Abstract

An experiment with nine orchard floor management practices viz., legume intercropping (soybean-peas), turmeric intercropping, fodder intercropping (pearl millet-oats), sod culture (setaria grass), glyphosate, paraquat, weed mulch, manual weeding and weedy check was carried out at Palampur during kharif 2018 to rabi 2019-20 to study their effect on fruit quality and yield of peach. Highest weed population was recorded in weedy check in all the months and lowest weed count was observed in legume intercropping during both the years. Legume intercropping resulted in highest peach yield and quality over rest of the treatments and lowest fruit yield per tree was recorded under weedy check during both the years of study. Uninterrupted growth of weeds reduced the fruit yield by 41.13 per cent during 2019 and by 50.84 per cent during 2020. No phytotoxicity of any herbicide tested (pendimethalin, quizalofop and chlorimuron ethyl to intercrops and directed application of glyphosate and paraquat) was recorded on peach indicating that all the herbicides used were safe for managing weeds in peach orchard.

Abstract

The effect of continuous application of fertilizers and amendments on maize and wheat yield in an acid Alfisol>/i> during 2019-20 was evaluated in a field experiment at the research farm of the Department of Soil Science, CSKHPKV Palampur (HP). The field experiment was conducted on a pre-established long-term fertilizer experiment (1972-73) which comprised of ten treatments up to 1980-81. The eleventh treatment, consisting of 100 per cent NPK (-S) was introduced in kharif, 1981. Thereafter, another treatment, consisting of Beejamrita, Jeevamrita and Ghanajeevamrita (Natural Farming) was introduced in kharif, 2019. The soil of the experimental area was silty clay loam and classified taxonomically as “Typic Hapludalf”. Continuous application of fertilizers and amendments for forty-seven years significantly influenced the yield of maize and wheat. The highest productivity of maize as well as wheat was recorded in the treatment comprising 100 per cent NPK + FYM and was statistically comparable with 100 per cent NPK + lime. Continuous application of N alone over the decades resulted in no yield. However, potassium and sulphur omission from the fertilization schedule for more than four decades resulted in drastic reduction in the yield. The grain and stover/straw yield recorded in natural farming plots was significantly lower as compared to other treatments except control
