Background: Cotton is one of the important commercial crops cultivated in India for fibre and oil. The average cotton productivity of India is lower compared to other countries. Among the improved agronomic practices, important yield contributing agro techniques are crop geometry and fertilizer application. Drip irrigation and use of water soluble fertilizers (WSF) by drip system is a recommended practice to increase both water and nutrient use efficiency. Taking this aspect, a field investigation was carried out to find the resource use efficiency, productivity and profitability of inter specific Bt cotton hybrid with different levels crop geometry and drip fertigation. Methods: A field experiment was conducted at TNAU, Coimbatore during 2013 and 2014 for two consecutive years. The experiment was laid out in a strip plot design with three replications. The treatments in main plot consisted of four crop geometry levels (120 x 60 cm, 120 x 90 cm, 150 x 60 cm and 150 x 90 cm) and sub plots consisted of four nutrient levels viz., 75 %, 100 %, 125 % of recommended dose as water soluble fertilizer (WSF) through drip system and as conventional practice. Resource use efficiency (water, nutrient), seed cotton yield and profitability of the system were recorded. Result: The experiment revealed that the fertilizer use efficiency and the efficiency of individual nutrient (partial factor productivity) for the crop geometry of 120 x 90 cm and 75% RDF were higher in both the years. The crop geometry of 120 x 90 cm in combination with 125% RDF effectively utilized the water as indicated by its water use efficiency and comparable results was also obtained with 100% RDF. The mean (2012-13 and 2013-14) seed cotton yield of 2,713 kg ha-1 in 120 x 90 cm kg ha-1 for 125% RDF was 41.5 per cent higher compared to their lower counterpart. Their interaction was significant, consequently the treatment M2S3 (120 x 90 cm and 125% RDF) recorded higher mean (both years) seed cotton of 3,176 kg ha-1 which was nearly 93.7 per cent increase over conventional irrigation and fertilizer application (M4S4). Here M1S2 could be considered as alternate option as it maintained similarity with the best treatment. The gross and net return was estimated to be higher with spacing of 120 x 90 cm with 125 % RDF and however the benefit cost ratio was higher with 120 x 90 cm with 100 % RDF followed by 120 x 60 cm with 100 % RDF.

The Difference

Cotton is the major commercial crop amongst all cash crops in India and provides  livelihood to  more  than  60  million  people  in  its  cultivation,  processing  and  textile  industry.  Cotton  crop  is  infested  by  various  pests  causing  significant  yield  losses therefore Bt cotton was introduced in India to reduce pesticide consumption and also increase  productivity. Since introduction there has been ongoing debate on the superiority and/ or inferiority of Bt cotton over non Bt cotton. Therefore the present study was undertaken to examine the Bt cotton technology on output and efficiency of inputs used in cotton cultivation in Karnataka state of South India during 2007. Primary data was collected from 90 farmers cultivating Bt and non-Bt cotton in Haveri district, Karnataka, India. The Cobb-Douglas production and decomposition analysis techniques were used to estimate the influence of factors and Bt technology on output change. The production function analysis indicated that the co-efficients of expenditure on fertilizers, labour, plant protection chemicals and land were significant in case of Bt cotton cultivation. The result of Resource use efficiency analysis showed that efficient use of labour, fertilizers and seeds had contributed the most to the difference in returns between Bt-cotton and non-Bt cotton cultivation.  Contribution of differences in the quantity of inputs used to higher returns from Bt cotton to the measured difference in gross returns between Bt and non-Bt cotton was 56.56 per cent, while that of the efficiency in the use of inputs was 23.83 per cent.

The field experiments were conducted at Agricultural Research Station, Hukkeri, Belagavi, Karnataka, India during 2018–19 and 2019–20 to study the system productivity and resource use efficiency of alternative cropping systems for sugarcane. There were 11 treatments involving different cropping systems viz., soybean–sorghum–ridge gourd, pigeon pea±green gram (1:1)–beans, pigeon pea±soybean (1:1)–cowpea, soybean–wheat–groundnut, groundnut–sorghum–sesame, maize–cabbage–fallow, soybean–wheat–green gram, maize–wheat–sesame, Bt cotton–groundnut, sugarcane±onion (1:2) and sugarcane (sole) replicated thrice and laid out in randomized complete block design. Among the cropping systems, maize-cabbage-fallow system recorded significantly higher total system productivity (58,234 kg ha-1), water use efficiency (199.67 kg ha-1-mm) and energy use efficiency (129.91 MJ ha-1) compared to rest of the cropping systems. However, sugarcane (sole) recorded (1,11,008 kg ha-1, 68.64 kg ha-1-mm and 16.58 MJ ha-1, respectively). Based on alternative cropping systems involving only field crops, maize-wheat-sesame (9633 kg ha-1, 30.65 kg ha-1-mm and 132.20 MJ ha-1, respectively), soybean-wheat-groundnut (7602 kg ha-1, 27.40 kg ha-1-mm and 32.35 MJ ha-1,, respectively), soybean-wheat-green gram (6424 kg ha-1, 23.05 kg ha-1-mm and 31.91 MJ ha-1, respectively) and Bt cotton-groundnut (4503 kg ha-1, 17.97 kg ha-1-mm and 16.95 MJ ha-1, respectively) were significantly higher. By adopting the alternative cropping systems, there was water saving of approximately 45% compared to sugarcane monocropping and sugarcane±onion (1:2) intercropping.

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.
