“…In most of the crops the number of leaves (branches)/ plant was relatively higher in open condition than under tree canopy because of availability of more light. The results are in line with the findings of rice and mungbean intercropped with A. mangium, A. auriculiformis and Gliricidia sepium (Miah et al (1997) and wheat varieties were raised in agrisilvicultural system (Puri et al (2001 (Dhyani and Chauhan, 1989), ginger raised under coconut (Jayachandran et al, 1991) and ginger and turmeric grown under poplar (Jasural et al, 1993 (George and Nair, 1987), three wheat varieties grown under Populus deltoides (Singh et al, 1993), Cicer arietinum, Brassica juncea and Dolichos lablab intercropped with C. equisetifolia, Adina cordifolia and Gmelina arborea (Maheta et al, 1996), Prosopis cineraria with Cassia angustifolia (Vyas, 2001), D. sissoo with sesamum (Naugraiya and Jhapatsingh, 2005) and C. equisetifolia, E. hybrid, D. sissoo and Tectona grandis with ragi, sesamum, black gram and cowpea (Mohanty et al, 2008).

“…In most of the studies, localised varieties were grown under poplar at the recommended date of sowing such as Inqalab-91 in Faisalabad (Chaudhry et al 2003);PBW-226, WH-542, HD-2329, PBW-154 andPBW-299 in Punjab (Pannu andDhillon 1999); HS-295, Sonalika, HD-2285 and HD-2380 in Himachal Pradesh (Chauhan and Dhiman 2007); HUW-234 in Bihar; HD-2285 in Uttar Pradesh (Sharma et al 2001) and Sujata, Lok-1, Kanchan and GW-174 in Chhattisgarh (Puri et al 2001). In most of these studies, the wheat varieties were evaluated based on their one year performance (Singh et al 1993;Pannu and Dhillon 1999) or conclusions were drawn based on survey and discussions with farmers (Kumar et al 2004;Jain and Singh 2000). Competition for below and above ground resources often changes with the increase in tree age.…”

Productivity and nutrient uptake of newly released wheat varieties at different sowing times under poplar plantation in north-western India

Standardisation of cultural practises is one of the primary objectives to make the system ecologically sustainable and economically viable. In this context, the present study was conducted to optimise the time of sowing in relation to newly released wheat varieties under 4-6 year old poplar block plantation. Six widely grown wheat varieties (PBW 502, PBW 343, WH 542, PDW 274, PBW 509 and PBW 373) were intercultivated during three consecutive crop growth seasons at three times of sowing (mid November, late November and mid December) under block plantation of poplar (Populus deltoides Bartr.) clone G-48. The grain yield and nutrient uptake of wheat varieties was higher in open conditions than under the trees. The wheat variety PBW 502 out yielded the rest of wheat varieties over different sowing times. The highest grain yield was recorded when crop was sown during mid November over the 3 years. Thus adoption of PBW 502 under poplar plantation would substantially improve the overall productivity of the system without any additional input cost. All the varieties performed better when sown early compared to one-month delay. The various growth parameters like tiller height and number, spike length and 100 grain weight contributed significantly towards higher grain yield in early sown conditions (mid November) under poplar irrespective of its age of plantation. The nutrient uptake (N, P and K) by wheat straw and grain was higher in early sown crop with longer growth span than the late sown crop. The higher quantity of N, P and K was removed from soil by PBW 509, PBW 373 and PBW 343, respectively.

Unveiling Undercover Cropland Inside Forests Using Landscape Variables: A Supplement to Remote Sensing Image Classification

et al. 2015

The worldwide demand for food has been increasing due to the rapidly growing global population, and agricultural lands have increased in extent to produce more food crops. The pattern of cropland varies among different regions depending on the traditional knowledge of farmers and availability of uncultivated land. Satellite images can be used to map cropland in open areas but have limitations for detecting undergrowth inside forests. Classification results are often biased and need to be supplemented with field observations. Undercover cropland inside forests in the Bale Mountains of Ethiopia was assessed using field observed percentage cover of land use/land cover classes, and topographic and location parameters. The most influential factors were identified using Boosted Regression Trees and used to map undercover cropland area. Elevation, slope, easterly aspect, distance to settlements, and distance to national park were found to be the most influential factors determining undercover cropland area. When there is very high demand for growing food crops, constrained under restricted rights for clearing forest, cultivation could take place within forests as an undercover. Further research on the impact of undercover cropland on ecosystem services and challenges in sustainable management is thus essential.
