CHICK-PEA CULTIVATION IN THE NORTHERN FOREST-STEPPE OF TYUMEN REGION
The chick-pea seeds germination and the chick-pea plants viability, the chick-pea crops weed infestation, the yields and mass of 1000 chick-pea grains, as well as the economic efficiency of the crop cultivation, depending on the depth and methods of soil tillage have been studied. The highest percent of chickpea germinating capacity (86.6 and 82.9%) was obtained with mouldboard soil cultivation. The reduction of the tillage depth to 12-14 cm resulted in the decrease of chick-pea germinating capacity by 7.6-14.1 and 8.8-13.4%, compared to the control. The highest percent of chickpea viability - 94.7 and 91.3% was obtained in trials with mouldboard tillage (plowing, 20-22 cm - control options). The reduced depth of soil cultivation led to increased weed infestation of chickpea crops with all the soil treatment methods used. The results of the study demonstrated that, the most economically sound method of chick-pea growing was the option with mouldboard soil cultivation (20-22 cm), with the profitability level being of 58.7% and the return of - 11,737 rubles/ha.
