A substrate culture experiment was conducted to study the effect of different biological organic fertilizer levels (control: zero fertilization, low level, medium level and high level) on plant growth and yield of Chinese kale (Brassica alboglabra Bailey). Results showed that compared with control, treatments of medium and high fertilization increased the leaf number, plant height, stem diameter, yield and plant dry matter of Chinese kale. Thus they promoted plant growth. The fertilizer utilization ratio of Chinese kale was the lowest for low fertilization treatment, and it was the highest for medium fertilization treatment, while it was decreased for high fertilization treatment. The treatment of medium level fertilization (30g/plant) promoted plant growth and increased the yield of Chinese kale; also it had the highest fertilizer use efficiency. So it was the appropriate organic fertilization amount for Chinese kale production.

Abstract Background Lime-induced iron deficiency in Pea plants is a major nutritional disorder causing severe plant growth and yield reduction in calcareous soils of Tunisia. Other the chemical fertilization for iron chlorosis correction, the exploration of the genotypic differences in response to this constraint remains the most efficient approach due to its coast, environmental benefits, and sustainability. This approach allows as to screen tolerant genotypes and identify useful traits of tolerance. Results calcareous-induced iron deficiency reduced SPAD index, plant growth, net photosynthesis, and tissues Fe concentration against a significant stimulation of the oxidative stress indicators, H2O2 and Malondialdehyde (MDA). In the same time, we have reported significant induction of SOD activity in shoots and CAT activity in roots of the genotype Alexandra (ne clear behavior observed in the other genotypes). Fe use efficiency increased on calcareous soil and clearly discriminates the studied genotypes. Conclusion Genotypic differences were observed, and Alex was found to be the most tolerant. This genotype protect its tissues against oxidative stress by stimulating SOD activity in shoots and CAT içn roots, and expressed significant efficiency of Fe uptake and use on calcareous soil. The Fe use efficiency for photosynthesis and for SOD and CAT activities clearly discriminates the studied genotypes and can be used as a useful trait for further screening programs.

Ammonium And Nitrate Ratios

The effect of different ammonium and nitrate ratios (NH4+-N : NO3--N = 0:100, 25:75, 50:50 and 75:25) on growth and yield of Chinese kale (Brassica alboglabra Bailey) with 3 cultivars were studied in hydroponics. The results indicated that, compared with the complete nitrate treatment, plant height, stem diameter and biomass of Chinese kale were increased in the low enhancement of ammonium (25%) in nutrient solution, while plant growth and biomass were decreased in the medium (50%) and high (75%) enhancement of ammonium. Ammonium enhancement treatments increased the root/shoot ratio of Chinese kale. Low enhancement of ammonium (25%) in nutrient solution had no significant effect on root activity of Chinese kale, while it was decreased by the medium (50%) and high (75%) enhancement of ammonium treatments. Nutrient solution with 25% ammonium enhancement maintained a high root absorption capacity and increased plant biomass, so it was appropriate to hydroponics for Chinese kale.

The Impact

Phosphorus (P) is an essential macronutrient necessary for plant growth, development, and reproduction. Two field experiments were carried out in 2018/2019 and 2019/2020 on P-deficient soil to evaluate the impact of foliar fertilization with nanophosphorus (nP) on growth, yield, and physio-biochemical indices, as well as trigonelline content of fenugreek plants under deficient irrigation (dI) stress (a deficit of 20 and 40% of crop evapotranspiration; dI-20 and dI-40). The growth and yield traits, leaf integrity (relative water content and membrane stability index), photosynthetic pigment contents, leaf and seed P contents, and stem and leaf anatomical features significantly decreased under dI-20, with greater reductions recorded under dI-40. In contrast, water-use efficiency, osmoprotective compounds, including free amino acids, soluble sugars, proline, and trigonelline, along with antioxidant contents (ascorbate, glutathione, phenolics, and flavonoids) and their activity increased significantly under both dI-20 and dI-40. However, foliar feeding with nano-P considerably increased plant growth and yield traits, leaf integrity, photosynthetic pigments contents, leaf and seed P contents, and anatomical features. Besides, water-use efficiency, osmoprotectant contents, and antioxidant content and activity were further increased under both dI-20 and dI-40. The positive effects were more pronounced with the smaller nP (25 nm) than the larger nP (50 nm). The results of this study backed up the idea of using foliar nourishment with nP, which can be effective in modulating fenugreek plant growth and seed production.

The multiple factors constraining the growth, reproduction, and survival of diverse organisms are often non-additive. Research of interacting factors generally involves conceptual models that are specific for target organism, type of stress, and process. As a complement to this reductionist, bottom-up view, in this review I discuss a quantitative top-down approach to interacting stresses based on co-limitation theory. Firstly, co-limitation theory is revised. Co-limitation is operationally identified when the output response of a biological system (e.g. plant or population growth) to two or more inputs is greater than its response to each factor in isolation. The hypothesis of Bloom, Chapin, and Mooney, that plant growth is maximised when it is equally limited by all resources, is reworded in terms of co-limitation and formulated in quantitative terms, i.e. for a given intensity of aggregate stress, plant growth is proportional to degree of resource co-limitation. Emphasis is placed on the problems associated with the quantification of co-limitation. It is proposed that seasonal indices of nitrogen and water stress calculated with crop simulation models can be integrated in indices accounting for the aggregated intensity of water and nitrogen stress (SWN), the degree of water and nitrogen co-limitation (CWN), and the integrated effect of stress and co-limitation (SCWN = CWN/SWN). The expectation is that plant growth and yield should be an inverse function of stress intensity and a direct function of co-limitation, thus proportional to SCWN. Secondly, the constraints imposed by water and nitrogen availability on yield and water use efficiency of wheat crops are highlighted in case studies of low-input farming systems of south-eastern Australia. Thirdly, the concept of co-limitation is applied to the analysis of (i) grain yield responses to water–nitrogen interactions, and (ii) trade-offs between nitrogen- and water-use efficiency. In agreement with theoretical expectations, measured grain yield is found to be proportional to modelled SCWN. Productivity gains associated with intensification of cropping practices are interpreted in terms of a trade-off, whereby water-use efficiency is improved at the expense of nitrogen-use efficiency, thus leading to a higher degree of resource co-limitation.

The experiments was conducted at Kasang village, district of Batang Anai, Padang Pariaman regency during June until December 2013. The objectives of this experiment was to increased lowland rice production through specific location of nutrient management (SLNM) on low potential productivity of lowland. Four packages of fertilization such as Package A, B, C and D were arranged in Randomized Completely Block Design (RCBD) with 6 replications. Result of this experiment showed that; (1) SLNM treatments were significantly affected plant growth such as tiller number and plant high. Saveral of yield components also significantly affected by SLNM treatments packages such as panicles number, number of seeds per panicle, and percentage of filled grains. SLNM package A, B, and C significantly increased grain yields such as 24.9%,  34.2%, and 29.5% respectively compred to farmer package (Package D). The low grain yield with Famer package caused insufficient nutrient supplied for plant growth and yield is due to low fertilizer application and inaccurate nutrient management. The experiment suggested that the best application of inorganic fertilizer should be followed or combined with organic fertilizer such as animal manure or compost and  the application of thus material should be in mature condition. Key Words:  rice, specific location, fertilizer

Comparing to other schools in Aceh, the school has a good quality, in this case middle ability of the grade students, than others. The experimental design both qualitative and quantitative approaches, in order to investigate students’ abilities to solve word problems. There are two groups, namely, experimental group which using realistic mathematics education (RME) approach in instruction , and another group without using RME in instruction. in the case using instrument, both groups used the same instrument in this research. Moreover, eksperimental case research Pre-test Post-test Control Group Design was used, in order to investigate differences between student who has ability to solve word problem by using RME approach and student who get instructions without RME approach and so to know interaction between students ability to solve word problem by mathematics realistic. The investigation based on the level ability mathematics students (high level, medium level and low level), and to see students’ attitude toward mathematics realistic. Based on data analysis, it is found that a differences of students abilities between experimental group and control group. The differences of the abilities shown by statistics test by anova test (by using α = 0,05). It means that there are differences of students’ abilities to solve word problems using RME and students’ ability to word word problems using conventional learning as learning instructions.therefore, there is no interaction between students’ abilities in order to solve word problems in RME based on students’ abilities (high level, medium level and low level) and students’ attitude toward RME approach.

Yield Responses

Nutrient availability affected plant growth and yield. This study aimed to examine the effect of interval application and fertigation frequency toward plant growth and yield, and further determined the most proper fertigation interval and frequency that support the highest plant growth and yield. Experiment was arranged in Split plot randomized Completely Block Design. The main plots were interval of nutrient application, i.e., 3 days interval, 6 days interval, 9 days interval. The sub plots were the frequency of nutrient application, i.e., once/day, 2 times/day, 3 times/day. The plot size for each treatment was 2.5 m×1.3 m and plant spacing was 15 cm×20 cm. Space between beds was 1 m. Red onions (Bima variety) were planting in a raised bed covered with silver black polythene mulch. Before planting, 5 ton/ha manure and 1 ton/ha lime were mix with the soil. Fipronil 1.5% was applied with dose 8 kg/ha to control grubs. Nutrient was mixture between liquid organic fertilizer (7.5 mL/L), rabbit urin (5mL/L) and AB Mix (7.5 mL/L A+7.5 mL B). The nutrient was dispensed 150 mL/plant according to treatment using fertigation system operated remotely using Internet of Things. The nutrient was given from 14 DAP (Days After Planting) until 68 DAP. Irrigation water was dispensed 150 mL daily in the same way. The interval of fertigation significantly affected the growth of red onion (plant height, number of leaves and number of yield). Three days interval of nutrient supply resulted in the tallest plant, highest number of plant leaves, and highest number of bulbs. However, the frequency of nutrient supply daily significantly affected the yield of red onion. The application of nutrient three times/day provided the highest yield (economical dry weight). Further research to examine the effect of fertigation of red onion quality is required.
