Expected climatic changes likely elicit serious challenges for crop production. Therefore, it is indispensable to investigate the response of crop growth parameters and yield under temperature variability environments. The current experiment on chilli pepper growth was conducted in a field, rain-shelter plastic house, and plastic greenhouse, with accumulated temperatures of 2832 °C, 2967 °C, and 3105 °C in 2017; and 2944 °C, 3091 °C, and 3168 °C in 2018 growing seasons. Based on soil analysis, 132.7 kg ha−1 (1× of livestock manure compost as an optimum and 265.4 kg ha−1 (2×) as a double amount of organic matter were applied to each simulated temperature condition. The results showed that organic manure application favorably affects the growth attributes and nutrient uptake of chilli pepper with the highest values found in the plastic greenhouse, followed by the rain-shelter house, over the open field cultivation condition. The highest growth of chilli pepper was at the 2× rate of organic manure application, whereas the highest yield was found at the 1× rate of organic manure application. The application of organic manure at the 1× rate in the greenhouse increased root, shoot, and fruit dry weights of chilli pepper by 21.4%, 52.4%, and 79.7%, respectively, compared to the control values. These results indicate that the rational use of organic amendments might be the best solution for chilli pepper production under variable climate conditions.

The highly calcareous soil limits plant growth parameters due to inadequate uptake of plant nutrients. Calcareous soil conditions affect plant growth through impaired chlorophyll synthesis, root growth, enzyme synthesis, and nutrient uptake. To overcome the negative effect of calcareous soil, six bacterial strains namely Alcaligenes 637Ca, Agrobacterium A18, Staphylococcus MFDCa1, Staphylococcus MFDCa2, Bacillus M3, and Pantoea FF1 were inoculated in one-year-old plants of peach cultivar ‘Elegant Lady’ grafted onto GF677 and Nemaguard rootstocks. The bacterial treatments were observed to improve plant growth and nutrient content compared to the control. Moreover, the GF677 rootstock was observed to be more tolerant to high calcareous soil conditions than Nemaguard, showing better plant growth and nutrient content. At the Nemaguard rootstocks, the largest leaf area was observed to be upon inoculation with MFDCa2 (29.1 cm2), FF1 (28.8 cm2), and M3 (28.1 cm2), whereas at the GF677 rootstock, the highest leaf area was observed upon inoculation with MFDCa1 (34.7 cm2), FF1 (32.6 cm2), and 637Ca (31.5 cm2). The leaf iron content was higher in bacterial treatments than the control. In the Nemaguard rootstock, the highest iron content was measured in plants inoculated with 637Ca (133.49 mg kg–1) and M3 (127.64 mg kg–1), whereas in the GF677 rootstock, the treatments MFDCa1 (131.51 mg kg–1), 637Ca (131.21 mg kg–1), FF1 (127.72 mg kg–1), and M3 (127.68 mg kg–1) resulted in high iron content. The results indicate that bacterial inoculations have a significant potential to improve plant growth and can be used as biofertilizers for peach grafted onto Nemaguard and GF677 in high calcareous soil conditions.

<p>Pak Choy or Bok Choy (<em>Brassica rapa </em>L. var. chinensis) is one of favorite Chinese leafy vegetable for various dishes in Indonesia. In this study, it was used as a plant model to identify the appropriate organic hydroponic nutrient solution for leafy vegetable seedling production. The seed was sown on rock wool slabs submerged with 200 ml of a nutrient solution containing biofertilizer of <em>Beyonic StarTmik@Lob</em> (0, 25, 50, 75, and 100%). commercial hydroponic solution (0, 25, 50, 75, and 100%) and its combination (25, 50, and 75%). The experiments were arranged in a CRD. Meanwhile, the obtained data was analyzed using ANOVA followed by DMRT. The relationship among growth parameters was observed using Pearson correlation analysis.  The result of the study showed that the combination of organic and inorganic nutrient (25% <em>Beyonic StarTmik@Lob</em> and 75% commercial hydroponic solution) resulted in the highest seedling growth parameters and leaf indices as well as the perfectly positive correlations among growth parameters. This result indicated that the use of organic nutrient alone was not appropriate for hydroponic seedling production of Pak Choy. Therefore, further study needs to be done to identify the hydroponic solution without inorganic nutrients towards the organic vegetable production.</p>

A field trial was conducted at the Experimental Farm of the University of Benin, Benin City, Nigeria between May and July in both 2015 and 2016 to evaluate growth and yield responses of cucumber (Cucumis sativum L.) to different nitrogen levels of goat manure. The experiment was laid out in a randomized complete block design involving five treatments and replicated three times. The treatments were cured goat manure applied at levels of 0, 100, 200, 300 and 400 kg N ha-1. Growth parameters were collected on vine length (cm), vine girth (cm), number of branches, number of leaves and leaf area index (LAI). Yield parameters assessed were fruit length (cm), fruit girth (cm), number of fruits per plant and fruit yield (t ha-1). Goat manure application significantly (P < 0.05) influenced growth parameters positively, which led to the enhancement of the fruit yield. Goat manure application levels of 200 (20.85 t ha-1), 300 (20.85 t ha-1) and 400 (26.21 t ha-1) kg N ha-1 had similar (P > 0.05) fruit yield, but significantly (P < 0.05) higher than those of 0 (12.34 t ha-1) and 10 (16.96 t ha-1) kg N ha-1. It thus recommended that goat manure at 20 kg N ha-1 is more appropriate for cucumber production in the humid ultisols environment.

Foliar application of micronutrients has become a common farm management practice to increase the overall yield of various crops. However, the effects of foliar fertilization on shelf life and postharvest quality of the crops are rather under-researched. The aim of this field experiment was to evaluate the effect of foliar application of individual mineral nutrients (calcium (Ca), zinc (Zn), manganese (Mn), and iron (Fe) on pre and postharvest quality of broccoli. The broccoli plants were subjected to single foliar sprays of either Ca, Fe, Zn, or Mn, which was repeated four times during plant growth at a 1 g/kg concentration. Once harvested, the broccoli heads were refrigerated at 4 °C for 28 days. Our results indicated that foliar application of Ca, Zn, Mn, and Fe did not have a significant effect on plant growth parameters, apart from enhancing Soil Plant Analysis Development (SPAD) chlorophyll meter values. However, during postharvest, foliar application treatment showed a positive response on weight loss during storage and reduction in yellowing of the broccoli heads. Foliar treatments increased the concentration of Nitrogen (N), Phosphorus (P), Ca, Zn, Mn and Fe significantly in the broccoli head tissue. Total chlorophyll content, total phenolic compound, ascorbic acid, peroxidase activity, glucoraphanin and glucobrassicin and flavonoids were significantly increased by all foliar treatments. Crude protein content and sulforaphane were enhanced by Ca and Mn treatments. Overall, foliar application of the investigated mineral nutrients may prove beneficial in improving the shelf-life and nutrient content of broccoli during postharvest handling and storage.

During my research, I studied the 0.01 M CaCl2 extractable NO3--N, NH4+-N, Norg, P and K contents of the soil samples originated from a long term fertilisation trial in the experimental site Hajdúböszörmény. Relationships among the soil nutrient contents, the agronomic nutrient balances of the 2009 year, and fertilization were studied. From the results of the study it was concluded as follows:– Fertilization significantly increased the CaCl2 extractable NO3--N, NH4+-N, and K contents of soil.– Norg fraction increased as a function of the increasing yield. Hence, it can be assumed that the greater the produced yield, the more the stubble and root residues remain on the arable land. These organic residues can result significant increase in the Norg content of soils.– The CaCl2 extractable P and K contents were compared with the calculated P and K limit values. According to these, the experimental soil has a good phosphorus and lower potassium supply capacity. These results are in accordance with the results of the conventional Hungarian fertilization recommendation system.– It can be stated that the 0.01 M CaCl2 is able to determine not just inorganic N forms but Norg fraction as well that characterize the easily mineralizable nitrogen reserves. The results proved that AL-P and -K (ammonium lactate acetic acid, traditional Hungarian extractant) are in good agreement with the P and K reserves, but it is important from the aspect of environmental protection and plant nutrition to measure the easily soluble and exchangeable K-, and P-contents of soil. 0.01 M CaCl2 method is recommended for this.

A field experiment was conducted in Khulna district to evaluate the growth and nutrient composition on stem Amaranth by irrigating with different water sources. Water that has been used as treatment are saline water, T1 and treated water, T2 (water from a project called Managed Aquifer Recharge (MAR)). A field condition was also included, T0 (control). All the growth parameters of the crop were significantly improved for treated water. Whereas, N, P, and K uptake (3.54, 39.56 and 564.42 kg/ha, respectively) were increased and S was decreased (48.76 kg/ha) for treated water (T2) compared to control (T0). Carbohydrate and total dietary fiber (TDF) is increased (6.09 and 6.87 g/100g) while protein, fat, ash and energy in the leaf of stem Amaranth is decreased (3.16, 0.46, 3.26 g/100g and 54.94 Kcal/100g respectively) by irrigating with T2 water. Moreover, carbohydrate content is increased (3.55 g/100 g) in treated water (T2) but protein, fat, ash, TDF and energy in the stem of stem Amaranth is decreased. EC, pH, Na, K, Ca and Mg of the soil were decreased markedly by applying treated water (T2) and other nutrients present in soil also varies. From the study, it can be concluded that the best alternate source of water for irrigation is MAR water (T2) which can improve plant nutrient content and uptake and soil nutrient status.Bangladesh J.
