This study examined the adaptation of lentil (Lens culinaris Medik. cv. Digger) to dryland Mediterranean-type environments of southern Australia and determined the effect of time of sowing on growth, yield, and water use. Phenology, canopy development, radiation absorption, dry matter production and partitioning, seed yield, and water use were measured from a range of sowing times at a number of field locations in south-western Australia in 1994, 1995, and 1996. Contrary to previous results with poorly adapted cultivars, our study showed that lentil is well adapted to low to medium rainfall regions (300-500 mm/year) of south-western Australia and that seed yields greater than 1·0 t/ha and up to 2·5 t/ha can be achieved when sown early. Even in the dry season of 1994 when May-October rainfall was <200 mm, yields of approximately 1·0 t/ha were produced from early sowings. Seed yields were reduced with delayed sowing at rates of 4-29 kg/ha · day. Sowing in late April or early May allowed a longer period for vegetative and reproductive growth, rapid canopy development, greater absorption of photosynthetically active radiation, more water use, and, hence, greater dry matter production, seed yield, and water use efficiency than when sowing was delayed. Early-sown lentils began flowering and filling seeds earlier in the growing season, at a time when vapour pressure deficits and air temperatures were lower, and used more water in the post-flowering period when compared to those treatments where sowing was delayed. The values of water use efficiency for dry matter and grain production, and transpiration efficiency, for early-sown lentil (up to 30 kg/ha · mm, 11 kg/ha · mm, and 20 kg/ha · mm, respectively) were comparable to those reported for cereal and other grain legume crops in similar environments. The development of earlier flowering cultivars than Digger with greater dry matter production together with improved agronomic packages will increase and stabilise lentil yields in low rainfall environments of southern Australia.

Field experiment was conducted at Instructional Farm, Jaguli (Mohanpur), Bidhan Chandra Krishi Viswavidyalaya, West Bengal, India during two consecutive summer seasons of 2010-11, and 2011-12. The experiment was laid out in split-plot design having 4 levels of irrigation– rainfed without mulch, rainfed with mulch, irrigation at IW (depth of irrigation water) / CPE (Cumulative pan evaporation) ratios of 0.5 and 0.75 in main-plot and 4 inter cropping systems, sole maize, sole mungbean, maize + mungbean (1:1 row ratio) and maize + mungbean (3:2 row ratio) considered as sub-plot treatments replicated thrice. Results revealed that application of irrigation and intercropping systems markedly influenced the growth, yield and yield components (number of cobs/plant, number of grains/cob in case of maize and number of pods/plant and number of seeds/pod in case of mungbean) where the maximum value of these components were recorded with the application of irrigation at IW/CPE ratio 0.75 in sole crop. Maize-mungbean in 3:2 row ratio yielded higher than that of 1:1 intercropping system which might be due to less light interception and more competition for water and nutrition between both the crops. CU of water increased with the increasing levels of irrigation and the maximum value (17.75 kg ha-1 mm- 1) of WUE (water use efficiency) was observed with irrigation at IW: CPE ratio 0.75 under intercropping system of maize : mungbean in 3:2 row ratio followed by IW: CPE ratio 0.50. Among the sole crop, maximum WUE was with IW/CPE ratio 0.75 might be due to more consumption of water corresponding to production potential of maize, while, it was more under rainfed with mulch in mungbean. The relative crowding coefficient (RCC) also revealed both the intercropping systems were advantageous and the land equivalent ratio (LER) increased with the level of irrigation.Thus, maize grown in association with mungbean (3:2 row ratio) were found to be more profitable (B:C ratio of 2.58) with higher monetary advantage as compared to sole crop of maize (B:C ratio of 1.98) with the application of irrigation at IW: CPE ratio of 0.75 in new alluvial zone of West Bengal.SAARC J.

Competitive crops or cultivars can be an important component of integrated weed management systems. A study was conducted from 2003 to 2006 at four sites across semiarid prairie ecoregions in Saskatchewan and Alberta to investigate the productivity and quality of canola (Brassica napusL.) and mustard cultivars under weed competition. Four open-pollinated canola cultivars, four hybrid canola cultivars, two canola-quality mustard and two oriental mustard cultivars [Brassica juncea (L.) Czern. & Coss.], and two yellow mustard (Sinapis alba L.) cultivars were grown under weedy and weed-free conditions. When combined across site-years, crop aboveground biomass at maturity and seed yield were reduced by weed interference, except for yellow and oriental mustard. However, seed oil and protein content of cultivars were not affected by weed competition. Among crop types, yellow and oriental mustard were best able to maintain biomass and seed yield under weed interference, followed in decreasing order of competitiveness by hybrid and open-pollinated canola, then canola-quality mustard. Key words: Brassica napus, Brassica juncea, Sinapis alba, weed competition

Weed management in blackgram is one of the most efficient ways to improve its yield, as uncontrolled weed growth causes a significant decrease in crop yield. A field experiment was performed at Berthin, Himachal Pradesh, India, to investigate the efficacy, energy use efficiency (EUE), and carbon footprints of weed management tactics. Twelve weed control treatments were tested applied alone or in combination at pre and post emergence stages. The most prominent weeds were Cyperus iria, Dactyloctenium aegyptium, and Echinochloa colona, which caused a 68.1% loss in unweeded conditions. The application of weed control treatments reduced the weed count at 60 DAS from around 50% to 90%. The most efficient weed control treatment was pre-emergence (PRE) use of ready mix imazethapyr 35% + imazamox 35% WG @ 80 g ha−1, which resulted in a minimum weed infestation (i.e., weed count and weed biomass) and consequently highest yield. Its efficacy in weed control treatment was on par with PRE use of ready mix imazethapyr (35%) + imazamox (35% WG @ 70 g ha−1. Maximum energy use efficiency was also obtained upon PRE use of imazethapyr (35%) + imazamox (35% WG) @ 80 g ha−1 (8.27), trailed by PRE use of imazethapyr + imazamox @ 70 g ha−1 (7.84), mainly because of the higher yield obtained in these treatments which shows their efficiency in energy conversion. The carbon footprints were observed to be the lowest in ready mix combination of imazethapyr (35%) + imazamox (35% WG) applied at 80 g ha−1 (0.11 kg CE kg−1 yield), followed by imazethapyr (35%) + imazamox (35% WG) applied at 70 g ha−1 (0.12 kg CE kg−1 yield), as it resulted in the lowest emission per unit output production.

This research was conducted to investigate the effect of different herbicides with weed management practices on growth and yield performance of mungbean genotypes. The experiment consisted of two factors were mungbean genotypes and weed management. There were two genotypes namely BARI Mung 6 and BARI Mung 8. While there were five weed management practices namely control/no weeding and without herbicide application (T1), hand weeding at 20 and 40 DAS (T2), pre emergence herbicide (Panida) at 1-2 DAS (T3), pre emergence herbicide (Neon) at 2-3 DAS (T4), and post emergence herbicide (Neon) at 10-15 DAS+hand weeding (T5). The results revealed that BARI Mung 6 stand superior to BARI Mung 8 in respect of dry matter content/plant, pods/plant, seeds/plant, seed yield, and 1000 seed weight. Among weed management practices, maximum plant height (53.70 cm), dry matter weight/plant (17.96 g), pods/plant (18.31), seeds/plant (171.47), maximum weed control efficiency (33.78 %) obtained from T3 treatment. Based on the interaction effect showed that BARI Mung 6 weeded with pre emergence herbicide (Panida) at 1-2 DAS produced maximum seed yield (1.79 t/ha) as well as yield attributes showed 2.29 % higher seed yield.

Energy being the critical aspect of agricultural production, the modern agricultural system takes into account all the agricultural operations in terms of energy input and the yield obtained as energy output. It is this energy balance equation which describes the viability of a system. Depending upon the variation in energy consumption among various agro–climatic and environmental conditions and the output therein, a wide variation exists in the viability of these systems. In the present study, the energy balance in Kala zeera management system was taken into consideration. Data and information were collected and different energy use efficiency indices were calculated. Amon the production practices in Kala zeera cultivation, consumed root tubers for sowing were the most energy consuming input (43.32%) followed by diesel fuel (20.28 %) and Nitrogen (18.30). the total energy input could be classified in Kala zeera fields as direct ( 10.80%), indirect (25.60%), renewable (43.3%) and non-renewable (20.27%). Overall in view of sustainability,it is recommended that major input consumptive processes shall be optimized to increase energy use efficiency

A two year experiment was conducted at the BCKV with four mungbean varieties (Pant Mung-5, Bireswar, RMG-62 and Sukumar) sown under three dates (15th February, 1st and 15th March) in a split plot design where dates of sowing and varieties were allotted to main and sub plot treatments respectively with three replications. PAR was recorded with the help of line quantum sensor. Dry matter accumulation, yield attributes and yield were measured. Canonical correlation and correspondence analysis showed that absorbed PAR during 32 to 46 days after emergence (DAE) increased dry matter, pod and seed yield. PAR use efficiency (PARUE) of mungbean ranged from 0.75 to 0.88 g MJ-1 for seed yield. PARUE for dry matter production was maximum during 39 to 46 DAE. According to PARUE and heat use efficiency, Pant Mung-5 should be sown within 1st March in this zone. Growing degree day requirement gradually increased with delayed sowing.

Utilization of adequate fertilizer rate enhances soil physical and chemical properties, minimizes soil nutrient imbalance, and promotes better crop growth and development. The study investigated the influence of varying rates of chicken manure and NPK fertilizers as it affected growth, nutrient uptake, seed yield, and oil yield of sunflower on nutrient-limiting soil. Field experiments were carried out during 2014 and 2015 planting seasons for both main and residual studies. There were eight treatments comprising four rates of chicken manure (5, 10, 15, and 20 t·ha−1), three rates of NPK (30, 60, and 90 kg·N·ha−1), and control. The experiment was laid out in a randomized complete block design with three replicates. Growth, yield, dry matter and proximate, nutrient uptake concentration, and oil content were determined following standard procedures. Data were analyzed using ANOVA, and means were compared with the Duncan multiple range test (DMRT) at p≤0.05. Performance of sunflower was superior on the field fertilized with 10 t·ha−1 chicken manure which was comparable to 90 kg·N·ha−1 NPK fertilizer. Sunflower seed yield and oil quality were superior in plots supplied with 10 t·ha−1 chicken manure which was comparable to 60 kg·N·ha−1 NPK. Growth, yield, dry matter, and proximate content were least in the unfertilized plots.
