Fuel and fodder from village woodlots: A Gujarat (India) experience

Having attained self-sufficiency in food production, India is now concentrating in using wastelands to increase its production of other products of agroforestry namely, fodder, fuel and small timber for the poorer section of society. Many agroforestry practices are being tried towards the attainment of this goal. In one such attempt, a 4 ha plantation was established in 1974 on Community grazing land in the village of Dhanori in Gujarat as a part of the State Village Forests Scheme. Casuarina equisetifolia was planted beca se it suited the site and because the villagers wished it. Grasses grew up naturally as a result of the enclosure. The trees were felled in 1983–4 and the distribution of benefits determined by the village panchayat. The internal Rate of Return was 35%. Villagers benefited from grasses, fuelwood and small timber for house construction and repair and from the employment generated. The success of the project led the village to organize itself into a Tree Grower's Society and undertake further planting in 1985–6. The demonstrated efficiency of the woodlot let to 200 ha of other plantations being established in the area. the poor benefited considerably from the project but if they had a greater say in the deliberations of the panchayat, the benefits could have been even greater. this agroforestry system has the potential of increasing the production of grasses, fuelwood, small timber and fruits (food) from wastelands.

Mechanical and cultural strategies to control Cirsium arvense in organic arable cropping systems

Infestation with Cirsium arvense in organic cropping is an increasing problem in many parts of Europe. Non‐chemical management strategies against C. arvense, based on cultivation tactics and/or different cutting regimes, have received very little attention for many years. This study presents results from four experiments, undertaken under organic growing conditions, on the effects of repeated mowing or hoeing during the first part of the growing season, used in combination with competition from a suppressive crop (grass/white clover mixture or red clover). The strategies were mainly aimed at diminishing the regenerative capacity of C. arvense and the effects were thus measured in the subsequent year in spring barley crops, in the absence of any weed control. In general, number of passes of mowing and hoeing linearly reduced the amount of aboveground C. arvense biomass in the subsequent year. Increased competition induced by the competitive crops further reduced C. arvense biomass. Differences in barley yield were explained by the amount of C. arvense biomass only in one experiment, where this weed was most abundant. Our results suggest that an acceptable level of C. arvense control can be achieved through an intensive hoeing or mowing campaign, within one growing season only. This may lead to increased crop yield in the subsequent year.

江苏地区禾本科冷季牧草生态适应性研究

引进美国冷季型禾本科牧草品种19个，在苏南（南京）和苏北（徐州）进行生态适应性试验。初步结果表明，多花黑麦草和杂交黑麦草产量较高，且集中于春季，尤其是四倍体品种鲜草产量最高。多年生黑麦草虽然产量也较高，但在苏南不能安全越夏。苇状羊茅和鸭茅在江苏能较好地越夏。
