Attempts have been made in this paper to overview the present agricultural inputs for crop production and crop economy in the lower Gangetic plain. Results of the field survey show that the average labour requirement of Boro rice production is 35 person-days/acre. The fertilizer application by the farmers is not balanced and is well below the recommended doses. N, P2O5, K2O ratio used by the farmers was 7:3:1 against the appropriate ratio of 5:4:3 for HYV Boro rice. The cost of Boro rice cultivation has been estimated on the basis of input use. The rice cultivation costs were Tk.14,335, Tk 13,875 and Tk. 11,271 per acre for the water buyer, water seller with diesel pump and water seller with electric pump respectively. Labour and irrigation costs together normally account for two- thirds of the total cost of production - increases in the prices of these inputs can greatly depress Boro rice profitability. Moreover, Gross income of the water sellers from major crops is about 32% higher than that of the water buyers. The study also shows that the total cost for a Shallow Tube Well (STW) run by diesel motive power is almost twice that for electric motive power. If groundwater irrigated agriculture system is framed in a comprehensive manner, this could play an important role in poverty alleviation. DOI: DOI: http://dx.doi.org/10.3329/jasbs.v38i1.15318 J.

Soil salinity is one of the most important abiotic stresses for crop production. A study was conducted to analyze the relationship between salinity level and nutrient contents in some popular vegetables grown in some selected tidal areas of Barguna and Patuakhali districts of Bangladesh. Samples of six different vegetables such as bottle gourd leaf (Lagenaria siceraria), sweet gourd leaf (Cucurbita maxima), radish leaf (Raphanus sativus), bean (Lablab niger), red amaranth (Amaranthus gangeticus) and spinach (Spinacia oleracea) were collected along with soils from different locations of the study areas and were analyzed for phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), sulphur (S) contents. Soil pH and electrical conductivity (EC) were determined. In saline areas, comparatively lower amounts of P, K, Ca, Mg and S were detected in most of the collected vegetables than those of non-saline areas. Conversely, bottle gourd leaf, radish leaf and bean accumulated comparatively higher amount of Ca at higher salinity levels. The uptake of P by bottle gourd leaf and radish leaf, Mg by bottle gourd leaf and red amaranth was also higher in the saline soil. The inconsistent uptake of Ca, Mg and P were found in some vegetables due to the differences of fertilizer application and intercultural operation. The vegetables could tolerate moderate soil salinity (soil EC up to7.9 dSm-1) and might be recommended to grow in the tidal saline areas of Barguna and Patuakhali districts of Bangladesh.

Declination of available water resources is threatening the dry season crop production in Bangladesh. Sustainable water management is crucial need to meet future food production. This study was aimed to determine futuristic water management strategy for rice cultivation. Both surface and groundwater is getting scarce in north-west region, whereas abundant of fresh surface water creating opportunities to irrigate dry season crops in south-central region. This study has outlined irrigation management for rice cultivation and groundwater utilization in water scarce area of north-west region. More than 75% of annual rainfall occurred during monsoon and crops other than monsoon often faced water shortage. Timely establishment of T. Aus rice on 01 May accounted average 183 mm supplemental irrigation for north-west and south-west region. Transplanting of T. Aman rice before 24 July found the low risk period of drought and gave about 1 t ha-1 yield advantage than late transplanting after 15 October. Supplemental irrigation in drought year gave up to 26% yield advantage than the rain-fed condition of T. Aman rice in experimental plot. Over exploitation of groundwater by famers for crop cultivation makes the groundwater status worsen. Farmers used 38% excess water than the actual requirement for Boro rice cultivation. For that annual groundwater withdrawal was higher than annual recharge causing groundwater level depletion in most of the districts. Groundwater table went below suction limit of shallow tubewell (STW) during dry season and thus it become unable to operate. Improved distribution system with plastic pipe, buried pipe could save about 25% of irrigation water. Alternate wetting and drying (AWD) irrigation method saved 20-25% water than farmer’s practice. Application of these on-farm water management technologies in Boro rice reduced water demand and made the groundwater balance positive as well as reduced the groundwater withdrawal pressure. On the contrary, irrigation with less saline surface water resources in river and canals of south central regions could expand Boro production and increased land productivity. Intervention of low lift pump with plastic pipe distribution in non-saline tidal areas could increase land productivity. Besides, trapped freshwater in to the canals inside the polders and re-excavation of these canals would make crop intensification. Thus, additional food production could help to achieve sustainable development goal and sustained food security. Bangladesh Rice J. 25 (1) : 37-50, 2021

This study aims to analyze the share of fertilizer costs on the total cost of crop and   the effect of fertilizer application on the performance of crop production in Indonesia.  The data used in the study was time series data, it was collected from FAOSTAT published Food and Agriculture Organization (FAO) and Statistics Center Bureou (BPS). The first objective was analyzed by descriptive statistics, whereras the second objective was analyzed by econometrics techniques, namely, linear production function, logarithmic function and quadratic function.  The results showed that the percentage fertilizer cost on the total cost of crop production were quite small compared to the cost of labor and land rental, which were 10.40 percent for wetland paddy, 7.80 percent for upland paddy, 12.00 percent for maize, and 4.80 percent for soybean.  The applications of fertilizer played important roles in production performance of paddy, maize, and soybean.  The magnitude and significant level of each fertilizer differ by crop production.  The study gives better policies to secure the availability of fertilizer to improve the performance of Indonesian crop production.Key words: cost,  fertilizer, production  function

A study was undertaken in Bhagwanpur distributary of Vaishali Branch Canal in Gandak Canal Command Area, Bihar to optimally allocate land area under different crops (rice and maize in kharif, wheat, lentil, potato in rabi and green gram in summer) in such a manner that maximizes net return, maximizes crop production and minimizes labour requirement employing simplex linear programming method and Multi-Objective Fuzzy Linear Programming (MOFLP) method. Maximum net return, maximum agricultural production, and minimum labour required under defined constraints (including 10% affinity level of farmers to rice and wheat crops) as obtained employing Simplex method were ` 3.7 × 108, 5.06 × 107 Kg and 66,092 man-days, respectively, whereas Multi-Objective Fuzzy Linear Programming (MOFLP) method yielded compromised solution with net return, crop production and labour required as ` 2.4 × 108, 3.3 × 107Kg and 1,79,313 man-days, respectively. As the affinity level of farmers to rice and wheat crops increased from 10% to 40%, maximum net return and maximum production as obtained from simplex linear programming method and MOFLP followed a decreasing trend and minimum labour required followed an increasing trend. MOFLP may be considered as one of the best capable ways of providing a compromised solution, which can fulfill all the objectives at a time.

Abstract. Land degradation has been a persistent problem in Senegal for more than a century and by now has become a serious impediment to long-term development. In this paper, we quantify the impact of land degradation on crop yields using the results of a nationwide land degradation assessment. For this, the study needs to address two issues. First, the land degradation assessment comprises qualitative expert judgements that have to be converted into more objective, quantitative terms. We propose a land degradation index and assess its plausibility. Second, observational data on soils, land use, and rainfall do not provide sufficient information to isolate the impact of land degradation. We, therefore, design a pseudo-experiment that for sites with otherwise similar circumstances compares the yield of a site with and one without land degradation. This pairing exercise is conducted under a gradual refining of the classification of circumstances, until a more or less stable response to land degradation is obtained. In this way, we hope to have controlled sufficiently for confounding variables that will bias the estimation of the impact of land degradation on crop yields. A small number of shared characteristics reveal tendencies of "severe" land degradation levels being associated with declining yields as compared to similar sites with "low" degradation levels. However, as we zoom in at more detail some exceptions come to the fore, in particular in areas without fertilizer application. Yet, our overall conclusion is that yield reduction is associated with higher levels of land degradation, irrespective of whether fertilizer is being applied or not.

ABSTRACT: Irrigation using produced water, which is generated during crude oil and gas recovery and treated by the exploration industry, could be an option for irrigated agriculture in semiarid regions. To determine the viability of this option, the effects of this treated water on the nutritional status of plants should be assessed. For this purpose, we examined the nutritional changes in sunflowers after they were irrigated with oil-produced water and the effects of this water on plant biomass and seed production. The sunflower cultivar BRS 321 was grown for three crop cycles in areas irrigated with filtered produced water (FPW), reverse osmosis-treated produced water (OPW), or ground water (GW). At the end of each cycle, roots, shoots, and seeds were collected to examine their nutrient concentrations. Produced water irrigation affected nutrient accumulation in the sunflower plants. OPW irrigation promoted the accumulation of Ca, Na, N, P, and Mg. FPW irrigation favored the accumulation of Na in both roots and shoots, and biomass and seed production were negatively affected. The Na in the shoots of plants irrigated with FPW increased throughout the three crop cycles. Under controlled conditions, it is possible to reuse reverse osmosis-treated produced water in agriculture. However, more long-term research is needed to understand its cumulative effects on the chemical and biological properties of the soil and crop production.

Abstract. Phosphorus (P) plays a vital role in global crop production and food security. In this study, we investigate the changes in soil P pool inventories calibrated from historical countrywide crop P uptake, using a 0.5-by-0.5° spatially explicit model for the period 1900–2010. Globally, the total P pool per hectare increased rapidly between 1900 and 2010 in soils of Europe (+31 %), South America (+2 %), North America (+15 %), Asia (+17 %), and Oceania (+17 %), while it has been stable in Africa. Simulated crop P uptake is influenced by both soil properties (available P and the P retention potential) and crop characteristics (maximum uptake). Until 1950, P fertilizer application had a negligible influence on crop uptake, but recently it has become a driving factor for food production in industrialized countries and a number of transition countries like Brazil, Korea, and China. This comprehensive and spatially explicit model can be used to assess how long surplus P fertilization is needed or how long depletions of built-up surplus P can continue without affecting crop yield.

Precision farming is the technique of applying the right amount of input (fertilizer, pesticide, water etc.) at the right location at the right time to enhance production, decrease input and/or protect the environment, Site-Specific Crop Management (SSCM), Farming by-the-foot, Farming soils and not fields, Prescription farming, Environmentally-friendly farming & Information-based crop production. Thus, precision farming is an appealing concept and its principles quite naturally lead to the expectation that farming inputs can be used more effectively, with subsequent improvements in profits and environmentally less burdensome production. The precision farming developments of today can provide the technology for the environment friendly agriculture of tomorrow. Especially in the case of small farmers in developing countries like India, precision farming holds the promise of substantial yield improvement with minimal external input use. In order to achieve optimal production with less inputs, Precision Farming Development Centre (PFDC), Hyderabad, Telangana, India, plays important role in Precision farming by reaching local farmers to introduce precision farming techniques. PFDC Hyderabad attracts local farmers with tailor made annual action plans which includes both research and extension part. This study shows how PFDC Hyderabad uplifts both financial and social status of local farmers by introducing them to Precision Farming.
