The present investigation was carried out to assess the fertility status of the soils of Radaur Block in Yamunanagar, Haryana. The results presented are compiled using the soil test report of two hundred thirteen soil samples collected from 0-15 cm depth by the farmers of Radaur during 2021-22 and bought to Regional Soil Testing Laboratory, CCS HAU, KVK, Karnal for analysis. The observed data revealed that pH of almost 99.53% soil samples were near neutral ranging between 7.1- 8.0. This pH range is very much appropriate for the availability of majority of plant nutrients. Likewise 96.71% soil samples exhibited EC in very low range making the soil very much suitable for agricultural activities. About 8.45 and 29.11% of Radaur block were found deficient in OC and available K content, respectively. OC status of the soil depicts that 83.09% soil samples were in medium range of OC content and only 8.45% samples exhibited high OC content. As far as P availability is concerned nearly 74% of the soil samples were having available P in high range clearly indicating the buildup of P in Radaur soils. Although none of the sample was found deficient in available P content. Contrary to K status of Yamunanagar soils in 2010-11, in 2021-22 exactly 10 years later the scenario has completely changed and a continuous decline in available K status is exhibited. This decline may be due to low rate of K application through fertilizer and manures with K removal by crops exceeding the replenishment. The results revealed that only 9.39% soil samples were in high range and 61.50% in medium range of K availability.
The foliar application of nutrients help the plant leaves to readily absorb the applied nutrients through the nutrient solution and increases the nutrient use efficiency and thus improves the crop yield. The field experiment was conducted for two consecutive years to find out the affect of foliar spray of NPK and micronutrient on cane yield, yield parameters and juice quality of sugarcane during 2019-20 and 2020-21.The present study was carried out on clay loam soils of Research farm of Regional Research Station, CCS Haryana Agricultural University, Karnal, Haryana. The research revealed that cane yield and yield parameters i.e., cane length, and cane weight was significantly affected with the foliar spray of NPK and micronutrient but non-significant effect was observed for cane girth and number of internodes. With respect to juice quality parameters viz., commercial cane sugar (CCS) %, pol % and sugar yield, significantly affected with foliar spray of NPK and micronutrient. The highest cane yield, cane weight and cane length was recorded with the foliar application of 2% NPK (19:19:19) + 0.5% ZnSO4 +1% FeSO4 (78.16 t/ha, 1.21 kg and 207.3 cm) followed by foliar spray of 0.5% ZnSO4 + 1% FeSO4+ 2.5% urea recorded 76.75 t/ha, 1.20 kg and 207.1 cm, respectively. The lowest cane yield (70.68 t/ha) was recorded with the application of recommended dose of fertilizer (RDF) alone. The highest CCS % (12.16), pol % (17.36) and sugar yield (9.51 t/ha) was observed in the treatment 2% NPK + 0.5% ZnSO4 +1% FeSO4. Thus, foliar application with NPK and micronutrient could significantly improve the cane yield, yield parameters and juice quality of sugarcane crop.
Present investigation was carried out at Regional Research Station, Uchani (Karnal) of CCS Haryana Agricultural University, Hisar, India during 2020-21 to assess the effect of method and schedule of fertilizer application on growth, yield attributes and cane yield of summer planted sugarcane (Saccharum officinarum L.) crop under wide spacing (120 cm). The experiment was arranged in split plot design with two methods of fertilizer application (B1-broadcasting and B2- band placement) as main plot treatments and four sub plot treatments which include application of recommended dose of N and K fertilizer (RDF) in different number of splits at different no. of days after planting (DAP) i.e. T1 (five splits), T2 (six splits), T3 (seven splits) and T4 (three splits). Results concluded that majority of growth parameters, yield attributes and cane yield were significantly affected by both main and sub plot treatments at different stages of crop growth period. Treatment B2 registered significantly higher tiller population (110.59 and102.68 000 ha-1 at 60 and 120 DAP respectively), plant height (91.16, 141.18, 400.12 and 412.13 cm at 60, 120, 180 and 240 DAP respectively), no. of millable canes (NMC) (100.79 and 96.58 000 ha-1 in mid-September and at harvesting respectively) cane length (234.64 cm at harvesting) and cane yield (93.16 t ha-1)compared to B1. Among sub plot treatments, T1 outperformed all the other treatments in terms of growth, yield attributes and cane yield. Treatment T1 registered maximum plant height (150.43, 411.0 and 427.45 cm at 120, 180 and 240 DAP respectively), tiller population (104.72 000 ha-1 at 120 DAP), NMC (102.06 and 95.20 000 ha-1 in mid-September and at harvesting respectively) and cane yield (94.83 t ha-1). Germination percentage, cane girth, no. of internodes per cane and length of internodes was not significantly affected either by main or sub plot treatments.

A field study was performed at Regional Research Station, Uchani (Karnal) of CCS Haryana Agricultural University, Hisar, India during 2020-21 to ascertain the role of precision nutrient management in enhancing nutrient availability to plants by amending the schedule and method of N and K fertilization in spring planted sugarcane (Saccharum officinarum L.) crop under wide spacing (120 cm). The experiment was devised under split plot design with three replications. The main plot treatments consisted of two methods of fertilizer placement (B1-broadcasting and B2-band placement) while sub plot treatments included four schedules of application of recommended dose of N and K (RDN+RDK) in five splits (T1), six splits (T2), seven splits (T3) and T4 (RDN in three splits, full dose of P and K at planting). All the main and sub plot treatments showed a remarkable influence on nutrient uptake (kg ha-1), partial factor (kg kg-1) productivity, dry matter accumulation (t ha-1) and plant macro-nutrient content. B1 and T1 among main and sub plot treatments respectively lead to greater nutrient uptake, partial factor productivitie of NPK and highest dry matter yield.
