TL;DR: In this article, the authors compared corn-soybean intercrop in narrow strips with corn as monocrop in terms of dry matter (DM) yield and forage quality.
Abstract: Maize-soybean intercropping can increase forage quality with no detrimental effect on dry matter (DM) yield. The objective of this study was to compare corn-soybean intercrop in narrow strips with corn as monocrop in terms of DM yield and forage quality. This study was conducted in Matamoros, Coahuila (Mexico) in 2006 and 2007. Intercrops were established in rows spaced 0.50 m apart, evaluating alternate corn-soybean strips with one, two, three, and four rows per crop, and a treatment using an alternate twin-row planting pattern per crop, with a 1.0-m row-spacing. As control treatments, monocrops of corn in rows 0.76 m apart and soybean in rows 0.50 m apart were evaluated. A randomized complete block design with four replications was employed. Corn-soybean intercrop produced DM yields similar to those of monocropped corn due to higher corn yields in border rows adjacent to soybean. Crude protein (CP) yields per hectare in intercrop treatments were higher (27.5 to 42.8%) than those of monocropped corn, due to greater CP concentrations in intercrops (16 to 21 g kg ‐1 ). When soybean was harvested at the beginning maturity stage (R7), neutral detergent fiber concentration was reduced by 60 to 63 g kg ‐1 in corn-soybean intercropping compared to corn monocrop. Acid detergent fiber was not altered by intercropping. Results indicate that maize-soybean intercrop in narrow strips can provide forage quality advantages without affecting yield. Additional key words: chemical composition, dry matter and ear yields, dry matter partitioning, Glycine max, intraspecific competition, Zea mays.

TL;DR: In this article, an estudo foi avaliar o rendimento produtivo e o teor de proteina bruta no consorcio de milho e soja e milho em monocultura, em diferentes arranjos de linhas.
Abstract: A silagem e um dos principais ingredientes da alimentacao animal e estudos tem demonstrado que a adicao de biomassa de soja pode elevar o seu teor de proteina. O objetivo do estudo foi avaliar o rendimento produtivo e o teor de proteina bruta no consorcio de milho e soja e milho em monocultura, em diferentes arranjos de linhas. O delineamento utilizado foi de blocos ao acaso, com tres repeticoes e foram avaliados oito arranjos. Independente do arranjo de linhas, o estande de plantas de milho e soja nao sao influenciados, exceto o estante de soja que e estatisticamente superior no consorcio em relacao ao monocultivo de milho. Os arranjos consorciados exibiram diferencas na produtividade de biomassa de milho e soja para silagem em relacao ao monocultivo de milho, porem, ambos apresentam produtividade total de silagem semelhante. Independente do arranjo utilizado, os teores de proteina bruta sao semelhantes, entretanto ao ser cultivado de forma intercalada duas linhas de milho e duas de soja e quatro linhas de milho e quatro de soja com trinta cm entrelinha, observa-se maior produtividade de proteina bruta por area, em funcao da maior porcentagem de biomassa de soja e maior producao de massa seca do milho.

TL;DR: In this paper , the authors used a randomized block design with three treatments and three replications to find out the growth responses of maize and soybean crops cultivated by monoculture and intercropping planting systems and its carrying capacity for cattle feed.
Abstract: There had been a 2.145 ha fields transition in Bali which had a major impact on the loss of food production. However, there was raise in the population annually, therefore it disrupts local food security. Effort to raise the effectiveness and agricultural productivity areas through changing cropping system from monoculture to intercropping. This study aimed to find out the growth responses of maize and soybean crops cultivated by monoculture and intercropping planting systems and its carrying capacity for cattle feed. The study was arranged using a randomized block design with 3 treatments and 3 replications, namely: T1: Bima 20 URI VUB maize seeds in monoculture (40cm x 20cm x 80cm; 1 seed/hole or 70cm x 40cm x 100cm; 2 seeds/hole); T2: Anjasmoro, Deja 2 and Devon soybean VUB seeds in monoculture system (40cm x 20cm; 2-3 seeds/hole); T3: maize-soybean intercropping; Maize (2 rows; 40cm x 12.5; 2 seeds/hole); Soybeans (4 rows; 30cm x 10cm; 2-3 seeds/hole); both distance: 40cm. Data collected were growth performance, yield components and yield capacity of both maize and soybean crops also competition and profit value of maize and soybeans crops cultivated by intercropping planting system. The results showed that monoculture maize crops cultivated by monoculture planting system were better than it intercropped with soybean crops in terms of growth parameters. However, intercropping maize and soybean were produced greater yield components on cobs number, cobs and grains weight than monoculture (P<0.05), except grains weight per cobs. The monoculture soybean plant in growth, components and yield parameters were greater than intercropping (P>0.05). The ATER, LER, RCC, CR, and AYL values were 3.24; 1.28; -2.69; 4.58; -0.098 on maize and 2.52; 0.84; 1.82; 0.21; -0.158 on soybean. Those result was followed by carrying capacity in intercropping system by 30% usage can be used for 1.804 AU meanwhile 40% usage was sufficient for 1.353 AU. Intercropping system can be recommended to farmers to increase growth responses of maize-soybean and its potential carrying capacity for cattle feed.

TL;DR: Findings suggested that silage corn and forage soybean IC could be a viable approach to increase forage production with improved nutritional quality, enhanced the soil chemical or biological activities with better nutrient availability in the plant root zone following cultivation under cool climates in boreal ecosystem characteristic of Newfoundland and Labrador, Canada.
Abstract: Inadequate supply and inferior forage quality are major challenges facing Newfoundland and Labrador dairy industry. Therefore, dairy farmers have to depend on substantial forage imports from mainland. To overcome forage shortage, there is an increasing trend to add silage corn as a high biomass producing crop in existing forage production systems in the Province by using different nutrient management practices including the application of nutrient laden dairy manure (DM) or inorganic fertilizers (IF) for sustainable forage production. Therefore, I investigated the effects of silage corn and forage soybean cultivated as monocropping (MC) or intercropping (IC) on total forage production, forage nutritional quality, and soil health status. I further evaluated the effects of different DM and IF applications on the spatial distribution and quantification of essential nutrients in the root rhizospheres by employing a novel approach consisting of laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). Three forage soybean varieties (Big Fellow RR, Game Keeper RR, Kester’s Bob White Trailing Soybean) were IC with two silage corn genotypes (Yukon-R and DKC26‒28RIB) using a random complete block design (RCBD). Study results revealed that corn-soybean IC enhanced the agronomic performance, forage production and nutritional quality compared to MC. The land equivalent ratio surpassed 1, expressing IC had advantages over MC. IC reduced the RS-pH with a concomitant increase in RS-APase activity, that was affiliated with an increase in RS-Pavailable compared to corn and soybean MC. The soil active microbial community composition was also improved in IC systems compared to MC. Superior quality forage nutritional quality was observed in the IC treatment and included higher crude proteins, essential minerals, omega-3 and omega-6 fatty acids and reduced fiber contents compared to MC. Furthermore, LA-ICP-MS imaging revealed major variation in the spatial distribution of essential minerals in the soil A horizon, and quantitative differences in amounts of nutrients present in the root rhizospheres following different nutrient management practices. Collectively, these finding suggested that silage corn and forage soybean IC could be a viable approach to increase forage production with improved nutritional quality, enhanced the soil chemical or biological activities with better nutrient availability in the plant root zone following cultivation under cool climates in boreal ecosystem characteristic of Newfoundland and Labrador, Canada.

TL;DR: In this paper, an updated procedure for calculating reference and crop evapotranspiration from meteorological data and crop coefficients is presented, based on the FAO Penman-Monteith method.
Abstract: (First edition: 1998, this reprint: 2004). This publication presents an updated procedure for calculating reference and crop evapotranspiration from meteorological data and crop coefficients. The procedure, first presented in FAO Irrigation and Drainage Paper No. 24, Crop water requirements, in 1977, allows estimation of the amount of water used by a crop, taking into account the effect of the climate and the crop characteristics. The publication incorporates advances in research and more accurate procedures for determining crop water use as recommended by a panel of high-level experts organised by FAO in May 1990. The first part of the guidelines includes procedures for determining reference crop evapotranspiration according to the FAO Penman-Monteith method. These are followed by updated procedures for estimating the evapotranspiration of different crops for different growth stages and ecological conditions.
