Twenty four undisturbed soil cores collected in PVC pipes were placed at the bottom of the perforated plastic containers and two holes of each plastic container were connected to a conical flask that was used to collect column leachate.  Leachates were collected at 25, 35, 45, 55, 65 and 75 DAT (Days after transplanting) and analyzed for N, P, K and S. The leachate N, P, K and S concentration varied with different soil, fertilizer and time. The higher N and S concentrations were found in the leachate of SAU soil and higher leachate K concentrations were obtained in Sonargaon soil. The higher amounts of N leaching were observed during 45–55 DAT and higher leachate N concentrations were found in F1 treatment. Higher leachate K concentrations were found in 100% chemical fertilizer treatment and higher leachate K concentrations were found at 35DAT in all fertilizer treatments. The leachate P concentration increased at 35 DAT and then decreased. Results revealed that soil had no significant effect on the yield and yield parameters. The yield contributing characters and yields were significantly affected by fertilizer and manure application. The highest effective tillers/core (17.0), plant height (105.6 cm), panicle length (23.70 cm), grain yield (0.046 kg/core) and straw yield (0.053 kg/core) of T. Aman rice were found from F1 (RDCF) treatment. The highest 1000-grain wt. (23.70 g) was obtained from F2 and filled grain/panicle (121.8) from T3 treatment and the lowest in F0 treatment. The highest grain yield was found by the application of recommended dose of chemical fertilizer which was statistically similar to F3 (50% NPKS + 2.1 ton poultry manure) treatment. The combined effects of soil and fertilizer were not significant but the highest grain (0.049 kg/core) and straw yields (0.056 kg/core) were recorded from S2F1 (Sonargaon Soil + 100% NPKS) treatment combination.J.

Field experiments was conducted during the 2015 rainy season at Teaching and Research Farm of Department of Crop Science, Taraba State College of Agriculture Jalingo, to investigate the effect of Nitrogen rates on the growth and yield of Bambara groundnut (Vigna subterranean (L.) Verdc) in Jalingo. The experiments was laid out in split-plot design with three replications and three nitrogen rates, 20kgNha-1, 25kgNha-1 and 30kgNha-1 as main plot treatment while four intra-row spacing, 20cm, 25cm, 30cm and 35cm as the sub plot treatment. The sub plot size was 3m x 2m (6m2). The nitrogen rate doses were applied a week after emergence of the seedlings. Data collected were, percentage seedlings emergence, number of leaves per plant, number of branches per plant, plant height, number of nodules per plant, number of effective nodules per plant, number of non-effective nodules per plant, days to 50% flowering, number of pods per plant, number of seeds per plant, 100 seeds weight, grain yield per plot and grain yield per ha-1. Data collected were subjected to Analysis of Variance (ANOVA), means were separated using Least Significant Difference (LSD). The results showed that nitrogen rate applied had no significant influence on growth and yield characters. However, significant influence was recorded of intra-row spacing on number of leaves per plant and number of branches per plant at 6WAS with a mean value of 48.24 and 16.80 respectively. Intra-row spacing, 25cm gave the highest mean number (3.14) of non-effective nodules per plant at 30 DAS while 25cm gave the highest number of days to 50% flowering. The result of the interaction revealed that there were significant interaction between Nitrogen rates and intra-row spacing on the number of leaves at 3 WAS and 6WAS. It is recommended that nitrogen rate of 20kgNha-1 and intra-row spacing of 35cm be adopted for Bambara groundnut in Jalingo.

In order to determine the effects of sowing date on physiological characteristics, yield and yield components of six sweet maize hybrids, an experiment was arranged in split plot based complete randomized block design with three replications. Sowing date in two levels (15 June and 1 July) and sweet maize hybrids in six variants (‘Chase’, ‘Temptation’, ‘Challenger’, ‘Basin’, ‘Obsession’ and ‘Ksc403su’) were the treatments. Results of ANOVA revealed significant difference of sowing date and sweet maize hybrids on the number of days for tassel emergence, number of days to anthesis, plant height, cob height, stem diameter, plant dry weight, cob dry weight, number of grain rows, length flowers, number of leaf above the cob, raffinose content of grain and grain yield. Mean comparisons showed that the highest grain yield was obtained for ‘Basin’ variety and it was obtained from the crop established on the 15th of June as planting date. In temperate regions, maize potential productivity seems to be more limited by the amount of solar radiation available around silking (determinant of grain set) than during grain filling (determinant of grain weight).

In this study, we aimed to determine the effects of tillage systems (TS) on wheat grain yield, yield components, and physicochemical properties under rain-fed conditions over 2 years (2018–2019) in the Kuhdasht region in southwestern Iran. The tillage treatments were a combination of conventional tillage (CT), reduced tillage (RT), and no tillage (NT) systems based on randomized complete blocks with three replications. Wheat grain yields and yield components, physical properties (geometrical dimensions, sphericity, thousand-grain mass (TGM), water absorption (WA), volume (V), and density), chemical composition (protein content (PC), water content (WC), fiber content (FC), ash content (AC)), surface color parameters (L*, a*, and b*), and correlations among measured parameters were assessed. The results showed that wheat grain yield and yield components were significantly affected by TS (p < 0.01). The wheat grain yield was higher under CT (2.72 t ha−1), with a significant difference between RT (1.76 t ha−1) and NT (1.20 t ha−1). The highest TGM (49.19 g) was achieved under CT, followed by RT (43.41 g), with the lowest (39.17 g) in the NT system. TS had significant effects on certain physical properties of wheat grains (p < 0.01). Wheat grain, size, shape, and mass values were higher under CT than RT and NT systems in all experimental years. CT resulted in the highest WA, while the lowest resulted from NT. TS had no significant influence on the density of the grains. TS had significant effects on PC, AC, and WC values of grains at the 1% probability level and on FC at the 5% level. Higher PC values were obtained under the CT system (13.07%, against 11.90% and 10.67% for RT and NT, respectively) in all growing seasons. Additionally, the AC was significantly lower in the sample grains under RT (2.38%) and NT (2.43%) than in those from CT (2.56). The FC was higher under NT (15.73%) than RT (13.73) and CT (13.71%). The grain WC was significantly higher under NT (7.57%) than RT (6.79%) and CT (7.0%). The TS significantly affected the surface color parameters of grains, while the L* (lightness) and b* (yellowness) values of grains under CT were higher than in RT and NT.

There is conflicting informations regarding the advantages of planting of stock seed (SS) over Extension Seed (ES) classes. An experiment to study the effect of different seedclasses on grain yield and yield components of five rice varieties was carried out at two locations i.e. Sukamandi and Muara Field Station during the wet and dry season of 2009. The treatment consisted of five rice varieties, namely: Ciherang, Mekongga, IR64, Cigeulis and Situ Bagendit, and their respective seed classes: namely breeder seed, foundation seed, stock seed and extension seed. The experiment was arranged in a split plot design with three replications, where rice varieties were as main plots and seed classes as sub plots. Variables to be evaluated consisted of: quality of seed before sowing, plant growth, yield components and grain yield. Performance of the observed variable of each rice variety derived from four different seed-classes in each location and planting season were not significantly different. Differences of seed classes only affected the percentage of seed purity. There was no significant difference on the grain yield and the seed yield obtained from different seed classes of each variety. These results disprove the belief that the higher seed class the higher productivity, which was found to be a wrong perception. Seed certification is designed to maintain the genetic purity of variety and not to increase the productivity.

The high demand of barley for animal feed and the scarcity of fresh water increase the need for the reuse of treated wastewater as an alternative source for irrigation. Therefore, two-field experiments were conducted to study physiological processes, plant growth, grain yield and yield components of four-barley cultivars grown under four-irrigation treatments using treated wastewater or fresh water. Plants of four-barley cultivars (ACSAD176, Rum, Athroh, Yarmouk) were exposed to four-irrigation treatments: 1) Full-irrigation using treated wastewater (FWW); 2) Supplementary-irrigation using treated wastewater (SWW); 3) Supplementary-irrigation using fresh water (SFW); 4) Non-irrigation treatment (Rainfed). Full- or supplementary-irrigation using treated wastewater reduced stomatal resistance and increased plant photosynthetic rate, plant height, grain yield and yield components as estimated by grain number plant-1 and 1000-grain weight compared with rainfed conditions. Plants grown under supplementary-irrigation using treated wastewater produced higher grain yield than those grown under supplementary-irrigation using fresh water. Rum cultivar had the highest grain yield among cultivars grown under irrigation. Under rainfed conditions, Rum and ACSAD176 had the highest grain yield. In conclusion, supplementary-irrigation using treated wastewater improved grain yield of barley and can be a better choice to conserve water and reduce the risk of plant lodging at the end of the growing season. Irrigation barley using treated wastewater did not change heavy metal (Zn, Cd, and Pb) concentrations in soil or harvested grains.

AbstractA 2-year fertilization experiment was conducted to study the effect of different ratios of organic (pig) manure on wheat yield and nitrogen use efficiency (NUE). The four treatments were no nitrogen (N) (CK); 100% chemical fertilizer N (urea; T1); 70% chemical fertilizer N + 30% organic manure N (T2) and 50% chemical fertilizer N + 50% organic manure N (T3), with the same amount of applied nitrogen (120 kg/ha). The results showed the maximum grain yield (3049 kg/ha), crop nitrogen uptake (216 kg/ha), NUE (65.4%) and accumulated nitrate nitrogen (NO3−-N in 0–200 cm, 142 kg/ha) were observed in the T1 among all treatments in the first year. However, the largest grain yield (5074 kg/ha), crop nitrogen uptake (244 kg/ha) and NUE (82.5%) were under T2 treatment in the second year. Furthermore, T2 had the maximum NO3−-N content in 0–100 cm layer (116 kg/ha), especially 0–40 cm layer, and the lowest NO3−-N content in 100–200 cm (58.8 kg/ha). However, 50% organic manure N in T3 increased apparent nitrogen loss by 39.0% compared to that in T2. Therefore, 30% organic manure N application was more conducive for enhancing wheat yield and NUE and promoting environmental safety after 1-year fertilization time.

Balangu (Lallemantia sp.) is a medicinal herb with a variety of applications, all parts of which have economic uses, including leaf for extraction of essential oils, as a vegetable and potherb, seed for extraction of mucilage and edible or industrial oil. To investigate the effect of cultivation season and standard chemical and nano fertilizers (n) on the yield components and antioxidant properties of Dragon’s head, a factorial experiment based on randomized complete block design was conducted with 12 treatments and three replications. Experimental treatments consisted of two seasons (spring and winter cultivation) and six levels of fertilizer (control, NPK-s, NPK-n, Fe-chelated-n, NPK-n + Fe-chelated-n, NPK-s + NPK-n + Fe-chelated-n). The traits included grain yield per plant, essential oil percentage and yield, mucilage percentage and yield, antioxidant properties in the seeds and leaves, including total phenols and flavonoids content, DPPH radical scavenging, and nitric oxide and superoxide radical scavenging. The results showed that winter cultivation had a noticeable advantage over spring cultivation across all of the traits. The highest grain yield per plant was obtained in winter cultivation using NPK-n + Fe-chelated-n fertilizer treatment. The highest essential oil percentage was in NPK-n + Fe-chelated-n. The highest mucilage percentage was observed in NPK-s + NPK-n + Fe-chelated-n fertilizer treatment, which was not statistically different to NPK-n + Fe-chelated-n treatment. The combined effects of winter cultivation and NPK-n + Fe-chelated-n fertilizers resulted in improving antioxidant activity traits. Overall, the results indicated that the combination of winter cultivation and NPK-n + Fe-chelated-n fertilizers are the most appropriate treatment to acquire highest qualitative and quantitative yield of Dragon’s head, in the Azerbaijan region (Iran).
