Considering the global tendency towards using valuable secondary metabolites of plant origin, there is a need to optimize cultivation herbal plants, e.g., meadow arnica (A. chamissonis Less.). The inflorescences this species (Arnicae anthodium) have similar chemical composition and pharmacological activity that in mountain (Arnica montana L.), can be cultivated more easily than arnica. Therefor...

Sweet sorghum is tolerant to high temperature and drought and can be considered as an alternative crop to sugar beet and maize in Iran. In this study, the effects of nitrogen and potassium fertilizers on growth parameters including stem height, stem diameter, stem fresh weight, total fresh weight; carbohydrate contents including total sugar, brix value, sucrose content and purify; and juice ext...

There is evidence that halothane inhibits nitric oxide synthase in vitro, but the effect of intravenous anaesthetic agents is less clear. This study was undertaken to compare the rate of exhaled nitric oxide production (VNO) in spontaneously breathing horses anaesthetized with halothane or an intravenous regimen. Seven adult horses were studied twice in random order. After premedication with ro...

The yield and quality parameters of potato tubers Gala variety were determined in the conditions Middle Urals 2020 2022 long-term stationary experiment after prolonged application NPK increasing rates (30-60-90-120-150 kg a.i.). by 60 a.i./ha more promoted raise 1.1-1.3 times 1.3-1.5 compared with control variant without fertilizers (21.4 14.4 t/ha years, respectively). lowest dry matter conten...

Several preemergent herbicides were compared for control of the warm season annuals Phyllanthus urinaria and P. tenellus. Approximately 55 seeds per species were applied to each 3.8-liter container filled with a pine bark:Canadian sphagnum peat:sand medium (3:1:1, by vol.; initial pH = 5.6). The six treatments (including untreated pots), with four replications per treatment and three pots per r...

Field experiment was conducted at International Crops Research Institute for the Semi-Arid Tropics, Hyderabad during early summer season in 2021 and 2022 to study “Effect of integrated use Nano Non–Nano fertilizers on growth yield sunflower under semi-arid conditions”. The carried out using randomized block design with 3 replications comprised 12 treatments. averages all indicators were compare...

The documentation process is very important for identifying yield constraint factors and yield gap. For this purpose, all managing practices were recorded by monitoring of paddy rice fields in Sari region, Iran from 2015 to 2016. Field identifications were undertaken in such a way that they included all the main production procedures with variations in management viewpoints. The results reveale...

Moso bamboo, well known for its high growth rate, is being subjected to increasing amounts of nitrogen deposition. However, how anthropogenic management practices regulate the effects of N deposition on Moso bamboo stoichiometry remains poorly understood. We observed the effects of two years of simulated N deposition (30, 60 and 90 kg N ha(-1)yr(-1)) on the foliar stoichiometry of Moso bamboo p...

INTRODUCTION Pigeonpea (Cajanus cajan L. Millsp.) is an important pulse crop in the semi-arid tropics and subtropical farming systems, providing high quality vegetable protein, animal feed and firewood (Mittal and Ujagir, 2005). The crop yields are generally hampered by many pests, which are problematic over years (Kumar and Nath, 2002). Major constraint in the production of pigeonpea is the da...
