Assessment of water quality of drains from irrigation district in a semiarid agricultural zone

Worldwide wastewater is used for agriculture, because of water scarcity. Also, there are increasingly fewer sources of good quality water because of widespread contamination (Ramirez-Fuentes et al., 2002; Rutkowski et al., 2007, Qadir et al., 2010).Agronomic water quality effects on soil, crops and management; major problem with the use of wastewater are salinity, soil permeability […]

Character association and path analysis of soybean (Glycine max L.) genotypes under water deficit stress

Knowledge of interrelationships between seed yield and its contributing components will improve the efficiency of breeding programs through the use of appropriate selection indices. The objective of this study was to evaluate of interrelationships among seed yield and related characters in four soybean genotypes. The genotypes were evaluated using a split-plots design based on randomized […]

Analysis of the relationship between root morphology and uptake of fertilizer nitrogen in rice (Oryza sativa L.)

Due to the roles of root in water and mineral uptake, it is one of the most important organs for plant growth. In order to analyze the morphological differences of the root in four Iranian cultivars of rice (Tabesh, Fajr, Tarom-e-Mahali and Neamat cultivars) and their relationship with nitrogen uptake, two experiments were conducted in […]

Effect of salicylic acid on alleviation of salt stress on growth and some physiological traits of wheat

To evaluate the effect of salt stress and salicylic acid application on growth and yield component traits of wheat, an experiment was conducted in factorial based on RCBD design with 3 replications in research farm (green house condition) of University of Tehran (Karaj-Iran) during 2010-11. Salt stress factor including three levels (control, salt stress with […]

Performance of short duration rice mutants and assessment of genetic diversity using RAPD and ISSR markers

Eleven short duration rice mutants along with their parent (Mandakini) and three standard checks (Jogesh, Nilagiri and Annapurna) were evaluated in the field. ORT 11, ORT 30 and ORT 35 out yielded significantly (>3250kg/ha) as compared to the parent (2830kg/ha) and also the best standard check variety Annapurna (2950q/ha). High yield performance of the aforesaid […]

Performance evaluation of a locally developed rice dehulling machine

The performance of a locally fabricated rice milling machine at Federal University of Technology, Minna was evaluated to determine the behavior of different paddy varieties at different conditions during milling. The varieties used were: FARO52, Nerica1 and FARO55 which represent long, medium and short grain respectively commonly grown by Nigerian farmers. Ten kilogram of each […]
