Responses of Guar to Supplemental Irrigation in Heavy Clay Soils of Abu Naama
Journal Title: IOSR Journal of Agriculture and Veterinary Science (IOSR-JAVS) - Year 2018, Vol 11, Issue 9
Abstract
A field study from 1999 through 2001 was carried out to investigate three water regimes effects on the performance and yield of guar [Cyamopsis tetragonoloba (L.)Taubert], using a randomized complete block design with four replications. The water regime treatments studied were; fully-irrigated, one supplemental irrigation and rain-fed. In the research reported here, most of the parameters namely; plant height,number of pods per plant; biomass and grain yield is presented. Consistent significant differences between the fully-irrigated and rain-fed treatment (P = 0.05) was noted, in which rain-fed exhibited low results as compared to fully-irrigated. However, one supplemental gave variable effect on the parameters mentioned earlier. Nevertheless, weight per seed and harvest index showed no response to the three water regimes. When the data of the three seasons were subjected to combined analyses, it was observed that the yield reductions in one supplemental irrigation and rain-fed from fully-irrigated were 18% and 42% respectively. The three seasons differed significantly (P = 0.01) with regard to all the parameters of the plant studied, except the harvest index. The differential response of grain yield of guar in each of the three seasons and combined data analyses to the three water regimes, follow similar trends as in biomass or total dry matter at harvest. Consequently, the biomass can be regarded as an indicator of guar crop yield. On the other hand differences in guar yield can be attributed entirely, to number of pods per plant. Finally this study, clearly suggest that it is necessary to provide one to three irrigations to guar crop depending on the growing environmental conditions of the seasons
