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.
An experiment was conducted in farmers fields to investigate the effects of intercrops on the yield of mango cultivar 'Baneshan' with the aim to maximize the production potential and economic returns from mango-based intercropping systems in various villages of Nuzvid mandal, Krishna District, Andhra Pradesh. The treatments include, Mango + Horsegram, Mango + Bhendi, Mango + Beans, Mango + Brinjal, Mango + Tomato, Mango + Tobacco, Mango + Paddy and Mango + Maize. All the intercrops were sown / transplanted during rainy season only (Kharif). Cultivation of tomato as an intercrop in mango orchard recorded significantly highest mango yield (6222.20 kg/ha) followed by brinjal (5951.37 kg/ha) than the other intercropping systems. The lowest yield (3791.64 kg/ha) was recorded with maize as an intercrop. The highest monetary net return (Rs. 143138.90/ha) and BCR of 2.72 was obtained with brinjal intercroppping in mango orchard. Intercropping was effective in sustaining income and employment generation especially during the pre-production phase and "off" year especially for small and marginal farmers. Thus, intercropping in mango orchards can help farmers for year round production, employment, reduced cost of cultivation and increase monetary returns besides providing nutritional security.

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...

An investigation was carried out on sandy loam soils of tarai regions of Uttarakhand to analyze the potential of drip irrigation along with mulch technically as well as economically. The treatments of the study were comprised of four irrigation levels (0.3, 0.4, 0.5 and 0.6 P.E) with mulch (silver/ black-100 micron) and non-mulch conditions along with control (100% P.E). The study revealed that drip irrigation along with mulch showed better performance in terms of yield, water use efficiency as well as economics. Maximum yield of 18.72 t/ha along with maximum net return of Rs 213990.94 per hectare and B: C ratio of 4.20 was recorded in T 7 (0.5 P.E along with mulch). So the experiment suggests that drip irrigation along with mulch has the potential to provide greater benefit by optimizing the use of water resources.
Many techniques have been and are being made to find alternatives to water-saving practices. Among them, Partial root drying (PRD), one of the effective approaches, plays a major role in reducing the harmful effects of water deficit stress. An experiment was carried out using irrigation strategies [I1 (100% full irrigation “FI”), I2 (75%FI), I3 (50%FI), and I4 (PRD (50%FI)] and soil organic mulch [L0 (Zero layer organic soil mulch” control”), L1 (Single layer organic soil mulch), L2 (Two layers of organic soil mulch), and L3 (Three layers of organic soil mulch)] to inspect the impact of those treatments for increasing yield, water productivity and saving energy under arid region conditions. To meet the study's objective, two field experiments were carried out at a private farm. Our results demonstrated a general decrease in water stress and salt accumulation inside root-zone area with PRD with L3. The PRD strategy increased fruit yields by 3.7 and 7.3% and water productivity by ...

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...
