The research was aimed at analyzing the performance of winter potato under different nitrogen rates experimental fields College Agriculture, Central Agricultural University, Imphal. variety Kufri Sindhuri cultivated during seasons 2017-18 and 2018-19 three rates- 120 kgha-1 (N1), 100 (N2) 80 (N3) using drip irrigation. results indicated that plants fertilized with recorded maximum germination p...

Branches of nine-year-old loblolly pine trees grown in a 2 x 2 factorial combination of fertilization and irrigation were exposed for 11 months to ambient, ambient + 175, or ambient + 350 micro mol mol(-1) CO(2). Rates of light-saturated net photosynthesis (A(max)), maximum stomatal conductance to water vapor (g(max)), and foliar nitrogen concentration (% dry mass) were assessed monthly from Ap...

BACKGROUND: Management of nutrients, especially nitrogen, in order to have economic production, maintain sustainable agriculture and provide food security, is considered to have an important priority. OBJECTIVES: Current study was conducted to evaluate effect of different level of nitrogen fertilizer and vermicompost on quantitative and qualitative traits of w...

Fertilized home lawns represent a potential source of NO,-N contamination to groundwater and surface waters. The waterborne losses of inorganic N from Kentucky bluegrass (Poa pratensis L.) turf subjected to three levels of N fertilization (0, 97, and 244 kg N ha"' yr~' as urea and methylene urea) and two irrigation regimes (scheduled by tensiometer and overwatering with 3.75 cm of water per wee...

this research was conducted to study the effects of water deficiency stress, nitrogen application rates, and plant population on water use efficiency and nitrogen of oily sunflower in 2007-2008 agriculture and research center of west-azerbaijan. the study was consisted split-split-plot experiments using randomized complete block design with 3 replications. the factor main was consisted irrigati...

in the water-limited areas, the great challenge of the agricultural sector is more production from less water that it can be achieved by increasing water productivity. a field study was conducted to compare various cultivars of wheat to water using line source sprinkler irrigation at gorgan research station in 2005-2006. the effect of variable water supply on yield and wue of six wheat cultivar...

in order to evaluate the effects of organic fertilizer complements application (aminol forte, fosnutren and kadostim) on grain yield, milling properties and nitrogen use efficiency of two rice (oryza sativa l.) cultivars, a field experiment in factorial layout and a randomized complete block design with 10 treatments and 3 replications was conducted at rice research institute of iran in 2009. t...

A field experiment was carried out during 2009-11 on a sandy loam soil of IARI, New Delhi on wheat with four levels of irrigation (rainfed, irrigations to replenish 30, 60 and 100% moisture deficit from field capacity) as main plot factors and four levels of nitrogen (0, 30, 60 and 120 kg N/ha) as subplot factors in a split plot design. The soil moisture storage in the profile showed inverse re...

Dry direct seeding cultivation technology of rice is an important aspect production and management. Six treatments were designed in this paper, that is, T1 (conventional irrigation), T2 irrigation + conditioner), T3 (30% water-saving T4 T5 (50% T6 conditioner). The results showed the three separate treatments, 30% was conducive to growth dry at tillering stage, jointing booting 50% more grain f...

to study the effects of below leaves excision and nitrogen application on stomatal characteristics of wheat flag leaf, grain protein, dry matter remobilization, grain yield and yield component, leaf area of winter wheat (t. aestivum cv. ghods) was artificially reduced under filed condition. the experimental design was a factorial on a rcb with 3 replications, a combination of three levels of de...
