P Fertilizers

There is no alternative to phosphorus (P) in agriculture as it is second most important plant nutrient after nitrogen. Mineral P fertilizers are derived from rock phosphate (RP) which is finite, non-renewable and geographically restricted to a few countries, thus its shortage likely affects agriculture in near future as the world population is growing at a greater pace. This could increase P inputs in agriculture in order to meet rising food demands which may result in the depletion of RP reserves. Furthermore, P losses from farmlands in case of mineral P fertilizers also demands the sustainable use of P not only because of its finite resources but also the environmental concerns associated with P fertilization such as eutrophication. The present study was designed to formulate biochar-based P fertilizer that would help in the sustainable use of P fertilizer. Biochar(s) were prepared using wheat straw at 350–400 °C pyrolytic temperature followed by enrichment with Di-ammonium phosphate (DAP) taking into account all possible combination of DAP to biochar on the w/w basis (0:100, 25:75, 50:50, 75:25 and 100:0). Enrichment was carried out using two different methods i.e., phosphorus enriched biochar (PEB1) by hot method and cold method (PEB2). An incubation experiment was performed to assess the impact of each biochar on selected properties of soil. The treatments were organized in factorial arrangement under complete randomized design (CRD) with three replications. Both the amendments were applied at rate of 1% of dry soil on a w/w basis. A significant increase in soil extractable P and total nitrogen (N) was recorded for the ratio 50:50 as compared to control as well of rest of treatments. Similarly, high organic contents were found for both PEB1 and PEB2 at the ratio 50:50. An incubation experiment was followed by pot trial using 50:50 for both PEB1 and PEB2 and split doses of recommended P were applied (0%, 25%, 50% and 100%) with a control under CRD with three replications using chickpea as test crop. Both PEB1 and PEB2 with 50% P have significantly improved crop growth, yield, nodulation, and plant physiological and chemical parameters as compared to a recommended dose of P alone. The result may imply that the integration of P-enriched biochar and chemical fertilizer could be an effective approach to improve chickpea production and soil properties.

Biochar Amendment

Soil acidification is a serious challenge and a major cause of declining soil and crop productivity in the Eastern parts of South Africa (SA). An incubation experiment investigated effects of different maize residue biochar rates on selected soil properties and soil loss in acidic Hutton soils. Biochar amendment rates were 0%, 2.5%, 5%, 7.5%, and 10% (soil weight) laid as a completely randomized design. Soil sampling was done on a 20-day interval for 140 days to give a 5 × 7 factorial experiment. Rainfall simulation was conducted at 60, 100 and 140 days after incubation to quantify soil loss. Relative to the control biochar amendments significantly improved soil physicochemical properties. After 140 days, biochar increased soil pH by between 0.34 to 1.51 points, soil organic carbon (SOC) by 2.2% to 2.34%, and microbial activity (MBC) by 496 to 1615 mg kg−1 compared to control. Soil aggregation (MWD) changes varied from 0.58 mm to 0.70 mm for the duration of the trial. Soil loss significantly decreased by 27% to 70% under biochar amendment compared to control. This indicates that maize residue biochar application has the potential to improve the soil properties and reduce soil loss in the degraded acidic Hutton soil.

The Impact

Water scarcity is a global problem, which leads to unprecedented pressure on water supply in arid and semi-arid regions. Treating wastewater is an alternative and valuable water resource, therefore its reuse for agricultural irrigation has been growing worldwide since the beginning of the 21st century. In several regions of the wine-producing countries subject to significant water stress (e.g., Australia, California-USA, Spain), wastewater recycling appears to be the most accessible alternative, both financially and technically, for the agricultural uses that notably not requiring drinking water. Therefore, this research was planned to quantify the contribution of treated wastewater (TWW) to fertilization-needs of the vine, evaluate the impact of irrigation with TWW on the soil, vegetative growth, yield, and wine and grape juice composition. The results provide scientific and technical knowledge on a strategy of water management with high added value. The fertilizer contribution of the TWW would be important, according to the plant's nutrient needs (e.g., in this study 19–39 Unit N, 0.5–1.1 Unit P and 14–28 Unit K ha−1 were supplied with TWW). Ensuring treated wastewater microbiological quality is essential, but without reducing of its nutrients. These nutrients would be a valuable input for crop growth and yield, and could reduce the need to resort for inorganic/synthetic fertilizers. A sustainable use of treated wastewater over the long term would, however, necessitate a good practice guidelines and an integrated vision of treated wastewater quality, crops, irrigation and post-harvest practices.

P Fertilizers

Phosphorus (P) is an important macronutrient affecting the growth and yield of all crop plants. Plants absorb P from the soil solution as inorganic phosphate (Pi). More than 70% of the arable land is deficient of Pi which demands the supply of an external source of synthetic P fertilizers to improve the yields. The P fertilizers are manufactured from non-renewable rock phosphate reserves which are expected to be exhausted within the next 100-200 years. This poses a great threat to food security since it is very difficult to meet the food production caused by increasing world population without the supply of an adequate P fertilizer. Several efforts have been made in the past decade to understand the mechanism of Pi uptake and its redistribution in plants. In this mini-review, we discuss the details on possible strategies to combat the crisis caused by loss of phosphate rock reserves and to improve the crop yield without much dependency on external P fertilizer. Approaches such as application of functional genomics studies to manipulate the expression levels of key transcription factors and genes involved in low Pi stress tolerance, molecular marker-assisted breeding to develop new varieties with improved yields under Pi-deficient soils and to recapture the Pi released in wastewaters for recycling back to the farm lands, will help improve the crop production without depending much on non-renewable P fertilizers and will also aid for the sustainable food production.

The Impact

A pot experiment was set up using completely randomized design (CRD) to compare the influences of different commonly available organic manures in the markets of Dhaka, Bangladesh on the growth parameters and nutrient contents in Mint plants (Mentha sp.). Eight different manures were used as treatments for the comparison, viz. ACI, Alo, Annopurna Vermicompost, Cow dung, Kazi, Mazim, Modern Vermicompost and Trichocompost GBD, along with a control, taking three replications of each treatment. After 2.5 months (75 days) the plants were harvested. Trichocompost GBD showed the highest average number of leaves (130.33 plant-1), plant height (27.67 cm plant-1), number of branches (11.00 plant-1) and number of stolons at harvest (1.67 plant-1). The maximum average single leaf area (2.01 cm2 plant-1) and fresh weight (1.68 g plant-1) were observed in Kazi. ACI was observed to have the highest dry weight (0.26 g plant-1), whereas cow dung had the longest root (8.57 cm plant-1). Nutrient accumulation in leaf and stem exhibited the highest N in ACI, highest P and K in Alo, and highest S in Kazi. Correlation analysis of the explored traits with nutrient concentration of plant shoots was performed to elucidate the impact of plant nutrient contents on the analysed parameters. J. Biodivers.

Tuber Specific Gravity

Potato is one of the main crops grown worldwide under different climatic conditions. Potato is conventionally produced under intensive tillage practices under the same or different soil types. Research has shown some contrasting effects of the tillage practices on the soil properties, crop growth, yield, and quality. Under the reducing available freshwater for food production, soil management practices are more targeting conservation and system sustainability. It is therefore critical to revisit literature on the tillage practices and their impact on the soil, crop, and crop yield. This review presents research results of studies conducted exclusively on potatoes comparing different types of tillage practices and is a valuable source of information for potato growers and scientists as it is not only focused on the impact of tillage practices on soil properties but also on potato tuber yield and grade, tuber specific gravity, and the impact of tillage practices on diseases in potatoes.

The Impact

Coriander is an important herb & seed spice. The yield of coriander is influenced by the agronomic practices adopted during cultivation. This study was carried out in the Department of Plantation Crops and Spices, College of Horticulture, Vellanikkara, Kerala Agricultural University from July 2019 to March 2020 to analyse the effect of seed treatments, spacing and growing season on yield and quality of coriander leaves under rain shelter. The experiment was laid out in factorial completely randomized design (FCRD) with three replications. The study revealed that, presowing seed treatments improved the growth and yield of coriander than untreated seeds. The impact of seed treatments was conspicuous at the time of harvest on growth, yield and quality parameters. Hydropriming for 24 h was found to be the best presowing seed treatment followed by seed treatment with GA3 50 ppm for 8 h. A closer spacing of 10 x 10 cm which accommodated more plants per unit area recorded the highest biomass and herbage yield plot-1. October – December season was found to be the best for obtaining better growth and yield in leaf coriander. Hence, the study concluded that, hydropriming for 24 h or seed treatment with GA3 50 ppm for 8 h, a closer spacing of 10 x 10 cm and October – December season are the ideal combination for the best performance of variety CO-4 for leaf purpose under rain shelter in the tropical moist humid climate.

The main purpose of this study was to examine the impact of different phosphorus (P) fertilizers and organic manures alone and in combination with Bacillus sp. MN-54 on growth, yield, nutrient uptake, chlorophyll (SPAD value) and crude proteins content of chickpea. The simple manure (SM), processed manure (PM), single super phosphate (SSP), and rock phosphate (RP) were applied individually and in different combinations to the soil in pots, and the chickpea seeds treated with Bacillus sp. MN-54 were sown in the selective pots. Results showed that individual use of SM, PM, SSP, RP, and strain MN-54 significantly increased (P ≤ 0.05) the nutrient uptake, growth, yield, and protein content of chickpea as compared to control treatments. While the combined use of SM or PM, SSP or RP, and MN-54 further enhanced this effect. Among different treatments, combined use of RP, PM and MN-54 proved the most effective treatment showing increase of 37.5 and 42.6% in shoot and root lengths, 43.4 and 38.3% in fresh and dry shoot weights, 36.1 and 36.5% in fresh and dry root weights, 45.8% in no. of pods, 43.6% in nodules counts, 16.0% in 100-grain weight and 31–36% nutrient uptake over control treatments. Our findings suggest that the co-addition of organic manures and P fertilizers along with plant growth promoting bacteria (i.e., Bacillus sp. MN-54) not only increases the growth and yield but also improves nodulation, nutrient uptake, and crude proteins content in chickpea.
