Managerial changes associated with the adoption of Existing Technology I (EMVs) by farmers has already taken adoption of this technology would be minimal, as farmers are already place. Existing Technologies 2 and 3 have been developed and tested, familiar with transplanting techniques. The changes that would have to but adoption by farmers is not yet widespread. In this section, four occur involve reducing the amount of land planted to the first rice crop notional new technologies will be briefly described and evaluated In the in order to provide space for growing a seedbed, increasing the seedling context of Iloilo rainfed farming systems. Each of the notional transplanting age in order to reduce the amount of time the crop Is in technologies is designed to enhance farm productivity, either by the field, and increasing the density of transplanted seedlings, improving the utilization of currently available resources (especially land during the wet season) or by contributing to the alleviation of Atroclimatie requirements. As demonstrated in Figure 8, some of the problems plaguing unacceptable existing technologies. transplanting the second rice crop enables the two-crop sequence to fit mostly within the time period alotted for rice production. The major Notional Technology I Very early maturing varieties (VEVs) difference from previous recommendations for transplanted rice concerns the age of the seedlings upon transplanting. Experimental trials As mentioned previously, early maturing varieties do not provide undertaken at IRRI in 1978 evaluated yield and growth duration effects the opportunity for double rice cropping under rainfed conditions of old seedlings. Average grain yields were significantly reduced when without entailing a substantial risk of yield reduction due to drought old seedlings were used when the transplanting intensity was three stress of the second rice crop (Figure 5). One potential means of seedlings per hill. However, the use of an increased number of allowing double rice cropping under less risky conditions would be to seedlings per hill was found to increase the yield of plots planted with develop varieties with an even shorter maturation period (Figure 9). 40-day-old seedlings to levels similar to those planted with 18-day-old seedlings (IRRI, 1978; Table 31).

Farmers in Iloilo have demonstrated a and capital inputs than are currently employed under single crop progeneral reluctance to allocate land to seedbeds and to forego the more duction systems. Land would become roughly twice as productive as it certain first rice crop for what they consider to be a less certain currently is in areas where multiple rice crop potential is low using outcome for a second rice crop. Furthermore, farmers have been well existing EMVs. versed on the necessity of transplanting EH' seedlings early (18-20 days after seeding). They therefore expect inferior yields using the older 9-n~rbution lo household obeetives. VEVs would contribute an seedlings that form the basis of this new technology. increased supply of rice earlier in the season than late maturing varieties. Initial adopters of such varieties would likely obtain In Iloilo, there is not an overabundance of landless people higher prices for their output due to the early harvest, thusgenerating offering their services as temporary agricultural laborers. In fact, greater farm incomes. Total rice production per unit of land would many farmers with small holdings forego productive opportunities on increase, resulting in an increased overall family food supply. Nutheir own farms in order to work as harvesters in neighboring larger tritional levels may decline, however, if double rice cropping implies a farms. Moreover, it is unlikely that farmers in the area would be reduction in the production of other food crops. willing to increase transplanting wages sufficiently to attract labor that would ordinarily be used in harvesting. Institutional reoulrements. No new inputs, other than seed (which farmers can produce themselves after the first year), would be required In evaluating this technology according to the criteria for for VEVs. Levels of common capital inputs would need to be increased in appropriateness presented at the beginning of this paper, we find that a manner compatible with the growing of two crops of rice in a season transplanting the second rice crop can improve the productivity of land instead of one. Marketing problems may arise, especially for the second (by increasing expected yield) and can reduce the effects of uncertainty crop, due to a lack of adequate capacity of governmental storage on the farming system (by reducing the risk of yield loss due to drought facilities. stress). However, it is not compatible with the level or labor and capital farmers are willing and able to reallocate. nagerial requirements. The managerial requirements for VEVs would be similar to those for varieties currently used by Iloilo farmers. Timing of crop activities will become increasingly important EVALUATION OF UOD.A1.
