SUMMARYA trial was carried out at Pantnagar in India during 1984–85 and 1985–86 to study the productivity of Egyptian clover and oats under intercropping. Cross sowing of both the crops either at full or half seed rates and line sowing of oats in broadcast Egyptian clover was better than other intercropping systems or sole cropping in respect of herbage production, digestible dry matter yield and land equivalent ratio but crude protein yield from the mixed crops was similar to that from sole cropped Egyptian clover.

To characterise the urban livestock keeping practices and constraints in Kisumu municipality, Kenya, a questionnaire survey was carried out. Thirty-four contact farmers were interviewed on general farm characteristics and production constraints. The farming activities were categorised as either livestock only (41 %), or mixed crops and livestock (59 %). The surveyed farmers kept mainly cattle (100 %), chickens (82 %) and goats (74 %). Most (94 %)of the farmers had kept livestock for prolonged periods mainly for income generation (97 %) and domestic consumption (59 %). These data show that livestock keeping was popular and could be harnessed to increase food security, although the farmers kept mainly low-producing indigenous cattle (98 %) which were grazed on unutilised land. The main production constraints mentioned by farmers included diseases (100 %), poor fertility (68 %) and lack of feed (56 %). The diseases varied with species of ruminants and included lumpy skin disease (71 %), diarrhoea (65 %) and helminthosis (62 %). The source of advice on management and treatment of the livestock was almost equally from private and government veterinary personnel. To improve livestock productivity, it is recommended that key stakeholders address the constraints mentioned in this study and in particular that the occurrence of diseases should be investigated with a view to developing sustainable control strategies.

The object of the research is to study the influence of the method of growing mown and grain-forage varieties of spring vetch in mixed crops with spring rapeseed on the seed yield and crop structure. Indicators that characterize productivity, intensity of arable land use, competitiveness and aggressiveness of crops are considered. Sowing spring vetch with a seeding rate of 1.3, 0.8, 0.6 and 0.4 million germinating seeds per hectare mixed with rapeseed leads to the formation of a grain crop that significantly exceeds the yield for single-species vetch sowing. Evaluation of Land Equivalent Ratio (LER) shows that when using vetch-rapeseed crops, the productivity of 1 ha of arable land increases from 1.38 to 1.98 times, while both the influence of varietal specificity and the seeding rate of the legume component is manifested. The efficiency of arable land use increases due to the interaction of both crops and increasing their competitiveness in the agrocenosis. In the conditions of the Middle Urals, high efficiency of vetch cultivation in mixed crops with rapeseed was revealed, and the influence of changes in the seeding rate on the yield of spring vetch seeds was established.

Nitrogen consumption is one of the most important factors and necessary conditions for plant growth and development. The contribution from the biological fixation of N2 by legumes in grass mixtures can reduce or completely replace the need for industrial nitrogen fertilizers for perennial bluegrass grasses. When white clover is cultivated in grass mixtures, the net nitrogen gain to the ecosystem from the atmosphere during the growing season as a result of biological fixation can vary from 100 to 300 kg/ha or more. This is equivalent in effect to the application of mineral nitrogen fertilizers on grass in doses from 150 to 350 kg/ha. Types and varieties of perennial grasses have different competitiveness and complementarity when they are jointly cultivated in mixed crops. The use of grasses to create less lying grass stands allows you to increase the collection of white clover seeds. When cultivating white clover in grass mixtures, there was a decrease in the biological yield of seeds compared to mono-crop by 15–38% due to a decrease in the number of generative shoots. However, seed losses during harvesting decreased by up to 9–23% depending on the type of accompanying cereal crop and the method of harvesting. They were minimal in mixed crops of clover with pasture ryegrass or reed fescue and accounted for 9–11% and 12–13% of the biological yield of seeds, respectively. The highest seed collections were obtained from grass stands of the second year of use without the use of nitrogen fertilizers from crops of pasture ryegrass, reed fescue and meadow fescue: 761, 402 and 373 kg/ha, respectively. Along with the types of cereal components, the nature of plant interaction in grass mixtures and their response to anthropogenic stresses also depend on the genotypes of white clover varieties. A comparative assessment of the effectiveness of cultivating clover varieties mixed with reed fescue showed that the highest collection of legume seeds 188 kg/ha from grass stands of the first year of use was provided by the 'Lugovik' variety – 36–68% more than with grass mixtures of the cv. 'Volat' variety f. giganteum and cv. 'VIK 70' of the f. hollandicum variety.

Greenhouse is widely applied to provide protection against pest and harsh environment condition and most farmers usually planted mixed crops inside. However, this system creates an isolation to pollination which responsible for fruit production. In this study, local domesticated stingless bees, Trigona (Tetragonula) laeviceps, was applied as pollinator for two crops, beans (Phaseolus vulgaris L.) and tomatoes (Solanum lycopersicum L.) planted as mixed crops inside greenhouse. The benefit of the bees was measured as pollination success and quality of the crops produced (size and weight). Tomato flowers received no visit from both wild pollinators (all was Apis cerana) and stingless bees while in bean flowers, A. cerana exhibited more and longer visits to flower than T. laeviceps albeit lower number of flowers visited. The pollination efficiency between wild pollinator and T. laeviceps for beans (both at 41%) while self pollination produced better pollination efficiency for tomatoes planted at open field (84% compared to 71%). Beans planted at open field produced better products (bigger size and heavier) while tomatoes produced lesser quality although the differences were not significant. Based on this study, T. laeviceps may applied as pollinator agent in greenhouse and for mixed crops of beans and tomatoes.
