This research was aimed at developing a composting process of organic waste using natural and modified zeolites by ascertaining how effective they were in retaining phosphorus (P) after 60 days. The experiments included compost (C) containing natural (N) and modified (M) zeolite (Z) treatments (applied at 10% and 15% on a weight basis of the total waste): CNZ10, CNZ15, CMZ10, CMZ15 and C (which is the control treatment with no zeolite addition). The second objective was to compare the barley shoot biomass and nutrient concentration of the various compost treatments mixed with soil and control treatment (just soil) after 45 days of planting in the greenhouse. In general, the benefits of co-addition of compost and zeolite on sandy soil were tested in a completely randomized experimental design. The results indicated that the treatments with the highest zeolite treatments (CNZ15 and CMZ15) proved most effective at retaining P by the end of the composting process (2.8mg and 2.9mg respectively) compared to the lower zeolite ratios and the control treatment; CNZ10 (2.0mg), CMZ10 (1.9mg) and C (0.7mg). The barley shoot biomass results indicated that the treatments that had a combination of soil (S) and modified zeolite (SCMZ10 and SCMZ15) had biomass of 7.67g and 7.24g respectively, followed by the natural zeolite and compost treatments (SCNZ10, SCNZ15 and SC) having 6.19g, 6.38g and 5.99g respectively and were significantly different from the control treatment (S) which had the lowest biomass of 0.48g. With respect to the plant nutrient concentration, N and P were significantly higher in the control treatment (S) compared to the other treatments while K concentration was significantly highest in the compost and some of the zeolite treatments (SC, SCNZ15 and SCMZ15) compared to other treatments. These results were in line with some previous findings where zeolite was used as a soil amendment in agriculture.

Abstract World capture fisheries are declining while demand for fish is increasing due to population increase and an upward trend in diet preference where fish is preferred over white meat. It is hoped that aquaculture will help meet this deficit. In Kenya, coastal aquaculture remains under-developed even though over 3900 hectares of land have been designated as suitable for aquaculture. This case study is based on a study where Indian shrimp (Penaeus indicus) were cultured for 106 days, in hapas, inside fertilized ponds at Majaoni in Mtwapa creek, Mombasa district, Kenya. The manures used for pond fertilization were chicken, urea and cow dung. No manure was added in the control treatment. Physical, chemical and biological water parameters were taken weekly, fortnightly and monthly, respectively. Growth performance of the shrimp in terms of weight (g) and length (mm) was monitored fortnightly. The mean growth rates ranged between 1.13 and 2.34% day-1 in the control and chicken manure treated ponds, respectively. The highest net yield (NFY Kg ha-1) and annual production (AP Kg ha-1 yr-1) achieved was 18.87 Kg ha-1 and 64 Kg ha-1 yr-1, respectively, in the cow dung-treated ponds. The data collected from this study formed part of the author's MSc thesis in Aquaculture at the University of Nairobi. A major part of the study was funded by Alcoa Foundation's Conservation and Sustainability Fellowship Program which supported the author as a Practitioner Fellow in 2008. Additional support was provided through the Western Indian Ocean Marine Science Association (WIOMSA) small grant programme.

Bamboo shoots being low in fat, high in dietary fiber and rich in mineral contents have been consumed traditionally by the people world over. Besides nutrients it also contains some anti-nutrients e.g. cyanogens. Due to seasonal availability of bamboo shoots, processing for reducing anti-nutrients in raw shoots while keeping nutrients intact and enhancement of shelf life of the value added products assume great significance for its utilization. This paper focuses on post harvest processing and value addition of bamboo shoots for its utilization as food products. Juvenile bamboo shoots of Bambusa bambos, B. tulda, Dendrocalamus asper and D. strictus were collected and processed, by boiling in brine solution, to remove the anti-nutrients (cyanogen). A simple, efficient and cost effective processing method for bamboo shoots was developed. This method significantly reduces the amount of cyanogens and retains considerable amount of nutrients and thus may be utilized for processing of bamboo shoots. Different value added edible products viz. chunks or bari (by adding pulses), pickle, sauce and papad (by adding potato) were prepared. All products were good in taste and texture. Nutritional analysis was done to determine the shelf life of the products. The nutrient content of processed products (chunks, sauce, pickle and papad) showed a gradual decrease and need to be consumed within 6 months from the date of making. However, in case of papad the carbohydrate content did not decrease much but the taste was not acceptable after 8 months. Whereas, in case of pickles, even nutrient content decreased but the product was acceptable even after two years after preparation as it was good in taste and texture. Thus, processing and value addition practices can be considered as key to the future of sustainable management of bamboo resources because they not only provide quality edible products but also enable harvesters/collectors to get better income opportunities.

Abstract: The present study entitled “Development of protein rich flavoured bar” was conducted with the objective to develop protein rich flavoured bar using different ingredients, to assess the sensory accessibility, determine the nutritional composition and cost of developed protein bar. Protein rich flavoured bar were prepared by using three treatments i.e. T1 (dates 50g, oats 10g, flaxseeds 5g, sesame seeds 5g, pumpkin seeds 5g, peanut powder 10g, honey 5g, cocoa powder 10g), T2 (dates 45g, oats 8g, flaxseeds 5g, sesame seeds 5g, pumpkin seeds 5g, peanut powder 10g, honey 12g, guava flavour 10g) and T3 (dates 40g, oats 13g, flaxseeds 5g, sesame seeds 5g, pumpkin seeds 5g, peanut powder 10g, honey 12g, orange flavour 10g). Organoleptic evaluation of the prepared product in relation to sensory attributes was carried out using the nine point hedonic scale score card by Srilaksmi (2015). The nutrient content of the value added food products were calculated with the help of food composition table given by Gopalan et al., (2011). The cost of individual raw ingredients used in the preparation of the food product as the prevailing market price. All treatments were replicated four times and the data obtained during investigation were statistically analyzed by using analysis of variance (ANOVA) and critical difference (C.D.) techniques. On the basis of sensory acceptability it was found that T1 was scored highest in terms of colour and appearance, body and texture, flavour and taste and overall acceptability. As well as T1 shows significantly high in the nutritive value among all treatments regarding energy, protein, carbohydrates, fat, fibre, calcium and iron. The cost of the protein rich flavoured bar per 100g of dry ingredients at the prevailing cost of the raw materials was highest in T1 (Rs. 29.33) followed by T2 (Rs. 20.69) and T3 (Rs. 20.34). Dates are very good source of fibre, carbohydrate, protein and act as natural sweetener with no fat. As the bar is rich in protein, iron and other macronutrients, so it is majorly recommended for Protein-energy malnutrition (PEM), athletes and anemic patient. Daily 100g of dates intake helps to get all essential nutrients. Strictly restricted for Type-1 diabetic patients. Keywords: Protein, Nutrient content, organoleptic evaluation, nutrition bar, cost.

The experiment was carried out   using pots in a greenhouse with a randomized block  experimental design  and  four replicates. Soil solution was collected by solution extractors installed in pots. Ten collections were performed over 137 days after fertilizer application, which included two crops in a row of black oat (cultivation I and cultivation II). In both soils, yield of dry matter in cultivation I was higher in OF-P, and  it was similar in  (SM-P), (MF-P) and (OF-P) in cultivation II. Higher yield was obtained in LVd in relation to TQ.  Phosphorus content in soil solution ranged over time just in OF-P in LVd, whereas  variation was observed in all treatments in TQ. In both soils, higher content was observed as of cultivation II.   Also, variation over time was observed for pH and electrical conductivity (EC) values in both soils. Values of pH increased and values of EC decreased in cultivation II as compared with those in cultivation I in all treatments. Keywords: liquid and solid fertilizer, residue, manure.

Abstract Quinoa (Chenopodium quinoa Will.) is an annual herbaceous Andean plant. In recent years there is a growing interest on it due to its high quality as food, its wide adaptation to agroecological conditions and resistance to different abiotic stresses. In this work, we evaluate the growth pattern of quinoa plants cv. ‘Titicaca’, subjected to different levels of salinity, focusing on leaf production and nutrient content. In this sense, the results have shown that a high concentration of salinity negatively affects the growth of quinoa plants. In fact, plants grown with 200 mM NaCl reduced the photosynthetic rate and levels of chlorophylls and carotenoids in comparison with the rest of the treatments. Likewise, it has been proven how the progressive increase in salinity has negative effects on transpiration, stomatal conductance and photosynthetic rate, with significant subsequent reductions in shoot biomass, leaf area and nutrient adquisition, but without a decline in leaf dry weight (DW) production. However, the treatment of 200 mM NaCl demonstrated the best results regarding the water-use efficiency, as well as the number of saline glands. According to our results, the quinoa plant cv. ‘Titicaca’ seems to be tolerant to moderate concentrations of salinity (50–100 mM NaCl). This study could serve as a reference on this little known and cultivated species in the Mediterranean region, since it could become an alternative crop in areas with moderate salinity problems.

A pot experiment was conducted at the experimental net house of the Department of Soil Science, Sylhet Agricultural University, Sylhet, Bangladesh to observe the effect of fertilizers on yield and nutrient uptake of local aromatic rice varieties during the Aman season of 2015. The experiment was laid out in a Randomized Complete Block Design with three replications. Five local aromatic rice varieties (Kalizira: V1, Muktasail: V2, Nagrasail: V3, Maloti: V4 and Chinigura: V5) and four packages of fertilizers (F1:  Recommended package i.e. 45-10-20-10-0.5 kg ha-1 of N-P-K-S-Zn, F2: 2/3rd of recommended package, F3: 1/3rd of recommended package, and F4: Control) were used. Urea, TSP, MoP, gypsum and ZnSO4 were used as N, P, K, S and Zn source, respectively. According to the treatment, all fertilizers were applied as basal during final pot preparation while urea was applied in two equal splits (one half as basal and another half at 40 DAT). Nutrient content and uptake of the aromatic rice varieties were significantly affected by the application of different fertilizer packages (with few exceptions). Mostly Kalizira (1.10-0.44-2.31-0.67-13.75 g pot-1 of N-P-K-S-Zn) and/or Nagrasail (1.15-0.46-2.70-0.62-11.74 g pot-1 of N-P-K-S-Zn) varieties showed the highest nutrient uptake in grain and straw with recommended package of fertilizers. While in maximum cases Chinigura (0.41-0.16-0.76-0.197-3.17 g pot-1 of N-P-K-S-Zn) was observed to have the lowest with control treatment. In case of post harvest soil nutrient analyses, Kalizira and/or Chinigura variety associated with recommended package of fertilizers showed the highest nutrient status.

Fiber and cocopeat are waste products from coconut husks that can be turned into value added products. Fiber and cocopeat from old coconut husks are well known in coconut industry in the world. This paper described fibre strength from young coconut husks, nutrient content and water-holding ability of young coconut cocopeat compared to old coconut cocopeat. The strength of fiber was determined by using Instron Universal Testing Machine. The results showed that mean load at break for young coconut fiber was 13.76 N while mean load at break for old coconut fiber was 14.93 N. Maximum tensile stress for young coconut fiber was 1.55 MPa and 1.76 MPa for old coconut fiber. The nutrient contents were determined for young cocopeat and old cocopeat resulted as phosphorus (372.79 ppm, 339 ppm), potassium (6829.68 ppm, 10040.46 ppm), calcium (508.74 ppm, 578.40 ppm), magnesium (468.67 ppm, 715.60 ppm) and sodium (1579.70 ppm, 3917.60 ppm). The pH value was 6.55 and 5.39 respectively. The ash contents were 2.62% for young cocopeat while 4.06% for old cocopeat. For water holding ability test, moisture content of each sample from young coconut cocopeat and old coconut cocopeat was determined by using soil moisture meter. After seven days with water added 500 ml two times/day, results showed that water holding ability for peat moss was the best while young cocopeat was better than the old cocopeat. All the results showed that fiber and cocopeat from young coconut husk have high potential for sustainable production in the coconut industry.

The experiment was conducted at Regional Agricultural Research Station (RARS), Jamalpur, Bangladesh during the period of 2019-2020 and 2020-2021 to investigate the effect of vermiwash on growth, yield and quality of brinjal and to find out suitable foliar dose of vermiwash for optimizing the yield of brinjal. There were five treatments comprising T1= Chemical fertilizer (CF) + foliar spray of distilled water (control), T2 = CF + foliar spray of 10% vermiwash, T3 = CF + foliar spray of 20% vermiwash, T4 = CF + foliar spray of 30% vermiwash and T5= CF + foliar spray of 40% vermiwash. Results revealed that, vermiwash treated brinjal plants showed better growth and yield parameters than the control plants. The highest average brinjal fruit yield (29.99 t ha-1) was found in T3 treatment i.e., foliar spray of 20% concentration of vermiwash and the lowest (26.35 t ha-1) came from control. On the other hand, nutritional quality (moisture content, TSS, β carotene and nutrient content) were seen to be higher in vermiwash treated treatment compared to control treatment. The study suggests that, 20% concentration of vermiwash could be used as effective foliar spray for eco-friendly and higher yield of brinjal.
