The imbalance between the crop production and population growth is currently the major issue in Ethiopia. To feed the growing population, increasing the production of food through growing more crop types in the same field as an intercropping is the right strategy. The study was aimed at evaluating the profitability of sorghum-legume intercropping on yield of sorghum. Intercropping sorghum with legumes crops increases the land productivity as its Land Equivalent Ratio is greater than one. In these cases, the land equivalent ratio is greater than one indicating the benefits of intercropping.  In general, legume crops contributed to the yield of sorghum either intercropped with legume or grown up using residual contribution of legumes after a year. Therefore, for maximum sorghum production, farmers should plant either as intercrop or after residual effect of legumes crops. In addition to agronomic parameters used to compare the advantages of any cropping system in small scale farming conditions, total gross monetary value is also used to evaluate economic advantages of intercropping system.

The imbalance between the crop production and population growth is currently the major issue in southern Ethiopia. To feed the growing population, increasing the production of food through growing more crop types in the same field as an intercropping is the right strategy. The current study was aimed at evaluating the effect of sorghum-legume intercropping and its residual effect on yield of sorghum. The land equivalent ratio was calculated for sorghum intercropped with pigeon pea and cowpea. Intercropping sorghum with pigeon pea and cowpea increases the land productivity as its Land Equivalent Ratio is greater than 1. In both cases, the land equivalent ratio is greater than 1 indicating the benefits of intercropping. The residual effect of sorghum intercrop with legumes was evaluated on the yield of sorghum. Although there was no statistically significance differences on yield and yield component of sorghum, sorghum planted on the plot of pigeon pea and cowpea sole has 44.6% and 27.8% yield advantage relative to sorghum alone respectively. Planting sorghum under sorghum-cowpea intercropped condition increase the yield of sorghum by 41.8%. The result also shows 74.0% sorghum yield change was observed when planted after intercropped condition of sorghum with pigeon pea. The productivity of sorghum also increases when planted on the plot of sole legume. The current finding in general shows that legume crops contributed to the yield of sorghum either intercropped with legume or grown up using residual contribution of legumes after a year. Therefore, for maximum sorghum production farmers in the area should plant either as intercrop or after residual effect of legumes. Int. J. Agril. Res. Innov. Tech. 9(2): 62-66, December 2019

Strip Intercropping

Pigeonpea is an important grain legume, and is traditionally intercropped with maize in West Africa and India. Small farmers in Limpopo Province, South Africa, who cultivate pigeonpea landraces under traditional mixed intercropping, experience the challenge of low productivity. Strip intercropping is a novel cropping system has greater efficiency and productivity in resource utilization when compared to mixed intercropping. Therefore, this study was conducted to evaluate the performance of improved pigeonpea varieties under a pigeonpea-maize strip intercropping system. Five pigeonpea varieties (ICEAP 001284, ICEAP 00604, ICEAP 87091, ICEAP 00661 and ICEAP 01101-2) were intercropped in maize as mixed and strip intercropping during the 2015–2016 and 2016/2017 cropping seasons while monocrops of both crops were also maintained as control. The trial for each season was replicated three times in a split plot design. During both seasons, ICEAP 001284 and ICEAP 00604 exhibited the shortest number of days to attain 50% flowering under strip intercropping and monocropping when compared to the remaining varieties. Higher significant (P < 0.05) grain yields (1726 kg ha-1, 1478 kg ha-1 and 858 kg ha-1 were obtained under strip intercropping for ICEAP 001284, ICEAP 01101-2 and ICEAP 00604, respectively during 2016/2017 than their respective grain yields during 2015/2016 season. Strip intercropping out-performed mixed intercropping with a higher land equivalent ratio and cash returns due to its ripple effect in the enhanced yield components. Among the five pigeonpea varieties, ICEAP 001284, ICEAP 00604 and ICEAP 01101-2, performed exceedingly well in their crop mixtures. In conclusion, the three pigeonpea varieties were selected for cultivation under strip intercropping. Strip intercropping exhibited greater efficiency in resource utilization and productivity over mixed intercropping in terms of grain yield, land equivalent ratio, net profit, and benefit-cost ratio. © 2021 Friends Science Publishers

SUMMARYStudies were carried out at Kalyani during 1982–83 and 1983–84 to evolve a multiple cropping system with cotton as the main crop. Cotton was intercropped with paddy, greengram, blackgram, peanut and soyabean in the rainy season, and these were also grown as solccrops followed by crops of peanut, lentil, chickpea, wheat and mustard, respectively, in the winter season. All plots were subsequently cropped with sesame in the summer season. There was an increase in total grain yield, land equivalent ratio (LER), area time equivalent ratio (ATER) and relative net return (RNR) values when legumes and cereals were intercropped with cotton. The yield of the winter crops grown with the help of residual soil moisture was in the order: chickpea > mustard > lentil > wheat > peanut. Sesame yielded best after the chickpea and blackgram sequence and yielded almost as well after the lentil and greengram. The greatest net return was obtained from the cotton and paddy (1:1) intercrop followed by sesame.

SUMMARYThe effects of intercropping roselle with blackgram, cowpea, soyabean, groundnut and sesame under single, double and triple row planting patterns and at three different intercrop sowing dates were studied from 1983 to 1985. The fibre yield of roselle was reduced by intercropping. The reduction was least with groundnut and greatest with cowpea but was compensated for by the yield of the intercrops. Double and triple row planting systems favoured the productivity of both roselle and the intercrops, increasing the Land Equivalent Ratio (LER) of the cropping system. The best yields of roselle were obtained when the intercrops were sown 15 days after the roselle.

<p>Intercropping is one way of increasing land productivity. The research was aimed to determine the suitability of soybean promising lines for maize + soybean intercropping based on land productivity assessed by land equivalent ratio (LER). The research was conducted at Kendalpayak Station Research, Malang, in February to May 2016, using factorial randomized block design, repeated three times. The first factor was cropping system (monoculture and intercropping), the second factor was 55 soybean genotypes. Spacing for maize in the intercropping system was 2.2 m x 0.5 m x 0.2 m, and for soybean was 0.35 m x 0.10 m. In monoculture, spacing for maize was 0.75 m x 0.25 m and for soybean was 0.35 m x 0.10 m. The results showed there was five genotypes suitable for intercropping of maize + soybean based LER value, ie G//IT7-3, M0706//MI196-3, M0706//MI197-4, M0706//MI199-1, and M0706//MI199-2, with LER value of more than 1. Intercropping of maize with these soybean lines, gives a higher land productivity than monoculture.<br /><br />Keywords: Glycine max (L.)

A field trial was conducted to validate some fertilizer application approaches for Boro-Green manure (GM) -T. Aman cropping system at the Bangladesh Rice Research Institute (BRRI) Farm, Gazipur (AEZ-28: high land) during the period from Boro 1999-2000 to T. Arnan 2000. Five different application approaches of inorganic and organic fertilizers along with their residual values were evaluated. A positive effect of GM on the yield of T. Aman rice was observed. Application of cowdung (CD) @ 6 t/ha (at 15 % moisture) along with integrated plant nutrient system (IPNS) based chemical fertilizer in Boro season followed by green manuring with dhaincha (in Kharif-l season) and then growing T. Aman rice (in Kharif-ll season) with reduced doses of chemical fertilizer (60% N, 50% P, 50% K, and 50% S) substantially increased grain yield and narrowed down the N, P, and K balance in soil. This fertilizer application approach may be practiced for sustainable crop production. No appreciable yield loss in T. Arnan rice (2nd crop) occurred due to the application of reduced doses of P, K, S, and Zn indicating the beneficial residual effect of fertilizer applied to the first crop (Boro rice) of the cropping pattern. The N uptake was in excess of the N added as fertilizer. An improved balance of P, S, and Zn was observed. But the K balance was negative. However, application of cowdung and incorporation of dhaincha slightly improved the K balance of the soil. The highest gross return of Tk. 86,270 was obtained with the above practice (treatment T4)Key Words: Chemical fertilizer; application; wet land rice.DOI: 10.3329/bjar.v34i1.5747Bangladesh J. Agril.

Using the right spatial arrangement is a sustainable way to prevent or at least delay the emergence of weeds in the crop production. This study evaluated the influence of row spacing and plant density of maize on weed control based on the phytosociological survey. It was conducted on an Oxisol textured medium in a 400 m2 area under semiarid conditions. The hybrid maize 30F53YH was managed under a no-till cropping system with three types of row spacing (0.35 m, 0.50 m, and 0.70 m) and three plant densities (5.0 plants m-2, 6.5 plants m-2, and 8.0 plants m-2). The experimental design was randomized complete blocks with four replications in a factorial arrangement 3 × 3. The phytosociological survey of the weeds was randomly performed four times in each subplot, using the inventory square (0.5 m × 0.5 m). The collected data were analyzed using the R statistical program. Among the specimen’s families identified on the field, three of them need to be highlighted due to its high values of density, frequency, and dominance. These families were Fabaceae, Poaceae, and Amaranthaceae. Also, it was identified that the Leucaena leucocephala species may be classified as a weed, as it acted as an invasive species on maize. The weed control was greatly influenced by the interaction of both parameters rather than only row spacing or the plant density factor. The results showed that the reduced spacing and high crop population decreased the presence of weeds in the maize crop.

AbstractNitrogen, a vitally important plant nutrient, is subject to various losses that affect its efficiency. We tested prilled urea (PU), urea supergranules (USG), green manures (GM) and farmyard manure (FYM) in a rice-wheat cropping system to determine which were the most efficient and economical N sources. The maximum rice growth, yield and N-uptake occurred with USG and with GM (Sesbania rostrata) plus PU. Incorporation of GM saved 60 kg N/ha. On the following wheat crop, GM (S. aculeata) plus PU and FYM plus PU had the highest residual effect on the number of tillers per m2, and straw and grain yield. An increase in N recovery efficiency occurred with combined use of PUand organic Igreen manures compared with PU alone. In areas where USG is costly or unavailable and FYM is scarce, green manures can be a cheap N source that allows small-scale farmers to get sustainable yields in a rice-wheat rotation.

Establishment of huge number of biogas plant in the recent years in Bangladesh creates a burden to disposal of bioslurry. An attempt was undertaken to explore the usability of bioslurry in agricultural crop production under potato-rice system as well as to reduce bioslurry induced pollution. The experiment involved a sole chemical fertilizer treatment, four treatments based on integrated plant nutrition system with 5 t ha-1 cowdung and cowdung bioslurry and 3 t ha–1 poultry manure and poultry manure bioslurry, and a control. The potato crops received manures or slurries, and its residual effect was evaluated on the succeeding T.Aman crop. Poultry manure bioslurry, poultry manure, cowdung bioslurry and cowdung gave 22.5, 20.0, 9.9 and 2.9 % increase in total system productivity, respectively over sole chemical fertilizer treatment. Bioslurries had higher contribution compared to their respective original manure. Bioslurry was found very useful as manure for crop production.Res. Agric., Livest. Fish.2(1): 27-33, April 2015
