Phosphorus Application

A field experiment was conducted in a high phosphorus soil in the southern district of Kerala during January to March 2018 to assess the effect of varying levels of P, K and Zn and their interactions on the productivity of grain cowpea. The treatments included two levels of P, three levels of Zn and two levels of K and was laid out in factorial RBD with three replications. The results of the study revealed that significantly higher yield attributes and yield (pod and grain) were realized through foliar application of Zn as ZnSO4 twice @ 0.025% at branching and at flowering, along with 10 kg K2O ha-1 in the high P soil. The yield was 58 per cent higher than the yield at the lower levels of P, K and Zn tried. Economic analysis also revealed higher benefit cost ratio (1.36) for the combination. Phosphorus application may be skipped in the nutrient package for grain cowpea in high soils. Based on grain yields, it could be interpreted that a negative interaction existed between P and Zn and also between Zn and K. The interaction between P and K was not significant.

Dry direct-seeded rice has been shown to save irrigation water and labor. Nonetheless, irrigation management in dry direct-seeded rice has received very little attention. Here, we examined the potential of different irrigation regimes: aerobic rice (AR), alternate wetting and drying (AWD) and continuous flooding (CF) in dry direct-seeded rice cultivation on two rice cultivars (Pride-1 (hybrid indica) and NB-1 (inbred indica)). Growth, yield attributes, grain yield, total water input, water productivity and benefit cost ratio were measured. Our results showed that AR saved 11.22 and 28.40%, and 5.72 and 32.98% water compared with AWD and CF during 2018 and 2020, respectively. There was a significant difference in grain yield among treatments and cultivars. AWD and CF produced statistically same total dry weight and grain yield, while AR reduced the total dry weight by 31.34% and 38.04% and grain yield by 34.82% and 38.16% in comparison to AWD and CF, respectively, across the years. Except for 1000-grain weight and harvest index in AWD and CF, further differences in total dry weight and grain yield among irrigation treatments were primarily correlated with variations in yield attributes. Among the cultivars, hybrid rice performed better than inbred rice. Over the two-year period, hybrid rice increased total dry weight, grain yield, and water productivity by 9.28%, 13.05%, and 14.28%, respectively, as compared to inbred rice. Regarding water productivity (WP), the maximum percentage (40.90 and 26.53%) was recorded for AWD compared to AR and CF. Among cultivars, more water productivity (14.28%) was calculated for hybrid rice than inbred one. Chlorophyll and carotenoid contents, leaf area index and crop growth rate contributed to higher grain yield of hybrid rice under AWD and CF. In contrast to WP, the maximum benefit cost ratio was estimated to be higher for CF than that of AR and AWD. For the cultivars, the maximum value (2.26 in 2018 and 2.32 in 2020) was calculated for hybrid rice compared with the inbred one. In conclusion, these results suggests that AWD with maximum WP and CF with maximum BCR could be more efficient approaches than AR. Under CF, hybrid rice cultivars with higher yield and yield-related attributes, WP and BCR performed better.

Field experiments were carried out in the Agronomy field of BARI, Joydebpur, RARS, Jamalpur and RARS, Ishurdi during two consecutive kharif seasons of 2012 and 2013 to determine the suitable plant spacing and optimum fertilizer dose for higher yield of mukhikachu. Three levels of spacing viz., 60 cm x 60 cm, 60 cm x 45 cm and 60 cm x 30 cm and three levels of fertilizer dose viz., recommended dose (3000-96-27-81-18 kg ha-1 of CD-N-P-K-S), 25% less than the recommended dose and 25% higher than the recommended dose were used as treatment variables. The experiments were laid out in factorial randomized complete block design with three replications. Results revealed that the closer spacing (60 cm x 30 cm) in combination with 25% higher than the recommended fertilizer dose gave the maximum edible yield of mukhikachu (two years average) at all locations (20.04 t ha-1, 20.75 t ha-1 and 16.63 t ha-1 at Joydebpur, Jamalpur and Ishurdi, respectively). The wider spacing (60 cm x 60 cm) coupled with 25% less than the recommended fertilizer dose produced the lowest yield (two years average). The maximum benefit- cost ratio (two years average) was obtained from the combination of the recommended fertilizer dose and 60 cm x 30 cm spacing, that were 2.93 at Joydebpur and 3.42 at Ishurdi, while at Jamalpur the maximum benefit-cost ratio (two years average) was found maximum from 60 cm x 30 cm spacing with 25% higher than the recommended fertilizer dose (3.12).Bangladesh J.

A field experiment was conducted under late planted lowland situations during wet seasons of 2012 and 2013 at Jorhat to evaluate the performance of 3 late planted sali (kharif) rice varieties (Prafulla, Gitesh and Monoharsali) under 3 planting dates (10, 20 and 30 September) with 2 types of seedling (Nursery seedling and double planted seedling). Results revealed that delaying planting dates from 10 September to 30 September significantly and consistently reduced both grain and straw yields along with all the yield attributing characters during both the years. On an average, the grain and straw yield reduction being 58.3 and 19.3 per cent, respectively. Among the varieties tested, rice variety ‘Monoharsali’ outyielded the variety, ‘Prafulla’ and ‘Gitesh’. Double planted seedlings of 60 days (30 + 30 days) old recorded significantly higher yields and all the yield attributes over the use of 60 days nursery seedling. The highest net return and benefit-cost ratio was recorded when rice variety, ‘Monoharsali’ was transplanted on 10 September using 60 days (30 + 30 days) double planted seedling.

A study on comparative productive efficiency and feasibility of lentil varieties both at relay and minimum tillage were conducted at the Regional Agricultural Research Station, BARI, Ishurdi, Pabna, Bangladesh during the Rabi season of 2007-08 and 2008-09. Three lentil varieties viz. BARI Masur-2, BARI Masur-3 and BARI Masur-4 and two sowing methods viz. relay sowing and furrow sowing (Minimum tillage) were compared. The highest seed yield (1.59 t/ha) was obtained from BARI Masur-4 because of highest number of pods/plant and plant population/m2 while lowest from BARI Masur-2 (1.39 t/ha). The sowing methods had significant effect on the seed yield of lentil. Crops sown in furrows produced higher seed yield (1.60 t/ha) than that of crops in relay sowing. The interaction effect between varieties and sowing methods also had significant effect on the seed yield and yield attributes. The lentil variety BARI Masur-4 when grown in furrows gave the highest seed yield (1.70 t/ha). Though seed yield and gross return were highest in furrow sowing but highest benefit cost ratio (4.67) was found in relay sowing method.Bangladesh J. Agril. Res. 40(2): 271-278 June 2015

Effects of foliar applied macro (NPK) and micro nutrients (Fe, Mn, Zn, Cu and B) at different time on yield, quality and benefit: cost ratio of rainy and winter season guava were evaluated in north western Haryana, India. The two season’s data depicted that physico- chemical characters with respect to fruit set, fruit retention, fruit size, average fruit weight and yield were significantly increased with foliar application of macro and micro nutrients at vegetative, flowering and fruiting stage (T7). The shoot C: N ratio was also found highest with T7 foliar treatment which was followed by T5 in both the seasons. The T7 foliar spray resulted in maximum benefit: cost ratio in both the seasons. Proper fertilization strategies can help fruit growers to get good yield and quality fruits. Bangladesh J. Bot. 50(4): 1159-1164, 2021 (December)
