Effect of irrigation and tillage practices on yield and economics of fodder maize (Zea mays) (original) (raw)

The Effect of Different Irrigation Regimes on the Yield of Fodder Maize (Zea Mays)

A field study was carried out during 2013 season to investigate the effect of different irrigation intervals on fodder maize yield. Randomized complete block design (RCBD) was used, with three replicates. . Four irrigation regimes were executed T 1 =3 irrigations (1 st 20 Day After Sowing (DAS), 2 nd 35 DAS and 3 rd 50 DAS), T 2 =3 irrigations (1 st 20 DAS, 2 nd 40 DAS and 3 rd 60 DAS), T 3 =3 irrigations (1 st 25 DAS, 2nd 40 DAS and 3 rd 55 DAS), and T 4 =3 irrigations (1 st 30 DAS, 2 nd 45 DAS and 3 rd 60 DAS). The results indicated that fodder maize yield varied significantly (P<0.05) under different irrigation regimes. The treatment T 1 resulted the best, plant height (185.33 cm), number of green leaves (13.42), stem width (4.46 cm), and fodder yield (30580 kg.ha -1) While T 2 resulted in the best Seed germination (86.91%). Finally, T 1 irrigation regime was most effective to produce higher fodder yield in maize and the farmers may adopt this treatment to get high fodder prod...

PERFORMANCE OF MAIZE (Zea mays L.) YIELD ATTRIBUTES UNDER VARIOUS TILLAGE STRATEGIES

Tillage is one of the most important practices in agriculture which is done mainly to mix the soil with organic residues and fertilizers, to control weeds, loosen the upper layer of soil, and to create a suitable seedbed for germination and plant growth. The present study was conducted in 2011-2012 at research area of soil and environmental sciences, University of Agriculture, Faisalabad in randomized complete block design (RCBD) having three treatments of minimum tillage (MT), conventional tillage (CT) and deep tillage (DT) with three replicates to evaluate the performance of Maize (Zea mays L.) yield attributes and absorption of different nutrients under various tillage strategies. Maximum effect of tillage practices was observed in the CT and DT that gives the maximum number of leaves, plant height, plant biomass as well as straw yield. The effect of different tillage practices on the harvest index of maize crop was significant. The grain yield of maize was more in case of DT (7.24 ton ha-1) as compared to CT (7.22 ton ha-1) and MT (6.44 ton ha-1). Deep tillage showed better results with reference to performance of maize crop as compared to conventional and minimum tillage.

Effect of different tillage methods on grain yield and yield components of maize (Zea mays L

2007

Abstract: Field experiments were conducted to study the response of grain yield and yield components of corn (Zea mays L.) to different methods. Tillage treatments in the study were moldboard plow + two passes of disk harrow (MDD), moldboard plow + one pass of rotary tiller (MR), two passes of disk harrow (DD), one pass of tine cultivator + one pass of disk harrow (CD), one pass of rotary tiller (R), one pass of tine cultivator (C) and no-tillage (NT) as direct drilling method. The statistical results of the study indicated that tillage method significantly (P 0.05) affected grain yield, number of plants per hectare (NPPH) and number of rows per ear (NRPE), but there was no significant differences in other components such as number of ears per plant (NEPP), number of grains per row (NGPR), ear diameter (ED) and ear length (EL). The maximum value of grain yield 1 (4.15 t ha), NPPH (39830) and NEPP (0.92) was obtained in case of MDD treatment, while maximum value of NRPE (14.9) and ED...

The Effect of Fertilization and Irrigation on Maize(Zea mays L.) Production

Acta Agraria Debreceniensis

In a long-term field experiment set up at the Látókép experimental station of the Center of Agricultural Sciences of Debrecen University, the data of the last five years (1995-1999) were analyzed to determine the crop production factors with the greatest influence on maize production and the relationship and interactions between irrigation and fertilization.In the extremely dry year of 1995, fertilization was found to cause substantial yield depression in the absence of irrigation. According to results of analysis of variance, fertilization significantly reduced the maize yield by 40-90% compared to control plots. Under irrigated conditions, there was a considerable increase in the maize yield, the yield surplus being 4.4-9.4 t ha-1, depending on the nutrient supply level.During the period from 1996-1999, when rainfall conditions were favorable for maize, fertilization significantly increased the maize yield even without irrigation over the average of the four years. The yield surpl...

Influence of different tillage systems on yield of corn (Zea mays): an overview

2014

Corn (Zea mays L.) is the world’s most important crops after wheat, barley and rice. Among the factors that influence corn productivity is tillage practices. Tillage operation affects the physical properties of soil structure and will change specific gravity of soil, apparent tolerance and thermal conductivity. Also reports showed that tillage effects had advantages on water distribution, porosity, root distribution and crop yield. Change in soil porosity leads to the change in soil aeration or air transfer and water soluble into the soil which may reform the crop production. Researchers reported that no tillage causes the decrease of soil porosity space which can have reverse effect on the rain fed crop yield. Between 1970 and 1980 there appeared considerable changes in the concept of tillage requirement for produce of products. These changes were energy consumption reduction and use of minimum tillage methods which often lead to reduction of soil erosion, and also no tillage for s...
