Soil Testing

Agriculture is the main occupation of our country and it plays a vital role in our country. Using too much of fertilizers may lead to the inferior quality of the crop production. So the measurement of soil nutrients is greatly required for better plant growth. Determining the amount of nutrients in the soil is the key function. pH value is also one of the most important and informative soil parameter to detect the soil fertility and it is measured to identify the soil fertility. In the proposed system, it determines the crops which are suitable for the particular soil type. It will analyze moisture content, temperature and humidity in soil at real time and it will also suggest the crops based on determined PH of soil. This system is proposed to help the farmers to increase the production and the suggestions are made through the mobile application.

Vermiculture is the art, science, and industry of raising earthworms for baits, feeds, and composting of organic wastes. Composting through the action of earthworms and microogranisms is commonly referred to as vermicomposting. Vermiculture is an art because the technology of raising earthworms requires a comprehensive understanding of the basic requirements for growing earthworms in order to design the space and the system by which organic wastes can be processed efficiently and successfully. It is a science because the technology requires a critical understanding and consideration of the climatic requirements, nutritional needs, growth cycles, taxonomy, and species of earthworms suitable for vermicomposting in order to develop a working system that supports earthworm populations to process successfully the intended organic wastes. The nature of the organic wastes also needs to be taken into careful consideration, especially its composition, size, moisture content, and nutritional value, which will eventually determine the overall quality of the vermicomposts produced. The quality of organic wastes also determines the ability of the earthworms to consume and process them, and the rate by which they turn these wastes into valuable organic amendments. The science of vermiculture extends beyond raising earthworms. There are several lines of evidence that vermicomposts affect plant growth significantly. Vermiculture is an industry because it has evolved from a basic household bin technology to commercially scaled systems in which economic activities emanate from the cost and value of obtaining raw materials, the building of systems, and the utilization and marketing of the products, be they in solid or aqueous extract forms. Economic returns are carefully valued from the production phase to its final utilization as an organic amendment for crops. The discussion revolves around the development of vermiculture as an art, a science, and an industry. It traces the early development of vermicomposting, which was used to manage organic wastes that were considered environmentally hazardous when disposed of improperly. It also presents the vermicomposting process, including its basic requirements, technology involved, and product characteristics, both in solid form and as a liquid extract. Research reports from different sources on the performance of the products are also provided. The discussion attempts to elucidate the mechanisms involved in plant growth and yield promotion and the suppression of pests and diseases. Certain limitations and challenges that the technology faces are presented as well.

Dried smoked skipjack or better known as Katsuo-bushi is a popular type of smoked fish in Japan. It has a distinctive flavor and widely used in traditional Japanese cuisine. The weakness of commercial Katsuo-bushi nowadays is the high content of Polycyclic Aromatic Hydrocarbon (PAH) (may exceed 10 ppb).  Recent study examined the low PAH Katsuo-bushi product made with liquid smoke. However, the sensory acceptance of this product has not been determined yet.  The purpose of this study was to determine the effect of liquid smoke concentration (1%, 2% and 3%) and soaking time (10, 20 and 30 min) on the sensory quality of Katsuo-bushi. Duo-trio method was used for sensory evaluation. Additional chemical analysis such as moisture content and pH were performed. Significant differences were found among liquid smoke Katsuo-bushi product compare to traditional Katsuo-bushi (P<0.1). Also, it is suggested that the longer the soaking time, the higher the moisture content and pH value. Keyword: Katsuo-bushi, liquid smoke, Duo trio method.   Ikan kayu atau lebih dikenal dengan Katsuo-bushi adalah sejenis ikan asap yang telah lama dikenal dan memiliki flavor yang khas yang biasanya digunakan pada masakan tradisional di Jepang.  Kelemahan ikan kayu yang ada di dunia dewasa ini adalah tingginya kandungan Polycyclic Aromatic Hydrocarbon (PAH) yang melebihi 10 ppb. Penelitian terkini (Berhimpon, dkk 2016) meneliti ikan kayu asap cair yang rendah PAH, tetapi belum diteliti tingkat kesukaan secara organoleptik. Penelitian ini adalah untuk mendapatkan ikan kayu asap cair yang rendah PAH tetapi disukai oleh konsumen. Tujuan penelitian ini ialah untuk mengetahui pengaruh konsentrasi asap cair dan lama perendaman terhadap mutu organoleptik ikan kayu asap cair yang dibuat dengan berbagai konsentrasi dan lama perendaman, dan dibandingkan dengan ikan kayu konvensional. Parameter pengamatan ialah analisa organoleptik dengan metode duo trio (Berhimpon, dkk. 2005), analisa kadar air dan pH (AOAC, 2005). Hasil penelitian ini menunjukkan bahwa ikan kayu yang direndam dalam asap cair dengan konsentrasi 2% dan 3% masing-masing selama 30 dan 10 menit berbeda sangat nyata (P<0,1) dengan ikan kayu konvensional. Sedangkan perlakuan yang lain sama dengan ikan kayu konvensional. Untuk analisa kadar air dan pH menunjukkan bahwa lama perendaman memberikan pengaruh yang nyata terhadap nilai kadar air dan pH dari ikan kayu asap cair, dimana semakin lama waktu perendaman dalam larutan asap cair maka semakin tinggi kadar air dan pH dari ikan kayu tersebut. Kata Kunci: Ikan kayu (Katsuo-bushi), asap cair, metode duo trio.

K Fertilization

Agriculture is the backbone of the Indian economy, in spite of concerned efforts towards industrialization in the last three decades. Therefore, the soil quality and fertility are the major factors in crop production. Declining soil fertility is one of the primary factors that directly affect crop productivity, and fertilizer-use is a key factor in order to keep soil fertility and productivity. A major factor in declining soil fertility is potassium (K) depletion, especially on smallholder farms where fertilization decisions are not based on regular soil testing. Most of the smallholder soybean producers do not have access and investment capacity to soil testing services. Therefore, there is a need to create K fertilizer recommendations based on empirically verified knowledge at India-specific scale. Such large-scale studies, in local filed conditions, are currently lacking. In order to bridge this gap, and generate proven set of directly applicable recommendations, a large-scale plot trial was launched; the Potash for Life (PFL) project. The study evaluated the K response in soybean when fertilizing with potash on K depleted soils in local variable field conditions. The aim was to (1) evaluate the effect and response consistency of K application on soybean yield, (2) to demonstrate to farmers the increased yield and profitability from K-inclusive fertilization regimes for this crop and give recommendations for transient yield increase, and (3) to raise the awareness among smallholder farmers about the importance of K fertilization. A comprehensive experiment was carried out in Madhya Pradesh (M.P.) and Maharashtra. The methodology was straight-forward; two identical plots side by side, with the only difference that one of them was fertilized with additional potash. The results showed a significant yield increase response from the potash application; the average yield increase was 244 kg ha-1 or 26 % in M.P., and 105 kg ha-1 or 36 % in Maharashtra. This entailed an average additional net profit of ₹ 6,681 INR ha-1 and ₹ 2,544 INR ha-1, in M.P. and Maharashtra respectively. It was concluded that the soil status of plant available K is significantly lower than the plant demand for soybean production in the two states, Consequently, K fertilization is necessary in order to improve agricultural practices and optimizing yields. Ultimately, following recommendations given in this study would allow farmers to generate additional profit, which could further allow them to invest in fine-tuning fertilizer practices through the means of soil testing.

Moringa Leaf Extract

Growth-promoting properties of moringa (Moringa oleifera) leaves were investigated for potential use in crop production by comparing the efficacy of bimonthly foliar and root applications of a moringa leaf extract [MLE (3.3% w/v)] with the cytokinins 6-benzyladenine (6-BA) and trans-zeatin (t-Z), each at 25 mg·L−1, to increase plant growth, flowering, yield, fruit size, and fruit quality of ‘Super Sweet 100’ cherry tomato (Solanum lycopersicum). Foliar-applied t-Z and root-applied MLE increased canopy biomass (P ≤ 0.01) and root- and foliar-applied MLE increased lateral vegetative shoot number (P ≤ 0.001) and plant height (P ≤ 0.001) relative to untreated control plants. Only foliar-applied MLE increased floral shoot number compared with untreated control plants (P ≤ 0.001). Plants in all treatments, except root-applied 6-BA, produced more flowers than untreated control plants (P ≤ 0.001). Plants receiving root-applied t-Z produced the greatest number of flowers followed by plants receiving root-applied MLE. Cherry tomato plants treated with root-applied t-Z or MLE produced the greatest number of fruit per plant and significantly more than untreated control plants (P ≤ 0.001). Foliar-applied 6-BA and MLE and root-applied t-Z and MLE increased yield as grams of fruit per plant compared with the untreated control (P ≤ 0.01). Foliar- and root-applied MLE increased fruit concentrations of soluble sugars (P ≤ 0.001), protein (P ≤ 0.001), antioxidants (P ≤ 0.001), and lycopene (P ≤ 0.001) compared with fruit from untreated control plants. Foliar- and/or root-applied MLE resulted in the greatest leaf concentrations of protein (P ≤ 0.01), proline (P ≤ 0.01), arginine (P ≤ 0.01), and total antioxidants (P ≤ 0.05), which were all significantly greater than the concentrations in leaves from untreated control plants. The results of this single experiment provide evidence suggesting that MLE warrants further research as an inexpensive growth promoter for enhancing tomato plant biomass, yield, and fruit quality, especially in organic crop production, which prohibits the use of many commercial synthetic plant growth regulators.

Bacteria play a vital role in the quality of soil, health, and the production of plants. This has led to several studies in understanding the diversity and structure in the plant rhizosphere. Over the years, there have been overwhelming advances in molecular biology which have led to the development of omics techniques which utilize RNA, DNA, or proteins as biomolecules; these have been gainfully used in plant–microbe interactions. The bacterial community found in the rhizosphere is known for its colonization around the roots due to availability of nutrients, and composition, and it affects the plant growth directly or indirectly. Metabolic fingerprinting enables a snapshot of the metabolic composition at a given time. We review metabolites with ample information on their benefit to plants and which are found in rhizobacteria such as Pseudomonas spp. and Bacillus spp. Exploring plant-growth-promoting rhizobacteria using omics techniques can be a true success story for agricultural sustainability.
