Abstract

Field experiment was carried out during Kharif 2005 and 2006 using different herbicides to study the response of weed control treatments in maize and cowpea intercropping system for quality fodder. Pre-emergence application of alachlor, metolachlor and pendimethalin @ 1.00 and 1.50 kg a.i./ha each and post emergence application of imazethapyr @ 0.10 and 0.15 kg a.i./ha at 20 days of crop sown combined with weedy and weed-free conditions. All the herbicides at each dose effectively controlled the weeds and reduced its dry weight as compared to weedy condition. Alachlor, metolachlor and pendimethalin at 1.5 kg a.i./ha and pendimenthalin at 1.0 kg a.i./ha significantly reduced the population and dry weight of total weeds over the other rates of herbicides. Pendimethalin @ 1.5 kg/ha gave maximum green forage and dry matter yield (448 and 102 q/ha) among herbicide treated plots which were at par with that of weed free condition (466 and 109 q/ha). All the herbicides at higher doses followed the same trend in reduction of dry matter accumulation of weeds and increased in green forage and dry matter yield of maize and cowpea mixed fodder over control. Similarly, with increase in the dose of herbicide the crude protein, nitrogen uptake and DM (dry matter) percent increased significantly.

Abstract

Agroforestry has been defined as a dynamic ecologically based natural resources management system that through the integration of trees on farms and in the agricultural landscape diversifies and sustains production for increased social, economic and environmental benefits for land users at all levels. This paper highlighted agroforestry practices and concepts in sustainable land use systems. The benefit derivable from the interface between forest trees and agricultural crops are enormous. They include the optimal use of land for both agricultural and forestry production on a sustainable basis including the improvement of the quality of soil. This is in addition to the socio-economic benefits that are accruable from agroforestry. Indeed the advantage of agroforestry is all encompassing and germane to a sustainable production system and livelihood.
