Cultivar Mixture

Growing two or more cultivars of same crop species in mixture reduces intra-specific competition for natural resources and increases competitive ability of crops against weeds and thus enhances crop yield. The objective of this study was to evaluate the potentiality of growing rice cultivars in mixtures for minimizing weed pressure and increasing rice yield. The experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during Aman season (July-December) 2017. Two transplant Aman rice cultivars viz. Binadhan-13 (tall, late- maturing and fine grain aromatic cultivar) and BRRI dhan49 (semi-dwarf, mid-maturing and coarse grain cultivar) were grown following two spatial arrangements viz., alternate row and alternate hill, and nine different cultivar mixture (Binadhan-13:BRRI dhan49) row ratios viz., 1:0, 1:2, 2:1, 2:3, 3:2, 2:4, 4:2,1:1 and 0:1. The experiment was laid out in a randomized complete block design (RCBD) with three replications. Results confirmed the positive influence of spatial arrangement and cultivar mixture ratio on rice productivity. Both the cultivars showed better growth and higher yield when grown in mixture irrespective of ratios compared to their sole culture performances. But cultivar mixture ratio showed no advantages over sole culture in suppressing weeds. Based on the total yield Binadhan-13 and BRRI dhan49 inter-planted in 1:1 row ratio following alternate hill performed the best resulting in 50% and 12% yield advantages over sole culture of Binadhan-13 and BRRI dhan49, respectively. Therefore, growing tall and dwarf rice cultivars in mixture can be adopted as a tool for increasing rice productivity. J. Bangladesh Agril. Univ. 17(2): 133–141, June 2019

SUMMARYThe yield potential of a highly productive non-commercial Type IV bean cultivar was determined under optimum field conditions, grown in monoculture at 1 plant/m2 on trellises 3 m high. Canopy growth was analysed by dividing the stand into 25 cm horizontal strata. The main components of yield were number of inflorescences and number of pods per stratum. Daily yield for the growing period was 4.9 g dry weight/m2. Although a high yield per plant was recorded (823 g/plant) drop of young pods and seed abortion were the major factors reducing the potential yield.

Management Approaches

Rice is a principal source of food for more than half of the world population, and more than 90% of rice worldwide is grown and consumed in Asia. A change in establishment method from manual transplanting of rice seedlings to dry-seeded rice (DSR) has occurred in some countries as growers respond to increased costs or decreased availability of labor or water. However, weeds are a major constraint to DSR production because of the absence of the size differential between the crop and the weeds and the suppressive effect of standing water on weed growth at crop establishment. Herbicides are used to control weeds in DSR, but because of concerns about the evolution of herbicide resistance and a scarcity of new and effective herbicides, there is a need to integrate other weed management strategies with herbicide use. In addition, because of the variability in the growth habit of weeds, any single method of weed control cannot provide effective and season-long control in DSR. Various weed management approaches need to be integrated to achieve effective, sustainable, and long-term weed control in DSR. These approaches may include tillage systems; the use of crop residue; the use of weed-competitive cultivars with high-yield potential; appropriate water depth and duration; appropriate agronomic practices, such as row spacing and seeding rates; manual or mechanical weeding; and appropriate herbicide timing, rotation, and combination. This article aims to provide a logical perspective of what can be done to improve weed management strategies in DSR.

Vegetative Development

Several factors influence in the vegetative development, yield and quality of pineapple fruits, among which the cultural treatments adopted throughout the production cycle stand out, mainly weed control, mineral nutrition, irrigation and induction artificial flowering. The purpose of this review was to present the main advances in research on cultural treatments in the cultivation of pineapple (Ananas comosus L. Merril) and their effects on yield and fruit quality. Current research shows that interventions for weed management, through chemical control with herbicides or the adoption of organic or inorganic soil cover are strategies that can be adopted by producers who seek to reduce labor costs and provide good conditions for plant development. The use of mulching is a promising and effective practice, given the cost reduction with polluting herbicide applications and improvement of the physicochemical quality of the soil. Regarding mineral nutrition, pineapple is a rustic plant, tolerant to soils with moderate acidity and low levels of nutrients in the soil, however, liming and fertilization are essential for crops where high yields are sought. In the same way, it is verified that the pineapple, even being a CAM metabolism plant, tolerant to situations of water stress, is highly responsive to irrigation, which provides improvements in the vegetative and reproductive development of the plant. Another essential management practice in pineapple crops is artificial floral induction, a practice that aims to synchronize the flowering period, facilitate harvesting and ensure a consumer market in times when the supply of fruit is scarce

The Difference

The yield gap discussed in this paper is the difference between the potential farm yield and the actual average farm yield of rice is 1.92 t ha-1 in Bangladesh. The yield gap is mainly caused by physical, biophysical, socioeconomic and institutional factors. Different strategies, such as integrated crop management (improve adapted varieties, site specific nutrient management, locally adapted integrated weed management and optimized water management) practices, timely supply of inputs including credit to farmers, research and extension collaboration to transfer the new technologies have been discussed to minimize yield gap. Suggestions have been made to make credit available to resourcepoor small farmers to buy necessary inputs, reducing transaction cost, simplifying lending procedures and strengthening monitoring mechanism of the current credit system are, however, essential to enable the farmers to avail the credit facility. Efforts should be made to update farmers’ knowledge on the causes of yield gaps in crops and measures to narrow the gaps through training, demonstrations, field visits and monitoring by extension agencies to achieve high yield. Based on present yield gap of rice (1.92 t ha-1) at least Tk. 556 billion could be earned from the additional production annually by narrowing 40 % the yield gap. SAARC J. Agri., 18(2): 167-180 (2020)
