Intercropping Systems in Mango Orchard for Rainfed Area of Central India
International Journal of Horticulture, 2013
The experiment was conducted to assess the effect of intercrops on growth characters (plant height, girth and canopy area) and yield of main crop mango and vise-versa. The intercrops influenced the growth of main plants and increase in plant height and canopy area of the mango and it was found maximum with paddy followed by black gram intercrops. However, the canopy of the base crop also affects the growth and yield of intercrops and it is observed that the under canopy intercrops performed poor compared to open field. Fruit yield and return out of sold fruits of mango were found maximum with intercrops blakgram. Maximum number of fruits was observed with intercrop blackgram whereas, maximum average fruit weight was found in pigeon pea. The maximum net return, paddy equivalent yield and B:C ratio were obtained from intercrop ginger. The nutrient status of orchard soil also found improved after intercropping.
Performance of intercropping in pre-bearing mango orchards under drip irrigation in a degraded land
Journal of Applied and Natural Science, 2018
A field experiment was carried out to evaluate the performance of pre-bearing mango plantation with different intercrops (papaya, pineapple and combination of papaya and pineapple) in a sandy clay loam soil on a degraded land under drip irrigation at ICAR-Indian Institute of Water Management, Bhubaneswar, Odisha during 2017-18. Different intercrops planted in the mango (cv. Amrapali) were (i) two rows of papaya (cv. Red lady) in either side of mango plants, (ii) two paired rows of pineapple (cv. Queen) in either side of mango plants and (iii) one row of papaya and one paired row of pineapple in either side of mango plants with and without paddy straw mulch. All plants were irrigated by drip irrigation (DI) system. The amount of water used in mango–papaya cropping system (1220 mm) was higher than that in mango-pineapple cropping (975 mm). The volumetric soil water content in top 0.60 m soil in mango, papaya and pineapple were 20-23%, 21-24% and 22-24%, respectively. The vegetative gr...
Important of applying intercropping for sustainable crop production: A Review
International Journal of Research in Agronomy, 2021
Intercropping is the cultivation of two or more crops at the same time in the same field. Its advantages are risk minimization, increased income and food security, reduction of soil erosion and pest and disease control. Because of these advantages intercropping is practiced in many parts of the world, especially in the developing countries. Therefore, this paper is aimed to review the advantages of intercropping for sustainable agriculture. In Ethiopia fruit trees are intercropped with all types of short-term crops such as beans, peas, potatoes, maize, millet, exotic and indigenous vegetables when they are still young as a way of attaining food security and income before the trees mature. Besides this intercropping provides high insurance against crop failure, especially in areas subject to extreme weather conditions such as frost, drought, flood, and overall provides greater financial stability for farmers, making the system particularly suitable for labor-intensive small farms. Furthermore, because of some favorable exudates from the component legumes, greater land-use efficiency, greater yield stability and increased competitive ability towards weed, intercropping is advantageous over mono-cropping.

Mango (Mangifera indica L.) based agroforestry system offers spatial advantage for intercropping in Indian subtropics. Mango is planted at wide spacing to accommodate the large crowns needed to support the fruit yield. Wider spacing of the trees provides the vacant space to the orchardist to grow suitable and synergistic crop (vegetables/ medicinal plants) to supplement his income. The present investigation was done to screen out the best intercrop out of the four crops, viz. ginger, turmeric, kalmegh and stevia that can be grown in old mango orchards. The experiment was laid out at Experimental Farm of Advance Centre for Horticulture Research (ACHR), Sher-e-Kashmir University of Agricultural Sciences and Technology, Udheywala, Jammu, which is located at an altitude of 327m above mean sea level, between 32073´ N latitude and 74087´ E longitude. Mango orchard selected for the study had a very dense canopy and thus the interception of light was only 30-40 percent than that in the open...
Study on Papaya Based Intercropping and Its Economics at Farmer's Field in West Bengal, India
A survey was carried out to evaluate different papaya based intercrops as well as their benefit cost ratio at farmer's field in North 24 Paraganas and Nadia District in West Bengal during 2007-2008. It was found that papaya based intercropping was accepted by the farmers due to secondary source of income from papaya. Vegetables such as chilli, brinjal, colocasia, elephant foot yam, bottle gourd and pumpkin as intercrops were observed in papaya field in West Bengal condition. From the results of survey from 20 orchards of papaya, it was clear that most of the farmers (about 79%) practised in papaya-chilli intercrops followed by papayabrinjal in first year i.e. in early vegetative stage. The papaya plants are retained up to second year to get yield and the tall papaya plants (5-7 m height) are then used as pole for making suitable structure/mancha to raise bottle gourd. During second year, they planted pumpkin, colocasia and elephant foot yam in late fruiting phases. Comparative study of benefit cost ratio per hectare of sole (pure) crop (1.82) and papaya based intercrops (2.1) was also calculated on the basis of farmer's observations. It was also found that the papaya plants were infested with mosaic virus when intercropped with chilli and brinjal.

An attempt was made at ICAR RCER, Research Centre, Ranchi to analyse the plant growth behavior, productivity of different component crops, profitability, soil fertility status and carbon sequestration potential of 20 different agri horticultural systems during young bearing stage (6th to 10th year) of mango plants. The field trial was established during the year 1999-2000 to standardize suitable filler crop and intercrop combinations for mango based agri-horticultural systems under rainfed uplands of eastern plateau and hill region. The study indicated enhanced growth of mango and filler plants with paddy as intercrop. With respect to soil fertility, reduction in the content of available nitrogen and potassium was recorded after 10 years of planting particularly under Mango + Guava + Paddy agri-horticultural system. Among all the systems, the maximum cumulative Rice equivalent yield was recorded under Mango + Guava + French Bean. During all the five years, the significantly higher R...

Investigations were undertaken at Ranchi of Jharkhand state of India to test the efficacy of mango genotypes Amrapali and Latra be used as interstocks for reducing the plant size of vigorous but popular mango varieties viz. Langra, Himsagar and Bombay Green under eastern plateau and hill conditions of India. Data on plant growth parameters during 2012-13, 2013-14 and 2014-15 indicated decrease in rate of growth of plant height, canopy spread, girth of rootstock, girth of interstock, girth of scion, average length of shoot extension growth in cultivars Himsagar and Bombay Green with interstock of Amrapali. Hence, it was concluded that mango cultivar Amrapali can be effectively used as interstock for reducing plant vigour of mango cultivars Himsagar and Bombay Green.
Food shortage is known to have been caused by limiting factors such as inappropriate planting time, diseases and insect pests, use of low yielding varieties, etc in Ethiopia. In areas facing food insecurity, such as Africa, farmers have practiced intercropping since old times. The study was aimed to improve productivity and profitability of tomato/maize intercropping by determining their best compatible combination and right intercropping time for sustainable production of the crops in the area. Treatments consisted of factorial combinations of three component populations of tomato (T) and maize (M) i.e. (100T:50M, 67T:33M and 50T:50M) and five maize intercropping dates (30 DBTT, 15 DBTT, ATT, 15 DATT and 30 DATT) together with their respective sole crops and laid out as Randomized Complete Block Design (RCBD) with three replications. Determinate tomato and early maturing maize were used for the intercropping system. The highest total LER value of 2.06, with GMV of 171,077.73 Birr/ha and MA of 88,030.29 Birr/ha was obtained from component populations of 100T:50M. However, the highest GMV of 216,065.00 Birr/ha and MA of 144,044.00 Birr/ha was obtained from sole tomato crop. Although, sole tomato production would be beneficial in the study area, the 100% tomato population with 50% maize by intercropping maize 15 days after transplanting of tomato is a promising treatment in order to minimize risks where farmers fear risk of sole crop due to disease or market conditions.
Study of Yield Advantage of Intercropping Over Sole Cropping Under Rainfed Condition
Abstract: The present research work on intercropping has mostly focused on the suitable crop geometry and nutrient levels on mustard plus chickpea intercropping system. The experiment was laid in split plot design in intercropping of Mustard plus chickpea with two row ratios i.e. 1:1 and 2:1, which constitute main plot and three levels of Nitrogen (control- no fertilizer, 20 kg Nitrogen and 40 kg Nitrogen per hectare). A uniform dose of Phosphorous at the rate of 40 kg P2O5 per hectare in the form of SSP and 20 kg K2O per hectare as Murate of Potash was applied at the time of sowing. In addition to intercropping two sole crops of Mustard and Chickpea were allocated randomly in each replication for comparison. The assessment of row ratio and yield advantages reveals that through the yield attributes, yield per se of component crops in intercropping systems were reduced as compared to those of sole crops, the combined equivalent yield of component crop in intercropping system exceeded the higher sole crop yield. The yield of the component crops in intercropping systems reduced as compared to those of sole crop. The combined equivalent yield of component crop in intercropping system exceeded the sole crop yield. The studied intercropping system (mustard + chickpea 1:1 ratio) was the best for yield (equivalent yield 1776 kg/ha) and economic return (Rs. 22095/- per ha.).
