<p>Field experiment was conducted during the rainy seasons of 2011 and 2012 at the Teaching and Research Farm of the Faculty of Agriculture, Nasarawa State University, Keffi-Lafia Campus to study the competitive behaviour of groundnut in Sesame-groundnut intercropping system. The experiment consisted of four rates of poultry manure (0, 3.0, 6.0 and 9 t ha<sup>-1</sup>) and two planting arrangement (single alternate row and double alternate row planting arrangement). The eight treatment combinations were laid out in a randomized complete block design with four replications. The results obtained in both the years showed that sesame when grown with groundnut under different rates of poultry manure and planting arrangement appeared to be a dominant crop as indicated by its higher values of Land equivalent ratio, competitive ratio, higher and positive values for aggressivity and area time equivalent ratio. Application of 6 t ha<sup>-1</sup> of poultry manure and double alternate row planting arrangement produced the highest values for all the competition indices measured respectively.</p>

A field experiment was conducted from August to November, during the 2012 and 2013 cropping seasons at the Research Farm, University of Agriculture, Makurdi, Nigeria, to identify the optimum plant density of okra and intercropping effects on yields of egusi melon-okra mixture and to assess the yield advantages of the intercropping system. The experiment was a 3x3 split plot arrangement of treatments, fitted in a randomized complete block design (RCBD), replicated four times. The intercropping (sole egusi melon, sole okra and egusi melon-okra mixture) constituted the main plots, while the population densities of okra (33,000, 40,000 and 50,000 plants ha-1 equivalent) into egusi melon were allocated to the subplots. Results of study showed that to maximize intercrop yield of okra in an egusi melon-okra intercrop, the optimal population density of okra is 33,000 plants ha-1, while that of 40,000 plants ha-1 is optimal to maximize intercrop yield of egusi melon. Intercropping egusi melon and okra significantly (P≤0.05) reduced yields of egusi melon (37.5 % and 40.5 % respectively, in years 2012 and 2013) and that of okra (9.7 % and 16.9 % respectively, in years 2012 and 2013). The highest mean land equivalent ratio value of 1.57 and highest land equivalent coefficient values of 0.60 and 0.63 respectively, in years 2012 and 2013, were recorded for okra sown into egusi melon at the population density of 40,000 plants ha-1. It is most advantageous having both crops in intercrop when okra is sown into egusi melon at the population density of 40,000 plants ha-1. This should therefore be recommended for Makurdi location, Nigeria.

A field experiment was conducted from August to November, during the 2012 and 2013 cropping seasons at the Research Farm, University of Agriculture, Makurdi, Nigeria, to evaluate the yield effects of egusi melon-okra intercrop as influenced by the interaction of time of introducing okra x cropping systems, and to assess the yield advantages of the intercropping system. The experiment was a 3x3 split plot arrangement of treatments, fitted in a randomized complete block design (RCBD), replicated four times. The cropping systems (sole egusi melon, sole okra and egusi melon-okra mixture) constituted the main plots, while the time of introducing okra (mid August, late August and early September) into egusi melon were allocated to the subplots. Results of study showed that to obtain optimal intercrop yield of okra in an egusi melon-okra intercrop, it is appropriate planting okra at the same time with egusi melon in mid August, while introducing okra into egusi melon in late August is appropriate to obtain optimal intercrop yield of egusi melon. Intercropping egusi melon and okra significantly (P≤0.05) reduced yields of egusi melon (37.5 % and 40.5 % respectively, in years 2012 and 2013) and that of okra (9.7 % and 16.9 % respectively, in years 2012 and 2013). The highest mean land equivalent ratio value of 1.57 and highest land equivalent coefficient values of 0.53 and 0.70 were respectively recorded, in years 2012 and 2013, for okra introduced into egusi melon in early September. These recommendations are appropriate for Makurdi location, Nigeria

Alternate planting combinations of maize (Zea mays L.) with lima bean (Phaseolus lunatus L.) using wood ash as soil amendments were compared with the sole planting of each crop during the late 2014  and early 2015 planting seasons at the Teaching and Research Farm of the Federal University of Technology, Akure. The experiment in each season adopted three patterns of intercropping using ash as a soil amendment and laid out in a Randomized Complete Block Design (RCBD) with three replications. The experiment comprised 10 treatments: Sole planting of maize amended, sole planting of maize unamended, sole planting of lima beans amended and sole planting of lima beans unamended. Others were; 75:25 maize-lima beans amended, 75:25 maize-lima beans unamended, 50:50 maize-lima beans amended, 50:50 maize-lima beans unamended, 25:75 maize-lima beans amended and 25:75 maize-lima beans unamended. Wood ash was applied two weeks after planting at the rate of 2.4 kg (4 tons per hectare) to each plot. The combined yield advantage in terms of land equivalent ratio (LER) indices was greatest (1.95) in the case of 3 rows of maize and 1row of lima beans intercropping arrangements. Competition indices (CR) for all crops in all intercropping arrangements were more than 0.1 indicating that both crops were equally competitive.  However, crop aggressivity (A) showed that maize was more dominant than lima beans due to plant population. Costs and returns analysis revealed that maize and lima beans intercropping at all proportions were more profitable than their corresponding monocrops.

Order to study the effect of density, the control weed and various proportion corn (704 Variety) and peanut (Goli Variety) intercropping an experiment was conducted in 2012 in Research station of agriculture, University of Zabol. The experiment design was factorial in randomized complete block design with three replications. Experiment factors consisted of planting proportions in 4 levels (sole crop of corn, 50% corn + 50% peanut, 100% corn + 100% peanut and sole crop of peanut), control weed in 3 levels (non-weeding, once-weeding and twice-weeding) and the space between rows in 2 level (40 and 50 cm) has been considered. The evaluated Characteristics in environmental sources are (Photosynthetic Active Radiation, Temperature and soil Moisture), the nutrients of soil include (N, K, Na, Mg, Ca, and C) and to evaluate intercropping of pure was used land equivalent ratio and economical yield. All Characteristics of study were affected by planting system.There was significant interaction between planting system, weeding and density in the absorption of light, temperature and moisture of soil. The results showed that photosynthesis active radiation absorbed by the intercropping was higher than sole crop in both plants. The results showed that changes in soil nutrient capacity of single elements (Na and K) in the treatment of mixed and monoculture peanut was more than monoculture corn and divalent elements (Ca and Mg) in mixed and monoculture corn more than mixed replacement and peanut monoculture. The highest land equivalent ratio (1.048) was accounted additive intercropping. Generally the mixed cultures with increasing density and control weed caused increase soil fertility and amount of soil nutrients after harvest. Treatment 100% Corn +100% peanut was the best treatment because using sources and increasing soil fertility and crop yield in comparison to sole crop.

The work was carried out at UNESP, Jaboticabal, São Paulo State, Brazil, from September to December 2006, to evaluate the effect of nitrogen fertilization on intercropping of lettuce and rocket. The experiment was conducted in a randomized complete block design, with four replications, treatments being arranged in a 4 x 4 + 2 factorial design. The treatments were the result of a combination of four N rates for lettuce (0, 65, 130 and 195 kg ha-1) and four N rates for rocket (0, 65, 130 and 195 kg ha-1), plus two additional treatments, which corresponded to lettuce and rocket under single cropping. Veronica (lettuce) and Folha Larga (rocket) were the cultivars used. An increase in the N rate for both cultures, under intercropping system, caused fresh matter gains and higher yields for lettuce and rocket, maximizing the land equivalent ratio (1.84) at 127 kg ha-1 of N for lettuce and 195 kg ha-1 of N for rocket.

Culture Development

Vegetable development and productivity are influenced by several factors, including the nutrient amounts available. Providing adequate nitrogen favours vegetative growth and promotes increased productivity, in addition to providing greater succulence and improving leaf quality. This work evaluated the effect of nitrogen doses and sources on arugula culture development and productivity. The experiment was conducted on the experimental farm at the State University of Goi&aacute;s, Ipameri campus, in the municipality of Ipameri, Goi&aacute;s state (GO). The experiment used a 2 &times; 5 factorial randomized complete block design, with two sources (normal urea and coated urea), five nitrogen doses (0, 60, 120, 180 and 240 kg ha-1 of N) and four replicates. Plant height, stem diameter, leaf number, fresh shoot matter, dry shoot matter and productivity were evaluated. The results obtained here suggest that nitrogen sources do not influence arugula culture development, but nitrogen doses influence the arugula culture&rsquo;s productive characteristics.

A field experiment is conducted to study the effect of different levels of peat (0, 25, 50, 75, and 100 Mg ha-1 to uncropped and cropped soil to wheat. Soil samples are taken in different period of time (0, 3, 30, 60, 90, 120, and 180 days after cultivation to determine (NaHCO3-Exteractable P at 3 different depths (0-10, 10-20, and 20-30 cm). Field Experiment is conducted in a randomized complete block design (RCBD) with four replicates. Wheat, Al-Rasheed variety, is cultivated as a testing crop. The entire field is equally dived in two divisions. One of the two divisions is cultivated to wheat and the second is left uncropped. The effect of five levels of peat namely 0, 25, 50, 75, 100 Mg ha-1 is investigated. Soils are fully analyzed to determine its physical and chemical characteristics. The soil samples are collected after 3, 30, 60, 90, 120, and 180 days for determining essential parameters and indicators that reflect the effect of the level of peat applications. Sodium bicarbonate - extractable P in uncropped and cropped soils at all depths, markedly decreases with time after peat application which has been attributed to plant uptake and rapid reaction of P with soil constituents. Sodium bicarbonate - extractable P with time in soil receiving 50 Mg ha-1 in both uncropped and cropped soil linearly decreases with the time of cultivation

Soybean (Glycine max L. Meril) is one of the most important and well recognized oil seed and grain legume crops of the world. A field experiment was conducted to investigate the efficacy of BAU-Biofungicide (Trichoderma harzianum), Trichoderma based IPM Lab bio-pesticide and Bavistin against anthracnose of soybean. Five soybean cultivars viz. Sohag, BARI Soybean-6, BINA Soybean-1, BINA Soybean-2 and BINA Soybean-3 were used in this experiment. The field experiment was carried out following Randomized Complete Block Design in the field laboratory of the Department of Plant Pathology, Bangladesh Agricultural University, Mymensingh. Anthracnose infections were found initially lower at 80 DAS, moderate infections were found at 95 DAS and the highest infections were recorded at 110 DAS in case of all the tested five soybean varieties. The highest percent reduction of anthracnose infected plants/plot over control was observed in Bavistin treated plot (76.25%) that was near to BAU Biofungicide treated plots. All the growth parameters of soybean plants such as plant height, number of pods/plant, seed weight/plant, yield/plot and yield/ha were increased significantly in BAU-Biofungicide treated plots that showed best performance in compare to IPM Lab bio-pesticide (2%) and Bavistin @ 0.2% when these treatments were applied two times with 15 days interval. However, anthracnose incidence was reduced significantly when all the treatments applied in this experiment and the effect of BAU-Biofungicide was found almost similar to Bavistin in reduction of anthracnose of soybean.Res. Agric., Livest. Fish.2(3): 419-426, December 2015
