This is most easily son with respec-t to varieties in the Highlands, where mzize aid beans have been the subsistence crops of the area for hunclrods of years and whoae is relay tively recent introduction and almost ever consumed in the home. There is a much greater tendency to accept new tollology for the commercial crops than for the maize avd beans. Evidence of this is available from the evaluation study made in the Western Highlands (Ruan , et. al., 1976). &ong the collaborators   971 of the wheat wcs improved varieties while only 31,' of the maize w.,s one of the recoiendned varieties even thov ,h there is a high response from maize variety in the area (Schook, ot. al., 1976). Jo have also established that on the South Coast where maize is primarily a commercial crop sold at harvest, farmers reo.dily accept hybrids1 while in the nighlaids, whore they have historically saved their oin1 . seed, open pollinated varieties are necessary.

      The availability of water in sufficient quantity cnd urnor safe
conditions to bc able to use liquid pesticides is a limiting factor for many small farmers that has previously been overlooked. On the South Coast, where little liquid insecticide had been used, we found a rapid acceptance of r-anulaeted insecticides that can be applied easily with virtually no purchased equipment and without the neo for w ster except for washing hands after use. This seome area faces an , ncute and increasing shortae of labor, and herbicides should be very advantagcoas However, herbicide use is not common, poatially because of the difficulty of application aad the need for sources of water and equipment, If * recommendations for the use of granulated herbicides can be dovehloped, it should be a readily accepted toch'ology, because the yield potential has already been demonstrated, ind. the need ;s a substitute for labor exists.

       Other cultural factor is very important in maize technology in the Highlands. AmenS the traditional farmers, young maize plants arc almost never knowingly destroyed until they can prorido a useful product,  Hence, the farmers plant only a few seeds and then reseed if the number of ple;ato drops too low in any hill. The net result is a less than optimu-! reductiveve population. The usual tcohnicel soiu tion is to plant a ircher than necessary number of seeds and thin aft: r germination to th,. desired number of plants per hill. But for obvious reasons? this meets a tremendous cultural resistance on the part of these farmers, and will probably not be adopted on any large scal--e in this area.
