Background: Non-edible oil as biodiesel helps to meet the energy demand and to reduce environmental degradation. Jatropha curcas is one of the potential oil yielding plant which can be grown under agroforestry systems without affecting food production. Hence the current study aimed to find out compatible intercrop under J. curcas and optimum spacing of J. curcas for intercropping. Methods: A study was carried out in three and a half-year old J. curcas plantation. Different spacings of J. curcas viz., 3m × 3m, 4m × 2m and 4m × 3m and different legumes viz., blackgram, greengram, cowpea, groundnut and oilseed crops viz., gingelly and sunflower were evaluated in split plot design. Result: Growth and yield of intercrops, available soil N, P and uptake of N, P, K by intercrops were significantly higher at wider spacing of J. curcas (4m × 3m). Among the intercrops, groundnut recorded higher uptake of N (67.3 kg ha-1), P (19.9 kg ha-1) and K (65.3 kg ha-1). Groundnut produced a significantly higher yield (885 kg ha-1) followed by cowpea (630 kg ha-1). The study found that planting of J. curcas at 4m × 3m spacing and intercropping with groundnut is a compatible and profitable J. curcas based agroforestry system.

Allelopathic Effects

ABSTRACT Selection of tree species under agroforestry systems is crucial to sustain the productivity of a crop. In present study, allelopathic effects of the leaf litters of 5 trees named Rose wood (Dalbergia sissoo), Guava (Pisidium guajava), Eucalyptus (Eucalyptus camaldulensis), Sacred fig (Ficus religiosa) and Jaman (Syzygium cumini) species on wheat growth and yield was examined. Leaf litter of each tress species was mixed in soil with two doses @ 100 and 200 g of leaves of each species per pot. Higher shoot length, shoot dry weight, number of spikelets per spike and biological yield were recorded in 200 g sun dried Jaman (Syzygium cumini) leaves. Total number of tillers per plant and number of ears per plant were higher under the application of Eucalyptus camaldulensis leaves (200 g sun dried) as compared to other treatments. Spike length, grain yield per pot, number of grains per pot and harvest index were maximum in 200 g sun-dried Sacred fig (Ficu sreligiosa) leaves. Majority of the parameters were promoted at lower doses of leaves per pot, however, at higher doses they started inhibiting the growth and grain yield of wheat.

Field experiment was conducted at farmer’s field in Coimbatore District of Tamil Nadu with two different soil sulphur status i.e., soil with sufficient and deficient levels of sulphur status in order to study the response of graded doses of sulphur on two different sesamum varieties. The experiment was laid out in split plot design with two factors viz., Two sesamum varieties (TMV 7 - Black var., SVPR 1 - White var.) and Six sulphur levels (0, 20, 30, 40, 50, 60 kg S ha-1). Application of 30 and 50 kg S ha-1 at sulphur sufficient and sulphur deficient soils has increased the plant height at VS and FS, at harvest the highest plant height was recorded. Whereas, other important traits like number of branches per plant, number of capsules per plant, length of capsule and dry matter accumulation has registered the highest response for sulphur application at 30 kg ha-1 which was on par with higher doses in sulphur sufficient soil and in case of deficient soil significant response was observed till 50 kg S ha-1. Among the two varieties, TMV 7 has performed better when compared with SVPR 1.

The effects of pruning of Paraserianthes falcataria tree in an agroforestry system on yield of intercrops and tree performance were studied at Perhutani RPH Jatirejo, BKPH Pare, KPJH Kediri. Maize, stick nut, and chili were used as companion crops in between rows of two years old Paraserianthes falcataria tree. A split plot design with four replicates was set up for the experiment. The trees were 25%, 50% and 75% pruned. The measured parameters included growth and yield of the intercrops and performance of the tree. Results of this study showed that regular pruning of the agroforestry tree and planting of intercrops did not hinder growth and performance of the agroforestry tree, especially that was pruned 75%. Pruning of the tree also increase yield of the intercrops

This study was aimed to detect the effect of various treatment periods of weedy on the growth and yield of soybean; and to determine the most appropriate time periods of weedy for soybean in agroforestry systems with kayu putih. The experiment had been conducted in Menggoran, BDH Playen, KPH Yogyakarta, Gunungkidul Regency, Special Province of Yogyakarta from February 28 to May 9, 2015. Randomized Complete Block Design (RCBD) with three blocks as replications waas applied  in this experiment. The treatments were weedy periods on 0, 14, 28, 42, and 56 days after planting (dap) and weed-free period on 0, 14, 28, 42, and 56 dap. The results showed that there were significant differences in the soil moisture content, root surface area, root length, chlorophyll content, root dry weight, shoot dry weight, dry weight of soybean seeds, and weed dry weight. The highest seed weight per hectare was found in weed-free until harvest treatment but it was not significantly different from weedy periods after 56 dap and weed-free after 14 dap. The effective periods of weedy time for soybean in agroforestry systems with kayu putih began at 28 dap - 56 dap.

Assessment Procedure

In the context of energy security, rural development and climate change, India actively promotes the cultivation ofJatropha curcas, a biodiesel feedstock which has been identified as suitable for achieving the Indian target of 20% biofuel blending by 2017. In this paper, we present results concerning the range of environmental impacts of differentJatropha curcascultivation systems. Moreover, nine agronomic trials in Andhra Pradesh are analysed, in which the yield was measured as a function of different inputs such as water, fertilizer, pesticides, and arbuscular mycorrhizal fungi. Further, the environmental impact of the wholeJatropha curcasbiodiesel value chain is benchmarked with fossil diesel, following the ISO 14040/44 life cycle assessment procedure. Overall, this study shows that the use ofJatropha curcasbiodiesel generally reduces the global warming potential and the nonrenewable energy demand as compared to fossil diesel. On the other hand, the environmental impacts on acidification, ecotoxicity, eutrophication, and water depletion all showed increases. Key for reducing the environmental impact ofJatropha curcasbiodiesel is the resource efficiency during crop cultivation (especially mineral fertilizer application) and the optimal site selection of theJatropha curcasplantations.

Abstract. Agroforestry is an increasingly popular farming system enabling agricultural diversification and providing several ecosystem services. In agroforestry systems, soil organic carbon (SOC) stocks are generally increased, but it is difficult to disentangle the different factors responsible for this storage. Organic carbon (OC) inputs to the soil may be larger, but SOC decomposition rates may be modified owing to microclimate, physical protection, or priming effect from roots, especially at depth. We used an 18-year-old silvoarable system associating hybrid walnut trees (Juglans regia × nigra) and durum wheat (Triticum turgidum L. subsp. durum), and an adjacent agricultural control plot to quantify all OC inputs to the soil – leaf litter, tree fine root senescence, crop residues, and tree row herbaceous vegetation –, and measure SOC stocks down 2 m depth at varying distances from the trees. We then proposed a model that simulates SOC dynamics in agroforestry accounting for both the whole soil profile and the lateral spatial heterogeneity. OC inputs to soil were increased by about 40 % (+1.11 t C ha−1 yr−1) down to 2 m depth in the agroforestry plot compared to the control, resulting in an additional SOC stock of 6.3 t C ha−1 down to 1 m depth. The model described properly the measured SOC stocks and distribution with depth. It showed that the increased inputs of fresh biomass to soil explained the observed additional SOC storage in the agroforestry plot. Moreover, modeling revealed a strong priming effect that would reduce the potential SOC storage due to higher organic inputs in the agroforestry system by 75 to 90 %. This result questions the potential of soils to store large amounts of carbon, especially at depth. Deep-rooted trees modify OC inputs to soil, a process that deserves further studies given its potential effects on SOC dynamics.

The experiment was conducted to determine the effect of irrigations and sowing dates on growth and yield performance of wheat in the experimental field of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period of November 18, 2012 to March 30, 2013. The experiment was comprised of two factors, viz. factor A: two irrigations namely irrigation (I) and no irrigation i.e. control (I0), and factor B: three sowing dates such as S1: 1st sowing on 18 November, S2: 2nd sowing on 03 December and S3: 3rd sowing on 18 December. The experiment was laid out in a split plot design with three replications. Irrigation was assigned in the main plot, while sowing time was in the sub-plots. Data on grain yield and different yield contributing characters were taken after harvest. Results indicated that the highest grain yield was obtained with I (2.915 t ha-1) and S1 (2.983 t ha-1). The interaction of irrigation (I) and sowing on 18 November (S1) showed the maximum yield (3.387t ha-1), spike length (17.08 cm), 1000 grain weight (43.4 g), spikelets spike-1 (20.03) and grain spike-1 (65.58) of wheat.The Agriculturists 2016; 14(2) 77-85
