ABSTRACT Forest plantation costs can be reduced by the income from annual crops that are intercropped with trees. An experiment was carried out over two years to assess the viability of agroforestry systems including sabiá (Mimosa caesalpiniifolia), gliricidia (Gliricidia sepium) and maize (cultivar AG 1051). In 2010, the legumes were grown both as monocrops and intercropped (taungya system) with maize in randomized blocks with five replications. Three rows of maize were planted between two rows of each legume (at a spacing of 4.0 m x 4.0 m). In 2011, the legumes were cut down, and the young branches and leaves were added to the areas of intercropped cultivation (alley cropping system). Gliricidia had lower plant height than sabiá. Moreover, while not affecting for gliricidia, intercropping increased plant height for sabiá. Intercropping reduced green ear yield but not grain yield and reduced the cost of introducing reforestation. Intercropping using the alley system reduced the total number and mass of green ears, as well as grain yield, but did not influence the yield of marketable green ears. Finally, producing green ears was more profitable than producing grain and maize monocropping provided a higher net income than intercropping.

ABSTRACT In agroforestry systems, annual plants closest to trees may behave differently from plants in rows that are more distant. This study evaluated the proximity effects of Mimosa caesalpiniifolia (sabiá) and Gliricidia sepium (gliricidia) on corn yield under the taungya and alley cropping systems. The two species were evaluated, in randomised blocks with five replications, in 2010 and 2011, under taungya and alley cropping, respectively. Three rows of corn (left, middle, and right) were grown between two rows of trees. Sabiá trees grew higher than gliricidia trees. The difference in crown diameter between species depended on plant age. There was a linear relationship between plant age and plant height and between plant age and crown diameter for both sabiá and gliricidia trees. In the taungya system, left rows produced more green ears than middle and right rows, but grain yield was higher in middle rows. In the alley system, green ear yield was also higher in left rows than in middle and right rows, but grain yield was unaffected by row position. In both agroforestry systems, there were no differences in corn yield for corn grown between sabiá or gliricidia trees.

The effects of two tillage methods (zero tillage and conventional tillage), two residue managements (residue kept and residue removed) and two levels of cropping system (maize + soybean and sole maize) were studied over 3 years (2015-2017) at Dailekh district of Nepal. Arun-2 and Puja were the varieties of maize and soybean used respectively, followed by winter wheat. The results revealed that the maize + soybean system had significantly higher plant population and ear population (34.83 thousands ha-1 and 34.35 thousands ha-1, respectively), grains per row (37.1), ear length (16.6 cm) and 20.5% higher grain yield as compared to sole maize. The highest maize equivalent yield (7.92 t ha-1) was recorded in maize + soybean as compared to the lower grain yield equivalent (7.06 t ha-1) in sole maize. Zero tillage accounted relatively higher benefits (high net income and B:C ratio) as compared to conventional tillage. The residue kept plot resulted significantly higher B:C ratio (2.41) than the residue removed (2.11) and the maize + soybean recorded 82.5% greater B:C ratio compared to sole maize. Net annual income was significantly higher in zero tillage, residue kept and maize + soybean system (NRs. 223072.00, 222958.00 and 269016.00 ha-1 respectively). Such combinations are recommended for Dailekh district of Nepal to have profitable crop productivity. SAARC J. Agri., 17(1): 49-63 (2019)

Productivity of maize and soil properties change under alley cropping system consisting of four woody species (Gliricidia sepium, Leucaena leucocephala, Cajanus cajan and Senna siamea) at different nitrogen levels (0, 25, 50, 75 and 100% of recommended rate) were studied in the floodplain ecosystem of Bangladesh. Comparative growth performance of four woody species after pruning showed that L. leucocephala attained the highest height, while C. cajan produced the maximum number of branches. Higher and almost similar amount of pruned materials (PM) were obtained from S. siamea, G. sepium and C. cajan species. In general, maize yield increased with the increase in N level irrespective of added PM. However, 100% N plus PM, 75% N plus PM and 100% N without PM (control) produced similar yields. The grain yield of maize obtained from G. sepium alley was 2.82, 4.13 and 5.81% higher over those of L. leucocephala, C. cajan and S. siamea, respectively. Across the alley, only one row of maize in the vicinity of the woody species was affected significantly. There was an increasing trend in soil properties in terms of organic C, total N and CEC in alley cropping treatments especially in G. sepium and L. leucocephala alleys compared to the initial and control soils. Therefore, one fourth chemical N fertilizer can be saved without significant yield loss in maize production in alley cropping system.

The potato crop is sensitive to environmental factors as optimum planting time of potato depends on the most favorable temperatures extending over the longest period of the crop season and requires less than maximum and above the minimum temperatures for emergence after planting. To secure good yield, the potato crop should be planted in such a time that all the three growth and development phases pass through favorable environmental conditions. Cognizant the above facts, a field experiment was conducted at RDRS Farm, Rangpur during 2014 and 2015 for cultivating potato in different dates with two popular potato varieties like Diamont and Cardinal to find out the optimum planting time of potato production in Bangladesh under short duration rice-based cropping system as well as assess the economic viability of potato cultivation in November. The cost-benefit analysis indicates that no major variation was observed in the performance of two varieties e.g. Diamont and Cardinal. But significant variation was observed in different planting dates. The 22nd November planting of both Diamont and Cardinal produced highest yield (29.2 and 28.8 t/ha1 respectively) compared to other three planting dates like 7th November (27.8 t/ha and 26.9 t/ha), 7th December (21.1 t/ha and 19.8 t/ha) and 22nd December (15.2 t/ha and 14.7 t/ha). The 7th November planting was found economically profitable for both the varieties, where the highest economic return was recorded as TK. 2,06,372/ha for Diamont and TK. 2,08,772/ha for Cardinal. Thus, from the economic point of view, the 7th November planting performed best for both varieties. The cost of production was gradually higher in case of late planting due to use of higher amount of pesticides in the crop field. It may be concluded that potato could be cultivated during 1st half of November month, just after harvesting of short duration aman rice in October that will bring harvesting of potato in 1st half of February which can ensure highest net income from potato cultivation and enables farmers to cultivate next crop like mungbean as additional income.

The research compared biomass production and nutrient release in an alley cropping system in two collection methods, the litterbag method and the direct collection method (Morley, Bennett, & Clark, 1964). The system was implemented in 2015 at 2017, at the Maranhão Federal University, Maranhão, Brazil. The experiment was a randomized block design with four treatments, consisting of leucaena+sombreiro (Leucaena leucocephala and Clitoria fairchildiana), leucena+acacia (Leucaena leucocephala and Acacia mangium), gliricidia+sombreiro (Gliricidia sepium and Clitoria fairchildiana) and gliricidia+acacia (Gliricidia sepium and Acacia mangium). In order to determine the remaining dry matter, nutrient release (N, P, K, Ca, Mg and Mn), the decomposition constants and the half-lives times of plant residues, 100 g of fresh material were conditioned in litterbags (50 g of each species), arranged on the soil surface. The second method was done by randomly throwing a collector on each plot in the same dimensions of the litterbags (0.40 x 0.40 m) and collecting the litter. For the two methods samples were collected at 0, 30, 60, 90 and 120 days after the start of the experiment. The litterbags method showed a higher C/N ratio at day 30 up to 120 days, which implies that this method is providing a different environment from the litter, where it would be overestimating the C/N ratio and retarding the decomposition. The G+S and G+A combinations were more rapidly decomposed than the combinations of L+S and L+A. The following order of release was established for the litterbags method: P > N > K > Ca > Mn > Mg, and for the method of collecting the litter: N > P > Ca > Mg > K > Mn.

The yield performance of cowpea var. Minica # 4 (Vigna unguiculata L.) on an Arenic Paleudult (Acrisol) was evaluated in an alley cropping experiment with Gliricidia sepium (Jacq.) Kunth ex Walp., Leucaena leucocephala (Lam.) de Wit and a treeless control during a short- (November-December 2004), and long-(May-June 2005) rainy season at Ebini, Guyana. The alley cropping treatments had no significant effect on cowpea plant height, pods per plant, pod weight per plant and grain weight. During the short-rainy season, values for cowpea plant height and number of pods per plant were higher compared to those for the long-rainy season, and number of pods per plant was positively correlated with pod weight. During the long-rainy season, pod weight and grain weight were correspondingly higher. Plant height vs. number of pods per plant; number of pods per plant vs. pod weight; and, number of pods per plant vs. grain weight, were all positively correlated. Cowpea could yield the same or more when associated with managed fast growing, nitrogen (N)-fixing trees or treeless plots. This alley cropping practice has the potential to reduce the use of fossil-fuel generated fertilizers and reduce the potential production of an important greenhouse gas (GHG).

Background: Mixed cropping of forage grasses and legumes can potentially improve the performance of herbivores. However, the feasibility of grasses mixed-cropped with legumes should be examined at different plant densities. Aim: This study aimed to evaluate the growth characters and forage chemical composition in dwarf napiergrass (Pennisetum purpureum cv. Mott) with Indigofera (Indigofera zollingeriana) grown using alley cropping. Methods: Three densities of dwarf napiergrass with Indigofera, i.e., high density (2 and 1 plants m-2, respectively); medium density (1.33 and 1 plants m-2, respectively); and low density (1 and 1 plants m-2, respectively) were applied under rainfed conditions in Makassar. Results: Plant density significantly affected growth characteristics, such as plant height and tiller density in dwarf napiergrass (p<0.05), and non-significantly affected plant height and branch density (p>0.05) in Indigofera. Plant density did not affect the yielding ability at the first defoliation and annual total of yields (p>0.05), except at the second defoliation when the dry matter production of dwarf napiergrass peaked in the low plant density treatment (p<0.05). In terms of chemical composition, plant density significantly affected fiber concentrations of acid detergent fiber and neutral detergent fiber, which were lowest at low plant densities (p<0.05). The acid detergent lignin and cellulose concentrations tended to be lower at low plant densities, but the differences were not significant (p>0.05). Conclusion: We consider that alley cropping systems for dwarf napiergrass and Indigofera are suitable if low plant densities are employed in the region.
