Zinc Application

A field experiment was conducted during two consecutive years of 2015-16 and 2016-17 at Central Potato Research Station, Patna with objective to evaluate theresponse of zinc on potato tuber yield. Significant effect of zinc application was not noticed on plant emergence and plant height of crop at 30 days after planting. However, higher plant height was recorded in the plot which received the zinc as compare to without zinc application. Significant difference in plant height was observed at later stages of crop due to application of zinc at the rate of 6.0 kg/ha along with recommended dose of fertilizers. Similarly, dry matter yield of potato tubers was also recorded consequently higher due to application of higher doses of zinc. Tuber grades of 0-25g and 25-50g were found non-significant irrespective of doses of zinc application in potato. Significant variation in medium and large size tuber yield were recorded due to application of zinc @ 6 kg/ha over without zinc application. About 18.1% increase in marketable tuber yield of potato was found due to application of zinc @ 6.0 kg/ha as compare to without zinc application. About11.3% and 13.7% increase in the total tuber yield of potato was observed due to application of zinc @ 4.5 and 6.0 kg/ha, respectively over without zinc application. However, no significant variation in pooled yield was found with application of zinc up to 3.0 kg/ha over without zinc application. The highest net return (Rs. 36.0×103/ha) and net benefit cost ratio (2.52) was recorded due to application of zinc @ 6.0 kg/ha as compare to without zinc. Application of zinc @ 6.0 kg/ha along with recommended dose of NPK may be found more beneficial for potato cultivation under Eastern Indo-Gangetic plains of India.

A field experiment was carried out during 2015-16 and 2016-17 at ICAR-Central Potato Research Station, Patna, Bihar, in randomized block design with four replications with objective to quantity the optimum requirement of nitrogen to potato crop. Significantly the highest plant height was recorded with nitrogen level of 300 kg/ha. Distributions of the smallest size of tuber yield of potato were decreasing with increasing the level of nitrogen. There was about 26.0% more yield of the smallest size tuber of potato was recorded with zero nitrogen as compare to the highest level of nitrogen i.e. 300 kg/ha. Increasing the nitrogen over the level of 150 to 225 kg per hectare, increasing the yield of tuber gradually slower rate than nitrogen level from 0 to 150 kg/ha. Total and marketable tuber yield of potato were increasing significantly with increasing level of nitrogen up to 150 kg/ha. There was no significant difference in marketable tuber yield was found for nitrogen level between 150 and 225 kg/ha. Highest (1.66) net benefit cost ratio was also recorded with level of nitrogen @ 150 kg/ha in potato. Hence, application of nitrogen @ 150 kg/ha was found statistically and economically more beneficial for potato cultivation in Eastern Indo-Gangatic plain of India.

Phosphorus (P) is an important element that is applied in the form of di-ammonium phosphate or single super phosphate in potatoes. An experiment was conducted at ICAR-Central Potato Research Station, Patna, Bihar during Rabi, 2017-18 and 2018-19 to evaluate invariably use of phosphorus fertilizers in potato crop. The use of phosphorus is often applied at higher rate than its uptake from the soil. Therefore, experiment was undertaken with the objective to optimize and utilize soil phosphorus more efficiently. Potato variety Kufri Khyati was planted in three replications with eight different treatments of fertilizer phosphorus. Data on tuber yield (t/ha) and tuber number (lacs/ha) was recorded. The maximum tubers were recorded at 20% of recommended dose of phosphorus i.e. 5.14 lacs/ha followed by 100% recommended dose of phosphorus (4.56 lacs/ha). The tuber yield was maximum at 100% recommended dose of phosphorus (33.53 t/ha) followed by 50% recommended dose of phosphorus (31.35 t/ha), which was at par with the yield obtained at 20% (30.29 t/ha) to 40% (29.98 t/ha) of recommended dose of phosphorus. The recorded results showed that the omission of phosphorus does not have any significant reduction in the yield as compare to tuber numbers. Therefore it may be recommended that in high P soils, the maintenance dose of 20 % of recommended dose of P is sufficient to harvest economic yield.

The experiment was conducted at the Hill Agricultural Research Station, Khagrachari during two winter seasons of 2010-11 and 2011-12 to find out suitable planting system of the component crops for increasing productivity and profitibility for hill farmers of Bangladesh. Three intercrop combinations viz., (i) maize paired row + 2 rows sweet potato, (ii) maize normal row +1 row sweet potato and (iii) sweet potato normal row + 1 row maize were evaluated against their respective sole crops. In all combinations, light availability was more at early growth stage and reduced gradually with the advancement of canopy development of maize. Light availability was minimum at 100 days after emergence and thereafter slightly increased in three intercrop combinations. Among intercrop combinations, light availability to sweet potato canopy was more in maize paired row + 2 rows sweet potato combination through out the crop period which enhance tuber formation, tuber bulging and tuber yield. Contrary, sweet potato vines provide a mulch cover for maize which preserve soil moisture and reduce weed infestation producing higher yield and yield components of maize. Maize yield (cob yield: 19.82 t ha-1, grain yield: 8.98 t ha-1), tuber yield of sweet potato (17.11 t ha-1) and maize equivalent yield (cob equivalent yield: 42.63 t ha-1, grain equivalent yield: 15.82 t ha-1) were the highest in maize paired row + 2 rows sweet potato combination. Similarly, the highest gross return (for cob: Tk. 1,27,890 ha-1, for grain: Tk. 1,58,200 ha-1), gross margin (for cob: Tk. 87,890 ha-1, for grain: Tk.1,08,200 ha-1) and benefit cost ratio (for cob: 3.20, for grain: 3.16) were also obtained from the same combination.

A field experiment was conducted at Horticulture Research Station (HRS), Dailekh, in Mid-Western hills of Nepal during 2019 and 2020, to evaluate the performance of ten potato genotypes for plant, and tuber yield characters. The potato genotypes were evaluated during spring season in a randomized complete block design with three replications. The genotypes showed highly significant difference for all the traits except tuber emergence. The mean squares for the year were also significant for all the traits except tuber emergence, stem numberplant -1 and total tuber yield. The interaction between genotypes and years did not show significant differences in all the traits except stem numberplant -1. Genotype CIP392797.22 produced more marketable yield (27.5 tha -1) and total tuber yield (30.2tha -1) than all other genotypes. The genotype CIP392797.22 is characterized as medium maturing, oval-shaped and dark red-skinned one with shallow eye depth in the tuber, and it imparted 13.2% higher marketable yield than Kufri Jyoti (24.3 tha -1). Thus, the genotype CIP392797.22 is recommended to evaluate on-farm for the verification and up-scaling among farmers at Mid-Western Nepal.

The increasing global demand for water in many sectors has become a universal concern. Challenge is to develop advanced production systems that allow rice production to be sustained in the face of waning water availability. With the intention to find the efficient water saving technology and establishment method, a field experiment was conducted at Zonal Agricultural Research Station, V. C. Farm, Mandya, University of Agricultural Sciences, and Bangalore during Kharif 2018. The experiment was laid out in split plot design with three main plot irrigation treatments and five sub plot rice establishment treatments. The paddy variety used was ‘MTU 1001’. Objective was to study the irrigation and establishment methods on growth of rice. The results revealed that, continuous flooding recorded significantly higher plant height (80.67 cm) at harvest. Whereas, alternate wetting and drying (AWD) recorded higher leaf area index (5.06), CGR at 30 to 60 DAS, 60 to 90 DAS and 90 DAS to harvest (1.49,  3.50 and 2.47 g m-2 day-1, respectively), NAR at 30 to 60 DAS and 60 to 90 DAS (7.19 and 4.37 mg cm-2 day-1, respectively). Among establishment methods, manual transplanting recorded higher plant height (81.82 cm), LAI (5.70), DME (55.77), AGR at 30 DAS (0.36 g day-1), CGR at 30 to 60 DAS and 60 to 90 DAS (1.73 and 3.94 g m-2 day-1, respectively) and LAD at 30 to 60 DAS, 60 to 90 DAS and 90DAS to harvest (49.50, 128.70 and 272.80, respectively). However, mechanical transplanting recorded significantly more number of tillers m-2 (765.67), NAR at 30 to 60 DAS and 60 to 90 DAS (9.96 and 4.41 mg cm-2 day-1, respectively). AWD method of irrigation in mechanical transplanting and manual transplanting are found to be better among all other methods due to the higher growth and development.

An experiment was conducted during December, 2017 to May, 2018 at the Agronomy field of Sher-e-Bangla Agricultural University, Dhaka to evaluate the performance of white maize variety under different spacing and integrated fertilizer management. The experiment comprised two different factors; (1) two plant spacing viz. S1 (60 cm × 20 cm) and S2 (40 cm × 20 cm) and (2) four levels of integrated fertilizer application viz. T1: All chemical fertilizer (recommended dose), T2: maize straw compost +½ of recommended dose,T3: cowdung+½ of recommended dose and T4: vermicompost +½ of recommended dose. The experiment was set up in split plot design with three replications. Results revealed that both the individual and the interaction treatments had effect on different growth and yield parameters of white maize. In respect of the spacing effect, the wider spacing S1 showed higher plant height, number of leaves plant-1, cob length, cob circumference, number of grains cob-1, shelling percentage, 100 grains weight and harvest index where S2 showed higher grain yield. The integrated fertilizer had significant effect on different growth and yield parameters of white maize. In respect of the integrated fertilizer effect, the highest values in plant height, number of leaves plant-1, leaf area index and crop growth rate, cob length, cob circumference, number of grains cob-1, shelling percentage, 100 grains weight, grain yield, stover yield and biological yield were highest with T3 whereas, the lowest corresponding values were recorded from T2. Among the interaction treatments, higher seed yield was obtained with the interaction treatment S2T3 (10.01 t ha-1) while S1T2 showed significantly the lowest seed yield (5.27 t ha-1). The highest seed yield was mostly attributed to the number of grains per cob (328-433) and 100 seed weights (29.67-33.33 g).
