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.

Burirhat, Rangpur during two consecutive seasons of 2004-05 and 2005-06, respectively, to find out suitable row arrangement of carrot with groundnut for higher yield and economic return. There were six treatments, such as sole groundnut, sole carrot, one row of carrot in between two normal rows of  groundnut, two rows of carrot in between two normal rows of groundnut, two  rows of groundnut alternated with two rows of carrot and three rows of  groundnut alternated with three rows of carrot. Results showed that monoculture  produced the highest yields of individual crops but in intercropping system the  highest groundnut equivalent yield (10.63 t/h and 11.10 t/ha) was obtained from two rows of carrot in between two rows of groundnut. The maximum land  equivalent ratio (1.67 and 1.74), the highest gross return (Tk.212600/ha and  Tk. 248400/ha) and net return (Tk.184881/ha and Tk.211680) were also obtained from the intercropping treatment with two rows carrot in between two normal rows of groundnut. But due to higher cost in this treatment, maximum benefit cost ratio (7.09 and 7.01) was obtained from the intercropping treatment    with one row carrot in between two normal rows of groundnut in both the years.

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

The Right

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.

Under the double cropping system, berries usually showed significant quality variations in the summer and winter seasons. In the two-year/four-consecutive-season study, two table grapes of ‘Muscat Hamburg’ and ‘Victoria’ were investigated to determine the phenolic compounds in their berries. Different from those of the summer season, the berries in the winter season suffered no high-temperature stress since veraison to harvest in 2014 and 2015. The variations in the season temperatures led to a higher anthocyanin concentration in the winter season berries of ‘Muscat Hamburg’ grapes than that in the summer berries, while the summer season berries had higher proportions of acylated and methylated anthocyanins than those in the winter season berries. Similar to the anthocyanins, the winter season berries also had a higher flavonol concentration in both varieties. Transcriptome analysis showed that the upregulated genes involved in the flavonoid pathway in the winter season berries were agreed with the changes found in the metabolites. However, the influence of the growing seasons on the flavanols was not consistent in the two varieties, and the variations in VviLARs between the grapes of ‘Muscat Hamburg’ and ‘Victoria’ might be the cause. This research helped us better understand the double cropping system and how the climate factors affected the phenolic compounds in the double cropping system.

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.)

Risk is an important factor in crop rotation systems and cropping system management studies. The study uses stochastic simulation techniques and Stochastic Efficiency with Respect to Function (SERF) to evaluate five crop rotations risk-efficiency and economic sustainability in Sudan Gezira Scheme. Price and yield risk for five crops were simulated to calculate whole-scheme net return. The analysis shows with the present irrigation system capacity 4 course rotation is the most preferred at lower (ARAC) and the 5 Course rotation (B) with 53% land use intensity achieve water distribution equity and is the most risk efficient crop rotation at upper (ARAC). It is downside risk oriented and resilience crop rotation. The area allocated in 5 Course rotations (B) for cotton crop is 17%, wheat 7%, sorghum 60%, groundnut 4% and fodder crops 12%. Fodder can be grown two times in summer and winter season without creating water shortage problems. However, this will increase net return and increase soil fertilities within the selected crop rotation. The result also shows that return pack to night storage irrigation system needs a risk premium of 36 Million (SDG). The techniques used in this study could be used with any distribution estimates for the uncertain variables to incorporate new crop varieties and research recommendation packages. They also could be modified to account for new information contribution during the decision process and account for dynamic effects and policy adjustment and modification.
