Abstract

The paper presents the data on winter rye cultivation technology studies conducted during the period 1989-2001. The field trials carried out on a Haplic Luvisol were designed to estimate the effects of soil preparation, seed rate and nitrogen fertilization on winter rye grain yield and on the number and mass of weeds. With increasing the sowing rate of winter rye from 2.7 million seed ha-1 to 5.7 million seed ha-1 the weed dry mass decreased from 27.7 g m-2 to 19.8 g m-2 in the disk - cultivated ploughed soil and from 36.5 g m-2 to 23.6 g m-2 in the ploughed soil. Nitrogen fertilization had a greater effect on the yield than the seed rate. Having used nitrogen, winter rye yield was by 70.4 % higher in the ploughed soil and by 66.6 % higher in the disked soil compared with the yield of rye crops that did not receive any nitrogen. Lietuvos žemdirbystės instituto Vokės filialo bandymų lauke, kuriame vyravo priesmėlis ant karbonatinio fliuvioglacialinio žvyro paprastojo išplautžemio (Idp) Haplic Luvisols (LVh), 1989-2001 metais atlikti lauko bandymai, kur tirta įprastinio ir supaprastinto žemės dirbimo įtaka žieminiams rugiams. Dirva buvo suarta arba tik sulėkščiuota, žiemiai rugiai netręšti ir tręšti N45 ir N90 kg ha-1 norma, sėta 2,7, 4,2 ir 5,7 mln. daigių žieminių rugių 'Duoniai' sėklų į hektarą. Nustatyta, kad tik lėkščiuotoje dirvoje padidinus žieminių rugių sėklos normą nuo 2,7 iki 5,7 mln. ha-1, piktžolių masė sumažėjo nuo 27,7 g m-2 iki 19,8 g m-2. Kai dirva žieminiams rugiams buvo suarta, išsėjus tokią pačią žieminių rugių sėklos normą, piktžolių masė sumažėjo atitinkamai nuo 36,5 g m-2 iki 23,6 g m-2. Tręšiant azotu, nuosekliai padidėjo žieminių rugių grūdų derlius. Rugius patręšus azotu, artoje dirvoje derlius buvo 70,4 %, o lėkščiuotoje dirvoje - 66,6 % didesnis, palyginus su netręšto pasėlio derliumi.

Abstract

Field experiments were carried out at the Voke Branch of Lithuanian Institute of Agriculture. On sandy loam Haplic Luvisol. The objective was to produce as much as possible of green forage from the same field per year. Winter rye was grown as winter catch crop and was fertilized with farmyard manure at 40 t ha-1 and mineral N60P60K60 fertilizers. Rye for green forage was cut in the second half of May and after shallow soil tillage, mixtures of various annual legume crops with oats and pure faba beans, fodder lupine and maize were sown. At the end of July or beginning of August, having harvested green matter yield, the soil was disked, harrowed and oil radish was sown. It was found that under Lithuanian agroclimatic conditions when winter catch crops and are followed by post crops, it is possible to obtain three green matter yields of different crops per year, to produce 81,7-86,5 t ha-1 of green mass, 11,8-12,6 t ha-1 of dry matter, 11371 feed units, 1189 kg ha-1 digestible protein yield.

Abstract

The trials were carried out at the Voke Branch of the Lithuanian Institute of Agriculture during the period 2003-2007 and were designed to investigate the influence of organic (without fertilizers) and sustainable (the plants were fertilized only with bonemeal as a source of phosphorus and magnesia of potassium as a source of potassium) farming systems on crops and to explore their productivity, chemical properties of soil and balance of nutrients in the soil. The data of investigation show that productivity of plant rotations depends to the cultivated plants and the applied farming system. The highest yield was reviewed cultivating plants after green manure (lupines and white mustard) in two farming systems. Crop rotations had no effect to the soil acidity and increased total nitrogen and organic carbon content in the soil. Phosphorus amount in the soil increased in all farming systems, potassium only in sustainable farming system. The data about the number of micromycetes, organic and mineral nitrogen assimilating bacteria in the rizosphere soil of various grown plants are also presented. [ABSTRACT FROM AUTHOR]
