Abstract Hungary was one of the main countries in the world as regards the yields reached in maize production. The research was conducted to appraise the effect of NPK fertilizer on traits of different hybrid maize (Fao410, Fao340) at the University of Debrecen and our experiment was carried out in Centre for Agricultural Sciences, Institute of Crop Sciences at Látókép in 2018. NPK fertilizer was applied in six different combinations (0-0-0 control, 30-23-27 first dose, 60-46-54 second dose, 90-69-81 third dose, 120-92-108 fourth dose and 150-115-135 fifth dose kg · ha−1). The result of compound variance showed the level of fertilizer and interaction between fertilizer and genotypes were significant in one percent. Effect of genotypes was a variable level of fertilizer and providing a different yield in the level of fertilizer. The weight of seeds in ear and weight of ear were important traits in the average yield on Fao410 hybrid. Also, the fourth of the fertilizer level was the best level of fertilizer for yield on Fao410 and Fao340. the weight of fresh plant and weight of seeds in ear were highest relation with yield in H340 hybrid. The results of this research can successfully contribute to the science of maize cultivars, the given adapted hybrid to the discovery of their traits and to an application of fertilizers.

We investigated the interaction between genotype by trait, and an experiment was conducted at the University of Debrecen. Two maize cultivars, FAO340 and FAO410, were studied in a randomized complete block design with four replications. This experiment was applied to the six fertilization treatments. Fertilizer levels were NPK0 (control) (N:0, P2O5:0, K2O:0), NPK1 (N:30, P2O5:23, K2O:27), NPK2 (N:60, P2O5:46, K2O:54), NPK3 (N:90, P2O5:69, K2O:81), NPK4 (N:120, P2O5:92, K2O:108), and NPK5 (N:150, P2O5:115, K2O:135). The first principal component showed 54.24%, and the second principal component showed 20.75%, which explained the total squares interaction using the AMMI model in the case of the FAO410 hybrid. As regards the FAO340 hybrid, the first principal component showed 58.18%, and the second principal component showed 18.04%, explaining the total squares interaction using the AMMI model in the FAO410 hybrid. In the GGE biplot on FAO410, the first and the second principal components covered 91.20% of the total data in this analysis. Accordingly, the desirable treatment was NPK5, followed by NPK4, NPK2, NPK3, NPK1, and NPK0. NPK4 and NPK5 had the most desirable treatments for the number of seeds per row, chlorophyll, weight of 1000 seeds, and stem diameter in the case of the FAO410 hybrid.

To determine the effect of Organic-based Fortified Foliar Fertilizer (OFF) on the growth and yield of ‘Lakatan’ banana, this study was conducted at the University of Southeastern Philippines, Tagum – Mabini Campus, Mabini Unit, Mampising, Mabini, Compostela Valley Province, from December 2015 to March 2016.          The experiment was laid out in Completely Randomized Design (CRD) with six treatments replicated three times. The treatments were: T1- control; T2- Recommended Rate of NPK fertilizer/ha; T3 - ½ RR of NPK/ha; T4 –Organic-based Fortified Foliar fertilizer (OFF) at 100 ml/16 liters of water; T5 - ½ RR of NPK + OFF; and T6 - RR of NPK + OFF. Results showed that no significant effects were observed in terms of the plant height at 15, 30, 45 days after application (DAA), pseudostem girth at 15, 30, 45 DAA, and number of hands per bunch. However, significant differences were obtained in the number of leaves, number of fingers per bunch, fruit weight (kg) and yield (tons/ha) of ‘Lakatan’ banana. The highest number of leaves were obtained in T6 – RR of NPK fertilizer/ha + OFF which is comparable to T5 – ½ RR of NPK fertilizer/ha + OFF. T6 – RR of NPK+ OFF also had the highest number of fingers per hand than the rest of the treatments as much as 21% higher than the control. The fruit weight of T6 – RR of NPK+ OFF has 61% higher than untreated and the yield of 37 tons/ha is higher than the national average yield of 9.4 tons/ha in ‘Lakatan’ banana.

Npk Fertilization

Brazil is the third largest corn producer in the world. Despite the country’s position in the maize production ranking, some Brazilian regions have a significantly low maize crop yield, mainly due to lack of management recommendations for it. Thus, the aim of the current study is to evaluate the performance of maize cultivars subjected, or not, to NPK fertilization in Alagoas State hinterland. The experiment was carried out at Federal Institute of Alagoas – Piranhas Campus – from February 2019 to June 2019. It followed a randomized block experimental design at factorial arrangement (5x2), with four repetitions, which totaled 40 experimental plots. The first factor comprised five maize cultivars (BRS Caatingueiro, M274 Morumbi, BRS 2022, Crioula Cateto and AG 1051), whereas the second one encompassed NPK fertilizer application, or not. Fertilization led to the best results in most of the evaluated parameters and to increased grain yield (3,037.7 kg ha-1) in all evaluated cultivars. These outcomes evidenced how the fertilization technique, mainly the one comprising NPK macronutrients, can help increasing yield in maize production systems in Alagoas State hinterland. Among the cultivars evaluated, the hybrid 'AG 1051' was the one that stood out the most, except for the ear insertion height, in all the analyzed variables.

Risk Coping

This paper is aimed at evaluating the factors affecting the concurrent adoption of two risk coping strategies among hybrid maize farmers, namely income diversification supplemented with off-farm work and contract farming in the wake of changing climatic conditions. Climatic changes and food insecurity at the national level have emerged as key risk elements for hybrid maize production due to varying economic conditions. The present paper addresses these risks by examining various sources of risks faced by hybrid maize farmers and develops ideas to tackle these risks. Bivariate and multinomial probit models were employed to analyze numerous factors that influence farmers’ choice of the simultaneous adoption of income diversification (both on and off the farm) and contract farming at the farm level. The results reveal that hybrid maize farmers’ socioeconomic attributes significantly affect their adoption of risk coping tools. Similarly, the climatic, economic (price-related), biological, and financial risk perceptions and risk preference significantly influence the utilization of risk coping strategies in maize production. These outcomes extend our understanding of farmers’ risk preferences and provide parameters for policymakers to forestall diverse risk sources associated with hybrid maize production.

The present study is an attempt to assess the existing agronomic practices of hybrid maize cultivation, its profitability, constraints, and factors affecting hybrid maize production. The majority of the total farmers sowed seeds during the first week of December. The average seed rate was found to be 20.94 kg per hectare. About 16 varieties were found to cultivate by farmers, of which majority farmers used NK-40 followed by Pacific-II. All kinds of fertilizer used by the farmers were below the optimum level of recommendation. About 33 and 28 percent of the total variable cost was for human labour and chemical fertilizer, respectively. The average yield of hybrid maize was found higher than the national average. The average gross margin was observed to be Tk. 28456 on total variable cost basis. The cost per kilogram of maize cultivation was Tk. 4.12 and return from one kilogram of maize production was Tk. 7.80. It is found that the coefficient of human labour, land preparation, irrigation, urea and borax have significantly impact on gross return. Timely non-availability of seeds, high price of fertilizer, and low price of yield were the major problems for hybrid maize production. Farmers cultivated hybrid maize because of higher yield, higher income, and easy growing. Keywords: Gross return; gross margin; profitability. DOI: 10.3329/bjar.v35i1.5869Bangladesh J. Agril.

The Relationship

In most modern societies, nearly every realm of life involves some form of evaluation of our knowledge, abilities and skills. Given the potentially significant consequences of exams, it is not surprising that they are often very stressful. This study aimed to determine the existence and nature of the relationships between level of test anxiety, coping strategies, and achieved success on a mid-term test. As well as examining the direct relations between the given variables, our primary interest was to investigate the potential mediating role of coping mechanisms between the input and output variables of the examined stressful transaction. The study was conducted on a sample of 263 students from the Psychology and German Studies Departments of the Faculty of Philosophy at the University of Novi Sad. According to our results, only emotion-focused coping mechanisms were statistically significant mediators in the relationship between level of test anxiety and mid-term test achievement. The results indicate that students with high test anxiety who employ predominantly emotion-focused coping strategies score lower on a pre-exam knowledge test.

ABSTRACT The excess of salts can affect several processes in the crops, and nitrogen (N) can attenuate the depressive effect of salinity. The objective was to evaluate the influence of nitrogen doses on the growth and gas exchange of corn crop irrigated with saline water. The experiment was conducted from June to September 2019 at the University of International Integration of Afro-Brazilian Lusophony, Redenção, CE, Brazil. The experimental design was completely randomized, in a 2 x 3 factorial scheme (supply water of 0.3 dS m-1 and saline solution of 3.0 dS m-1) and three nitrogen doses, 0, 80, and 160 kg ha-1, corresponding to 0, 50, and 100% of the recommended dose respectively, with six repetitions. At 30 and 45 days after sowing (DAS), plant height, leaf area, number of leaves, photosynthesis, transpiration, and stomatal conductance were evaluated. Saline stress affects plant height, leaf area, photosynthesis, transpiration, and conductance at 30 DAS. The doses of 80 and 160 kg ha-1 provide greater performance in plant height, leaf area, photosynthesis, transpiration, and conductance at 30 DAS. The use of low salinity water and doses of 80 and 160 kg ha-1 were more efficient in terms of plant height, leaf area, photosynthesis, transpiration, and conductance at 45 DAS. The dose of 160 kg ha-1 of N attenuates the harmful effects of salts in AG 1051 hybrid maize plants, providing higher values of photosynthesis, transpiration, and stomatal conductance at 45 DAS when irrigated with water of 3.0 dS m-1.

Determining of the harvest of onion in the peat soil can be done by using physiological harvest criteria, but calculating the appropriate of harvest time can support the quality of harvesting of the onion plant. This study was conducted by using polybags in research and experiment gardens of the Faculty of Agriculture and Forestry of the University of Muhammadiyah Palangkaraya from April to June in 2016. The given fertilization was an organic fertilizer in peat soil by using stall fertilizer like chicken feces with dosages of 15-30 tons ha-1 (PK) and bokashi of stall fertilizer of chicken feces with a dosage of 2-5 tons ha-1 (BK). The observation was done to the calculation of daily temperature (�C), the average of daily temperature (�C), and the unit of heat (heat unit) (�C day) as long as the cultivation of onion plant. The results showed that the harvest time that appropriate to the harvest physiological criteria in the treatment of BK at the age of 57 days after planting is relatively accurate and appropriate because it has a heating unit for 947,17oC day, and the harvest time that appropriate to the harvest physiological criteria of PK treatment at the age of 59 days after planting is relatively late because it has a heating unit for 978,09oC day.
