Productivity and nutritive value of field pea In the conditions of Primorsky region
The results of agroecological testing of field pea varieties in the conditions of Primorsky Region are presented. The research was carried out in 2016 on the fields of FSBEI HE “Primorskaya State Academy of Agriculture”. The section has meadow-brown podzolic soil which is heavy in texture. The purpose of the research is to study the biological features of new field pea varieties for Primorsky Region. According to the results of studies in the budding phase and the bob formation, the maximum yield of green mass and absolutely dry matter was noted in the field pea variety of “Nikolka”. The minimum yields of these indicators were noted in the field peas of “Alla”. The highest content of raw fat in the accounting phases was observed in the field pea variety of “Zaryanka”, which is accepted as the standard. According to the content of raw ash, a field pea variety of “Novosibirsk 1” was distinguished. The highest content of К<sub>2</sub>О and Р<sub>2</sub>О<sub>5</sub> is noted in the bean formation phase of field pea of “Nikolka”. According to the digestible protein yield from 1 hectare and the availability of 1 feed unit with digestible protein, the field pea variety of “Nikolka” exceeded the standard in the studied phases of plant development, but it was inferior to soybean of “Primorskaya 86” and vetch of “Omichka 3”, which were the control. The greatest indicator of exchange energy from 1 hectare was obtained from the variety of “Nikolka”, and the lowest - from the field pea varieties of “Alla”. In the conditions of the monsoon climate of Primorsky Region the field pea variety of “Nikolka” was distinguished from the studied pea varieties (“Pelyushka”) in 2016.
