Abstract: The objective of this work was to evaluate alternative sources of potassium for improving soil fertility and coffee productivity and beverage quality. The experiment was conducted in a coffee (Coffea arabica) crop, planted in an Oxisol area, in the municipality of Patrocínio, in the state of Minas Gerais, Brazil. The treatments consisted of the K sources TK47 and Super Greensand (SG) - both based on glauconite silicate mineral -, at the following doses: 0 kg ha-1 K2O (control); 42, 84, 168, and 336 kg ha-1 K2O from TK47; 618 kg ha-1 K2O from KCl; and 168 kg ha-1 K2O from SG. A randomized complete block design was used, with four replicates in each treatment. The experimental units consisted of three rows with ten plants each, using the eight central plants as the useful plot. Potassium fertilization with TK47 increased soil fertility, correcting soil acidity and elevating K+, P, and Ca2+ contents, effective cation exchange capacity, and Zn2+ and Fe2+ levels in the soil. Fertilization with 336 kg ha-1 K2O from TK47, in a single dose, provides grain yield and polyphenol oxidase activity similar to those of fertilization with 618 kg ha-1 K2O from KCl, in a split-dose, but a better sensory analysis of the resultant beverage.

Excess use of agrochemicals for intensive cultivation affects crop quality and destroys agro-ecosystems, and eventually creates health hazards. The study aims to investigate the effect of Gliricidia sepium (GS) tree leaf as suitable green manures for supplementing nutrient supply along with nitrogen (N) fertilizer to produce quality tomato and soil fertility improvement. A field experiment was conducted at the Bangabandhu Sheikh Mujibur Rahman Agricultural University, Bangladesh, from November 2016 to March 2017. The experiment was laid out in a randomized complete block design (two factors) with three replications. There were nine treatment combinations with three levels of GS tree leaves (5, 10 and 15 t ha−1) and three doses of N (0, 50 and 100% of the recommended dose of fertilizer). The highest tomato yield was recorded in GS15×N100 treatment combination, which was 41.68% higher compared to the control treatment. Decreasing C: N ratio in increasing dose of GS and N treated plot indicated the quality of tree leaves that ensures faster decomposition and high nutrient release pattern of this species. Increasing rate of soil pH and cation exchange capacity (CEC) in different treatments as compared to initial soil showed soil fertility improvement. Overall, the results indicated that quality tomato could be grown successfully by the application of G. sepium tree leaves along with an appropriate amount of N fertilizer. Ann. Bangladesh Agric.

<p>New wetlands field generally has low productivity, so a technology is needed for improve productivity. New Superior Variety (NSV) is a technology that is considered easy to be adopted by farmers, so knowing a NSV that is able to adapt to the characteristics and conditions of new wetlands field is a must. The study of adaptive NSV on new wetlands field in Boven Digoel Regency is still limited so that the NSV recommendation for farmers is also still limited. The purpose of this study was to examine the growth and production of new superior varieties on the new wetlands fields in Boven Digoel Regency. The study was conducted on new wetlands in Asiki Village, Jair District during April-August 2019. Randomized Complete Block Design was employed with 3 replications using Inpari 36, Inpari 37, Inpago Rindang 1, Inpago Rindang 2 dan Inpara 8. The results showed different varieties perform different agronomy characters observed (plant height, number of tillers, panicle length, number of grains per panicle, filled grain, per panicle, empty grain per panicle and 1000 grain weight). Inpari 37 produced 5.3 ton/ha Dried Unhulled Rice, the highest production compared to other varieties, so that it could potentially be developed in Boven Digoel’s new wetlands field. Productivity may still be increased by improving soil fertility conditions.</p>

ABSTRACT The usual application of high 4-14-8 NPK fertilizer rates in the potato planting furrows, independently of the soil fertility or nutritional cultivar requirements, has become a paradigm in Brazil. However, the 4-14-8 NPK formula does not always meet the crop needs, and can unbalance the availability of nutrients in the soil. The objective of this study was to evaluate the tuber yield and economic results of ‘Atlantic’ potato as affected by rates of 4-14-8 and 6-30-6 NPK formulas applied in the planting furrows. The rates of both NPK formulas were calculated to reach P2O5 rates of 210, 420, and 630 kg ha-1. At each P2O5 rate, the 6-30-6 formula resulted in less 30% N and 65% K2O in the planting furrow compared to 4-14-8 formula. A randomized complete block design in a factorial scheme (2×3)+1, including an unfertilized furrow control, with three replications was used. Only the use of 6-30-6 formula increased the total tuber yield of ‘Atlantic’ potato. The marketable tuber yield reached higher levels (29.8 t ha-1) with higher P2O5 rate (440 kg ha-1) using the 6-30-6 than 4-14-8 formula. The fertilizer rates and formulas NPK did not affect specific gravity of marketable tubers. Therefore, the use of a fertilizer more concentrated in P2O5 that favors smaller contributions of N and K (as the 6-30-6 formula studied in this work) provides lower costs, and greater operational efficiency and profits in relation to the 4-14-8 formula traditionally used for the potato crop.

Abstract Indonesia has many types of carbohydrate sources. Tacca (Tacca leontopetaloides) has potential as a source of the functional food industry, especially maltotriose and maltotetraose production. Tacca grows well in an open or a shaded area on sandy soil-mineral, soil pH is slightly alkaline, with very low to low Cation Exchange Capacity. Malapari (Pongamia pinnata) is a biofuel-producing plant with a natural distribution on coastal land. Planting combination between malapari as an energy-producing plant and tacca as a food source has never existed. So, it needs to be incentives in developing agroforestry that can provide intermediate results for farmers. The requirement of good quality tacca seedlings is a crucial factor in supporting food security. This study aimed to determine the effect of the types of tacca seeds used on the initial growth of tacca. The study used a randomized complete block design consisting of 3 (three) treatments: a) large tubers, b) small tubers, and c) the origin of seeds. The results showed that plants from large tubers produced the highest number of shoots, height, and diameter (5.83; 27.77 cm and 0.43 cm). Five years old malapari reaches a diameter of 6.95 cm, a height of 3.89 m, and a crown width of 2.43 m.

Alley cropping or hedgerow intercropping is one of the many sub-systems of agroforestry technology. A 5 x 3 factorial experiment in a Randomized Complete Block Design (RCBD) with three replications was used to determine the effect of four alley woody species and three plantain cultivars on the yield of 60-day cowpea grain in the 2017 and 2018 farming seasons. The Alley species, plantain cultivars and Alley species x plantain cultivars treatment interactions showed no significant effects (p<0.05) on cowpea grain yield. Students t-test on the two farming seasons showed significant increase in yield of cowpea grain in 2018 than in 2017. Alley cropping technology could increase 60-day cowpea grain yield due to improved soil fertility in the system.

Forage Management

Increased production in smallholder beef systems requires improved forage management. Our objective was to evaluate the effects of composted cattle manure and mineral nitrogen (urea) application on soil fertility and partial nutrient balances in plots established toBrachiariacv. Mulato II in south-central coastal Vietnam from 2010 to 2013. A randomized complete block design was implemented on six farms (blocks), with five rates of composted cattle manure (0, 4, 8, 12, and 24 Mg DM/ha per yr) and three urea rates (0, 60, and 120 kg N/ha per yr) in a factorial design. Soil was analyzed before and after the experiment. Compost increased soil pH, organic matter, Ca, Mg, and Mn. The effect of compost and urea applications on postexperiment soil fertility depended on preexperiment soil fertility for K, P, S, Mg, Zn, Mn, Cu, and organic matter, suggesting that the ability to maintain soil fertility depends on the interaction between soil organic and inorganic amendments and existing soil fertility. Highest farm yields were also achieved on farms with higher preexperiment soil fertility levels. Negative partial nutrient balances for N, P, and K suggest that yields will not be sustainable over time even for the highest fertilization inputs used in this experiment.

A study was carried out to assess the effect of integrated Farmyard Manure (FYM) and inorganic NP fertilizers use on yield and soil properties in Bako-Tibe district of Oromia, western Ethiopia.  Five treatments  (i.e., 110 kg N ha-1 + 46 kg P2O5 ha-1 (T1), 12 ton FYM ha-1 (T2) , 55 kg N ha-1 + 23 kg P2O5 ha-1 + 6 ton FYM ha-1(T3),  27.5kg N ha-1  + 11.5 kg P2O5 ha-1 + 6 ton FYM ha-1(T4) and the control (T5)) were used in a Randomized Complete Block Design (RCBD) with five replications using  five farmers’ fields. Yield and yield related parameters were analyzed using SAS statistical software version 9.0. Economic analysis was performed to compare treatments advantages.  The treatment with half the recommended NP (55 kg N ha-1 + 23 kg P2O5 ha-1 + 6 ton FYM ha-1) showed superior plant growth performance as compared to other treatments. Pure use of inorganic NP resulted in high Na, K, Ca and P composition of grain while pure FYM use resulted in high content of Mg and Ca composition. The level of P in grain decreased with the increasing of FYM.  Soil fertility parameters considered showed no significance difference (P: 0.05) among the treatments. The mean difference values indicated that use of pure inorganic fertilizer increased soil PH, exchangeable Na, and available S. Use of pure farmyard manure resulted in an increase in the soil exchangeable Na, K, Mg, total Nitrogen, and available K and S. The use of half of the recommended inorganic fertilizer and FYM can enhance soil fertility in addition to yield improvement.

Organic fertilizer (OF) has positive effects on soil, especially soil fertility and productivity. Two experiments were conducted at the farmer’s field of Mymensingh and Jamalpur to observe the effect of organic fertilizer on cabbage production during rabi season 2018. There were seven fertilizer treatments viz: T1: RCF (N150 P40 K100 S16 Kg ha-1), T2: 85% RCF, T3: 70% RCF, T4: 85% RCF + 3 t ha-1 OF, T5: 85% RCF + 1 t ha-1 OF, T6: 70% RCF + 3 t ha-1 OF and T7: 70% RCF + 1 t ha-1 OF. The experiments were laid out in a RCBD (Randomized Complete Block Design) with three replications. The average fresh yield at Mymensingh ranged from 34.5 to 60.0 t ha-1 with the highest yield of 60.0 t ha-1 from treatment T4 (85% RCF + 3 t ha-1 OF). At Jamalpur, the average yield ranged from 31.5 to 56.3 t ha-1 and the highest yield of 56.3 t ha-1 was recorded from treatment T4 (85% RCF + 3 t ha-1 OF). The lowest yield was found from treatment T3 in both locations. The percent fresh yield increased over control (T1), was 42.85 and 40.04 in Mymensingh and Jamalpur, respectively. The highest gross margin is Tk. 534507, which was obtained from treatment T4 (85% RCF + 3 t ha-1 organic fertilizer). The highest MBCR 3.05 (average of two locations) was obtained from the same treatment T4 (85% RCF + 1 t ha-1 organic fertilizer). The result indicated that applying organic fertilizer and 85% recommended dose of chemical fertilizer is more profitable than applying chemical fertilizers only.

ABSTRACT The aim of this study was to evaluate the effect of thermally dried sewage sludge on soil fertility, growth and yield of sunflower. The experiment was conducted in a Nitosol area of the Institute of Agricultural Sciences of the Federal University of Minas Gerais, in Montes Claros-MG, Brazil. The treatments consisted of four doses of sewage sludge (0, 10, 20 or 30 t ha-1, dry weight basis), with six replicates in a randomized block design. The levels of nutrients in soil and plant, soil fertility indices, stem diameter, plant height, head diameter and grain yield were evaluated. Stem diameter, plant height, head diameter and grain yield increased with increasing doses of sewage sludge. The application of the residue increased linearly the contents of soil organic matter and N in sunflower leaves. On the other hand, pH, the exchangeable bases, total and effective cation exchange capacity, base saturation, H+Al, Al, soil contents of P, K, Ca, Mg, S, Zn, Cu, Mn, Fe and B, and the leaf contents of P, K, Ca, Mg, S, Zn, Cu, Mn, Fe and B were not influenced by the application of sewage sludge doses of up to 30 t ha-1.
