Organic Compost

Composting is a technique used to obtain a nutrient-rich, plant-like organic compost. Considering that there are few studies that shows the efficiency of these composts in the cultivation of vegetables, the objective of this study was to evaluate, in the cultivation of lettuce, the quality of the final compost obtained from tree pruning, dairy sludge and coffee grounds—compost 1; grass, dairy sludge and coffee grounds—compost 2; grass, dairy sludge, coffee grounds and boiler ash—compost 3. Lettuce (Lactuca Sativa L.) were planted for the study with the three composts and a control object-without compost, and a portion with NPK fertilizer. The evaluated parameters were plant growth, head diameter, leaf number, dry mass and fresh mass. The results shows statistical similarities between the organic fertilizers and NPK fertilizer in the evaluated parameters and the control plot presented inferior results to the other plots, emphasizing the need for fertilization at each planting.

Npk Fertilization

A field experiment was conducted during summer season of 2007 at the Demonstration Farm of the Faculty of Agriculture, University of Khartoum, Shambat, Sudan, to investigate the effect of seed rate and NPK fertilization on yield and quality of Rhodes grass forage (Chloris gayana L. Kunth) cv. Finecut. The treatment consisted of three seed rates (SDR1, SDR2 and SDR3) namely 5, 10 and 15 kg/ha and three NPK fertilizer levels (F0, F1 and F2) namely 0, 120 and 240 kg/ha respectively. NPK fertilizer components were N17 P17 K17. The experiment was laid out in a Factorial CRBD with four replications. The results showed that seed rate significantly increased forage fresh and dry yield. NPK fertilization significantly increased forage fresh and dry yield. Neither seed rate nor NPK fertilization were significantly affected crude protein and fiber content of leaves and stems of Rhodes grass, but the increase in seed rate and fertilizer levels slightly increased crude protein and decreased fiber percentage. Seed rate ×NPK fertilization interaction showed significant effect on crude protein and crude fiber contents. The highest protein percentage obtained under SDR2 (10kg/ha) with highest NPK fertilization level F2 (240 kg/ha), and lowest value obtained under SDR1(5kg/ha) with NPK fertilization F1(120kg/ha) and SDR1(5kg/ha) under control of fertilizer treatment (F0). Regarding crude fiber, highest value obtained under SDR2(10 kg/ha) with NPK fertilization F1 (120kg/ha) and SDR3 (15 kg/ha) under control treatments of fertilization (F0).

Limited Application

Yield and quality of forage mainly depend on the floristic composition, ie the share of higher quality grasses and legumes, soil fertility, amount and distribution of precipitation and light. Natural meadows and pastures are the most important resource in the forage production in the hilly and mountainous area of Republic of Serbia. Despite the large areas, the forage production on natural grasslands is relatively low. Limited application of a small number of agrotechnical measures is the main reason for low and unstable yields and poor forage quality. Only by appropriate fertilization of meadows and pastures with mineral and organic fertilizers, their rational exploitation, it is possible to achieve an increase in hay yield by several times and improvement in forage quality, simultaneously.

Aim. To study the specifi cities of the effect of anhydrous ammonia on the indices of soil fertility, yield and quality of winter wheat grain compared to granular nitrogen fertilizers in order to elaborate intensive produc- tion technologies. Methods. The content of mineral nitrogen in the soil was determined according to DSTU 4729-2007, the content of movable phosphorus and potassium forms − by Chirikov’s method (DSTU 4115- 2002). The abundance of the main ecological and trophic groups was registered after sowing the soil suspen- sion on dense nutrient media. The concentration of total nitrogen, phosphorus, and potassium in plant samples was determined according to the measurement procedure 31-497058-019-2005. The quality indices of grain, i.e. protein and crude fi ber content as well as general glassiness were determined using Inframatic 8600 NIR analyzer, Perten Instruments AB (Sweden). Results. The specifi cities of the effect of anhydrous ammonia on the indices of soil fertility, the use of nutrients from fertilizers and soil, the yield and quality of winter wheat grain were demonstrated. Conclusions. The advantages of anhydrous ammonia application prior to sowing compared to the use of ammonia nitrate, traditional for Ukrainian agriculture after the growing season, were established.

Considerable Damage

The use of chemical pesticides in agriculture demands high investments; its in discriminated and inadequate application to obtain immediate crop response has caused considerable damage to the environment and human health, either due to a direct effect or indirect contamination of farmer fields and water sources by highly toxic products. On the other hand, as a result of soil fertility losses, farmers move to new areas for farming, causing a complex migration phenomena and devastation of natural forests. In an effort to find new alternatives for the management of crop pests compatible with the environment and agro-ecologically friendly, some technologies recently developed have been offered to small Andean potato farmers. Among these, the recycling of organic residues and the management of natural soil microorganisms which are important alternatives to reduce the importation and use of toxic agro-chemicals as well as to preserve and recuperate soil fertility and thus reach a sustainable potato production by Andean farmers. This will not only guarantee food security, but will also have favorable impact on the yield and quality of potato and other crops.Accepted for publication: December 28, 2011
