Visual Parameters of Soybean (Glycine Max L.) as Influences by Mole Drain Spacing and Depth in Vertisols of Madhya Pradesh

Abstract

Field experiments were conducted at farmer’s fields in Hoshangabad district of Madhya Pradesh during 2010 to 2011 to assess visual parameters and profitability of soybean as influences by mole drain spacing and depth in temporary waterlogged vertisols of Madhya Pradesh. The mole drain spacing selected includes 2, 4, 6 and 8 m and these drains were formed at an average depth of 0.4, 0.5 and 0.6 m from ground surface. The average length of each lateral was 50 m and a 75 hp tractor was operated at a speed of 0.80 km•h-1 during the mole drain formation. Observation on physiological parameters like days to germination, days to 50% flowering, days to 75 % maturity were recorded visually for continuous two seasons, analyzed statistically. On the basis of the results obtained from the experiment, it can be concluded that mole drains at a spacing of 2 meter and at a depth of 0.4 meter was found optimal for better soybean profitability.

Poljski ogledi su izvođeni na farmama u oblasti Hoshangabad u Madhya Pradesh tokom 2010 i 2011 da bi se procenili vizuelni parametri i profitabilnost proizvodnje soje pod uticajem različitog rastojanja i dubine krtične drenaže u povremeno plavljenim smonicama. Izabrane krtične drenaže imale su rastojanja od 2, 4, 6 i 8 m, a drenovi su formirani na srednjim dubinama od 0.4, 0.5 i 0.6 m ispod površine parcele. Srednja dužina svake laterale bila je 50 m, a za formiranje drena korišćen je traktor snage 75 KS koji se kretao random brzinom od 0.80 km•h-1. Tokom dve sezone su posmatrani, beleženi i statistički analizirani fiziološki parametri kao što su broj dana do: nicanja, pojave 50% cvetova i pojave 75% zrelosti. Na osnovu rezultata dobijenih iz ogleda se može zaključiti da su krtični drenovi na rastojanju od 2 mi na dubini od 0.4 m bili optimalni za poboljšanje proizvodnje soje.
