Performance of mango based agri-horticultural models under rainfed situation of Western Himalaya, India

Abstract

A total of 15 years of experimentation period (1995)(1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010) was divided into two phases. In the first phase (1995)(1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005), five mango based agri-horticultural models (AHM) viz. Mango ? cowpea-toria, mango ? cluster bean/okra-toria, mango ? sesametoria, mango ? black gram-toria and mango ? pigeon pea in addition to sole mango plantation (no intercrop) and in second phase (2005)(2006)(2007)(2008)(2009)(2010), two mango based AHM (mango ? colocasia and mango ? turmeric) in addition to sole mango (no intercrop) were studied. The mean maximum cowpea equivalent yield (t ha -1 ) was harvested from cowpea (1.84) followed by okra (1.21), black gram (1.11), sesame (0.68) and mean minimum with pigeon pea (0.58). The crop yield reduction among the mango based AHM was observed from third year to tenth year. The positive correlation was found between light transmission and intercrops yields amongst all models during both phases. However, the correlation between mango canopy spread and intercrop yields shown negative trends. The yield reduction in intercrops varied from 37.0-52.6 % during first phase and 20.6-23.5 % during second phase of experimentation compared to sole crop. The results revealed that the fruit based AHM were effective in improving fruit yields of the mango. The mean maximum fruit yield of mango (7.02 t ha -1 ) was harvested with cowpea-toria crop rotation followed by black gram-toria (6.59 t ha -1 ) and minimum fruit yield (5.76 t ha -1 ) realized with sole mango tree during first phase (1999)(2000)(2001)(2002)(2003)(2004)(2005). Likewise, mean maximum fruit yield (13.71 t ha -1 ) from mango tree was obtained in the turmeric block followed by (13.00 t ha -1 ) in colocasia block and minimum fruit yield with sole mango tree (11.86 t ha -1 ). All the treatments of AHM recorded higher soil moisture as compared to sole mango plantation during both phases. The moisture retention under different AHM was in the order of cowpea (13.32 cm) [ black gram (13.29 cm) [ pigeon pea (13.27 cm) [ okra (12.42 cm) [ sesame (12.17 cm) [ sole mango (11.62 cm) during first phase, whereas moisture retention was observed in the order of turmeric (14.20 cm) [ colocasia (14.01 cm) [ sole mango (12.60 cm) during second phase. The cowpea-toria crop rotation with mango gave maximum benefit: cost ratio followed by okra-toria under rainfed conditions. Besides economic viability of cowpeatoria with mango, this system had improved tree growth as well as fruit yield of mango. In the second phase, mango ? turmeric yielded more benefit than mango ? colocasia system. In the first phase, the mango ? cowpea-toria system improved organic carbon, total nitrogen, phosphorus, potash and reduced pH by 49.0, 56.3, 48.6, 58.5 and 11.6 %, respectively as compared to initial values whereas mango ? turmeric system increased organic carbon, nitrogen, phosphorus, potash and reduction in pH by 51.0, 45.0, 29.7, 29.0 and 3.4 %, ...

Transforming Malta Orchard into Agroforestry System with Different Crops for Improving Productivity, Profitability and Land Uses

“…Besides, intercropping was not affected much due to less competition between under-storey and top-storey components for resources in the initial stage of malta orchard (Table 2). This study corroborated the findings of Rathore et al (2013), Dhakar et al (2013) and Saroj et al (2003). Nonetheless, malta plant might exerts some negative effects on crop growth by its dense roots, which could be the reason for low yields at the closest distance (Table 2) by the competition for below-ground resources (water and nutrient) between trees and crops (Wang et al, 2016;Zhang et al, 2017).…”

“…The mango (Mangifera indica L.) originated in northeastern India and Myanmar. It is known as the king fruit of Bangladesh because of its high adaptability in subtropical climates, large-scale production, high nutritive value, attractive appearance, marketing facility and popularity among growers and consumers (Matin et al 2008;Rathore et al 2013). The mango plant is a multipurpose fruit tree that yields fruit, timber, fuel etc.…”
