Description |
The present investigation entitled “Effect of NPK and biofertilizers on potato production” was carried out at Research Farm of the Department of Vegetable Science, CCS Haryana Agricultural University, Hisar during winter season of 2012-13. The ten treatments viz., T1: 50% RD of NPK fertilizers, T2: 100% RD of NPK fertilizers (150:50:100 NPK kg/ha), T3: 150% RD of NPK fertilizers, T4: 50% RD of NPK fertilizers + biofertilizers (Azotobacter + Phosphobacteria), T5: 100% RD of NPK fertilizers + biofertilizers (Azotobacter + Phosphobacteria), T6: 150% RD of NPK fertilizers + biofertilizers (Azotobacter + Phosphobacteria), T7: Without P (100% RD of NK fertilizers), T8: Without K (100% RD of NP fertilizers), T9: Biofertilizers alone and T10: Absolute control (without NPK) were laid out in a Randomized Block Design with four replications. Ten competitive plants were selected randomly from each treatment to record data on various growth and yield parameters. The results reveals that the treatment T6 (150% RD of NPK fertilizers + biofertilizers) was the best among all the treatments for most of the growth and yield parameters under study and showed highest plant height at all intervals, number of leaves and stems at 50 days after planting, stem and leaves weight at harvest, leaf area index, foliage weight, weight of tubers in different grades (up to 25, >50-75 and >75 g tuber weight), total (387.44 q/ha) and marketable tuber yield (366.92 q/ha), maximum nutrients uptake, net return (Rs. 149164/ha) and B:C (3.10) ratio. It was closely followed by T5 (100% RD of NPK fertilizers + biofertilizers) which produced total yield of 360.86 q/ha and produced maximum weight of tubers of >25-50 g grade. There was no significant effect of the treatments on plant emergence and tuber dry matter (%). Further, biofertilizers alone improved total tuber yield by 13.36% over absolute control and thus, it can be concluded that the biofertilizers (Azotobacter, Phosphobacteria) are the advantageous source for nutrients exhaustive crops like potato, when used in combination with inorganic fertilizers or alone. |
