“…Whereas in low fertility area, site specific recommendation of fertilizer was higher than POP recommendation and higher growth parameters were observed under the treatment with site specific drip fertigation. This result clearly demonstrated that, irrigation and fertilizer levels have a significant impact on plant growth parameters in low fertility area [7]. By ensuring moisture and nutrient availability, fertigation is regarded to be one of the key aspects that result in increased plant growth [8].…”

Evaluation of site specific drip fertigation system based on GIS integrated nutrient status maps was conducted at Instructional Farm, KCAET, Tavanur, Malappuram, Kerala. Using the spatial variability maps of the soil nutrients, two test plots, one from high fertility zone and one from low fertility zone were identified with the help of GPS for raising the tomato crop. The experimental plot was laid out in a Completely Randomized Design (CRD) with four treatments and four replications. The results showed an increase in yield and growth parameters under site specific drip fertigation treatment in low fertility area due to the adequate fertiliser application than general recommendation. In high fertility area, reduction of fertilizer to site specific requirements has produced almost similar result of general recommendation which indicates that site specific dose was sufficient to produce optimum yield from the crop. Site specific drip fertigation helped to achieve a higher water and nutrient use efficiency with a high economic return of agricultural produce. From this study, it could be concluded that, instead of going with blanket nutrient recommendation, a site specific nutrient recommendation may help the farmers who want to achieve higher profit from unit land area by using optimum inputs, thereby reducing environmental stress due to over fertilizer 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.

“…It is rich in vitamin C, B1, B2 and B6 and minerals such as potassium, phosphorous and magnesium and a good source of high-quality protein (Kahsay, 2019). It is short duration crop with high yield potential as compare to other crops and vegetables (Yadav et al, 2020). The important nutrients required for its cultivation are nitrogen, phosphorus and potassium applied at the recommended rate of 180:80:100 in the form of urea, diammonium phosphate or single super phosphate and murate of potash (Zewide et al, 2012).…”

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.
