Amendment of Acidic Soil with Lime and Manure for Enhancing Fertility, Nutrient Uptake and Yield of Wheat-Mungbean-Monsoon Rice in the Old Himalayan Piedmont Plain

Abstract

Soil acidic conditions and the decline in soil fertility are among the critical factors that constraint higher crop productivity in the Old Himalayan Piedmont Plain (OHPP), Bangladesh. The study was conducted to evaluate the effect of lime and manure on soil fertility, nutrients and yields of wheat, mungbean and rice. Experiments were done at Agricultural Research Station (ARS), Bangladesh Agricultural Research Institute (BARI) farm and farmer field over two consecutive years with the cropping pattern, namely wheat-mungbean-transplanted (T.) aman rice/monsoon rice. The varieties used were Bijoy for wheat, BARI mung6 for mungbean and Bina dhan7 for T. aman rice. There were nine treatment combinations with three lime levels (0, 1 and 2 ton dololime ha-1) and three manure treatments (poultry manure, farmyard manure and no manure) with three replications. The rate of poultry manure was 3 t ha-1 and that of farmyard manure was 5 t ha-1. Nutrients from manure sources were supplemented with chemical fertilizers to adjust recommended dose. Lime was added to the first crop for entire two crop cycles and manures were applied to the first crop of each crop cycle. Soil pH increased by 0.5-1.11 units, the higher values were observed with higher rates of lime application. Soil organic matter (SOM) increased slightly due to manure treatment. Soil phosphorus availability increased, zinc and boron availability decreased, but the potassium and sulphur availability remained almost unchanged after liming. Application of lime and manure had significant positive effect on the yield of wheat, and their positive residual effects on mungbean and T. aman rice. The effect of 1 t lime ha-1 was comparable with that of 2 t lime ha-1. Between two manures, poultry manure performed better than FYM on crop yields. The trend of plant nutrient uptake by wheat, mungbean and rice followed the trend of these crops yield increase, i.e., crops that were able to uptake more nutrients shown higher yields. The treatment combinations with 1 t ha-1 lime and 3 t ha-1 poultry manure produced an average 35-55% yield benefit over control for the first crop (wheat) and 41-43% yield benefit for the third crop (T. aman rice). This study suggests that dololime @ 1 t ha-1 coupled with poultry manure @ 3 t ha-1 or FYM @ 5 t ha-1 would be an efficient practice for better soil acidic condition, soil fertility and productivity of crops in the Himalayan piedmont soil of Bangladesh.

Effect of boron fertilization on yield and yield attributes of mustard var. BARI Sarisha-14

“…Justified fertilizers and resource use is crucial to maintain productivity of crops (Sultana et al 2015;Hossain and Siddique, 2015). Fertilizers have effect on yield and yield attributes of crops (Sultana et al 2019;Sultana et al 2019a). Usually for mustard production farmers apply NPK fertilizers and do not give focus on other micro element as its necessity is unknown to them.…”

Online Fertilizer Recommendation System (OFRS): A Step Towards Precision Agriculture And Optimized Fertilizer Usage By Smallholder Farmers In Bangladesh

“…some fertilizers applied in excess amount and some applied in low amount) is affecting the availability of soil nutrient unfavorably and deficiency of some plant nutrients is occurring in the agricultural soils of Bangladesh. Besides in some acidic soils of northern Bangladesh [3], due to the unavailability of phosphorus, the unbalanced bulk and unjustified farmer dose that is applied in soil remain unable to meet the P requirement of some crops such as potato. While MOP fertilizer is applied in higher doses during potato cultivation but its residual effect is not considered during the application of fertilizer in the next crop.…”

“…agrochemicals, fertilizers, irrigation, highyielding varieties), may put land quality into stake rising the production cost manifold for the smallholder farmers [1], [2]. The excessive use of fertilizers may cause soil acidification and soil amendments would be necessary to rectify/ameliorate certain soil types for higher yields [3], [4]. Similar and or other forms of land and soil quality degradation [5], [6] and soil fertility decline [7] could evolve in other countries due to intensive agriculture, this is especially so in South Asia and the Pacific region, which accounts for more than 70% of the global agricultural population but only 30% of the world's farmland [8].…”

Response of Sulphur and Zinc Nutrition to the Seed Yield and Oil Content of Mustard (Cv. Bari Sarisha-14)

“…Crop yield reductions are strongly related with soil quality degradation, particularly nutrient depletions which can be attributed to either insufficient fertilizer use or imbalanced fertilization (Roy et al, 2013;Haque et al, 2013;Tan et al, 2005;Chaudhary et al, 2007). Fertilizers have effect on yield and yield attributes of crops and justified fertilizers and resource use is crucial to maintain productivity of crops (Sultana et al, 2019;Sultana et al, 2015). In recent years, deficiency of sulphur has been aggravated in the soil of Bangladesh because of the continuous removal by intensive cropping and tendency to apply NPK fertilizers which is devoid of sulphur.…”
