A field experiment was carried out during Rabi season 2019-20 at wheat and barley section research area of CCS Haryana Agricultural University, Hisar. The comprised three nitrogen doses (N1-60, N2-75 N3- 90 kg N/ha) as main plot treatments four seed rates (S1- 87.5, S2- 100, S3- 112.5 S4-125.0 kg/ha) sub treatments. With replications, laid in split design. Based on the investigation, it found t...

Nitrogen deficiency can seriously reduce yield, while over-fertilization can result problems such as excess nutrient runoff and groundwater pollution. Hence, efficient methods for assessing crop nitrogen status are needed to enable more optimal fertilizer management. The ability to quantify the different nitrogen application rates by crops using digital images taken from an unmanned aerial vehi...

Decreased N2 fixation in soybean (Glycine max) L. Merr. during water deficits has been associated with increases in ureides and free amino acids in plant tissues, indicating a potential feedback inhibition by these compounds in response to drought. We evaluated concentrations of ureides and amino acids in leaf and nodule tissue and the concurrent change in N2 fixation in response to exogenous u...

Physostigmine, at 0.1, 0.2 and 0.3 mg/kg, was tested for effect on the survival of mice exposed to 5% O2-95% N2. Some treated animals survived for one hour under the hypoxic atmosphere (2 out of 14 at 0.1 mg/kg and 8 out of 28 at 0.2 and 0.3 mg/kg), an event never observed in untreated controls. The physostigmine-treated animals that died before the hour showed a dose-related increase in surviv...

effects of different planting on phenology, grain yield and its components of two sunflower culitvars were investigated. in 1996, an experiment was conducted in the experimental field of azad islamic university of khorasgan, located in khatonabad village, isfahan. the experiment was arranged in a randomized complete block design with a split plot layaout and four replications. the main plots co...

In a replicated field plot experiment, the population density of Meloidogyne incognita was monitored biweekly through the overwintering period (December through April) between soybean crops. The population survived as second-stage juveniles whose numbers remained stable through the winter months and did not decline until February. The yields of plots planted with a M. incognita susceptible cult...

A study was conducted in the Shandong province in North China to investigate the effects of different planting patterns on water potential characteristics of soil-plant-atmosphere continuum (SPAC) and yield of summer maize. Three planting patterns were applied, i.e. bed planting (BE), furrow planting (FU) and flat planting (FL). The results showed that although soil moisture content in 0–20 cm ...
