tion and nodulation, thus reducing N2 fixation capacity (Shibles, 1998). Application of N before planting or durNitrogen application during soybean [Glycine max (L.) Merrill] ing the early growth stages can suppress the N2 fixation reproductive stages has the potential to increase soybean productivity. The objective of this study was to determine the impact of N fertilizer process. Fertilizer N...

Four million hectares of wheat are planted after cotton and rice in Pakistan. Little research has been done on the aronomy of wheat following these crops on a cropping pattern basis. Both of these crops delay wheat planting, and it is estimated that 40–50 kg of wheat grain is lost for every day that planting is delayed past 20 November. Current recommendations for land preparation, fertilizer u...

Green manure (GM) is widely adopted for agricultural productivity and sustainability. The present study supplemented the GM effect with that of water retaining agent (WRA) to enhance sustainability tobacco planting purple soils in Sichuan Province, China. employed three legumes varieties (Trifolium repens, Vicia villosa Medicago sativa), while WRA used was polyacrylamide at different applicatio...

Algae are a diverse group of aquatic organisms and have potential to produce renewable biofuel via hydrothermal liquefaction (HTL). This study investigated the effects reaction environments on biocrude production from “Tetraselmis sp.” algae strain by HTL process using red mud (RM) based catalyst. The inert (N2), ethylene (C2H4), reducing (10% H2/90% N2), oxidizing O2/90% N2) were applied non-c...

The use of water resources should be restricted until a suitable irrigation and planting system is developed in the North China Plain. This study was aimed to study the effects of planting pattern and irrigation on the farmland microclimate, and indentify possible ways to improve the yield of winter wheat. The field experiments in a randomized complete block design with four replicates were con...

in order to study the canopy temperature effect on protein and soluble sugar, oil percentage and yield of soybean in different planting dates, an experiment was conducted as factorial based on randomized complete block design with three replications in karaj and moghan areas during 2012-13. the studied treatments were included cultivar (‘williams’ and ‘l17’) and planting date (5th of may, 5th o...

abstract sour cherry (prunus cerasus l.) is an important iranian-native fruit, considered highly perishable commodity which cannot be stored for any length of time. on this study, effect of three gas compositions (ambient, 5% o2+5% co2+90% n2 and 10% o2+15% co2+75% n2) and two storage temperatures (0 and 5 °c) on two sour cherry cultivars namely erdy jubileum and erdy botermo was studied in a c...
