Experiments were conducted to study the effect of inorganic, organic and combined inorganic + organic fertilizer and natural shade under Gliricidia on the growth and dry matter (DM) yield of the medicinal plant Solanum virginianum Schrad. The yield of total dry matter and of different plant parts were also studied in plants harvested at 70, 90 and 110 days after establishment. Application of co...

Winter rye is an important crop of the Non-Chernozem belt Russia, productivity which depends on use fertilizers. The paper presents data agronomic and economic efficiency cultivating Falenskaya 4 winter under conditions long-term mineral studies were carried out in 2019-2021 Perm Region sod-podzolic heavy loamy soil a stationary experiment based reduced factorial design (6x6x6) with wide range ...

A field experiment was conducted to assess the optimum inter- and intra-row spacing on growth, yield and yield component of Roselle (Hibiscus sabdariffa L.) in 2014/15 cropping season at Wondo Genet Agricultural Research Center experimental site (at Wondo Genet station). Two inter-row spacing (60 and 90 cm) and three intra-row spacing (30, 60 and 90 cm) were evaluated using two varieties, WG-Hi...

ABSTRACT- The influence of foliar application of urea, humic acid (HA), Zinc (Zn), and Boron (B) on potato yield (CV. Cror) was studied in a field experiment during 2010-2012 at the research farm of Nuclear Institute for Food and Agriculture (NIFA). Treatments consisted of i) Control, ii) Nitrogen-Phosphorous-potassium (NPK) (250,150,250 kg ha-1) , iii) NPK (125,75,125 kg ha-1) with 0.03% HA, i...

Few systematic studies have been carried out on integrated N balance in extremely arid oasis agricultural areas. A two-year field experiment was conducted to evaluate the N input and output balances under long-term fertilization conditions. Five treatments were chosen, namely CK (no fertilizer), NPK, NPKS (10% straw return N and 90% chemical N), NPKM (one third urea-N, two thirds sheep manure) ...

Nitrogen is essential for both vegetative and generative stages of plant growth. Nitrogen efficiency is related to plant growth, production cost, and fertilizer residue. Azolla has the ability to increase nitrogen fixation from the atmosphere. Thus, Azolla cultivation in paddy field is one strategy for improving nitrogen fertilizer efficiency and increasing plant vegetative and generative growt...

Regaining the agricultural potential of sodic soils in the Indo-Gangetic plains necessitates the development of suitable salt tolerant rice varieties to provide an entry for other affordable agronomic and soil manipulation measures. Thus selection of high yielding rice varieties across a range of sodic soils is central. Evaluation of breeding lines through on-station and on-farm farmers' partic...

Mineral nutrition improvement contributed signifcantly to spring triticale grain yield. On average, during the two years of research, use 30–210 kg/ha active ingredient nitrogen fertilizers increased it 6.50–8.36 t/ha or by 14–46 % compared unfertilized plots (5.71 t/ha). The stability index yield formation was high – 0.92–0.95. Weather conditions in research were different. precipitation level...
