RÉSUMÉ
The present study was conducted in Hanumangarh district of Zone IB of Rajasthan. This district have Rainfed micro-farming situation. Hence, Hanumangarh district of Rajasthan was selected. In this district two villages were selected from Nohar tehsil. A sample of 25 farmers from each village was selected. The study was aimed at examining compound growth rate, cost and returns, resource use efficiency and farm income inequalities. Primary data were collected on pre-structured schedules for agriculture year 2017-18. In the study found that CAGR of area, production, and productivity in period first was positive but in period second this found was negative except positive productivity in Rajasthan. Average cost per hectare of pearl millet was ? 13955.07 and gross income on was ? 33646.67. The Cobb Douglas production function, revealed that in pearl millet crop weeding intercultural operation were underutilized. Gini coefficient in farm household was 0.311 in Rain-fed micro farming situation.
RÉSUMÉ
Aim: The aim of the present study was to assess the influence of different integrated crop management (ICM) practices on productivity, resource-use efficiency and energetics of pigeonpea crop so as to overcome various production- and climatic-vulnerabilities in Indo-Gangetic Plains Region (IGPR). Methodology: A study was conducted during Kharif 2017 in pigeonpea under pigeonpea–wheat cropping system at IARI, New Delhi, India to assess the influence of nine different ICM modules [Conventional tillage (CT) based: 04 (ICM1–ICM4); Conservation agriculture (CA) based: 04 (ICM5–ICM8); Organic agriculture based: 01 (ICM9)] on productivity, PAR interception, resource-use-efficiency and energetics in pigeonpea in randomized block design replicated thrice. Results: Pigeonpea seed yield was significantly higher in ICM7 (1.92 t ha-1) – a CA-based ICM module which was followed by ICM5, ICM8 and ICM6. In general, the CA based ICM modules showed an edge over CT based ICM modules with reference to growth, yield and PAR interception. The resource-use-efficiency indices like total water-use-efficiency (TWUE), irrigation water-use-efficiency (IWUE), economic water-productivity (WPE), partial factor productivity of applied nutrients (NPK) also exhibited same trend as that of seed yield with highest TWUE (2.96 kg ha-mm–1) and WPE (104.5 INR ha-mm–1) in ICM7 module. The energy output was highest in ICM7 (2, 23, 664 MJ ha-1) followed by ICM5, ICM8 and ICM6. The trend of energy-use-efficiency was ICM4>ICM2>ICM1>ICM3>ICM5>ICM7>ICM6>ICM8>ICM9, respectively. Interpretation: Conservation agriculture (CA) based modules like ICM7 can be recommended to the farmers for enhancing the plant growth, PAR interception, crop productivity, resource-use efficiency and energetics in pigeonpea alone or on pigeonpea-wheat cropping system basis in semi-arid Indo-Gangetic plains region (IGPR).
RÉSUMÉ
The study was undertaken in Rajasthan with the objective to examine the input-output relationships and assess the resource use efficiency in milk production. The study covered 60 dairy households. The results of Cobb-Douglas production function revealed that concentrate had positive and significant influence on returns from buffalo, crossbred cow and local cow milk. Green fodder and labour were also significantly influenced the returns from buffalo, crossbred and local cow. The results of resource use efficiency and marginal value productivity of inputs indicated that inputs were not optimally utilized by dairy households. The green fodder, dry fodder, concentrate and labour in buffalo, concentrate and labour crossbred cow milk production and green fodder in local cow milk production were found to be over utilized in study area resulting higher per litre cost of milk production on these species.
