Best suited timing schedule of inorganic NPK fertilizers and its effect on qualitative and quantitative attributes of spring sown sugarcane ( Saccharum officinarum L.)

Abstract

Recently approved variety of sugarcane CPF-248 was grown at agriculture farms of Fatima Sugar Mills, Muzaffargarh, Pakistan. The experiment site was located at Latitude 30°17 0 52.58 00 N and Longitude 70°57 0 44.31 00 E. This experiment was conducted to sort out a suitable fertilizer timing schedule being practiced in the area. This promising variety was evaluated for inorganic N, P and K at different growth stages throughout the year. Each fertilizer treatment had 60 m long 3 rows at random. Center to center distance of each row was 1.35 m which makes total plot size of 1215 m 2 . Three budded cane sets were prepared and dipped in 0.25% solution of Thiophinate methyl. After hot water treating at 52°C for 30 min cane sets were sown in 8 in. deep furrows and buried with almost 1 in. thin layer of soil. There were 5 treatments and each treatment had 3 replications, the experiment was laid out in Randomized Complete Block Design (RCBD). Qualitative and quantitative parameters i.e. germination% age, no. of tillers, stem elongation rate, stem girth, sucrose contents and yield were recorded and periodic trend of these traits were plotted. Significant (P 6 0.05) differences of fertilizer treatments on yield and yield contributing factors were validated. Studied variety responded significantly not only from miller's and breeder's point of view but also from sugarcane grower's point of view. T 2 was comparatively least significant while T 4 was

Nitrogen fertigation schedule and irrigation effects on productivity and economics of spring sugarcane

“…This might be due to increased cane yield generate maximum return. Similar finding was reported by Hussain et al (2017).…”

“…In case of nitrogen scheduling 6 splits application recorded significantly higher commercial cane sugar yield (23.39 and 22.85 t ha -1 during first and second year, respectively) as compared to farmers practice but statistically at par with 8 splits, 10 splits, and 4 splits during both the years. Hussain et al (2017) also observed that different timing schedule of nutrient significantly affect the sugar yield.…”

Improving the Productivity and Sugar Recovery of Cane by Potash Nutrition Under Different Planting Methods

“…Number of millable canes/m 2 increased linearly by the potash application during both plant crop and ratoon crop year. These findings correlate with the findings of Hussain et al (2017), who stated that increased application of potash has a positive and linear effect on number of millable canes. Moreover, 90 by 90 d-pits produced more number of millable canes, which may be due to more seed rate per square meter than that of other plantation schemes.…”

Crescimento, qualidade industrial e balanço de nutrientes de cultivares de cana-de-açúcar sob adubação no Cerrado

“…Com essa demanda crescente de matéria-prima, a otimização dos sistemas produtivos deve ser prioridade, com seleção de cultivares mais adaptadas. Embora o potencial biológico de uma variedade de alto rendimento seja função do material genético, para que expresse o máximo possível em condições de campo, é necessário pacote adequado de insumos e práticas culturais em condição agrícola específica, como, por exemplo, a fertilização e irrigação adequadas (Hussain et al, 2017). Sediyama et al (2009), trabalhos objetivando quantificar os nutrientes removidos pelas culturas na colheita são de grande utilidade para determinar a quantidade necessária de nutrientes a serem restituídos servindo de critério de recomendação para os ciclos sequentes.…”
