Integrated Nutrient Management for Potatomungbean- T.Aman Rice Cropping Pattern Under Level Barind Agroecological Zone

Abstract

A field experiment was conducted at the Multiplication Testing Site (MLT), Joypurhat Sadar upazila with Potato-Mugnbean -T. Aman rice cropping pattern during November/2007 to November/2008 to verify different nutrient management approaches and to determine the economic dose of fertilizer for the said cropping pattern. The experiment was designed with five treatments for whole of the cropping pattern in a randomized complete block design with six replications. The treatments were, soil test based fertilizer dose for moderate yield goal, soil test based fertilizer dose for high yield goal, integrated plant nutrient management, farmers' practice, and control. Cowdung was applied at the first crop potato only in the cropping sequence. The varieties for potato, mungbean and T. Aman rice were Diamant, BARI Mung-6, and BR11, respectively. The results demonstrated that the tuber yield of potato, seed yield of mungbean, and grain yield of T. Aman rice were significantly influenced by the different treatments. The highest tuber yield (25.01 t/ha) was obtained from integrated plant nutrient management treatment. In mungbean, the highest seed yield (1384 kg/ha) was also recorded from NPKS for high yield goal with residual cowdung treatment. The results of NPKS application for high yield goal with residual cowdung had a positive effect on seed yield of mungbean. Grain and straw yields of T. Aaman rice were also significantly influenced by different treatments. The highest grain yield (5.68 t/ha) and straw yield (5.82 t/ha) were also observed in NPKS for high yield goal with residual cowdung treatment. The results also indicated that the residual cowdung had a positive effect on grain and straw yields of T. Aman rice. Cost and return analysis of different nutrient management packages for the whole cropping pattern showed that the highest marginal benefit cost ratio (8.64), gross return (Tk. 3,79,960/ha) and gross margin (Tk. 3,43,360/ha) were obtained from integrated plant nutrient management treatment and the lowest from soil test based fertilizers for moderate yield goal treatment. So, considering crop productivity, economic return, and soil fertility, integrated plant nutrient management for high yield goal with 5 t/ha cowdung could be recommended for the Potato-Mungbean-T Aman rice cropping pattern at Joypurhat and similar soils of Level Barind agroecological zone for sustainable higher yield.

Use of Integrated Nutrient Management to Enhance Soil Fertility and Crop Yield of Hybrid Cultivar of Brinjal (Solanum melongena L.) Under Field Conditions

“…Sufficient and balanced application of organic and inorganic fertilizers is a major component of INM [24,43]. Successful INM extension will also require greater monitoring and testing of plants and soils [25,31]. Monitoring will help ensure that an environment conducive for optimal plant growth and crop yield can be established through nutrient application and soil reclamation [29,31,43].…”

“…In addition to the primary nutrients, less intensively used secondary nutrients (sulfur, calcium, and magnesium) are necessary as well [18][19][20][21][22]. A number of micronutrients such as chlorine, iron, manganese, zinc, copper, boron, and molybdenum also influence plant growth [23][24][25]. These micronutrients are required in small amounts (ranging from a few grams to a few hundred grams per hectare) for the proper functioning of plant metabolism.…”

Improving Performances of Late Transplant Aman Rice Through Spacing and Nutrient Management Options

“…Sarkar et al (2014) also indicated the highest number of effective tillers hill -1 , grains panicle -1 , panicle length and grain yield were recorded in the treatment using 75% recommended dose of fertilizer. Mollah et al (2011) found that cow dung had a positive effect on grain and straw yields of Aman rice.…”

Crop Establishment and Nutrient Management for Dry Season (Boro) Rice in Coastal Areas

“…Producing FYM in situ by integrating animals into the rice-based cropping system, as generally seen in coastal areas of India, may make this possible. Applying organic manure on the basis of its major nutrient concentrations rather than using bulk quantity, as is generally done by farmers in South Asia (Barik et al, 2006), and replacing a portion of chemical fertilizers by organic manure on the basis of soil test-based fertilizer dose (Mollah et al, 2007), are steps toward a more sensible use of organic sources to make them more economically sound for coastal farmers.…”
