RÉSUMÉ
Today, with the advancement of environment pollution and health that is obtained from the improper use of chemical fertilizer, production and use of organic fertilizer is considered as an important approach in the field of soil science in the world’s interest to investors. Research was conducted by using effective management application of vermicompost and neem cake with inorganic fertilizer with objective to enhance the growth and yield of maize crop. It has been concluded from the trial that the different level of vermicompost and neem cake with inorganic fertilizers in the experiment gave the highest value. Effective results were obtained with T9 treatment with combination vermicompost 10 t ha-1, neem cake 500 kg ha-1 with recommended dose of fertilizer NPK 120: 60: 40 kg hhah ha-1. This treatment result shown best plant height with the most leaves, largest stem diameter, longest cob length, heaviest 1000 seed weight, and highest grain yield in compared with the control treatment T1 had the lowest results in all categories. T9 was found to be the best for the improvement of growth and yield of maize therefore, farmers of Prayagraj region can adopt this combination to give the highest yield of Maize.
RÉSUMÉ
An experiment was conducted on sagarika-liquid with inorganic fertilizers during Zaid season 2022 at the central research farm of Department of Soil science and Agricultural chemistry, to enhance the productivity. The design applied was 3x3 RBD having three levels of Sagarika-liquid @2ml, 3ml and 4ml L-1 and N P K @ 50, 75and 100%. The result obtained with treatment T9[N P K @100%+ 2 Spray of Sagarika 4ml l-1] that showed vermicompost in combination resulted in a slight change in soil pH at 0-15 cm and 15-30 cm were found 7.12 and 7.27and EC 0.35 and 0.32 dS m-1 respectively. The significant results were in pore space 47.90 and 45.52%, water holding capacity 46.10 and 43.60%, organic carbon 0.54%, 0.44%, and available nitrogen, phosphorus and potassium was found to be significant among other treatments in Green gram cultivation and soil quality improvement. The maximum yield regarding, gave the best results with respect to plant height 45.34 cm, number of pod plant-1 28.16, and number of seed pod-1 8.45. It gave highest yield 1.96 t ha-1. It was also revealed that the application with organic manures was excellent source for fertilization than fertilizers.
