The objective of the present study was to verify the effect of two doses of the biofertilizer ‘Supermagro’ applied in cover, in the presence and absence of cured bovine urine in the maize crop, and in the soil penetration resistance, as well as the effect in the application of biofertilizer ‘Fert Bokashi’. The experimental design used was of randomized blocks with four replicates. The treatments constituted of cover application of ‘Supermagro’ in the dose of 6% (recommended dose) (T1); cover application of ‘Supermagro’ in the dose of 12% (T2); cover application of ‘Supermagro’ in the dose of 6% + cured bovine urine 3% (T3); cover application of ‘Supermagro’ in the dose of 12% + cured bovine urine 3% (T4); cover application of cured bovine urine 3% (T5); use of the biofertilizer ‘Fert Bokashi’ in the dose of 0,5% of dilution) (T6); and control (T7). The results obtained were tabulated and submitted to analysis of variance and the comparison of means by the Dunnett test at 5% of probability, with the aid of the statistical analysis software SAS. For the parameters: thousand grain mass, the treatment ‘Fert Bokashi’ alone presented the highest thousand grain mass (375,00 g) being it superior to the control (p<0,05) with 360,94 g. For the yield parameter, the treatments ‘Supermagro’ 12% + urine, bovine urine alone and ‘Fert Bokashi’ presented the highest averages, (5961 kg ha-1, 5512 kg ha-1 and 5808 kg ha-1, respectively) which differed statistically from the control (5500 kg ha-1) (p<0,05). The biofertilizers are an alternative to increase the yield of maize in the organic system with an average increase of 20% in the maize production in relation to the area without application. The biofertilizer ‘Fer Bokashi’ is an alternative to increase maize yield in the organic production system. The application of biofertilizers did not influence in the soil penetration resistance.

Reduction Effect

Agricultural soils can be affected in their ecological functions by in-field traffic of agricultural machinery. A three-factorial research design was carried out in a field experiment to test the effect of slurry tanker filling level (filled, half-filled, empty), tire inflation pressure of the slurry tanker (high: 300 kPa, low: 100 kPa), and ground covering (+cover crop, −cover crop) on tire track and soil penetration resistance (averaged, 0–20 cm, 21–40 cm) after application on the fields in spring. Additionally, the effect on grain yield of the subsequent culture was considered. The total weight of the tractor slurry tanker combination was 16,470 kg (empty), 25,940 kg (half-filled), and 34,620 kg (filled). The low tire inflation pressure of the slurry tanker increased the mean tire–soil contact area by 75% (filled), 38% (half-filled), and 16% (empty tanker). The results obtained show a significant effect of tire inflation pressure and ground covering on the measured parameters. The tire inflation pressure reduction effect on track depth was highest in the filled slurry tanker (−17.8%). With increasing wheel load, the effect of reduced tire inflation pressure on soil penetration resistance (0–20 cm) increased. In the subsoil (21–40 cm), the effect of tire inflation pressure was much lower, indicating that a reduction of tire inflation pressure preserves the upper layers rather than the lower ones. Furthermore, cover crops are linked to a higher degree of soil deformation after traffic with the tractor–slurry combination due to their loosening effect on the topsoil. Tire tracks were 15.0% deeper in the cover crop field than in the field without a cover crop. It is assumed that cover crop mixtures with different types of root mass can influence the mitigation of soil compaction in an ameliorative way.

This study aimed to determine the effect of vertical mulching to minimize of runoff and soil erosion, vertical mulching influence on the growth and yield of maize, and the correlation between erosion and runoff to maize yield in vertical mulching. This study was conducted in March and July 2012 in the village of Bulontala, District of South Suwawa, Bolango Bone regency, Gorontalo province with slope +15%. This study uses a randomized block design (with three treatment levels: (a) P0 control, (b) P1 (vertical mulching with length 1 m, width 0.5 m and the 0.4 m), and (c) P2 (vertical mulch with 1 m long, 0.5 m wide and 0.5 m in). Each treatment was repeated 3 times in order to obtain experimental plots 9 unit. Observation parameters include surface runoff, erosion, plant growth and the production of maize. Data was analyzed using analysis of variance with the help of SAS data processing program. P1 treatment because runoff and soil erosion are markedly lower (surface flow of 108.19 m3 ha-1 and the erosion of 683.0 kg ha-1). P1 treatment significantly affected the growth of stem diameter (2.21 cm) and increased production of dry shelled maize crop (3.28 ton ha-1). Surface flow is positively correlated with erosion and runoff and erosion negatively correlated with maize production.

Abstract Crop productivity evaluation with models simulations can help in the prediction of harvests and in the understanding of the interactions resulting from the soil-plant-atmosphere continuum. The aim of this study was to calibrate and validate the AquaCrop model for maize crop in the edaphoclimatic conditions of Campos Gerais region, Paraná State, Brazil. The analyses were carried out for maize crop with model input data (climate, crop, soil and soil management) obtained from the ABC Foundation Experimental Station in Castro, Ponta Grossa and Socavão. The climate in the region is humid subtropical, with rainfall evenly distributed. The relief varies from flat to gently undulating. The period analyzed in the calibration and validation process comprised 2011 to 2016 and 2012 to 2016 harvests, respectively. The data used in the calibration of AquaCrop was different from those used in the validation process. Observed and simulated yields were evaluated by simple linear regression analyses, absolute and relative errors, correlation coefficient (r), concordance (d) and performance (c) indexes. The calibration of AquaCrop was satisfactory in the locations studied for maize crop, obtaining absolute errors varying from 6 to 121 kg ha–1. The highest calibration errors occurred in Castro. However, the errors were not enough to reduce the performance in the validation process for this localitie. The model validation resulted in “excellent” performance in all locations evaluated. The AquaCrop can be used to predict the maize yield with acceptable accuracy in the Campos Gerais Region, Paraná State, Brazil.

N Release

Commonly N release from legume residues is rapid in the tropics. Legume mixtures with grasses can result in slower nutrient release from residues, better matching the N requirements of the following crop. The objectives of this study were to evaluate the effects of the green manures sunnhemp (Crotalaria juncea) and millet (Pennisetum glaucum), alone or mixed, on the performance of a subsequent maize crop with and without the application of N-fertilizer. The experiment consisted of four randomized blocks, with split plots. The plot treatments consisted of previous cultivation of sunnhemp, millet, mixed sunnhemp+millet and weeds. The subplot treatments were 90 kg N ha-1 and absence of N-fertilizer. Substantial amounts of biological nitrogen fixation (BNF) nitrogen were present in above ground parts of sunnhemp alone (173 kg ha-1) and mixed with millet (89 kg ha-1). Decay rates showed that half of the N was released 15 and 22 days from sunnhemp and sunnhemp+millet residues, respectively. The difference was attributed to temporary immobilization due to the higher C/N ratio of sunnhemp+millet. The preceding sunnhemp+millet treatment resulted in a larger maize yield than sunnhemp alone, when no N-fertilizer was applied. This effect was not observed when N-fertilizer was added. This effect may be due to a more timely N release, compared to sunnhemp and millet alone, when available N is required for maize. Nitrogen budgets showed that 15% and 10% in maize grain N was recovered from BNF for sunnhemp alone and sunnhemp+millet respectively. The recovery of N-BNF by maize was 65% higher after sunnhemp+millet than after sunnhemp monocrop.

Smallholder farmers influenced from the challenges of production constraints to afford farm family with surplus food. To improve this problem the present study was designed to evaluate legume shrubs hedgerow intercropping with maize. In the present study, the growth performance of Sesbania sesban and Cajanus cajan was evaluated to determine their potential in hedgerow intercropping. The result revealed that Sesbania sesban performs better than Cajanus cajan in terms of biomass provision in the successive pruning, mean height, branching, diameter at breast height and root collar diameter. Biomass produced from Sesbania sesban was significantly higher than Cajanus cajan, this plays great role in soil nutrient improvement and maize yield also increased. There was an increasing trend in soil properties in terms of organic C, total N, in legume treatments especially in Sesbania sesban hedgerow to the initial and control soils. Maize grain yield higher under Sesbania sesban hedgerow plot than Cajanus cajan, maize with fertilizer and control. This should be intensively demonstrated to sustain the agricultural production as an organic farming through integration of easily adapting, less competing with the companion crop, deep rooted and fast growing legume tree/shrub species. Further research is important in areas of determining decomposing rate of different parts, pruned biomass and potential species should be identified. Int. J. Agril. Res. Innov.

Abstract Lack of budburst inducers is a major problem in organic production of temperate fruits. This study aimed at evaluating the effect of alternative budburst inducers on kiwifruit vines of cultivar Bruno grown in an orchard in Pelotas, Rio Grande do Sul (RS), Brazil. Inducers efficiency was investigated in both 2016-2017 and 2017-2018 seasons. The first season comprised of ten treatments, which used garlic extract at different concentrations, both, associated with and without mineral oil; Welsh onion extract at different concentrations, both associated with and without mineral oil; just mineral oil; and control (no application). In the second season, evaluation was carried out ith treatments that performed well in the first season, garlic extract atdifferent concentrations associated with mineral oil, just mineral oil and control. The followingvariables were evaluated: budburst percentage, phenology (budburst and flowering), fruit set, number of fruit/plant, fruit mass/ plant, estimate production, mean mass, fruit length and diameter. Results showed that 10% garlic extract + 2% mineral oil induced the highest budburst percentages in both seasons; the position of buds on branches influences budburst; apical buds exhibit the highest budburst percentage; 15% garlic extract causes phytotoxicity to buds; and Welsh onion extract is inefficient to induce budburst.

The relation between climate and maize production in Nepal was studied for the period 1970/71-2007/08. Due to the topographical differences within north-south span of the country, Nepal has wide variety of climatic condition. About 70 to 90% of the rainfall occurs during summer monsoon (June to September) and the rest of the months are almost dry. Maize is cultivated from March to May depending on the rainfall distribution. Due to the availability of improved seeds, the maize yield has been steadily increasing after 1987/1988. The national area and yield of maize is estimated to be 870,166ha and 2159kg/ha respectively in 2007/08. The present rate of annual increase of temperature is 0.04°C in Nepal. Trends of temperature rise are not uniform throughout Nepal. An increase of annual temperature at Rampur during 1968-2008 was only 0.039°C. However, at Rampur during the maize growing seasons, March/April - May, the trend of annual maximum temperature had not been changed, but during the month of June and July, the trend of increase of maximum temperature was 0.03°C to 0.04°C /year.Key words: Climate-change; Global-warming; Hill; Mountain; Nepal; TaraiThe Journal of AGRICULTURE AND ENVIRONMENT Vol. 11, 2010Page: 59-69Uploaded Date: 15 September, 2010

Background: Organic production of cluster bean is to contribute to the enhancement of production sustainability along with ecology. Sustainability in organic farming must therefore be seen in a holistic sense, which includes ecological, economic and social aspects. A synergistic effectof bio fertilizer with crop increases the crop productivity and sustainability also. Bio fertilizers are low cost, effective and renewable sources of plant nutrients to supplement chemical fertilizers. Therfore to overcome the ill effect of chemical based farming, organic system is becoming the emerging need of the society.Methods: A field experiment ’’was carried out in Pusa Navbahar variety of clusterbean during summer season (February to May) of 2019 at College farm, College of Horticulture, Sardarkrushinagar Dantiwada Agricultural University, Jagudan, Dist. Mehsana, Gujarat, India. Sixteen treatments having various combinations of organic sources of nutrients (FYM, vermicompost, and neem cake), bio fertilizers (Rhizobium + PSB + KSM) along with RDF (20/40/0 kg/ha) as a control. They were replicated thrice in a randomized block design having a plot size of 3.0 m × 2.0 m with a spacing of 60 cm × 20 cm. Standard practices were followed during the entire course of the investigation.Result: It showed highly significant differences among different treatments for majority of the growth and yield attributing traits, but treatment T6 (75% N through FYM + Rhizobium + PSB + KSM) was rated as the best treatment for characters like days taken for germination, number of root nodules per plant, plant height at 60 DAS (cm), number of pod per cluster, number of cluster per plant, green pod yield per plant (g), green pod yield per plot (kg) and green pod yield per hectare (kg) as compared to other treatment. It can be concluded that the organic nutrient management in cluster bean with the application of 75% N through FYM + Rhizobium + PSB + KSM is beneficial for obtaining a higher yield.
