Abstract Rice is the primary staple food for more than 50% of world’s population. Narrowing gap between maximum potential crop yield and actual critical improving current yield, resource use efficiency, global security. Here, we examined fertilizer efficiency (FUE), radiation (RUE), temperature production (TPE) four management treatments (super high [SH], [HH], farmer level [FP], basic [CK]). S...

An experiment was conducted in the experimental field of Rajshahi University Campus, Bangladesh during the rabi season of 2004-2005 to study the growth attributes of four varieties of barley (BARI Barley-1, BARI Barley-2, BHL-3, BL-1) in relation to different soil moisture regimes and NPK fertilizers. Three levels of irrigation (I0, I1, I2) and four levels of NPK fertilizers (F0, F1, F2, F3) we...

Coffee is one of the most socioeconomically important crops worldwide. Currently, environmental variations due to climate change are affecting coffee development and growth. Therefore, it evaluate areas that offer a different environment during seedling stage since fundamental for successful cultivation. Four municipalities located at altitudes in Department Nariño were selected: La Florida (18...

Cucumber seedling growth under constant and fluctuating photosynthetic photon flux density (PPFD) light (CPL FPL, respectively) was examined to discuss whether plants can acclimate CPL versus FPL. The FPL created in a chamber by artificially reproducing fluctuations ground-level sunlight PPFD using phosphor-converted white LEDs. daily mean at the canopy surface photoperiod were same for grown t...

in order reaching to occurate water regime under minimum tillage system and its effect on the physiological indices of 3 rice cultivars an experiment  was conducted as a split-plot design based on  randomized complete block with three replication in the year of 2006-2007 at research field of shavour station. treatment contains three water regimes with one day or check, two (i2) and three days (...

growth traits, yield and fruit quality in ‘synda’ tomato were compared with those in tomatoes grafted onto either ‘king kong’ rootstock or onto their own rootstocks, (trained as single or double stem), and at two fruit thinning levels, of: no thinning or thinned to five fruits per truss. the data related to crop growth rate (cgr), relative growth rate (rgr), net assimilation rate (nar), leaf ar...

in order to study the yield and growth indix of potato under water deficit, an experiment was conducted with line-source sprinkler irrigation in khorasan razavi agricultural and natural resource research center. water deficit levels were included, at 0.75m from line-source (control), at 3.75m from line source (very mild deficit), at 6.75m from line-source (mild deficit), at 9.75m from line-sour...

water and nutrient absorption by plants is one of the most conspicuous factors which seriously affect plant productivity. improving physical properties of soilless media and their water retaining capacity can improve plant's nutrient absorption, growth and subsequent yield. in this study, we tried to improve plant nutrient absorption through incorporation of hydrogel into growth media and ...
