Development of prescription based fertilizer recommendation for Brinjal (Solanum melongena L.) in mid hills of Himachal Pradesh


Shaifali Rana and Dr. Naveen Datt


The present investigation was conducted at the Experimental Farm of the Department of Soil Science, Chaudhary Sarwan Kumar Himachal Pradesh Krishi Vishvavidyalaya, Palampur (32 6' N latitude and 76 3' E longitude). The soil of the experimental site was Typic Hapludalf, silty clay loam in texture, acidic in reaction, medium in available N, high in available P and low in available K at the initiation of the experiment. The experiment was conducted as per the technical programme and methodology of AICRP on Soil Test Crop Response. The experiment was conducted in two phases. In first phase soil fertility gradient was developed by dividing experimental field into three equal strips and applying graded doses of fertilizers in these strips and growing of exhaust fodder crop Wheat. In the second phase i.e. next season test crop brinjal (var. Hisar shyamal) was grown by dividing each strip into 24 plots having 21 treated and 3 controlled. Response to selected combinations of three levels of FYM (0, 10 and 20 t/ha), four levels of nitrogen (0, 50,100 and 150 kg N ha-1), four levels of phosphorus (0, 30, 60 and 90 kg P2O5 ha-1) and four levels of potassium (0, 25, 50 and 75 kg K2O ha-1) at different fertility levels of brinjal was studied. The initial values of the Alkaline KMnO4 extractable nitrogen ranged from 226 to 289 kg N ha-1, Olsen’s phosphorus ranged from 20 to 40 kg P ha-1 and neutral normal NH4OAc extractable potassium ranged from 148 to 235 kg K ha-1 in the experimental field. The total uptake of N, P and K ranged from 33.9 to 145.2, 5.1 to 21.6 and 23.9 to 82.9 kg ha-1 by brinjal, respectively. In the present investigation the fresh fruit yield ranged from 163.9 to 375.6 q ha-1. The nutrient requirement for production of one quintal of fruit yield of brinjal was found to be 0.30 kg Nitrogen, 0.05 kg Phosphorus and 0.19 kg Potassium. Percent contribution of nitrogen, phosphorus and potassium was 16.71, 26.29 and 14.20 from soil, whereas from other sources as FYM was 7.64, 3.91 and 6.65 percent. Contribution from fertilizer as a percentage was 40.91, 19.11 and 76.23, using with FYM for nitrogen, phosphorus and potassium, respectively. Fertilizer adjustment equations developed for conjoint use of fertilizers with the help of basic data are: FN= 0.74 T – 0.41 SN – 0.19 ON, FP= 0.24 T – 1.38 SP – 0.20 OP, FK= 0.25T – 0.19 SK - 0.09 OK.
