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.

AbstractThe cotton-wheat double-cropping system is widely used in the Yellow River Valley of China, but whether and how different planting patterns within cotton-wheat double-cropping systems impact heat and light use efficiency have not been well documented. A field experiment investigated the effects of the cropping system on crop productivity and the capture and use efficiency of heat and light in two fields differing in soil fertility. Three planting patterns, namely cotton intercropped with wheat (CIW), cotton directly seeded after wheat (CDW), and cotton transplanted after wheat (CTW), as well as one cotton monoculture (CM) system were used. Cotton-wheat double cropping significantly increased crop productivity and land equivalent ratios relative to the CM system in both fields. As a result of increased growing degree days (GDD), intercepted photosynthetically active radiation (IPAR), and photothermal product (PTP), the capture of light and heat in the double-cropping systems was compared with that in the CM system in both fields. With improved resource capture, the double-cropping systems exhibited a higher light and heat use efficiency according to thermal product efficiency, solar energy use efficiency (Eu), radiation use efficiency (RUE), and PTP use efficiency (PTPU). The cotton lint yield and biomass were not significantly correlated with RUE across cropping patterns, indicating that RUE does not limit cotton production. Among the double-cropping treatments, CDW had the lowest GDD, IPAR, and PTP values but the highest heat and light resource use efficiency and highest overall resource use efficiency. This good performance was even more obvious in the high-fertility field. Therefore, we encourage the expanded use of CDW in the Yellow River Valley, especially in fields with high fertility, given the high productivity and resource use efficiency of this system. Moreover, the use of agronomic practices involving a reasonably close planting density, optimized irrigation and nutrient supply, and the application of new short-season varieties of cotton or wheat can potentially enhance CDW crop yields and productivity.

Main objective of study was comparative analysis of Laser Land Levelling (LLL) vis-a-vis Conventional Land Levelling (CLL) in terms of resource use efficiency. Regression analysis along with economic concept of marginal value productivity (MVP) and marginal factor cost (MFC) were used to analyse resource use. Six variables were used to regress yield. The results of the study revealed that highest resource use efficiency were obtained in case of seed, while it was observed lowest in case fertilizers under laser land levelling (LLL) in paddy. Whereas, under conventional land levelling (CLL), highest resource use efficiency was found to be in case of labour while least resource use efficiency was obtained in irrigation. Similarly, in case of wheat highest and lowest resource use efficiency under laser land levelling technology were observed in inputs viz: seed and plant protection chemicals, respectively while, under conventional land levelling it was for inputs like labour and seed, respectively. Hence, study highlighted the strength of resource conservation potential of laser land levelling technology. Two variables i.e. irrigation and fertilizer impacted significantly with the adoption of laser land levelling, validated the outcomes of study by difference between MVP and MFC for these two particular inputs were found to be positive and close to zero indicated efficient utilizations of these resources. Hence, it is suggested that adoption of laser land levelling should be promoted on wider scale to tap its resource conservation potential.
