Effect of Crop Establishment Method and Nutrient Management on Yield and Yield Attributes of Short Duration T. Aman Rice

Abstract

A field trial was conducted at Agronomy Farm of Bangladesh Rice Research Institute to find out the effect of crop establishment method and nutrient management on yield performance of BRRI developed short-duration Aman rice var. BRRI dhan62 during July to October 2016. The trial comprised of four crop establishment methods viz., M1 = BRRI recommended puddle transplanting, M2 = System of rice intensification (SRI) method (9-days old seedling transplantation), M3 = Sprouted seed in line sowing and M4 = Sprouted seed in broadcasting and three nutrient management levels viz.,N1 = BRRI recommended nutrient management, N2 = Soil test-based nutrient management, N3 = Control. The study was conducted in a factorial Randomized Complete Block Design with three replications. The result showed that planting methods had significant effects on the yield of rice. The SRI method along with BRRI recommended fertilizer dose produced the maximum grain yield of 4.49 t ha-1 which was statistically similar with that produced in SRI method day- and soil test-based nutrient management combination. The highest gross margin (Tk. 36,308.00 ha-1) and cost benefit ratio (2.06) were observed in direct seeding of sprouted seed in line sowing method along with BRRI recommended fertilizer dose. So, direct seeding of sprouted seed in line could be a suitable planting method due to reduction of 26.0% production cost associated with seedling raising and transplanting operations.

Conservation tillage and fertiliser management strategies impact on basmati rice (Oryza sativa L): crop performance, crop water productivity, nutrient uptake and fertility status of the soil under rice-wheat cropping system

“…CETs vary in resource consumption, energy needs, and climate change mitigation, which can affect farmers’ produce, income, and environmental health. One of them, India, transplants seedlings into puddle soil by hand ( Nahar et al, 2017 ). Continuous conventional puddled rice transplanting diminishes water and land productivity, degrades soil structure, and lowers subsurface water levels.…”

“…Consequently, Indian soils, in general, are characterized by a state of infertility ( Mahmud, Shamsuddoha & Haque, 2016 ). The ongoing decline in soil health can be attributed to the incorrect application of synthetic fertilizers and the insufficient recycling of organic waste ( Nahar et al, 2017 ). Since the introduction of synthetic fertilizers, rice farmers have increasingly relied on inorganic fertilizers, leading to their excessive use.…”

Effect of Planting Techniques and Nutrient Management Options on Crop Productivity and Soil Health of Wet Rice (Oryza sativa L) in Typic Ustochrept Soils

“…Among them, mainly manual transplanting of seedlings into puddle soil is practiced in India which means a process of cultivating soil in standing water, consumes a large quantity of water and labor [4]. According to Chauhan et al [5], the long-term viability of puddle transplanted rice (PTR) is threatened by increasing production costs (particularly labour) and increasing agricultural labour scarcity, which causes crop establishment to be delayed beyond the optimal time.…”

“…According to Chauhan et al [5], the long-term viability of puddle transplanted rice (PTR) is threatened by increasing production costs (particularly labour) and increasing agricultural labour scarcity, which causes crop establishment to be delayed beyond the optimal time. Transplanting is a resource and cost-intensive procedure since seedbed preparation, seedling raising, and transplanting are all labor-intensive operations [4]. Huge water inputs, labour costs and labour requirements for conventional transplanted puddle rice (CT-TPR) have reduced profit margins to the farmers [6].…”

“…The imbalance usage of fertilizers is responsible for the low productivity and also the continuous use of inorganic fertilizers resulted in declining of soil fertility [7]. Continuous degradation of soil health is caused due to imbalance use of chemical fertilizer and non-recycling of organic matter [4]. The use of inorganic fertilizer in rice cultivation has been progressively increasing since its introduction.…”
