RESUMO
India is the second- largest producer of rice in the world, with 43.86 million hectares of land under rice cultivation where the crop residue generated is more than 160 million tons per year. The rice straw management is a challenging task in rice-producing regions. So, there is a need for an effective waste disposal technology for converting this waste into some valuable form. Keeping this in view,the present investigation was undertaken during the winter (Rabi) season of 2021-22 and 2022-23 at the Research Farm of the KVK Jagdishpur, Sonipat, Department of Vegetable Science, CCS Haryana Agricultural University, Hisar, Haryana to evaluate the effect of rice straw management on the growth attributes of potato.The seed material of potatocv. “KufriKhyati” was grown with twelve different rice straw treatment combinations. The experimental results revealed that the treatment T1 (Removing of straw + Planting) which was at par with treatment T9 (Urea (50kg/ha) + WD (25lt/ha) + FYM (1ton/ha) + Mixing of chopped straw + Planting) performed superiorly over the other treatments with significantly higher values for growth attributes viz., plant emergence (%), plant height (cm), number of stems per hill and number of leaves per hill.
RESUMO
The experiment entitled “Effect of planting dates and nitrogen levels on potato cv. Kufri Lima” was conducted at Research Farm of the Department of Vegetable Science, Choudhary Charan Singh Haryana Agricultural University, Hisar during winter season of 2020-21. The treatments comprising of three planting dates (25th September, 10th October and 25th October) and four levels of nitrogen (0, 75, 100 and 125% of recommended dose of nitrogen, RDN) were laid out in a randomized block design (factorial) with three replications. Results of study revealed that significantly increase in growth and yield on 10th October planting as compared to earlier and late planting. Total marketable potato tuber yield was recorded with 10th October planting with 100% RDN application (408 q/ha), closely followed by 125% RDN application (407.7 q/ha) and minimum was recorded under control. It can be concluded that 10th October with application of 100% of RDN (150 kg N/ha) provided with highest marketable yield and benefit to cost ratio (1.82). This may be due to higher marketable and total tuber yield under this treatment.
