“…This agrees with report by Snapp et al, (2003) that cereals intercropped with long-duration pigeonpea are generally harvested toward the end of the rainy season, and the pigeonpea develops rapidly on residual moisture after the harvest of the companion crop and in some areas ratoon system is used for a second crop harvested in the subsequent season. This agrees with Chauhan et al, (1996) who reported significantly positive relationship of total ratoon yield to main crop yield. The higher grain yield in the ICRISAT medium-and short-duration genotypes compared with the Nsukka Local genotype under main crop and ratoon crop conditions were attributed to their genotypic characteristic high yield attributes for which they were bred (Upadhyaya et al, 2006).…”

“…The higher pigeonpea grain yield in the main crops compared with their ratoon crops was attributed to higher plant vigor in the main crops. The 63.6% average ratoon crop yield of the main crop in this study was higher than the 50% ratoon crop yield reported in some short-duration pigeonpea genotypes by Chauhan et al, (1996) in India.…”

“…Tabo et al, (1995) observed commonly grown perennial types that remain in the field for two years among Nigerian traditional farmers. Studies on ratoonability in pigeonpea genotypes have been reported under Indian conditions (Sharma et al, 1978, Chauhan et al, 1996 but there is dearth of such information under the Nigerian condition. This study was carried out to assess the grain yield of improved and local pigeonpea genotypes under intercrop and sole crop conditions and the ratooning ability of the pigeonpea genotypes from such cropping systems.…”

Five improved pigeonpea genotypes obtained from ICRISAT of short-and medium-duration and a Nsukka local long-duration genotype were assessed for their grain yield in mixtures with two maize genotypes (hybrid and open pollinated types) and as sole crops in 2006 at Nsukka, Nigeria. The 2006 pigeonpea plants were maintained as sole crops for ratoon crop assessment in 2007. The pigeonpea genotypes were combined with the two maize genotypes for mixture treatments and also maintained as sole crops in a randomized complete block design (RCBD) experiment with three replications. The results showed that maize intercropping significantly (P<0.05) depressed the number of primary branche, leaves and grain yield in pigeonpea in the main crop. Percentage ratoon plant survival was significantly (P<0.05) higher in pigeonpea plants that were intercropped with open pollinated maize compared to those intercropped with hybrid maize and those planted as sole crops. The percentage ratoon plant survival was significantly (P<0.05) higher in the long-duration pigeonpea genotype compared to those of the short-and medium-duration types which were statistically similar. The ICRISAT short-and medium-duration pigeonpea genotypes had significantly (P<0.05) higher grain yield compared to the long-duration genotype in the main crop and maintained a higher grain yield in the ratoon crops too, but without any statistical significance. Ratoon crop grain yield was on the average, 63.6% of the main crop. Grain yield performance in the pigeonpea genotypes was mediumduration genotypes>short-duration genotypes>long-duration in both the main and ratoon crops.

“…A high variability in yields from the ratoon crop suggests that more selection is needed for yield stability (Sharma et al 1978). One possible selection indicator may be high leaf area retention in the original crop, as was observed for short duration pigeonpea varieties in Andhra Pradesh, India (Chauhan et al 1996).…”

The management of staple crops as perennials is a historic legacy and a present-day strategy in some regions of Sub-Saharan Africa, yet perenniality is rarely an agronomic subject. Farmers in Malawi cut annual crops, such as pigeonpea and sorghum, to extend production for more than one growing season. Cassava, a perennial food crop, has a proven track record of abating hunger. Here we review ratooning, as well as the historic role of perennial staple crops in Malawi. Ratooning is a method of harvesting a crop which leaves the roots and the lower parts of the plant uncut to give the ratoon or the stubble crop. This review is completed with interviews with Malawian farmers. The major points follow. The management of staple crops as perennials is underserved by research. Indeed, we retrieved only 86 references on ratooning sorghum and pigeonpea. Of these, 9 % and 19 % respectively were from the African continent. The literature and interviews indicate that pigeonpea and sorghum have high productive potential when well managed in ratoon systems. Thirty-five percent of interviewee responses that supported ratooning mentioned saving seed. Other primary reasons to ratoon include stimulating regrowth (30 %) and saving labor (20 %). However, 31 % of responses that were against ratooning cited increased disease potential, as well as excessive vegetative regrowth (18 %).

(Yadav et al, 1994). Ratooning also has been tested for production of pigeonpea [Cajanus cajan (L.) Huth] (Chauhan et al, 1996) and lima bean (Phaseolus lunatus L.) (Beverly and Byous, 1992). Among the Solanaceae, ratoon cropping sometimes is practiced on eggplant (Solanum melongena L.) (Dhankhar et al, 1980).…”

Studies were conducted to examine the effects of pruning treatments applied to spring-transplanted bell peppers (Capsicum annuum L.) on marketable fruit yield in late summer and fall. Control plants were set in the field in early May 1997 (Oklahoma) and Apr. 1998 (Oklahoma and Texas) and harvested weekly into October (Oklahoma) or periodically into December (Texas). In 1997, all four treatments (involving height and method of pruning) reduced total marketable fruit weight, but differences among treatments were nonsignificant. In Oklahoma in 1998, plants were mowed on 27 July at an average height of ≈24 cm. Mowed plants produced less total marketable fruit weight but more U.S. Fancy fruit than did control plants, while weight of U.S. No. 1 fruit was not affected. In Texas in 1998, plants mowed on 4 Sept. at a height of ≈20 cm produced more than twice the weight of U.S. No. 1 fruit and fewer cull fruit than did control plants. Nonpruned transplants set in the field in Summer 1998 (both Oklahoma and Texas) produced low marketable yields. Maintaining spring-transplanted bell peppers is a viable technique for fall pepper production, and the highest total marketable yields may be obtained if these plants are not mowed. However, mowing offers an opportunity for increased fall production of premium fruit, and mowed plants would be easier to manage than nonpruned plants.
