The influence of rainfall and tillage on wheat yield parameters and weed population in monoculture versus rotation systems.

Extreme climate events (ECEs) of drought are becoming common in Mediterranean areas and farmers need adapt agricultural practices to achieve sustainability. This field study took place in to gain insight into the effects of seasonal rainfall, tillage and crop systems on wheat yield and weed parameters. Conventional (CT), minimum (MT) and no-tillage (NT) systems in wheat monoculture and rotation cropping systems were tested during 3 years of study (2014-2015, 2015-2016 and 2016-2017).

Detection of phytochemical compounds and pigments in seeds and shoots of parasitizing on eggplant.

This study aimed to detect the chemical compounds contained in seeds and shoot parts using the GC-MS following methanol extraction method, and also determining protein, total phenolic, total soluble carbohydrates, plant hormones and pigments for both seeds and shoot (flower and filament). The GC-MS analysis results showed six compounds are common between seed and shoot and the presence of different compounds in different plant parts including 24 compounds in seeds and 9 compounds in the shoot parts. The content of protein and carbohydrate in shoot (1.
