A field experiment was conducted at Imphal, Manipur during 2010-12 to study the effect of liming, planting time and tillage on system productivity, resource use efficiency and energy dynamics of rice (Oryza sativa L.) - lathyrus (Lathyrus sativus L.) cropping system. The experiment was laid out in split plot design with 3 replications. The treatment consisted of two factors i.e. liming (liming and no liming) and planting time (early and normal) given to rice crop during kharif season in the main plots and two tillage practices (no tillage and conventional tillage) were given in the succeeding lathyrus crop during the rabi season in the sub plots. Results showed that application of lime @ 500 kg CaCO3/ha before planting rice improved system productivity marginally in terms of rice-equivalent yield (REY of 6.32 t/ha) and water use efficiency (WUE) of the system (20.51 kg/ha-mm), however, it failed to increase benefit: cost (B: C) ratio. Advancing planting time of rice 15 days ahead of normal planting enhanced growth and yield of succeeding lathyrus crop resulting in increase of REY, land use efficiency (LUE), production efficiency (PE), and partial factor productivity (PFP) of the system by 19.3, 1.7, 17.0 and 17.0 %, respectively and moreover, it recorded higher system B:C ratio (1.20). No tillage enhanced PFP, NUE, WUE and B: C ratio of the system, while conventional tillage increased energy consumption by 9.45 %.

Groundnut is an important oilseed and Anantapur district of Andhra Pradesh occupies a prominent position both in acreage and production. Data was obtained from forty farmers using structured questionnaire and the input-output relation of groundnut production via Cobb-Douglas production function was examined in this study. It was found that the sum of elasticities was 0.73. The result of the t’ test proved that in groundnut farms S bi  was less than one, it indicates decreasing returns to scale, which indicates some of the inputs are excessively used. The production elasticities for human labour, bullock labour, machine labour charges, seed cost and pesticides were positive and significant where as farm yard manure and fertilizers cost was negative which showed that increase in these costs result in decrease in output. The MVP of selected input variables were estimated to be 25.08, 4.21, 6.74, 1.87, 17.34, -19.46 and -7.67 showing that FYM and fertilizers are over utilized and the rest of the variables are underutilized. The groundnut production in the study area would be profitable.

The study was conducted using purposive cum random sampling technique and two hundred respondents comprised of 100 each borrowers and non-borrowers were selected from two block of district including marginal, small and medium categories of farm size. Primary data were collected through personal interview technique and required secondary information was taken from the record available at district and block level. Simple tabular and functional analysis and Garrett ranking were done to draw inferences. As per the result obtained from the study, no much difference was seen between the resource use efficiency of borrower and non-borrower farms and constraints faced by borrower. Since banana is a cash crop and it needs initial costs for its establishment, and after harvesting the crop regular source of income was generated by selling of suckers (seed) plant and its fruits. It’s by-product, leaves, etc. also used for various purposes. Minute inspection of the analysis showed that finance played important role for initiating the cultivation of banana crops showed the resource use efficiency that there is no considerable difference found on sample farms of borrower and non-borrower categories. Constraints faced by majority of the farmers were mainly delay in disbursement of loan and lack of the repayment period insufficient and improper management for withdraws on KCC.
